Psychiatry billing in 2026 reflects one of the most meaningful compliance and reimbursement shifts the specialty has seen in years. Between the long-awaited rate increase, expanded flexibility for crisis care, and shorter remote monitoring thresholds, practices finally have new revenue opportunities. However, strict enforcement of psychotherapy time rules, mandatory drug waste modifiers, and detailed Medical Decision Making (MDM) documentation requirements mean precision is no longer optional. Understanding the most important psychiatry CPT® codes, modifiers, and 2026 updates will determine whether your practice sees improved reimbursement—or preventable denials.

The 2026 “Rate Reset” for Psychiatry

CMS implemented a long-awaited reimbursement increase for 2026:

Category	Increase
Advanced APM Participants	+3.85%
All Other Physicians	+3.26%

This is the first meaningful upward adjustment in several years. For psychiatry practices that rely heavily on time-based Evaluation & Management (E/M) services and psychotherapy CPT® codes, the impact is significant.

Time-intensive care models are finally being stabilized rather than eroded by annual cuts.

Psychotherapy CPT® Codes (2026 Enforcement)

CPT® Code	Description
90832	Psychotherapy, 30 minutes
90834	Psychotherapy, 45 minutes
90837	Psychotherapy, 60 minutes

The 53-Minute Rule for 90837

To bill 90837, documentation must reflect at least 53 minutes of psychotherapy. A 52-minute session must be downcoded to 90834 under the midpoint rule.

Auditors are strictly enforcing psychotherapy time thresholds in 2026, and failure to meet the minimum documented time is triggering downcoding and recoupment.

Audio-Only Crisis Care (Modifier 93)

CPT® Code	Description
90839	Psychotherapy for crisis; first 60 minutes
+90840	Each additional 30 minutes

These crisis psychotherapy codes are now permanently included in CPT Appendix T.

When video is unavailable, practices may bill crisis psychotherapy via audio-only telephone by appending Modifier 93. This ensures reimbursement for emergency telephonic interventions during acute psychiatric distress.

Short-Window Remote Therapeutic Monitoring (RTM)

CPT® Code	Description
98985	RTM device supply for 2–15 days in 30-day period
98978	RTM treatment management (20+ minutes)
99470	Remote management, 10–19 minutes

The former 16-day minimum barrier has been removed. Psychiatry practices can now bill monitoring of CBT apps, mood trackers, sleep logs, and digital therapeutics for as few as 2–15 days per month using 98985.

If 12 minutes of review occur, bill 99470. If 20 or more minutes are documented, bill 99457. These may not be billed in the same month.

Interventional Psychiatry Compliance (Spravato & Injectables)

The -JW / -JZ rule is a hard enforcement requirement in 2026.

Scenario	Required Modifier
Drug partially wasted	-JW
No drug wasted	-JZ

Claims missing the appropriate modifier will be automatically rejected. Spravato and long-acting injectables are primary audit targets.

Upstream Drivers and MDM Elevation

CMS has rebranded Social Determinants of Health as Upstream Drivers.

Documenting factors such as Z59.0 (homelessness) or Z62 (problems related to upbringing) can elevate Risk in Medical Decision Making when these conditions complicate psychiatric management.

This may support 99214 or 99215 levels even when clinical stability appears otherwise controlled.

Dermatology billing in 2026 reflects both reimbursement stabilization and structural payment reform. While the Physician Fee Schedule increase benefits E/M-heavy practices, significant technical changes affect acne procedures, skin substitute reimbursement, radiation therapy reporting, and modifier enforcement. If your team is still using last year’s templates, small documentation gaps could translate into preventable denials.

This guide outlines the most important Dermatology CPT® codes and modifiers for 2026, structural payment changes, and the compliance rules practices must adopt immediately to protect reimbursement.

The 2026 Physician Fee Schedule Stabilization

• +3.85% increase for physicians participating in Advanced APMs
• +3.26% increase for all other physicians

This marks the first meaningful rate increase in several years. Dermatologists who rely heavily on 99214–99215 visits for psoriasis, acne, eczema, and biologic management will see measurable stabilization in revenue—if documentation supports level selection.

However, increased scrutiny on time-based billing means even minor documentation gaps can result in downcoding.

Evaluation & Management (E/M) CPT® Codes

CPT® Code	Description
99202–99205	New patient office visits
99212–99215	Established patient office visits
99241–99245	Consultations (payer dependent)

2026 Time Enforcement Reminder

To bill 99215 by time, documentation must reflect at least 40 minutes of total physician or qualified health professional time on the date of service. If 39 minutes or less is documented, the visit must be billed as 99214.

Auditors are increasingly verifying exact minute counts.

CPT® Terminology Update: Acne Extraction (10040)

The descriptor for CPT® 10040 has been revised for 2026. The term “Acne surgery” has been replaced with “Extraction” of inflammatory or non-inflammatory acne lesions.

Why This Matters

Documentation should now reflect “acne extractions” rather than “surgery.” Surgical terminology may trigger edits expecting operative prep, sterile technique documentation, and higher complexity indicators inconsistent with simple lesion extraction.

Skin Biopsies

CPT® Code	Description
11102	Tangential biopsy, first lesion
11103	Each additional tangential lesion
11104	Punch biopsy, first lesion
11105	Each additional punch lesion
11106	Incisional biopsy, first lesion
11107	Each additional incisional lesion

Biopsy Hierarchy Rule

If multiple biopsy techniques are performed, the highest-valued primary code should be reported first. Add-on codes must correspond to technique and lesion count appropriately.

Radical Shift: Skin Substitute Reimbursement

CMS reclassified biological skin substitutes as incident-to medical supplies.

Reimbursement is now bundled at $127.28 per square centimeter, replacing ASP + 6% methodology.

Practices must evaluate acquisition cost vs reimbursement immediately to avoid margin erosion.

Surface Radiation Therapy CPT® Codes

CPT® Code	Description
77436	Surface radiation therapy planning
77437	Superficial radiation treatment delivery (≤150 kV)
77438	Orthovoltage radiation delivery (>150 kV–500 kV)
+77439	Add-on: Ultrasound image guidance

Common Dermatology Billing Modifiers

Modifier	Common Use
-25	Separate E/M on same day as procedure
-59	Distinct procedural service
-JW	Drug waste reported
-JZ	No drug waste
-50	Bilateral procedures

Common ICD-10-CM Codes in Dermatology

ICD-10 Code	Description
L40.0	Psoriasis vulgaris
L70.0	Acne vulgaris
C44.91	Basal cell carcinoma, unspecified site
L20.9	Atopic dermatitis, unspecified
D48.5	Neoplasm of uncertain behavior of skin

2026 Dermatology Billing & Compliance Tips

• Document full 40 minutes for 99215 when billing by time.
• Use updated “extraction” terminology for CPT® 10040.
• Validate skin substitute acquisition costs against bundled rate.
• Ensure correct biopsy hierarchy reporting.
• Apply -JZ/-JW modifiers consistently.
• Select proper telehealth POS.

Mental health billing in 2026 reflects one of the most transformative years behavioral health providers have seen in recent memory. Expanded Remote Therapeutic Monitoring (RTM), stronger valuation for crisis care, updated drug-waste modifier enforcement, and evolving Medical Decision Making (MDM) standards are all reshaping reimbursement. At the same time, payers are tightening scrutiny around psychotherapy time documentation, interventional psychiatry, and telehealth reporting. If your workflows haven’t been updated for 2026, denials and underpayments are likely already affecting your revenue.

This guide outlines the most important Mental Health CPT® codes and modifiers for 2026, along with the documentation and compliance rules that protect reimbursement.

The 2026 Physician Fee Schedule Update

CMS implemented meaningful reimbursement adjustments for 2026:

• +3.85% conversion factor increase for physicians in Advanced APMs
• +3.26% increase for all other physicians

This represents the first substantial increase in several years and directly benefits psychiatry E/M services and psychotherapy reporting. However, higher valuation often leads to increased audit scrutiny. Practices must ensure documentation standards rise alongside payment increases.

Psychiatric Diagnostic Evaluation CPT® Codes

CPT® Code	Description
90791	Psychiatric diagnostic evaluation (without medical services)
90792	Psychiatric diagnostic evaluation (with medical services)

When billing 90792, documentation must clearly reflect medical services such as medication management, prescription adjustments, or medical decision-making complexity. Failure to document medical components can trigger downcoding to 90791.

Psychotherapy CPT® Codes and 2026 Midpoint Enforcement

CPT® Code	Description
90832	Psychotherapy, 30 minutes
90834	Psychotherapy, 45 minutes
90837	Psychotherapy, 60 minutes

Midpoint Rule Enforcement

• To bill 90837, documentation must reflect at least 53 minutes.
• 52 minutes or less requires downcoding to 90834.
• Time must reflect psychotherapy time only—not administrative tasks.

Payers are increasingly auditing time-based psychotherapy services. Templates should prompt exact session length documentation to avoid systematic denials.

Remote Therapeutic Monitoring (RTM) Expansion

CPT® 98978 – Behavioral Health RTM

• Monitoring cognitive/behavioral therapy via FDA-cleared digital therapeutics
• Tracks mood, sleep, therapy adherence, and engagement metrics

New 2026 Short-Duration RTM (98985)

• 98985 – Device supply for 2–15 days of cognitive/behavioral monitoring

These codes allow reimbursement for structured between-session monitoring. However, device qualification and patient consent must be documented clearly.

Remote Management Tier (99470)

• 99470 – First 10–19 minutes of remote data review per month

If time reaches 20 minutes, bill 99457 instead. These services cannot be billed together in the same month.

Interventional Psychiatry Billing (TMS & Ketamine)

Transcranial Magnetic Stimulation (TMS)

• 90867 – Initial TMS treatment session
• 90868 – Subsequent TMS delivery

Medical necessity documentation must clearly establish treatment-resistant depression and prior failed therapies.

Spravato / Ketamine Compliance

For 2026, -JW and -JZ modifiers are enforced as hard-stop edits.

• Used portion billed normally
• Unused portion reported with -JW
• If no waste occurs, append -JZ

Crisis Psychotherapy CPT® Codes (90839–90840)

CPT® Code	Description
90839	Psychotherapy for crisis, first 60 minutes
90840	Each additional 30 minutes

These services received increased valuation for 2026.

Audio-Only Crisis Billing

Now included in CPT® Appendix T, these services may be reported with Modifier 93 when video is unavailable.

Upstream Drivers and MDM Risk Elevation

Formerly SDOH, Upstream Drivers may elevate Risk in MDM scoring. Housing instability (Z59.0) or trauma history (Z62) that meaningfully complicates care can support higher-level E/M services when documented clearly.

Telehealth POS Reporting Rules

• POS 10 – Patient at home
• POS 02 – Patient outside the home

Incorrect POS selection can reduce reimbursement by 20–30% due to widening facility vs. non-facility payment differences.

2026 Mental Health Summary Table

2026 Status	Code(s) / Rule	Impact on Behavioral Health
Rate Increase	+3.26% to +3.85%	Major payment boost
Short-Term RTM	98985 / 98978	App-based CBT monitoring
Management Tier	99470	10-minute remote review billing
Audio-Only Crisis	90839 + Modifier 93	Phone crisis reimbursement
Drug Modifiers	-JW / -JZ	Mandatory for ketamine waste reporting

2026 Mental Health Billing Tips

• Document 53+ minutes for 90837.
• Append G2211 for longitudinal psychiatric care.
• Link Upstream Driver Z-codes to treatment complexity.
• Use POS 10 correctly to avoid underpayment.
• Report drug waste accurately for ketamine therapies.

Final Thoughts

Keeping your mental health CPT® codes and modifiers aligned with 2026 standards protects reimbursement and reduces audit risk. Between RTM expansion, crisis billing flexibility, midpoint enforcement, and injectable compliance, behavioral health billing is more complex—but also more opportunity-rich—than ever.

Internal medicine billing spans preventive care, chronic disease management, hospital follow-ups, remote monitoring, and longitudinal care coordination. Few specialties rely more heavily on Evaluation & Management (E/M) services and time-based reimbursement. For 2026, internal medicine enters a long-awaited stabilization year—with meaningful Physician Fee Schedule increases and expanded remote monitoring flexibility. Understanding how these updates affect CPT® coding, modifiers, and documentation is essential to protecting reimbursement and avoiding preventable denials.

The 2026 Physician Fee Schedule Stabilization Increase

The 2026 Physician Fee Schedule delivers the first meaningful across-the-board reimbursement increase in several years:

• +3.85% conversion factor increase for physicians in Advanced Alternative Payment Models (APMs)
• +3.26% increase for all other physicians

This adjustment directly benefits internal medicine practices that rely heavily on time-based CPT® E/M codes. However, certain non-time-based services remain subject to the -2.5% efficiency adjustment, particularly diagnostic testing.

For practices with high E/M volume, this stabilization year presents a revenue opportunity—but only if documentation supports correct code selection.

Evaluation and Management CPT® Codes

CPT® Code	Description
99202–99205	New patient office visits
99212–99215	Established patient office visits
99221–99223	Initial hospital care
99231–99233	Subsequent hospital care
99238–99239	Hospital discharge services
99495–99496	Transitional Care Management

Time Rule Reminder: CPT® 99215 requires at least 40 minutes of total time on the date of service. Being one minute short requires downcoding. Time must include all qualifying provider activities.

Short-Duration Remote Monitoring (CPT® 99445)

The elimination of the “16-day barrier” is one of the most operationally impactful updates for 2026.

CPT® Code	Description
99445	Device monitoring for 2–15 days of data transmission within 30 days

Practices can now bill for shorter monitoring intervals, expanding RPM feasibility for chronic but stable patients.

Ideal Use Cases

• Short-term blood pressure stabilization
• Medication titration monitoring
• Post-discharge weight monitoring

Important: Devices must transmit data automatically. Manual patient logs do not qualify.

Mandatory Modifier -JZ vs. -JW

All single-dose injectable drug claims must include:

• -JW (drug discarded)
• -JZ (no waste)

Claims missing these modifiers are automatically rejected.

2026 Internal Medicine Billing & Compliance Tips

• Document total time clearly for time-based CPT® services.
• Track RPM transmission days carefully.
• Link Upstream Driver Z-codes to treatment impact.
• Use POS 10 accurately for home telehealth visits.
• Never omit -JW or -JZ modifiers.

Final Thoughts

Internal medicine in 2026 benefits from reimbursement stabilization and expanded chronic care flexibility. The Physician Fee Schedule increase, remote monitoring adjustments, and clearer documentation standards collectively strengthen revenue capture for longitudinal adult care.

However, these gains only materialize when CPT® coding, modifiers, and documentation are aligned. Small errors continue to drive preventable denials—even in a stabilization year.

Trademark notice: CPT is a registered trademark of the American Medical Association.

Pediatric billing in 2026 reflects a major shift toward whole-family, longitudinal, and complexity-driven care. Between new vaccine counseling reimbursement, expanded caregiver training services, updated Medical Decision Making (MDM) recognition, and remote monitoring flexibility, pediatricians now have clearer pathways to capture the full scope of work performed. However, those opportunities also introduce new compliance risks. Accurate coding, proper modifier use, and updated workflow alignment are essential to prevent denials and protect revenue in today’s evolving reimbursement environment.

The 2026 Physician Rate Reset

After several years of reimbursement pressure, CMS implemented a 3.85% overall Physician Fee Schedule increase for 2026. This update improves physician work valuation and strengthens payment for cognitive services.

However, non-time-based services such as certain screenings remain subject to a -2.5% efficiency adjustment. Pediatric practices must model both adjustments into financial projections to accurately forecast revenue.

Pediatric Preventive Care CPT® Codes

CPT® Code	Description
99381–99385	New patient preventive visits (age-specific)
99391–99395	Established patient preventive visits (age-specific)

Preventive visits should be paired with appropriate ICD-10 codes such as Z00.121 (with abnormal findings) or Z00.129 (without abnormal findings). Documentation must clearly reflect age-specific screenings and anticipatory guidance.

New 2026 Immunization Counseling CPT® Codes (90482–90484)

CPT® Code	Description
90482	3–10 minutes of vaccine counseling
90483	11–20 minutes of counseling
90484	More than 20 minutes of counseling

These new codes allow reimbursement for vaccine counseling even when no vaccine is administered. This is especially important when parents decline immunization but substantial physician counseling is provided.

Compliance Rule

If vaccine counseling occurs during a well or sick visit on the same day, Modifier -25 must be appended to the E/M service.

Immunization Administration CPT® Updates

CPT® Code	Description
90471	First vaccine administered
90472	Each additional vaccine
90460–90461	Administration with physician counseling (under 18)
90380	RSV Nirsevimab 0.5 mL (neonates)
90381	RSV Nirsevimab 1 mL (infants up to 24 months)

Report RSV prophylaxis with diagnosis code Z29.11. Claims must include -JW if waste occurs and -JZ if no waste occurs for single-dose injectables.

The 2026 “Upstream Drivers” MDM Update

CMS now recognizes Social Determinants of Health as “Upstream Drivers.” Documentation of Z55–Z65 codes may elevate a visit to Moderate Complexity (99214) when directly impacting management decisions.

ICD-10 Code	Example Impact
Z62	Upbringing challenges impacting ADHD care
Z55	Literacy barriers affecting medication adherence
Z59.4	Food insecurity complicating obesity or diabetes care

2026 Pediatric Summary Table

2026 Status	Code(s) / Rule	Impact on Pediatric Practice
New Counseling	90482–90484	Bill for vaccine education even if shot is refused
New Caregiver Care	96202–96203	Bill for parent training without child present
Short-Term Monitoring	99445	2–15 day post-acute monitoring
Rate Increase	+3.85%	Overall physician reimbursement boost
Mandatory Modifier	-JZ	Required for zero-waste injectables

Final Thoughts

Pediatric reimbursement in 2026 reflects a whole-family model of care. With new CPT® counseling codes, caregiver training reimbursement, remote monitoring flexibility, and stronger recognition of social risk in MDM, pediatricians now have clearer pathways to report the full complexity of their work.

Maintaining accurate CPT® coding, modifier compliance, and documentation alignment ensures your practice captures appropriate reimbursement while remaining audit-ready in a rapidly evolving regulatory environment.

Trademark notice: CPT is a registered trademark of the American Medical Association.

Family practice billing in 2026 is no longer limited to traditional office visits. Primary care now encompasses longitudinal care complexity, caregiver training, behavioral health integration, social risk documentation, and flexible remote monitoring models—all of which directly impact reimbursement. As Medical Decision Making (MDM) logic evolves and CMS refines payment recognition for whole-person care, documentation precision and correct CPT® selection are more critical than ever.

If your coding framework hasn’t been updated for 2026 changes, denials, downcoding, and underpayment are inevitable.

Evaluation & Management (E/M) Codes

Most family medicine revenue flows through E/M services. In 2026, MDM documentation and time thresholds remain critical audit triggers.

CPT® Code	Description
99202–99205	New patient office visits
99212–99215	Established patient office visits
99381–99387	Initial preventive visits
99391–99397	Periodic preventive visits
99417	Prolonged services add-on
G2211	Visit complexity add-on for longitudinal care

2026 “16-Minute” Time Gate

When selecting E/M based on time, thresholds must be met exactly. For example, CPT® 99213 requires a minimum of 20 minutes. Documentation of 19 minutes may result in automatic downcoding during payer audit. Time rounding is a common audit vulnerability.

G2211 Restrictions

G2211 may be billed alongside problem-oriented visits (99202–99215) when longitudinal care responsibility is documented. It may not be billed with preventive codes (99381–99397). Improper pairing is a frequent denial trigger.

The 2026 “Upstream Drivers” MDM Boost

CMS now formally recognizes Social Determinants of Health as “Upstream Drivers.” When these factors materially impact treatment, they elevate risk scoring under the MDM framework.

In 2026, documented social instability that complicates adherence qualifies as Moderate Risk.

Example: A hypertensive patient with food insecurity (Z59.4) requiring medication adjustment supports Moderate Complexity, often aligning with CPT® 99214.

Clear documentation of housing instability, transportation barriers, financial strain, or caregiver limitations now carries measurable reimbursement impact.

Short-Duration Remote Monitoring (RPM)

Remote care continues expanding in primary care, especially for short-term monitoring scenarios.

CPT® Code	Description
99445	Remote monitoring supply, 2–15 days
99454	Remote monitoring supply, 16–30 days
99470	First 10 minutes of remote management
99457	First 20 minutes of remote management

CPT® 99445 fills short-term monitoring gaps (e.g., medication titration). Only one supply code (99445 or 99454) may be billed per 30-day period.

Devices must transmit data electronically. Patient-reported manual logs do not qualify.

Caregiver Training Services (CTS)

CPT® Code	Description
96202	Caregiver training services, initial session
96203	Each additional caregiver training session

These codes allow physicians to bill for caregiver education without the patient present when chronic illness or functional impairment necessitates training.

This formalizes compensation for care coordination previously unreimbursed in primary care.

Behavioral Health Integration (BHI)

CPT® Code	Description
99484	General Behavioral Health Integration

CPT® 99484 continues supporting integrated mental health oversight in primary care. When longitudinal oversight is documented, G2211 may also apply.

Vaccines & Immunization Administration

• 90471 – First vaccine
• 90472 – Each additional vaccine
• 90460–90461 – Pediatric counseling

Mandatory -JZ Rule

Append -JW if medication is wasted. Append -JZ when no waste occurs. Missing -JZ now results in automated rejection.

---

Telehealth POS Rules

• POS 02 – Patient at home (facility rate)
• POS 10 – Patient outside home (non-facility rate)

Incorrect POS selection impacts reimbursement rates and audit risk.

---

Respiratory Multiplex Testing

CPT® 87428 combines Flu A/B, COVID-19, and RSV testing. Billing separate single-virus tests may trigger bundling edits.

---

2026 Family Practice Summary Table

2026 Update	Code(s)	Impact
Short-Term RPM	99445	2–15 day monitoring option
Upstream Drivers	Z-Codes	Supports Moderate Risk MDM
Caregiver Training	96202–96203	Bill caregiver sessions
Telehealth POS	02 / 10	Affects payment rate
Mandatory Modifier	-JZ	Required for no-waste injections

---

Family Practice Billing Tips for 2026

• Document Upstream Drivers clearly when they alter treatment plans.
• Do not pair G2211 with preventive services.
• Track exact time thresholds when billing by time.
• Use proper pediatric vaccine counseling codes.
• Adopt multiplex testing during respiratory season.

---

Final Thoughts

Family medicine in 2026 reflects the evolution toward comprehensive, longitudinal care. Between social risk recognition, caregiver reimbursement, remote monitoring flexibility, and behavioral health integration, primary care now has expanded mechanisms to capture the true scope of work performed.

Staying proactive with documentation precision, CPT® compliance, and modifier accuracy ensures your practice remains audit-ready while protecting revenue.

Nephrology billing in 2026 reflects a transition year for the specialty. While the Physician Fee Schedule includes a -2.5% efficiency adjustment for many E/M services, the ESRD Prospective Payment System (PPS) base rate has increased. At the same time, new transplant evaluation codes and expanded remote monitoring options are reshaping how nephrologists report complex care.

From CKD management to dialysis oversight and transplant clearance, correct coding, modifier selection, and detailed documentation are essential to protect reimbursement and avoid audit exposure. If your team is still using last year’s workflows, 2026 changes require immediate attention.

Evaluation and Management CPT® Codes in Nephrology

E/M services remain the foundation of nephrology reimbursement. Whether managing CKD progression, adjusting antihypertensive regimens, or overseeing dialysis-related complications, documentation must clearly support medical decision-making or total time.

CPT® Code	Description
99202–99205	New patient office visits
99212–99215	Established patient office visits
99221–99223	Initial inpatient services
99231–99233	Subsequent inpatient services
99238–99239	Hospital discharge services
99495–99496	Transitional Care Management (TCM)

2026 “16-Minute Rule” Reminder

When billing based on time, thresholds must be met precisely. Reporting 99215 requires at least 40 minutes of total physician or qualified healthcare professional time on the date of service. Falling short—even by one minute—requires reporting 99214 instead.

New 2026 Kidney Transplant Evaluation Standards

2026 introduces formal recognition of the intensive work required for kidney transplant clearance. Historically bundled into high-level E/M visits, transplant coordination now requires documentation that reflects multidisciplinary evaluation, diagnostic testing, and risk stratification.

This includes cardiovascular clearance, infectious disease screening, psychosocial assessment coordination, and documentation required for UNOS waitlist approval.

Practices must ensure documentation captures the total scope of work performed—not just the face-to-face visit.

Dialysis and ESRD Management CPT® Codes

Dialysis services remain the financial core of most nephrology practices. Documentation precision directly affects reimbursement and audit exposure.

CPT® Code	Description
90935	Hemodialysis with single evaluation
90937	Hemodialysis with repeated evaluations
90945	Peritoneal dialysis, single evaluation
90947	Peritoneal dialysis, repeated evaluations
90951–90966	Monthly ESRD-related services (MCP)
90989	Home dialysis training, initial
90993	Additional dialysis training sessions

2026 ESRD PPS Base Rate

The ESRD PPS base rate for 2026 is $281.71, reflecting approximately a 2.2% increase. However, compliance oversight has increased alongside reimbursement adjustments.

Home Dialysis Training Audit Alert (90989)

CMS requires training logs to include date, duration, and specific training topics. A general statement of “training completed” is insufficient and may trigger recoupment.

Remote Monitoring CPT® Codes for 2026

Remote monitoring plays an expanding role in nephrology, particularly during post-discharge transitions.

CPT® Code	Description
99445	Device supply and transmission, 2–15 days
99454	Device supply and transmission, 16–30 days
99470	First 10 minutes of remote management
99457	First 20 minutes of remote management

Automatic transmission is required. Manual patient logs do not qualify for reimbursement.

Common ICD-10-CM Codes in Nephrology

ICD-10 Code	Description
N18.3	CKD stage 3
N18.4	CKD stage 4
N18.5	CKD stage 5
N18.6	End-stage renal disease
E87.5	Hyperkalemia
Z99.2	Dialysis dependence
Z94.0	Kidney transplant status

Medical Necessity Reminder

A correctly reported CPT® code can still deny if the ICD-10 pairing does not support payer policy. Ensure laboratory services such as 84132 (Potassium) are linked appropriately to diagnoses like E87.5.

Nephrology Billing Modifiers That Prevent Denials

Modifier	Common Use in Nephrology
-25	Separate E/M on dialysis day
-95	Telehealth services (when applicable)
-JW	Drug amount discarded
-JZ	Zero drug waste (mandatory for single-dose injectables)
-59	Distinct procedural services

Final Thoughts

Nephrology billing in 2026 reflects modernization alongside heightened compliance scrutiny. Between dialysis oversight, transplant evaluation, remote monitoring expansion, and stricter drug-waste reporting, documentation must support every CPT® code billed.

Staying current protects reimbursement, reduces denials, and ensures your practice reflects the full complexity of kidney care.

Orthopedic billing in 2026 reflects some of the most meaningful coding shifts in recent years. While total joint arthroplasty and fracture care remain core revenue drivers, the expansion of short-duration Remote Therapeutic Monitoring (RTM), refined sacroiliac joint fusion reporting, and new intramedullary limb-lengthening codes require immediate operational adjustments. If your team is relying on last year’s coding habits, denials and audit exposure will increase quickly.

This updated guide outlines the most important Orthopedic CPT® codes and modifiers for 2026 so your practice can reduce denials, strengthen documentation, and protect reimbursement.

Evaluation & Management (E/M) Codes in Orthopedics

Orthopedic E/M services remain subject to the broader Physician Fee Schedule adjustments for 2026. Same-day procedures, fracture care global periods, and prolonged service billing require especially careful documentation.

CPT® Code	Description
99202–99205	New patient office visits (levels 2–5)
99212–99215	Established patient office visits (levels 2–5)
99417	Prolonged services add-on (each 15 minutes beyond maximum time)

Prolonged Services Documentation Standard

To report 99417 in 2026, documentation must reflect a full 15-minute increment beyond the maximum time threshold of the base code (such as 99205 or 99215). Partial increments do not qualify. Time must be clearly documented — vague statements such as “extended visit” will not support reimbursement.

New 2026 Short-Duration RTM Codes

The most impactful orthopedic update for 2026 is the expansion of musculoskeletal Remote Therapeutic Monitoring (RTM). These codes create new reimbursement pathways for post-operative rehab and conservative management — but only if billed correctly.

CPT® Code	Description
98985	RTM device supply, musculoskeletal system (2–15 days)
98977	RTM device supply (16–30 days)
98979	RTM treatment management, first 10 minutes
98980	RTM treatment management, first 20 minutes

Important Billing Rule

You must select either 98985 (2–15 days) or 98977 (16–30 days) in a single calendar month. Both codes cannot be reported together. Management codes (98979, 98980) must meet time thresholds and interactive communication requirements.

SI Joint Fusion (27279) Documentation Standard

For minimally invasive sacroiliac joint fusion, documentation requirements are stricter in 2026.

CPT® Code	Description
27279	Minimally invasive SI joint fusion

The operative note must clearly state that the implant pierces the cortices of both the ilium and the sacrum (transarticular fixation). Intra-articular placement alone does not qualify for 27279 reporting.

Failure to specify cortical penetration is a growing audit trigger and can result in recoding or denial.

New Intramedullary Limb-Lengthening Codes

2026 introduces long-awaited specificity for internally controlled limb-lengthening procedures.

CPT® Code	Description
27458	Unilateral femoral osteotomy with insertion of intramedullary lengthening device
27713	Unilateral tibial osteotomy with insertion of intramedullary lengthening device

These codes replace unlisted reporting and improve reimbursement clarity, but documentation must detail device type and laterality.

Injection Compliance & Drug Waste Modifiers

-JW vs. -JZ Rule

• Use -JW when a portion of a single-dose vial is discarded.
• Use -JZ when no drug waste occurs.

Failure to append one of these modifiers will trigger automatic rejection.

Ultrasound Guidance (76942)

When billing 76942, image storage is mandatory. If no image is archived in PACS or EHR, payers may recoup the guidance portion of the claim.

Reverse Shoulder Arthroplasty Documentation

For accurate inpatient DRG assignment, operative notes should specify implant configuration, component type, and construct orientation.

Orthopedic Billing Modifiers That Prevent Denials

Modifier	Common Orthopedic Use
-25	Separate E/M on same day as procedure
-JW	Discarded drug amount
-JZ	No discarded drug amount
-50	Bilateral procedure
-RT / -LT	Laterality specification
-59	Distinct procedural service

2026 Orthopedic Billing & Compliance Tips

• Document transarticular fixation for 27279.
• Never combine 98985 and 98977 in the same month.
• Store ultrasound images when billing 76942.
• Append -JW or -JZ for all single-dose injectable drugs.
• Ensure prolonged services meet full 15-minute increments before reporting 99417.

Final Thoughts

Orthopedic CPT® codes and modifiers for 2026 introduce greater flexibility — but also greater audit exposure. Between RTM expansion, SI fusion clarification, limb-lengthening specificity, and stricter modifier enforcement, documentation precision is now directly tied to reimbursement protection.

Building updated templates, charge capture safeguards, and modifier review protocols into your workflow will prevent avoidable denials and protect high-dollar orthopedic revenue.

Dialysis billing in 2026 reflects two major financial shifts: a positive adjustment to the ESRD Prospective Payment System (PPS) base rate and the permanent adoption of virtual direct supervision. At the same time, physician services remain subject to the -2.5% efficiency adjustment applied across much of the Medicare Physician Fee Schedule. These layered changes affect ESRD Monthly Capitation Payments (MCP), remote monitoring, training services, and transition-of-care billing all at once.

Understanding how these updates interact is essential for nephrology groups managing ESRD monthly capitation payments (MCP), home dialysis oversight, drug administration compliance, and transition-of-care services. Small documentation gaps or modifier errors can trigger predictable denials.

2026 ESRD PPS Base Rate Increase

The 2026 Final Rule establishes a new ESRD PPS Base Rate of $281.71, representing approximately a 2.2% increase from 2025. This increase applies to the bundled dialysis facility payment, not directly to physician E/M reimbursement.

Why This Matters for Nephrology Groups

• The increase helps offset labor and supply inflation.
• Oral-only drugs are fully integrated into the bundle.
• Physician work RVUs remain affected by the -2.5% efficiency adjustment.

This creates a split environment: facility reimbursement improves modestly, while physician-side payments remain compressed. Practices that understand how to capture every compliant MCP visit and related service become financially more stable.

Monthly ESRD-Related Services (MCP CPT® Codes)

MCP CPT® codes remain the foundation of dialysis physician billing and are reported once per calendar month based on patient age and visit frequency requirements.

CPT® Code	Description
90951–90953	ESRD services, under 2 years
90954–90956	Age 2–11
90957–90959	Age 12–19
90960–90962	Age 20+
90963–90966	Home dialysis MCP

2026 MCP Documentation Clarification

CMS has reinforced that qualifying face-to-face visits must include documentation addressing dialysis adequacy. Notes should reflect review of measures such as URR or Kt/V and demonstrate assessment of dialysis prescription effectiveness.

If documentation addresses only blood pressure or anemia management without referencing dialysis adequacy, the visit may not qualify toward MCP frequency requirements.

Remote Monitoring and Short-Duration RPM CPT® Codes

The addition of 99445 and 99470 expands remote oversight flexibility during dialysis transition periods.

CPT® Code	Description
99445	Remote monitoring supply, 2–15 days
99470	First 10 minutes of remote management

These codes are especially valuable post-discharge or during modality changes when patients require short-duration monitoring that previously failed to meet the 16-day threshold required under 99454.

Dialysis Training CPT® Codes

CPT® Code	Description
90989	Initial home dialysis training
90993	Additional training session

Documentation for 90989 must reflect completion of a structured curriculum. If training is discontinued early, reporting must shift to per-session billing using 90993.

Mandatory Modifier -JW vs. -JZ

Modifier	Application in Dialysis
-JW	Used when part of a single-dose vial is discarded
-JZ	Required when no waste occurs

This requirement heavily impacts ESAs and IV iron. Claims missing either modifier are rejected under CMS edits.

Transition of Care CPT® Limits

Nephrologists may bill 99495 or 99496 for hospital-to-home transitions. However, these codes cannot be billed in the same month as a full MCP code by the same provider.

Common ICD-10-CM Codes for Dialysis

ICD-10 Code	Description
N18.6	End-stage renal disease
Z99.2	Dependence on renal dialysis
N17.9	Acute kidney failure
I12.9	Hypertensive chronic kidney disease
Z94.0	Kidney transplant status

2026 Dialysis Billing & Compliance Tips

• Document dialysis adequacy (Kt/V or URR) at qualifying MCP visits.
• Bill only one MCP per calendar month.
• Use 99445 strategically during fluid-management transitions.
• Append -JW or -JZ on all single-dose injectable claims.
• Do not combine TCM and full MCP in the same month by the same provider.

Final Thoughts

Dialysis reimbursement in 2026 reflects a nuanced balance: a positive facility-level base rate adjustment alongside physician efficiency reductions. Permanent virtual supervision and expanded remote monitoring offer meaningful operational flexibility.

Practices that align documentation, modifiers, and workflow controls with updated CPT® and CMS rules can protect reimbursement and reduce predictable denials.

Pathology billing in 2026 reflects a major shift toward precision reporting, artificial intelligence integration, and genome-wide molecular diagnostics. Advances in digital slide analytics, Optical Genome Mapping (OGM), and expanded Proprietary Laboratory Analyses (PLA) codes have created new CPT® pathways that replace older bundled or unlisted reporting methods. If your pathology team is still relying on prior-year assumptions, you may already be exposed to preventable denials.

This updated guide outlines the most impactful Pathology CPT® codes and modifiers for 2026, including digital pathology analytics, cytogenomic genome-wide testing, molecular enforcement rules, and compliance clarifications that directly affect reimbursement.

Clinical Pathology Core Codes

Routine laboratory services remain foundational in pathology billing but are subject to increased reimbursement scrutiny under 2026 payer efficiency adjustments.

CPT® Code	Description
80053	Comprehensive metabolic panel
83036	Hemoglobin A1c
84443	Thyroid-stimulating hormone
85025	Complete blood count with differential
85610	Prothrombin time

Heavy Metal Testing Update

Codes 83015 and 83018 have been updated for 2026 to explicitly include additional analytes such as antimony and gadolinium. Ensure laboratory test menus and charge descriptions reflect the revised language to prevent audit discrepancies.

Anatomic Pathology & Surgical Specimens

CPT® Code	Description
88304	Surgical pathology, level III
88305	Surgical pathology, level IV
88307	Surgical pathology, level V
88309	Surgical pathology, level VI
88341	Immunohistochemistry, each additional antibody

Reflex immunohistochemistry and add-on stains remain under heightened scrutiny in 2026. Standing reflex panels without individualized documentation continue to trigger payer audits.

Reflex Testing Compliance

Each additional stain or molecular test must be supported by documentation explaining how it contributed to establishing or clarifying the final diagnosis. Blanket language such as “reflex per protocol” is frequently insufficient.

AI-Assisted Digital Pathology

AI-based slide analysis tools for pre-screening, quantification, and biomarker detection now have more defined reporting pathways in 2026.

Digital Pathology Analytics Codes

Emerging reporting options—including codes such as X504T—allow separate reporting of algorithmic analysis when payer contracts permit. These services are not universally bundled into 88305.

Important: Billing AI services without confirming contractual recognition may lead to automatic bundling edits.

Optical Genome Mapping (OGM)

CPT® Code	Description
81354	Cytogenomic genome-wide analysis using optical genome mapping

Optical Genome Mapping detects large structural variants not visible through standard karyotyping or targeted sequencing.

Critical Update: Reporting OGM using 81479 instead of 81354 in 2026 may result in immediate denial when a specific code exists.

Molecular Pathology & PLA Enforcement

CPT® Code	Description
81524	CNS tumor DNA methylation analysis (Category I)

New PLA codes (0575U–0613U) must be used when applicable. Tier 1, Tier 2, or unlisted codes are not acceptable substitutes when a specific PLA exists.

Modifier Updates for 2026

Modifier	When Used
-26	Professional component
-TC	Technical component
-90	Reference laboratory
-91	Repeat diagnostic test
-XS	Separate structure

Mandatory Drug Modifier Enforcement (-JW / -JZ)

-JW must be appended when any portion of a drug is discarded. -JZ must be used when zero waste occurs. Claims lacking one of these modifiers may be automatically rejected.

Final Thoughts

Pathology billing in 2026 reflects rapid modernization across diagnostics. AI-assisted slide interpretation, genome-wide cytogenomic mapping, PLA enforcement, and stricter modifier requirements require proactive review of both CPT® updates and payer contracts.

Staying current protects reimbursement, reduces audit exposure, and supports innovation without sacrificing compliance.
