Jan 9, 2026

When it comes to neurology medical billing, precision is vital. Incorrect code usage can lead to missed reimbursement, claim rejections, or audit risk—especially when you’re working with time-based services, remote monitoring, and EEG-related reporting. For 2026, neurology practices should review the latest CPT® updates, including expanded remote monitoring options and new Category III codes tied to EEG services.

Neurology denials aren’t “random”—they’re driven by predictable documentation and time-reporting gaps.

We see the same breakdowns repeatedly: remote monitoring minutes not supported, unclear device supply duration, mismatched payer policies for emerging Category III EEG services, and telehealth modifier errors that trigger automatic edits.

Guarantee: We’ll identify your top neurology denial drivers and give you a clear plan to reduce rejections and improve payment speed.

Neurology 2026 CPT® Code Updates

Remote monitoring continues to expand in 2026. In addition to the familiar Remote Therapeutic Monitoring (RTM) codes used for 16–30 days of monitoring, 2026 adds options that better reflect shorter-duration monitoring and lower time thresholds for treatment management.

That matters because payers are increasingly strict about two things: (1) whether the documented monitoring period matches the code’s required duration, and (2) whether staff/provider time is supported in the clinical record. When either one is missing, claims tend to deny quickly—especially when monitoring is billed month-over-month.

Here are key remote monitoring updates to know for 2026:

98975 – RTM initial setup and patient education on use of equipment
98976 – RTM device supply for monitoring the respiratory system, 16–30 days in a 30-day period
98977 – RTM device supply for monitoring the musculoskeletal system, 16–30 days in a 30-day period
98978 – RTM device supply for monitoring cognitive behavioral therapy (CBT), 16–30 days in a 30-day period
99445 – Remote monitoring device supply and transmission for a shorter monitoring duration (2–15 days in a 30-day period)
98980 – RTM treatment management services, first 20 minutes of clinical staff or physician/QHP time in a calendar month
98981 – RTM treatment management services, each additional 20 minutes in a calendar month
99470 – Remote monitoring treatment management, first 10 minutes (lower threshold than the 20-minute requirement tied to 98980/99457-style reporting)

Remote Monitoring Documentation That Payers Expect

Tip: For remote monitoring claims, document (1) the monitoring window (days), (2) what was monitored and why, (3) the clinical response or care-plan change, and (4) staff/QHP time logs that support any time-based management services.

Remote monitoring reimbursement breaks when your record doesn’t prove time, duration, and clinical action.

We see denials when teams bill supply/transmission without clearly supporting the monitoring duration—or bill time-based management without a defensible time trail and clinical decision-making tied to the data.

Guarantee: We’ll pinpoint the exact documentation gaps causing remote monitoring denials and show you what to fix so the next cycle pays.

New Neurology-Specific Category III Codes for 2026

Neurology also gained new Category III (emerging technology) codes in 2026. These are especially relevant for facilities and providers reporting continuous EEG monitoring and AI-supported EEG waveform analysis.

X461T–X466T – Continuous EEG monitoring services (Category III)
X504T – Augmentative algorithmic (AI-supported) analysis of encephalographic (EEG) waveforms (Category III)

Because Category III codes often have payer-specific coverage rules, denials frequently occur when prior authorization is missing, documentation doesn’t match the descriptor intent, or the payer requires an alternate reporting pathway. That doesn’t mean you shouldn’t bill them—it means you should treat them as “high-attention” services that require tighter front-end checks.

Category III Reality Check

Tip: Before submitting Category III EEG claims, confirm payer coverage rules, authorization requirements, and any documentation checklist expectations. A “covered drug/service” is not the same as a “cleanly payable claim.”

Category III EEG claims can stall fast if payer requirements aren’t handled up front.

We often see delays tied to missing authorization, mismatched documentation, or payer-specific edits that flag emerging technology codes for manual review.

Guarantee: We’ll identify where your Category III EEG workflow is vulnerable and provide a fix plan that reduces delays and rework.

Neurology CPT® Code Ranges for 2026

The CPT® code ranges below are frequently used for neurology and neuromuscular procedures. Always confirm payer guidance and the most current CPT® descriptors before filing claims.

95700-95811 – Long-term EEG Procedures and Sleep Medicine Testing
95812-95830 – Routine EEG Procedures
95829-95836 – Electrocorticography
95851-95857 – Testing Range of Motion
95860-95872 – Electromyography Procedures
95873-95887 – Guidance Procedures for Chemo Denervation and Ischemic Muscle Testing Procedures
95905-95913 – Nerve Conduction test
95919-95924 – Autonomic Function testing procedure
95925-95937 – Evoked Potentials and Reflex testing procedure
95938-95941 – Intraoperative Neurophysiology procedure
95970-95984 – Neurostimulators Analysis-Programming procedure
95990-95999 – Other Neurology and Neuromuscular procedure
96000-96004 – Motion analysis procedure
96020-96020 – Functional Brain Mapping

These ranges are helpful for quick reference, but claims success still depends on the “supporting story” in the note—medical necessity, accurate test indication, and complete technical/professional documentation where applicable.

The right code range doesn’t guarantee payment—documentation does.

We see denials when test indications are vague, documentation is incomplete for technical vs professional components, or payer policies require additional elements that weren’t captured in the note.

Guarantee: We’ll identify your most common neurology documentation gaps that lead to denials and show you how to fix them.

Neurology CPT® Modifiers for 2026

CPT® modifiers help make a code more specific. In 2026, Modifier 93 and 95 remain important for telehealth reporting, but it’s also worth noting how Appendix T impacts audio-only reporting for certain services.

93 – Audio-only telemedicine (used when the payer allows real-time audio-only reporting for the service)
95 – Synchronous telemedicine service rendered via real-time interactive audio and video telecommunications

Pro tip for 2026: Many behavioral health and neuropsychological testing codes (including 96130–96133) are recognized in CPT® Appendix T for audio-only reporting with Modifier 93, which can help support compliant telehealth billing when video is not available.

Telehealth Modifier Risk in Neurology

Tip: Payers often reject telehealth claims when place of service, telehealth indicators, and modifiers don’t align. Build a consistent telehealth checklist so your workflow isn’t dependent on memory.

Telehealth claims deny quickly when modifiers and payer rules don’t match.

We see avoidable rejections when Modifier 93 or 95 is used inconsistently, or when payer-specific telehealth requirements aren’t reflected in the claim’s supporting details.

Guarantee: We’ll identify where telehealth coding and modifier usage is creating denials—and provide a correction plan.

A Quick 2026 “Watch List” for Neurology Teams

Most neurology revenue-cycle issues in 2026 won’t come from a lack of codes—they’ll come from missed payer expectations. Use this watch list to reduce preventable denials and rework:

Short-duration monitoring support: Make sure documentation supports the monitoring window and the clinical rationale for monitoring.
Time-based management defensibility: Keep a reliable time trail and clearly link monitoring data to clinical decisions or care-plan updates.
Category III coverage friction: Confirm payer-specific requirements (including authorization) for EEG-related emerging technology services.
Telehealth modifier alignment: Don’t assume Modifier 93 or 95 is accepted for every service—verify payer rules and code eligibility.

If your team misses one payer rule, you’ll feel it in denials—and delayed cash flow.

We help neurology practices eliminate preventable breakdowns: documentation gaps, modifier errors, and remote monitoring workflow issues that stop claims from paying.

Guarantee: We’ll identify your highest-risk neurology billing issues for 2026 and provide a clear plan to fix them.

Neurology Billing Tips for 2026

Build a remote monitoring checklist. Include duration support, device documentation, and a consistent approach to time logging.
Defend time-based services. Ensure time is traceable and tied to clinical action, not just “reviewed.”
Treat Category III EEG codes as high-attention claims. Confirm authorization, coverage, and documentation requirements before submission.
Standardize telehealth modifier usage. Align Modifier 93 and 95 with payer rules and ensure claim fields match telehealth requirements.
Reduce rework with templates. Build documentation prompts into note templates so compliance doesn’t depend on memory.

If these steps aren’t built into your workflow, denials will keep coming back.

Most teams know the rules. Denials persist because documentation and billing workflows don’t consistently reflect payer expectations for remote monitoring, telehealth, and emerging EEG services.
