When it comes to neurology medical billing, precision is vital. Incorrect code use can lead to missed reimbursement, claim rejections, or audit risk, especially with time-based services, remote monitoring, and EEG reporting. For 2026, neurology practices should review the latest CPT® updates, including expanded remote monitoring options and new Category III codes for EEG services. Each code below has been checked against current CMS and AMA sources.
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 speed up payment.

Neurology 2026 CPT® Code Updates
Remote monitoring continues to expand in 2026, with new codes for shorter monitoring periods and lower time thresholds. There are two families: remote physiologic monitoring (RPM), which tracks physiologic data such as blood pressure or heart rate, and remote therapeutic monitoring (RTM), which tracks musculoskeletal or respiratory status, therapy adherence or response, or cognitive behavioral therapy.
Payers are strict about two things: whether the documented monitoring period matches the code’s required number of days, and whether staff or provider time is supported in the record. When either is missing, claims deny quickly, especially when monitoring is billed month after month.
| CPT® Code | Description |
|---|---|
| 99453 | RPM initial setup and patient education |
| 99445 / 99454 | RPM device supply with daily recording or alert transmission, 2–15 days (new for 2026) / 16–30 days in a 30-day period |
| 99470 | RPM treatment management, first 10 minutes in a calendar month (new for 2026) |
| 99457 / 99458 | RPM treatment management, first 20 minutes / each additional 20 minutes |
| 98975 | RTM initial setup and patient education |
| 98984 / 98976 | RTM device supply, respiratory system, 2–15 days (new for 2026) / 16–30 days |
| 98985 / 98977 | RTM device supply, musculoskeletal system, 2–15 days (new for 2026) / 16–30 days |
| 98986 / 98978 | RTM device supply, cognitive behavioral therapy, 2–15 days (new for 2026) / 16–30 days |
| 98979 | RTM treatment management, first 10 minutes in a calendar month (new for 2026) |
| 98980 / 98981 | RTM treatment management, first 20 minutes / each additional 20 minutes |
- Report only one supply code per 30-day period (the 2–15 day or the 16–30 day code), and only one first-tier management code per month (the 10-minute or the 20-minute code).
- Don’t bill RPM and RTM for the same patient in the same period.
Remote Monitoring Documentation That Payers Expect
Tip: For remote monitoring claims, document (1) the monitoring window in days, (2) what was monitored and why, (3) the clinical response or care-plan change, and (4) staff or provider time logs that support any time-based management.
Remote monitoring reimbursement breaks when your record doesn’t prove time, duration, and clinical action.
We see denials when teams bill supply codes without clearly supporting the monitoring duration, or bill time-based management without a defensible time trail and clinical decisions 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.

EEG CPT® Codes for 2026
| CPT® Code | Description |
|---|---|
| 95812 | EEG, extended monitoring; 41–60 minutes |
| 95813 | EEG, extended monitoring; 61–119 minutes |
| 95816 | EEG, awake and drowsy |
| 95819 | EEG, awake and asleep |
| 95822 | EEG, recording in coma or sleep only |
| 95700 | Long-term EEG: setup, patient education and takedown by a technologist |
| 95705–95716 | Long-term EEG: technical recording and monitoring, by duration and whether video and technologist monitoring are included |
| 95717–95726 | Long-term EEG: physician or QHP review, interpretation and report, by duration and with or without video |
Document the exact recording time for 95812 and 95813, and append -26 or -TC when the professional and technical parts are billed separately.
New Neurology-Specific Category III Codes for 2026
Neurology also gained new Category III (emerging technology) codes. They’re especially relevant for practices that manage implanted sub-scalp EEG systems or use AI-supported EEG analysis.
| CPT® Code | Description |
|---|---|
| 1004T | Electronic analysis of an implanted sub-scalp continuous bilateral EEG monitoring system; without programming |
| 1005T / 1006T | With programming, first 15 minutes / each additional 15 minutes face-to-face |
| 1007T | EEG from an implanted sub-scalp system: physician or QHP review of recorded events, spike and seizure detection analysis, and report |
| 1008T | Remote monitoring of a sub-scalp EEG system: device fitting, initial setup, and patient education |
| 1009T | Remote monitoring of a sub-scalp continuous EEG system: data review, spike and seizure detection, interpretation and report, up to 30 days |
| 1041T | Augmentative algorithmic (AI) analysis of EEG waveforms to identify the source and spread of epileptiform activity, with interpretation and report, from a previously performed EEG (effective July 1, 2026) |
Because Category III codes often have payer-specific coverage rules, denials frequently occur when prior authorization is missing, documentation doesn’t match the code descriptor, or the payer requires a different reporting pathway. That doesn’t mean you shouldn’t bill them; it means they’re “high-attention” services that need tighter front-end checks.
Category III Reality Check
Tip: Before submitting Category III EEG claims, confirm payer coverage, authorization requirements, and documentation expectations. Many payers still list the sub-scalp EEG codes as investigational, and Medicare contractors price these codes individually. When a Category III code describes the service, CPT requires it instead of an unlisted code.
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 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.

Neurostimulator Analysis and Programming
| CPT® Code | Description |
|---|---|
| 95970 | Electronic analysis of implanted neurostimulator, without programming |
| 95976 / 95977 | Electronic analysis with simple / complex cranial nerve neurostimulator programming |
| 95983 / 95984 | Electronic analysis with brain neurostimulator programming, first 15 minutes / each additional 15 minutes |
| 95836 | Electrocorticography from an implanted brain neurostimulator, unattended, with review and report, up to 30 days |
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 current CPT® descriptors before filing claims.
| Code Range | Category |
|---|---|
| 95700–95726 | Long-term EEG monitoring |
| 95782–95811 | Sleep medicine testing |
| 95812–95830 | Routine EEG procedures |
| 95829, 95836 | Electrocorticography |
| 95851–95857 | Range of motion testing and Tensilon test |
| 95860–95872 | Electromyography (EMG) |
| 95873–95887 | Guidance for chemodenervation, ischemic muscle testing, and EMG performed with nerve conduction studies |
| 95905–95913 | Nerve conduction studies |
| 95919–95924 | Autonomic function testing |
| 95925–95939 | Evoked potentials and reflex testing |
| 95940–95941 | Intraoperative neurophysiology monitoring |
| 95954–95967 | Special EEG tests and magnetoencephalography |
| 95970–95984 | Neurostimulator analysis and programming |
| 95990–95999 | Other neurology and neuromuscular procedures |
| 96000–96004 | Motion analysis |
| 96020 | Functional brain mapping |
These ranges are helpful for quick reference, but claim success still depends on the supporting story in the note: medical necessity, an accurate test indication, and complete technical and 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 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.
Common ICD-10 Codes in Neurology
| ICD-10 Code | Description |
|---|---|
| G40.011 / G40.019 | Localization-related idiopathic epilepsy with seizures of localized onset, intractable, with / without status epilepticus |
| G40.111 / G40.119 | Localization-related symptomatic epilepsy with simple partial seizures, intractable, with / without status epilepticus |
| G40.211 / G40.219 | Localization-related symptomatic epilepsy with complex partial seizures, intractable, with / without status epilepticus |
| G40.909 | Epilepsy, unspecified, not intractable, without status epilepticus |
| R56.9 | Unspecified convulsions |
| G43.909 | Migraine, unspecified, not intractable, without status migrainosus |
| G35.A | Relapsing-remitting multiple sclerosis (new October 1, 2025) |
| G35.D | Multiple sclerosis, unspecified (replaces G35) |
| G20.A1 | Parkinson’s disease without dyskinesia, without mention of fluctuations |
| Z45.42 | Encounter for adjustment and management of neurostimulator |
Neurology CPT® Modifiers for 2026
CPT® modifiers make a code more specific. Modifiers 93 and 95 remain important for telehealth, and the professional and technical component modifiers matter for EEG, EMG and nerve conduction testing.
| Modifier | Description |
|---|---|
| -93 | Audio-only telemedicine, when the payer allows real-time audio-only reporting for the service |
| -95 | Synchronous telemedicine via real-time interactive audio and video |
| -26 / -TC | Professional component (interpretation) / technical component (equipment and technologist), for EEG, EMG, nerve conduction and evoked potential testing |
| -52 | Reduced service, such as a study that is cut short |
| -25 | Significant, separately identifiable E/M on the same day as a procedure (for example, an office visit plus botulinum toxin injections) |
| -59 / -XS | Distinct procedural service; CMS prefers the more specific -XE, -XP, -XS or -XU when one applies |
Pro tip for 2026: CPT® Appendix T lists codes that can be reported as audio-only with modifier 93, including the neurobehavioral status exam (96116). Psychological and neuropsychological testing evaluation codes (96130–96133) aren’t on that list, so confirm each payer’s rules before billing them as audio-only.
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 doesn’t depend 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.
Guarantee: We’ll identify where telehealth coding and modifier use 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 reason 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 emerging EEG services.
- Telehealth modifier alignment: Don’t assume modifier 93 or 95 is accepted for every service; verify payer rules and code eligibility.
- Diagnosis code updates: Replace G35 with the new multiple sclerosis codes in templates and problem lists.
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.

Frequently Asked Questions
What is the CPT code for an EEG in 2026?
A routine EEG is billed with 95816 (awake and drowsy) or 95819 (awake and asleep). Longer recordings use 95812 (41–60 minutes) or 95813 (61–119 minutes), and long-term monitoring uses the 95700–95726 series.
What are the new neurology CPT codes for 2026?
New for 2026 are the short-duration remote monitoring codes (99445, 98984–98986), the 10-minute management codes (99470, 98979), and Category III codes 1004T–1009T for sub-scalp EEG systems. 1041T for AI-supported EEG analysis took effect July 1, 2026.
Do I need a new diagnosis code for multiple sclerosis?
Yes. Since October 1, 2025, G35 requires more characters. Use G35.A for relapsing-remitting MS, the G35.B and G35.C codes for progressive forms, or G35.D when the type isn’t documented.
Final Thoughts
Neurology billing in 2026 is increasingly shaped by remote monitoring, telehealth modifier compliance, and emerging EEG technologies. Keeping your CPT® coding current is important, but building a workflow that consistently supports medical necessity, time reporting, and payer requirements is what protects revenue long term.

“My husband and I have a small practice but we were looking for a medical billing company to consult us. We originally started with a local company with some satisfaction. However, our biggest problem was that they wanted us to change our existing EMR to software that they worked with. Quest National Services worked with our existing software so that we didn’t have to make expensive changes to our infrastructure. That saved us a lot of time and headache. I would definitely say that was one of the main reasons for why we switched and why we continue to work with Quest. As a small practice, they helped us without draining our resources.”
