Neurology is entering 2026 as one of the most financially complex — and financially fragile — specialties in medicine.
Clinical demand has never been higher. Administrative burden has never been heavier. And the gap between what neurology practices earn clinically and what they collect financially has never been wider.
Here are the seven trends reshaping neurology RCM in 2026, and what the practices managing them successfully are doing differently.
1. The G35 MS Code Deletion Is a Test of Billing Infrastructure
Few RCM events in 2026 have had as immediate or as wide an impact on neurology as the deletion of ICD-10 code G35 (Multiple Sclerosis), effective October 1, 2025.
Claims with dates of service on or after October 1, 2025 using G35 are automatically rejected as invalid. The replacement codes require documented MS phenotype (relapsing-remitting, secondary progressive, primary progressive, etc.) and activity status — specificity that G35 as an umbrella code never required.
For practices with large MS populations receiving ongoing treatment, this transition created a silent mass-denial event. Claims submitted using standing documentation templates, prior authorization references, and EHR defaults that hadn't been updated to reflect the code deletion are generating automatic rejections. And because the denial reason is an invalid code rather than a medical necessity dispute, the path to correction is straightforward — but only if the practice catches it quickly.
The practices that navigated this without revenue disruption had one thing in common: automated ICD-10 validation that fires before submission, not after denial. The practices still recovering from the transition relied on manual billing review that didn't catch the change until a denial batch revealed the pattern weeks later.
2. Neurology's Denial Rate Is Among the Highest in Medicine — and Getting Worse
Neurology claim denials occur at a 35% initial rate — among the highest of any outpatient specialty. From 2022 to 2024, the number of providers reporting increasing denials jumped from 42% to 77%. And approximately 40% of denied neurology claims are never reprocessed.
The drivers are structural: EEG codes that require duration-specific documentation, EMG/NCS codes that require precise study-count calculations, chemodenervation codes that require anatomically-correct procedure code selection and matched drug billing, and diagnostic imaging PA requirements that vary by payer and change throughout the year.
Each of these is a category where manual billing is structurally unable to achieve consistent accuracy at neurology's case volume. The practices closing the gap between the 35% denial rate they have and the 5% benchmark they should aspire to are those that have moved from reactive denial management to upstream claim validation.
3. The 2026 CMS Fee Schedule Creates a Site-of-Service Decision Point
The 2026 CMS Final Rule introduced a -2.5% efficiency adjustment to work RVUs on nearly all non-time-based codes. Critically, E/M and time-based codes are exempt — meaning neurology's high-volume chronic disease management visits (which routinely support complex, time-based billing) are not directly penalized by the efficiency adjustment.
But the indirect practice expense restructuring creates a facility vs. non-facility payment differential that neurology groups providing services across office, hospital, and ASC settings need to model carefully. Neurology is projected to see an overall payment increase of approximately 1% in 2026 — but that average conceals a shift that benefits office-based services while reducing payments for facility-based encounters.
For neurology groups that perform long-term EEG monitoring, intravenous infusions, or procedural services in both office-based and facility settings, understanding where the fee schedule changes create incentive to shift site of service is the difference between capturing the 2026 rate improvements and absorbing unexpected reductions.
4. Remote Patient Monitoring Is an Emerging — and Underutilized — Revenue Category
Neurology is increasingly well-positioned for remote patient monitoring revenue. The specialty manages large populations of patients with chronic neurological conditions — epilepsy, MS, Parkinson's, migraines, stroke recovery — who benefit from continuous monitoring and management outside the clinic.
The 2026 CMS Final Rule expanded RPM reimbursement in ways that directly benefit neurology: new device supply code 99445 for patients with 2–15 days of data in a 30-day period, and new management code 99470 for 10-minute clinical interactions — both of which make RPM more accessible for patients who don't consistently transmit full monthly data.
Remote therapeutic monitoring (RTM) is separately available for neurological conditions via CPT 98978. For migraine practices specifically, migraine tracking app data that syncs with physician review systems is billable under the RPM/RTM framework.
The practices capturing this revenue are those that have built RPM as a governed billing workflow — tracking transmission days, documenting management time, and submitting codes monthly — rather than treating remote monitoring as a clinical supplement that never reaches the billing system.
5. Payer Scrutiny on AI-Assisted Diagnostics Creates New Documentation Requirements
Neurology is at the frontier of AI integration in clinical practice — AI-assisted EEG interpretation, automated neuroimaging analysis, and ML-based seizure detection are entering clinical workflows. And payers are watching.
CMS and commercial payers are actively auditing AI-assisted diagnostic services in neurology in 2026. The core requirement: physician review must be documented for all AI-assisted outputs, and the final clinical decision must be made and recorded by the treating provider — AI-generated interpretations alone do not satisfy documentation requirements.
This creates a specific compliance risk for practices that have implemented AI diagnostic tools without updating their documentation workflows: the AI generates the interpretation, the physician reviews and agrees, but the documentation doesn't explicitly record the physician's independent clinical assessment. The result is a claim that payers are flagging as unsupported by physician work — and potentially recouping on audit.
Practices implementing AI-assisted neurology diagnostics need documentation templates that explicitly capture physician review, amendment, and final clinical decision as separate from the AI output.
6. Tele-Neurology Has Permanent Reimbursement — But Billing Complexity Hasn't Simplified
The telehealth landscape for neurology has stabilized considerably compared to the uncertainty of the pandemic era. Tele-neurology is recognized as a legitimate and reimbursable delivery model for most neurology encounter types.
But the billing complexity of tele-neurology remains high. Modifier 95 vs. Modifier 93 for audio-video vs. audio-only. POS 02 vs. POS 10 based on where the patient is located. RPM management code documentation requirements that differ from in-person chronic disease management. The 2026 temporary telehealth code deletions for audio-only visits requiring updated coding approaches.
Telehealth claim denials in neurology often stem from incorrect codes, missing modifiers, or documentation errors. Each error has a different consequence — some result in denials, some result in systematic underpayment (claim processes as in-person when it was telehealth), and some create compliance exposure for billing incorrectly for otherwise legitimate services.
The practices executing tele-neurology billing correctly have built it as a distinct billing pathway with specific validation rules — not an extension of in-person billing logic applied to video visits.
7. The Workforce Shortage Is Amplifying Every RCM Risk
The U.S. government projects a 19% shortage in the neurology workforce by 2025 — a projection that, based on historical patterns, likely underestimated the actual shortfall. Over 60% of denied neurology claims are never resubmitted due to staffing shortages, lack of follow-up systems, or poor visibility.
When practices are operating at maximum clinical capacity with constrained administrative staff, billing quality suffers predictably: documentation is rushed, coding review is cursory, and follow-up on denied claims is deprioritized. Neurology's billing complexity — LCD compliance, modifier rules, ICD-10 specificity — requires specialized knowledge that takes months to develop and walks out the door with every biller who leaves.
The practices insulating themselves from this fragility are those that have automated the rules-based execution layer — so that coding accuracy doesn't depend on any individual's knowledge or any day's staff bandwidth. The clinical expertise of neurology's workforce is irreplaceable. The billing rules that govern that expertise should run on systems that never forget them.
The Pattern Across All Seven
Every trend on this list creates pressure in the same direction: more diagnostic complexity, more payer scrutiny, more documentation requirements, and less tolerance for the billing inconsistencies that manual execution inevitably produces.
The neurology practices outperforming financially in 2026 share one characteristic: their revenue cycles execute precisely — ICD-10 validation, EEG/EMG coding, chemodenervation billing, PA lifecycle management — so that clinical volume translates to financial performance.
