What Neurology Practices Must Know About 2026 Billing Changes

If your neurology practice has not reviewed its billing workflows against the 2026 Medicare Physician Fee Schedule, there is a real chance your team is submitting claims under criteria that no longer apply. Every January brings a round of CPT revisions, relative value unit (RVU) adjustments, and policy changes that affect how neurology services are documented and reimbursed. In 2026, several of those changes hit areas that neurology practices rely on heavily: evaluation and management services, high-cost drug administration, and the evolving telehealth coverage rules that many practices built significant patient volume around.

 

The practices that catch these changes early update their EHR templates, retrain their billing teams, and submit clean claims from day one of the new year. The practices that miss them spend the first quarter managing denials that should never have happened. This blog covers what changed, what it means for your revenue cycle, and what neurology-specific billing infrastructure looks like when it is built to handle these transitions without disruption.

 

The 2026 Physician Fee Schedule and What Changed for Neurology

 

The Centers for Medicare and Medicaid Services (CMS) finalizes the Medicare Physician Fee Schedule (MPFS) each November for the following calendar year. The 2026 final rule carried adjustments to the conversion factor alongside targeted changes to the code sets and documentation requirements that directly affect neurology practice billing.

 

Neurology is a specialty with significant exposure to changes in E/M valuation because cognitive services represent a large share of the typical neurology visit. Prolonged services codes, which allow practices to report additional time beyond the base E/M thresholds, have been a consistent area of payer scrutiny. The 2026 rules clarified time documentation requirements for these codes in ways that neurology practices billing complex Alzheimer's, epilepsy, and multiple sclerosis visits need to understand and implement in their documentation templates.

 

Separately, the American Medical Association (AMA) released CPT code revisions effective January 2026 that affect how several neurology-specific services are reported, including changes to electroencephalography (EEG) coding and updates to the nerve conduction study code family. Practices that did not update their charge capture systems before January 1 may be submitting codes that no longer map to current CPT descriptors, a problem that generates both denials and compliance risk.

 

High-Cost Drug Administration: Where Revenue Leakage Starts

 

Neurology is one of the highest-stakes specialties for drug administration billing. Infusion therapies for multiple sclerosis, myasthenia gravis, Parkinson's disease, and migraine prevention represent significant revenue lines for neurology practices with infusion capacity. They also represent some of the most complex billing scenarios in the outpatient setting.

 

The American Academy of Neurology (AAN) has consistently flagged drug administration coding as an area where neurology practices face disproportionate denial and underpayment exposure. The primary sources of error are not random. They cluster predictably around a set of documentation and coding requirements that change with the annual HCPCS update and with payer-specific medical necessity criteria for high-cost neurological agents.

 

The billing requirements that most frequently drive denials and underpayments in neurology drug administration include the following. Each of these elements must be present in the clinical and billing record for a drug administration claim to survive payer review:

 

• Drug-specific prior authorization documentation: High-cost MS therapies, anti-CGRP migraine agents, and Alzheimer's disease treatments each carry payer-specific PA requirements. The authorization must match the exact drug, dose, and frequency documented in the clinical record and reflected on the claim.
• Sequential infusion code logic: When a patient receives multiple infused agents in a single encounter, the initial infusion code and the sequential or concurrent infusion codes must be applied in the correct order. Errors in sequencing are among the most common neurology infusion billing mistakes and generate systematic underpayment.
• Waste documentation for partial vials: When a high-cost biologic is administered and a portion of the vial is discarded, Medicare and most commercial payers allow billing for the discarded amount with appropriate modifier and documentation. Practices that do not capture waste consistently leave documented revenue on the table.
• J-code accuracy and NDC number requirements: Many payers require that drug claims include the National Drug Code (NDC) number alongside the HCPCS J-code. Missing NDC information is a growing source of automated denials that most general billing platforms do not catch at the claim level.
• Evaluation and management on infusion days: Billing a separately payable E/M service on a day when the patient also receives an infusion requires documentation that the E/M service was significant and separately identifiable from the administration service itself. Without that documentation, the E/M is bundled and the revenue is lost.

 

Telehealth Coverage for Neurology: What Remains and What Expired

 

The COVID-era telehealth flexibilities that allowed neurology practices to bill established patient visits, cognitive assessments, and remote monitoring services through expanded telehealth coverage have continued to evolve. The MGMA has tracked the impact of telehealth policy changes on specialty practice revenue closely, noting that neurology is among the specialties most affected by shifts in telehealth coverage because of its high proportion of patients with mobility limitations, cognitive impairment, and chronic neurological conditions that make in-person visits more burdensome.

 

For 2026, neurology practices need to confirm which telehealth services remain covered under permanent Medicare authority, which are covered under extended temporary authority, and which have reverted to in-person-only coverage. Billing telehealth services under a coverage category that has expired or changed generates denials that are difficult to recover because the service has already been rendered. The time to verify coverage is before the appointment is scheduled, not after the claim is submitted.

 

Practices with high telehealth volume should also confirm that their EHR and billing platform correctly applies the current place-of-service codes and telehealth modifiers for 2026. These designations changed at multiple points during the public health emergency period and have continued to evolve. An outdated modifier applied to a covered telehealth service can generate a denial just as effectively as billing for a service that is not covered at all.

 

How Specialty-Built Billing Infrastructure Absorbs These Changes

 

The practices that handle annual billing changes with the least disruption share one operational characteristic: their EHR and billing platform is updated before the new year, not after the denials arrive. That requires a vendor who tracks neurology-specific coding changes, pushes those updates into clinical templates and charge capture logic, and communicates what changed and why before the change takes effect.

 

A general-purpose EHR adapted for neurology does not provide that. It provides a platform that your billing team has to manually update, that your coders have to monitor independently, and that will not flag a sequential infusion sequencing error or a missing NDC number before the claim goes out. In a specialty where individual infusion claims can represent thousands of dollars in revenue, those errors are not minor.

 

ADS has supported neurology practices for decades as part of a broader specialty practice portfolio that now spans more than 30,000 physicians. The Medics Suite is built to accept annual CPT and HCPCS updates as part of the platform's regular release cycle, not as a manual process your team manages. Neurology-specific documentation templates, drug administration charge capture logic, and telehealth modifier management are part of the system, not workarounds built on top of it.

 

Park Avenue Medical Professionals, a long-term ADS client operating across multiple specialties in a demanding metropolitan market, has maintained a nearly 99% first-pass clean claim rate year over year. That rate does not happen by accident. It happens because the system is updated, the templates are correct, and the billing logic reflects current payer requirements before claims are submitted.

 

Since 1977, ADS has maintained a 98% client retention rate and an average client relationship of 15 years. Neurology practices that have been through multiple annual billing transitions with ADS do not spend January untangling denials. They spend it seeing patients.

 

Has your neurology practice confirmed that its EHR templates and billing logic reflect 2026 CPT, HCPCS, and MPFS changes? The ADS team works with neurology practices to identify where outdated coding, incomplete drug administration documentation, and telehealth billing gaps are costing revenue. A Revenue Health Review takes less time than your next prior authorization appeal.
