Neurology Billing as Focused as Your Diagnostics.

Neurology billing services combine high-complexity E/M coding, diagnostic testing with layered documentation requirements, and high-dollar infusion programs — each with denial patterns that generic billing teams miss repeatedly. One wrong EMG component code or a Botox prior auth lapse erases a significant chunk of monthly revenue.

In neurology, the gap between what you document and what you bill is where the most revenue disappears.

Neurologists consistently provide the most medically complex encounters in outpatient medicine — managing epilepsy, multiple sclerosis, Parkinson’s disease, dementia, and stroke — yet many neurology practices systematically undercode their E/M visits. Under the 2021 MDM guidelines, a Level 5 office visit (99215) requires high MDM: multiple chronic illnesses with severe exacerbation, drug therapy requiring intensive monitoring, or decisions regarding hospitalization. Most neurology follow-up visits for MS, epilepsy, or Parkinson’s qualify for Level 4 or Level 5 — but only when documentation reflects the full complexity of the encounter. At the same time, neurology’s diagnostic infrastructure (EEG, EMG/NCV, sleep studies, intraoperative monitoring) each carry their own billing rules, and MS and migraine infusion programs carry J-code precision requirements where one incorrect digit means a denied claim. Our full RCM services are built for this complexity.

EEG Billing: Routine, Ambulatory, and Long-Term Monitoring

Routine EEG codes range from 95816 (routine EEG, awake and drowsy) to 95822 (EEG during sleep). Ambulatory EEG monitoring uses codes 95951 (monitoring for up to 12 hours) through 95953 (monitoring for more than 12 hours). Long-term epilepsy monitoring unit (EMU) codes 95711–95720 cover video-EEG monitoring for seizure characterization and surgical candidacy evaluation — a high-value service that requires documentation of the medical indication and the physician's review time. Each EEG type has distinct medical necessity criteria, and billing the wrong level of monitoring generates both a denial and a potential overpayment audit.

EMG and Nerve Conduction Studies

Electromyography (EMG) and nerve conduction velocity (NCV) studies are among the most frequently miscoded services in neurology. EMG codes 95885–95887 (limited, one extremity) and 95908–95913 (NCV studies by number of conductions performed) must match the specific muscles and nerves tested — and the documentation must list each muscle examined by name. When a physician performs both the EMG and NCV in the same session, both sets of codes apply. When a technician performs the NCV and the physician interprets it, modifier -26 applies to the interpretation. Billing a global NCV code when only the professional component was provided is both an overpayment and a compliance risk.

Botox for Migraine: 31 Injection Sites, One Protocol

FDA-approved onabotulinumtoxinA (Botox) for chronic migraine is billed using CPT codes 64612–64616 for the injection procedure and J0585 for the drug (per unit). The approved protocol — 155 units across 31 injection sites in seven head and neck muscle groups — must be documented in detail. Prior authorization is required by virtually all commercial payers and most Medicare Advantage plans, and many require documented failure of two or more preventive oral medications before approving Botox. Practices that don't manage the PA lifecycle consistently have their highest-volume migraine revenue interrupted by auth lapses between treatment cycles.

MS Infusion Billing: J-Code Precision

Multiple sclerosis infusion therapy is a significant revenue stream for neurology practices with in-office infusion suites. Natalizumab (Tysabri) is J2323; ocrelizumab (Ocrevus) is J2350; glatiramer acetate (Copaxone) is J1595. Infusion administration codes 96413 (first hour) and 96415 (each additional hour) accompany the J-code on every claim. Prior authorization must be active before every infusion — MS biologics are among the highest prior auth burden medications in neurology, with some payers requiring re-authorization every 6 months. A single prior auth lapse cancels the infusion revenue for that cycle.

Happy Billing Benchmarks for Neurology:

98% Clean Claim Rate

Neurology claims fail most often on EMG component-muscle documentation mismatches, Botox prior auth lapses, and incorrect EEG level selection. We catch all three before the claim leaves our system.

E/M Level Optimization

We review your E/M distribution monthly and compare it against the documented complexity of your neurology patient panel. Level 4 and Level 5 visits that were coded at Level 3 are identified and corrected through documentation guidance — not just billing fixes.

Infusion Prior Auth Lifecycle Management

Every infusion patient’s authorization is tracked from initial approval through renewal — with alerts before any auth expires. No infusion revenue is lost to a preventable auth lapse.

A/R Under 35 Days

Neurology practices manage a mix of high-volume diagnostic testing, monthly infusion cycles, and complex E/M billing. Our 24/7 team keeps all three revenue streams moving simultaneously.

Our Specialized Process

EEG and EMG Code Accuracy

We match EEG codes to the documented monitoring type and duration, and EMG/NCV codes to the specific muscles and nerves tested — with physician vs. technician component billing applied correctly. No diagnostic testing revenue is lost to wrong-level codes or component billing errors.

Botox Migraine Protocol Management

We manage the full prior authorization cycle for Botox migraine treatment — including step therapy documentation, auth submissions, cycle tracking, and re-authorization before the 12-week interval. Revenue from your highest-volume migraine treatment stays uninterrupted.

MS Infusion Program Revenue Management

We handle J-code selection, infusion time coding, prior authorization, and waste documentation for every MS infusion — Tysabri, Ocrevus, and others. In-office infusion programs stay financially viable, not just clinically excellent.

High-Complexity E/M Documentation Support

We review E/M level distribution monthly and provide documentation guidance when patient complexity outpaces billing patterns. The chronic-condition complexity of neurology patients is captured at Level 4 and Level 5 — not systematically underbilled at Level 3.

Frequently Asked Questins

How do you handle billing for in-office infusions like Tysabri or Ocrevus?

We manage the complete infusion billing workflow: prior authorization by drug and payer, J-code selection (J2323 for Tysabri, J2350 for Ocrevus), infusion time coding (96413 + 96415), waste documentation, and patient cost-sharing calculation. For MS biologics specifically, we track re-authorization cycles and submit renewal requests before any authorization expires — preventing the infusion cancellations that create both revenue loss and patient care disruption.

What are the documentation requirements for billing Level 4 and Level 5 neurology E/M visits?

Can you manage the prior authorization process for Botox migraine treatments?

How do you handle EMG and nerve conduction study billing when a technician performs part of the study?

Do you handle billing for neuropsychological testing?

Is your Neurology revenue losing its nerve?

From EEG interpretation to MS infusion cycles to Botox authorization management, every service your neurology team provides deserves accurate, timely reimbursement.
