Neurology billing spans complex diagnostic procedures, high-cost drug administration, and chronic disease management — each with unique coding rules and payer requirements that drive a specialty-average denial rate above 13%. We know every code, every modifier, every prior auth rule.
Common Billing Challenges
These are the billing failure points we see most often in neurology practices — and the ones our team resolves systematically from day one.
Routine vs. extended EEG billing requires correct selection among 95812, 95813, 95816, 95819, 95822 based on duration and awake/sleep state. Wrong code selection is the most common neurology coding error.
Nerve conduction studies (95907-95913) and needle EMG (95860-95872) must be billed separately with correct component counts. Payers apply automatic edits to catch unbundling and unit overuse — legitimate complex studies are often caught incorrectly.
Botox for migraine (J0585), spasticity, and cervical dystonia requires prior authorization with specific diagnosis codes, failed first-line treatment documentation, and dosage justification. Approval rates average 74% on first submission without specialist preparation.
IV immunoglobulin (J1561), natalizumab (J2323), and other infusion drugs require accurate J-code billing with units matching the exact administered dose. Drug wastage documentation and NDC number reporting are required by major payers.
HCPCS codes for attended PSG (95810), unattended (95806), and titration studies must reflect the actual type performed. Home sleep testing (HCPCS G0398/G0399) has different rules than facility-based studies.
Neurology patients with epilepsy, MS, or Parkinson's frequently qualify for 99215/99215 based on multiple chronic conditions — but only with MDM documentation of moderate-high complexity. Systematic undercoding is common.
Key Procedure Codes
Our coders hold specialty-specific credentials and train continuously on the codes that drive the most revenue — and the most denials — in neurology.
| CPT Code | Description | Common Issue |
|---|---|---|
| 95816 | EEG awake and drowsy | Duration and awake/sleep state determine code selection |
| 95907 | Nerve conduction, 1-2 studies | Component billing with needle EMG; payer edit rules |
| 95869 | Needle EMG, specific muscles | Combination with NCS requires modifier review |
| J0585 | OnabotulinumtoxinA injection | Prior auth required; units = per 100 units administered |
| 95810 | Polysomnography, attended | Titration (95811) is a separate code — can't bundle |
| 99215 | Office visit, high complexity | MS/epilepsy MDM often supports this level |
Why Rcmaxis
We're not a generalist billing service that added a specialty module. Our team is built around specialty-specific expertise.
Our coders hold CNEEG and CNCT credentials specific to neurophysiology billing — not generic CPC coders applying neurology codes without specialty training.
We manage the full prior auth workflow for botulinum toxin — including failed first-line documentation packages that increase first-pass approval rates by 35%.
J-code billing for neurological infusion drugs includes NDC reporting, wastage documentation, and dose-matched unit calculations for every administered drug.
We maintain a current library of facility vs. home sleep testing billing rules for all major payers and Medicare LCDs.
For multiple sclerosis infusion programs, we manage the full drug-plus-administration billing workflow including prior auth cycles.
Quarterly coding audits identify neurology E/M undercoding — the highest-value per-visit correction in any specialty.
Straight answers to what practices usually ask before they switch.
Free revenue assessment for qualified practices. We audit your last 90 days of claims, identify every revenue leak, and show you a clear path to better collections — at no cost.
