Neurology & Neuro-Diagnostic Billing Integrity Diagnostic
Eliminate automated unbundling write-offs on electrodiagnostic EMG studies (CPT 95886/95907), recover chronic migraine onabotulinumtoxinA denials (CPT 64615 with J0585), and optimize in-office infusion suites.
Neurology practices operate complex clinical centers combining cognitive consultations, electrodiagnostic laboratories (EMG/NCS), and high-margin ambulatory infusion suites (Ocrevus, Tysabri, Vyvgart). Payers aggressively audit nerve conduction studies (NCS CPT 95907-95913), demanding detailed proof of the number of nerves tested and requiring simultaneous needle EMG documentation. Our forensic neurology audit ensures strict adherence to American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) guidelines and protects high-dollar biologic infusion margins.
Audit red flags
- Commercial carriers rejecting CPT 95911 claiming excessive number of nerves tested for carpal tunnel syndrome.
- Botox for chronic migraine denied because the clinical chart omitted documentation of previous failed prophylactic medications (topiramate, beta blockers).
- Infusion administration codes (CPT 96413) downcoded to therapeutic hydration (CPT 96360).
- Extended video EEG monitoring (CPT 95700 series) rejected due to technical component unbundling edits.
Audit action plan
- 1. Electrodiagnostic Nerve Protocol Standardization — Ensure all EMG reports generate an automated summary table listing each sensory and motor nerve tested to support high-tier codes (95911/95912).
- 2. Migraine Prophylaxis Step-Therapy Defense — Audit headache consult records to ensure explicit documentation of 15+ headache days per month and failed oral trials prior to Botox.
- 3. Infusion Time-Tracking Flowsheet Verification — Audit nursing flowsheets to ensure exact pump start and stop times are documented to capture sequential infusion hours (CPT 96415).
Codes reviewed
- 95910 / 95911 — Nerve Conduction Studies (7-8 Nerves / 9-10 Nerves)
- 95886 — Needle Electromyography (Complete Limb)
- 64615 / J0585 — Chemodenervation for Chronic Migraine (Botox 200 Units)
- 96413 / 96415 — Chemotherapy / Biologic Infusion Administration
Frequently asked questions
How many nerves must be documented to bill CPT 95911?
CPT 95911 requires testing and documentation of 9 or 10 separate nerves. Each motor nerve, sensory nerve, and F-wave study counts toward this total under AANEM guidelines.
Why do payers audit Botox wastage for chronic migraine?
Botox is packaged in 100-unit and 200-unit single-dose vials. The standard chronic migraine protocol utilizes 155 units. Practices must bill 155 units under J0585 and 45 units under J0585 with Modifier JW to receive reimbursement for the discarded drug.
