Neurology Billing Services
Botox for chronic migraine pays through a dual claim — CPT 64615 (chemodenervation of muscles innervated by facial, trigeminal, cervical spinal and accessory nerves) at roughly $200 plus J0585 (onabotulinumtoxinA) at approximately $6 per unit for the 155–195 units a typical migraine protocol delivers — and Medicare denies the entire encounter when the chronic migraine qualification documentation does not show 15+ headache days per month for 3+ months and failed trials of 2+ preventive medications. Neurology billing concentrates in three high-revenue lines: neurodiagnostic testing (EEG 95812–95830, EMG 95860–95913, evoked potentials 95925–95938, polysomnography 95805–95811), buy-and-bill biologic infusions for multiple sclerosis and migraine (Tysabri, Ocrevus, Vyepti), and complex office E/M with prolonged services on the 99417/G2212 add-on family. Long-term EEG monitoring under codes 95720, 95722, and 95724 carries per-day billing for inpatient video EEG used in epilepsy evaluation; the technical-and-professional component split applies on every diagnostic study, with modifier 26 for the interpretation when the technical component is at a separate facility. Add NIH Stroke Scale documentation for tPA encounters, the AANEM-defined limits on the number of nerve conduction studies per session that CMS LCDs enforce, and prior authorization through imaging-management vendors (eviCore, AIM, National Imaging Associates) for advanced neuroimaging including MRI and PET, and neurology becomes one of the most diagnostic-heavy billing environments in outpatient medicine.

Common Billing Friction in Neurology
Botox J0585 unit billing and chronic migraine qualification documentation
Botox for chronic migraine is billed as CPT 64615 (chemodenervation of head and neck muscles, PREEMPT protocol) plus J0585 onabotulinumtoxinA per unit administered. Medicare and most commercial payers require documentation of chronic migraine ICD-10 (G43.711, G43.719) supported by a headache diary showing 15+ days per month for 3+ months, failed trials of at least two preventive medications, and a neurologist or headache-specialist attestation. Drug waste from single-use vials must be billed with modifier JW. Cigna and several BCBS plans add their own re-authorization at every 12-week injection cycle, and missed diary documentation between cycles produces denials that compound across patient panels.
EMG/NCS bundling under AANEM guidelines and same-day NCS+EMG denials
Nerve conduction studies (95907 1–2 studies, 95908 3–4, 95909 5–6, 95910 7–8, 95911 9–10, 95912 11–12, 95913 13+) bill per nerve count and pair with needle EMG (95885 limited per extremity, 95886 complete per extremity). Aetna applies a multiple-procedure reduction when NCS and EMG are billed on the same day, treating them as bundled even when both are clinically necessary for a single diagnosis. The unbundle requires distinct-clinical-indication documentation and appeal under the AANEM joint AANEM/AAN guidelines that explicitly support same-session NCS and EMG for many diagnoses including carpal tunnel and radiculopathy.
Long-term video EEG (95720, 95722, 95724) and the per-day inpatient billing rule
Long-term EEG monitoring for epilepsy diagnosis and pre-surgical evaluation bills per day of monitoring under codes 95720 (≤12 hours), 95722 (>12 hours each subsequent day, intermittent monitoring), 95724 (>12 hours continuous monitoring), with 95717 and 95718 covering the technical recording component. Video EEG adds another layer with the simultaneous video recording requirement. UnitedHealthcare requires prior authorization for all EEG including routine, and denies retroactively when authorization is not obtained before the test date — a pattern that hits epilepsy monitoring units particularly hard when authorization paperwork lags admission.
MS biologic infusion buy-and-bill (Tysabri, Ocrevus, Vyepti) with frequency-edit drift
Multiple sclerosis disease-modifying therapy runs through buy-and-bill biologics: natalizumab/Tysabri J2323 every 4 weeks, ocrelizumab/Ocrevus J2350 every 6 months, eptinezumab/Vyepti J3032 every 3 months for migraine prevention. Each pairs with infusion administration codes 96365 (initial up to 1 hour) and 96366 (each additional hour). Cigna applies frequency edits on neurology infusions that differ from FDA-approved dosing schedules; a Tysabri infusion 26 days after the prior infusion can deny under Cigna's edit even though clinically appropriate. Medical exception requests with supporting literature are required to clear the edit, adding 7–14 days to payment.
Prolonged service capture (99417, G2212) and the Medicare-versus-CPT divergence
Complex neurology office visits routinely run 60–90 minutes for new patients with multi-system disease (MS evaluation, dementia workup, refractory epilepsy). The post-2021 office E/M revisions consolidated prolonged service codes — CPT 99417 attaches to 99205 or 99215 in 15-minute increments above the maximum E/M time, while Medicare uses HCPCS G2212 with slightly different time-trigger thresholds. Practices that level the visit to 99215 without billing prolonged services forfeit roughly $30–$40 per 15-minute increment of additional documented time. Across a neurologist's panel, unbilled prolonged service codes typically represent $40,000–$60,000 of annual recoverable revenue.
Neurology-Specific Payer Issues We Watch For
UnitedHealthcare
Issue: Requires prior authorization for all EEG studies including routine EEGs, and denies claims retroactively when auth is not obtained before the test date
Our approach: We submit EEG prior authorization requests at the time of ordering and track authorization status before the scheduled test date to prevent retroactive denials
Aetna
Issue: Bundles nerve conduction studies (95907-95913) with EMG (95885-95886) when performed on the same day, applying a multiple procedure reduction that significantly lowers reimbursement
Our approach: We document distinct clinical indications for NCS and EMG components and appeal inappropriate bundling when both tests are medically necessary for the diagnosis
Medicare
Issue: Botox for chronic migraine (J0585) requires documentation of 15+ headache days per month for 3+ months and failure of 2+ preventive medications before coverage
Our approach: We compile chronic migraine qualification documentation including headache diary data, failed medication history, and specialist attestation before submitting Botox claims
Cigna
Issue: Applies frequency limits on neurology infusion therapies (Tysabri, Ocrevus) that differ from the FDA-approved dosing schedule, denying claims that follow standard medical protocols
Our approach: We track Cigna-specific infusion frequency limits per drug and submit medical exception requests with supporting literature when the FDA schedule differs from the payer policy
What We Handle
EEG coding (95812–95830) and long-term video EEG (95720, 95722, 95724)
Routine EEG, sleep-recording 95819, awake-and-asleep 95816, and inpatient long-term video EEG per-day billing. Technical and professional component split with modifier 26 where the interpretation is at a separate location.
EMG and NCS billing (95860–95913, 95885–95886) per AANEM guidelines
Nerve conduction study count-based coding (95907 1–2 through 95913 13+ studies), needle EMG limited and complete per extremity, with distinct-clinical-indication documentation to clear Aetna and similar same-day bundling edits.
Botox 64615+J0585 chronic migraine billing with PREEMPT protocol documentation
Chronic migraine qualification packaging including headache diary, failed-medication history, and specialist attestation. JW drug-waste capture, 12-week re-authorization tracking, and Cigna re-auth scheduling between injection cycles.
MS and migraine infusion buy-and-bill (J2323, J2350, J3032) with frequency-edit defense
Tysabri, Ocrevus, and Vyepti J-code billing paired with 96365/96366 infusion administration. Cigna and Aetna frequency-edit medical exception submissions when FDA-approved dosing differs from payer policy.
Advanced neuroimaging prior auth through eviCore, AIM, and NIA
Brain MRI, MRA, CT, and PET prior authorization through imaging-management vendors with neurological exam findings, prior imaging results, and symptom history packaged to vendor approval criteria.
Prolonged service capture on 99417 (CPT) and G2212 (Medicare)
Time-documented prolonged service add-on billing on 99205 and 99215 visits that exceed the maximum E/M time threshold. CPT 99417 versus HCPCS G2212 routing per payer with 15-minute-increment time tracking.

Real Results
The Challenge
A 5-provider neurology practice was losing revenue on EEG/EMG professional component billing, had no system for capturing prolonged service codes on complex visits, and was underbilling infusion therapy administration
Our Approach
We implemented diagnostic testing component billing review, introduced prolonged service code tracking for visits exceeding standard time thresholds, and corrected infusion therapy time-based add-on coding
Key Outcomes
- check_circle EEG/EMG professional component revenue increased 28%
- check_circle Prolonged service codes added $4,200 per month in new revenue
- check_circle Infusion administration billing corrected — average increase of $85 per infusion session
- check_circle Annual practice revenue increased by $234K
“Our prolonged service revenue was zero before MedPrecision. Now it is $50,000 per year from visits we were already doing — we just were not billing for the extra time.”
Why General Billing Teams Miss Neurology Issues
General billing staff handle dozens of specialties and rarely develop the depth needed for neurology coding nuances. Here is what gets missed.
Modifier and bundling errors
Specialty-specific modifier rules and CCI edits are frequently overlooked by teams that do not work exclusively in neurology.
Under-coding high-complexity visits
Neurology encounters often qualify for higher-level E/M codes, but generalist billers default to mid-level codes to avoid audit risk.
Missed payer-specific rules
Each payer has unique coverage and documentation requirements for neurology procedures that general teams rarely memorize.
Slow denial turnaround
Without specialty knowledge, appeal letters lack the clinical specificity needed to overturn neurology denials quickly.
“Neurology practices with diagnostic testing suites are sitting on significant untapped revenue from professional component billing and prolonged service codes. Most practices bill the test but undervalue the interpretation and extended visit time.”

Neurology Billing Terms
- Professional Component (26)
- The physician's interpretation and report for a diagnostic test. In neurology, applies to EEG readings, EMG interpretations, and nerve conduction study analysis. Billed with modifier 26 when the technical component is performed at a separate facility.
- Technical Component (TC)
- The equipment, supplies, and technician cost portion of a diagnostic test. In neurology, covers EEG electrode placement and recording, EMG equipment, and nerve conduction testing apparatus. Billed with modifier TC.
- Prolonged Service Codes
- CPT codes (99354-99357) billed when physician face-to-face time exceeds the typical time for an E/M visit by 30+ minutes. Common in neurology for complex diagnostic consultations and treatment plan modifications.
- Nerve Conduction Study (NCS)
- Electrodiagnostic test measuring nerve signal speed and strength. Coded based on the number of nerves tested (95907-95913). Must be documented with specific nerve names, stimulation sites, and recording sites.
- Electromyography (EMG)
- Needle electrode testing of muscle electrical activity to diagnose neuromuscular disorders. Coded per extremity (95885-95886) with documentation of specific muscles tested and findings for each.
- Buy-and-Bill Infusion
- A model where the neurology practice purchases biologic drugs (Tysabri, Ocrevus, Botox), administers them, and bills the payer for both the drug (J-code) and the administration (96365-96368). Requires inventory management and drug waste documentation.

Request Review arrow_forwardHow do you bill for Botox injections for migraine?
We bill Botox for chronic migraine using CPT 64615 for chemodenervation of the head and neck muscles, plus J-code J0585 for the Botox units administered. Documentation must include the chronic migraine diagnosis, number of units injected per site, and prior treatment history to support medical necessity.
What are the limits on EMG/nerve conduction studies per session?
Most payers follow the AANEM guidelines allowing up to 4 nerve conduction studies and EMG of related muscles per session. Medicare and some commercial payers have specific LCD policies limiting studies based on the clinical indication. We code within these limits while increasing the studies documented.
Do you handle prior authorization for neurological imaging?
Yes. We submit prior authorizations through imaging management programs like eviCore, AIM, and National Imaging Associates with clinical documentation including neurological exam findings, symptom history, and prior imaging results to meet approval criteria.
