Neurology Medical Billing Services for Practices

“We take care of you, so you can take care of your patients.” For more than three decades, AMS Solutions has handled medical billing for neurology and neurosurgery practices across the United States. We’re U.S.-based, in-house, AAPC-certified, and HIPAA-compliant — and we know neurology coding inside and out, from EMG/NCS pro-tech splits to chronic migraine injection to neurology’s notoriously high denial rate (35% initial, 14-18% chronic, the highest of any specialty). This page walks through how AMS handles neurology billing, the procedures and modifiers we work with daily, and what to expect when you partner with us.

A Bespoke Team for Your Neurology Practice

Every AMS client is assigned a dedicated billing team led by an Account Manager you can reach directly — no overseas call centers, no phone trees, no handoffs between strangers. Your team is built specifically for neurology coding nuances and the EMR/EHR you already use (Epic, NextGen, eClinicalWorks, athenahealth, and others).

• Account Manager — your single point of contact, hands-on with daily RCM, charge capture, rejection resolution, and denial work.
• Billing Specialists — focused on neurology-specific claim submission, payer rules, and modifier accuracy.
• Director of Operations — workflow design, SOP development, audit.
• Credentialing Team — provider enrollment, hospital privileges, payer maintenance.

Neurology Billing Expertise

Neurology has the highest claim denial rate of any specialty — 35% initial, 14–18% chronic. The reasons are structural: pro/tech component splits on EMG and EEG, dense modifier rules around E&M-with-procedure bundling, payer-specific prior authorization on chronic migraine injections and infusion drugs, and ongoing LCD compliance pressure. We have specific operational depth in each.

EMG & Nerve Conduction Studies (NCS)

EMG/NCS is the highest-volume neurology procedure, and the professional vs. technical component split (modifier -26 and -TC) is where most claims get denied. Key codes we work daily:

• CPT 95907–95913 — Nerve conduction studies (1–2, 3–4, 5–6, 7–8, 9–10, 11–12, 13+ studies).
• CPT 95860–95887 — Needle EMG (single muscle through 5+ extremities).
• Modifier -26 vs -TC — Required when the physician interprets but the facility owns the equipment, or vice versa. Wrong split = automatic denial.
• NCD/LCD compliance — Medicare requires medical necessity documentation that maps cleanly to the diagnosis code; we audit this on every claim.

Electroencephalography (EEG)

Long-term and ambulatory EEG monitoring has expanded under newer CPT codes, and payers are aggressive about technical-component documentation:

• CPT 95812–95819 — Routine EEG (40-60 minutes, 41+ minutes, extended).
• CPT 95700–95726 — Long-term EEG monitoring (the 2020 code overhaul replaced 95950-95957 with technical-vs-professional bundles by duration).
• CPT 95961–95962 — Functional brain mapping (rare but high-reimbursement).

Chronic Migraine Injections

OnabotulinumtoxinA for chronic migraine is one of the most denial-prone procedures in neurology because of (1) PA requirements with payer-specific clinical criteria, (2) the J-code drug bill that often gets miscoded as the procedure code, and (3) the strict 12-week interval requirement:

• CPT 64615 — Chemodenervation of muscle(s) for chronic migraine.
• HCPCS J0585 — OnabotulinumtoxinA drug units (billed separately from the procedure).
• Prior auth — Almost universally required; failed step-therapy is the #1 denial reason.

Neurology Infusion Therapy

IVIG, anti-CD20 monoclonal antibodies, natalizumab,, and other infused biologics for MS, myasthenia gravis, and CIDP carry both high reimbursement and high denial risk. We handle:

• CPT 96365–96368 — Infusion administration (first hour, additional hours, sequential).
• J-codes — Drug-specific billing with unit conversion (mg, mcg, vial).
• PA + buy-and-bill vs. specialty-pharmacy split — Different payers route the same drug differently; we track per-payer rules.

Prior Authorization — The #1 Neurology Denial Driver

Neurology PAs cover OnabotulinumtoxinA, infusions, advanced imaging (MRI brain with contrast, MRI spine), implanted devices (DBS, VNS, RNS), and selected EMG/NCS combinations. We submit and track PAs as part of the same workflow that submits the claim — not as an afterthought — with payer-specific submission rules we update each quarter.

Neurology Modifiers That Get Missed

• Modifier -25 — Significant E&M same day as a procedure (common with new patient consults that lead to in-office injections).
• Modifier -26 / -TC — Professional vs. technical component split for EMG, EEG, and imaging interpretation.
• Modifier -59 / X{EPSU} — Distinct procedural service for bilateral nerve conduction or staged procedures.
• Modifier -51 vs -59 — Multiple procedures vs. distinct procedural service — getting this wrong drives bundling denials.

A Proven Process

• Claims submitted within 24 hours of creation.
• Checked, scrubbed, and submitted daily.
• Denials and rejections handled immediately.
• ERAs/EOBs posted upon receipt.
• Monthly custom financial health report with payer-mix and denial-category breakdowns.
• Regular meetings to refine workflows.

Security & Compliance

• HIPAA compliant. Every client practice signs a Business Associate Agreement (BAA). Safeguards meet HIPAA requirements.
• Secure systems. Encrypted data and secure networks for every workflow involving patient information.
• Role-based access. Sensitive information is controlled, audit-logged, and limited to team members who need it.
• AAPC-certified staff. Our billers and coders hold AAPC credentials (CPC, CPB), with neurology-specific continuing education as AAN guidelines, CMS LCDs, and payer policies evolve.

How Even a Small Improvement Makes a Big Difference

A neurology practice with $250,000 in monthly collections and a 14% chronic denial rate is leaving roughly $35,000 on the table every month. Cut that denial rate to 7% — realistic when EMG/NCS modifier splits are enforced, OnabotulinumtoxinA PAs are tracked alongside the procedure, and infusion J-code units are reconciled to the drug ordered — and you recover roughly $17,500 a month. That’s $210,000 a year in revenue that was already yours. Example for illustration purposes only. Actual results vary by specialty, payer mix, volume, workflow, and current billing performance.

Frequently Asked Questions

What neurology CPT codes does AMS handle?

We work the full neurology code set every day — including EMG/NCS 95860-95913, EEG 95812-95830, sleep studies 95805-95811, evoked potentials 95925-95930, autonomic function testing 95921-95924, lumbar puncture 62270, and the chronic migraine injection J0585 injections (64615) family. Our coders know which procedures bundle, which modifiers are required, and how each payer handles pro/tech splits.

How do you handle EMG/NCS billing and the professional/technical split?

EMG and nerve conduction studies routinely split between professional (modifier 26) and technical (TC) components, and the rules differ by place of service and equipment ownership. We track who’s reading the study, who owns the equipment, and bill professional vs. global vs. technical accordingly. We also ensure the correct CPT pairing — e.g. 95910 vs. 95911 vs. 95912 based on nerve count — because miscoding this is one of the most common sources of neurology underpayment.

Can you handle chronic migraine injection (J0585) billing?

Yes. Chronic migraine OnabotulinumtoxinA is one of the most prior-auth-intensive billable services in neurology. We handle the J0585 unit dosing (typically 155-195 units), the 64615 administration code, the required prior auth and step therapy documentation, and the 12-week re-auth cycle. We also track and recover NDC pricing and J&J/AbbVie copay assistance where applicable.

How does AMS handle neurology prior authorizations?

Neurology has one of the highest prior auth burdens in medicine — OnabotulinumtoxinA, MRI/MRA, IVIG, monoclonal antibodies for migraine (CGRP), and many EP and sleep studies require auth. We track each payer’s requirements, file the request with supporting clinical, follow up until you have a number, and confirm the auth is attached to the claim before submission. Missed auths drive roughly 15-18% of neurology denials when not actively managed.

How do you handle neurology denials and the 35% initial denial rate?

Neurology has the highest initial denial rate of any specialty (35% initial, 18% chronic). Denials are worked the day they hit your aging, not weekly. We root-cause each denial — auth, eligibility, LCD/NCD policy, modifier, documentation — appeal the winnable ones, and report trends back monthly so the same denial pattern stops repeating. Most clients see their denial rate drop materially within 90 days.

How long does neurology billing onboarding take?

Most neurology clients are fully onboarded inside 2-4 weeks. We handle the EHR/PM integration (Epic, NextGen, eClinicalWorks, athenahealth, and others), payer setup, fee schedule load, and provider enrollment review. Your practice keeps seeing patients without disruption during the transition.
