Quick answer

AMS Solutions provides neurology medical billing services for independent neurology practices and groups: EEG and long-term EEG monitoring, EMG and nerve conduction studies, Botox for chronic migraine, infusions and E/M, with prior authorization and denial follow-up.

Neurology Medical Billing Services

“We take care of you, so you can take care of your patients.” Since 1992, AMS Solutions has handled medical billing for neurology and neurosurgery practices across the United States. We’re a dedicated team with AAPC-certified coders, and we sign a BAA for covered services. We know neurology coding inside and out, from EMG and nerve conduction study professional and technical splits to chronic migraine chemodenervation and infusion drug units. This page walks through how AMS handles neurology billing and revenue cycle management services, the procedures and modifiers we work with daily, and what to expect when you partner with us. Practices in specific states can also see our pages for neurology medical billing in California and neurology medical billing in New York.

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 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 claims are denial-prone for structural reasons: 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 (for a deeper walkthrough, see our EMG and EEG billing guide):

  • Nerve conduction studies: the nerve conduction study codes, selected by the number of studies performed, from one or two studies up through thirteen or more.
  • Needle EMG: the needle electromyography codes, from a single muscle study through studies covering multiple 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:

  • Routine EEG: the routine electroencephalography codes, selected by recording duration.
  • Long-term EEG monitoring: the long-term EEG monitoring code family introduced in the 2020 code overhaul, which replaced the earlier long-term monitoring codes with technical and professional bundles selected by duration.
  • Functional brain mapping: the cortical and subcortical stimulation mapping codes (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, billed per unit (1 billing unit = 1 unit of drug), separately from the procedure. 64615 is inherently bilateral, so it is reported once per session.
  • Prior auth: Almost universally required; missing step-therapy documentation is a common denial reason.
  • Full rules: Botox for chronic migraine billing (64615 and J0585).

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:

  • Infusion administration: the intravenous infusion administration codes for the initial hour, each additional hour, and additional sequential or concurrent infusions.
  • 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 for Neurology Services

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.

Sleep Medicine Billing

Many neurology practices also run sleep diagnostics, and those claims follow their own coverage, documentation and prior authorization rules. In-lab polysomnography, titration studies and home sleep testing each carry separate professional and technical component considerations, and a combined neurology and sleep visit needs documentation that supports every service billed. We run sleep claims as a distinct workflow alongside neurology, so the component split, the referring order and the authorization are in place before the claim goes out.

CPT codes 95800, 95801 and 95806 are deleted effective 1 January 2027 and remain valid through 31 December 2026. See our guide to the 2027 home sleep test code changes, or learn more about our sleep medicine billing services.

Neurology Coding, Documentation and Payment Details

EMG and NCV: the add-on rule that trips up most practices

The codes that cause the most trouble are the needle EMG add-on codes. 95885 (limited study), 95886 (complete study), and 95887 (non-extremity/cranial) are add-on codes reported per extremity or region, not per muscle, and they cannot be billed independently of a nerve conduction study performed the same day. When NCS is not performed on the same date, you bill the legacy codes 95860, 95861, 95863, or 95864 instead. Getting this wrong is one of the fastest routes to an automatic denial.

The top three neurology denial drivers

  • Insufficient documentation: narrative reports that say “normal” or “abnormal” without the supporting numerical data Medicare expects.
  • Incomplete F-wave / H-reflex reporting and same-day E/M charges without supporting referral documentation.
  • Missing clinical history establishing medical necessity, ideally from the referral source.

The Importance of ICD-10 Coding Precision

Neurology ICD-10 codes demand specificity. For headache disorders alone, the coder must distinguish between migraine with aura (G43.1), migraine without aura (G43.0), chronic migraine (G43.7), and tension-type headache (G44.2). Epilepsy codes require the seizure type and whether the condition is intractable (G40.x1) or not intractable (G40.x0).

A common billing error is using an unspecified diagnosis code when a more specific code exists. Payers increasingly reject claims with unspecified codes when clinical documentation supports a precise diagnosis. Linking the correct ICD-10 code to the CPT code is essential; the diagnosis must justify the procedure for the claim to be reimbursed.

Documenting Medical Necessity for Long-Term Care

Many neurology patients require long-term care for chronic conditions like epilepsy, multiple sclerosis, or Parkinson’s disease. For these patients, documenting medical necessity is an ongoing process, not a one-time task. Each follow-up note must justify the continued need for care by detailing the patient’s current status, response to treatment, and any new or changing symptoms. Payers will look for this narrative to approve claims for ongoing management. Simply stating “follow-up for MS” is not enough. Your documentation should reflect the complex decision-making involved in managing these conditions over time, which is a cornerstone of effective practice management and essential for avoiding claim denials for long-term services.

Navigating Place of Service: Hospital vs. Clinic Billing

Where you see your patients matters just as much as the care you provide. Billing for services performed in a hospital setting is fundamentally different from billing for those done in your private clinic. In a hospital, billing is often split: the hospital submits a claim for the facility fee and equipment use (the technical component), while you bill for your professional expertise and interpretation (the professional component, using modifier 26). In your own clinic, you typically bill for both components together as a global service. Clear documentation is your best friend here. Your notes must always support the medical necessity of the service, regardless of the location. Getting this distinction right is a core part of effective practice management that prevents payment delays and ensures you are properly reimbursed for your work.

Identifying and Challenging Underpayments

Beyond outright denials, a more subtle threat to your practice’s revenue is the underpayment. This happens when a payer reimburses you less than the amount stipulated in your contract. Identifying these discrepancies requires a meticulous payment posting process. When an ERA or EOB comes in, your team must compare the allowed amount for each CPT code against your contracted fee schedule. Don’t just accept the payment and write off the difference as a contractual adjustment. Investigating these shortfalls is critical for understanding your practice’s true financial performance and holding payers accountable for their agreed-upon rates.

Common reasons for underpayments include the payer applying an outdated fee schedule, incorrectly bundling services that should be paid separately, or miscalculating patient responsibility. To challenge an underpayment, you must file an appeal that includes a copy of the EOB and the relevant section of your payer contract highlighting the correct fee. This level of detailed follow-up is where having a dedicated medical billing service can make a significant difference, as they have the resources and expertise to challenge every underpaid dollar, ensuring your practice collects the full reimbursement it has earned.

Cost to Collect

This KPI measures how much it costs your practice to collect the money you’re owed. It’s a measure of efficiency, calculated by dividing your total billing costs (including staff salaries, software fees, and clearinghouse charges) by the total amount of money collected. A high cost to collect can silently drain your profitability, even if your overall revenue seems strong. Tracking this metric helps you understand the true financial impact of claim denials, lengthy A/R follow-up, and inefficient workflows. Accurate payment posting is foundational, as it gives your practice a clear view of its financial KPIs and helps you determine if your current billing process is cost-effective or if it’s time to explore a more specialized solution.

Understanding E/M and MDM Levels

Beyond specific procedure and diagnosis codes, Evaluation and Management (E/M) codes are central to neurology billing. These codes reflect the complexity of your patient encounters, focusing on the level of Medical Decision Making (MDM) involved. Think of MDM as the measure of how complex your thought process was during the visit: how many diagnoses you considered, the amount of data you reviewed, and the risk involved in the treatment plan. In neurology, where patient cases are often intricate, accurately capturing the correct E/M level is essential for fair reimbursement. Your documentation is the evidence that supports the level you choose. Without detailed notes justifying your MDM, you risk downcoding and losing revenue, or worse, facing an audit. This is where meticulous record-keeping becomes the backbone of your financial health.

Which KPIs Should Your Neurology Practice Track?

You can’t improve what you don’t measure. Tracking Key Performance Indicators (KPIs) gives you a clear view of your billing department’s health and helps you spot problems early. Focus on metrics like your clean claims rate (the percentage of claims accepted on the first submission), your claim denial rate, and the average number of days in accounts receivable (A/R). A sudden spike in denials or a growing A/R balance can signal an underlying issue that needs immediate attention.

Monitoring these numbers allows you to move from being reactive to proactive. When you see a problem, you can dig into the data to find the root cause, whether it’s a recurring coding error or delays with a specific insurer. Using experts to ensure claims are coded correctly and submitted on time is crucial. They can also work to resolve rejected claims quickly so your practice gets paid for its hard work.

Billing for Tele-Neurology Services

Tele-neurology has become a game-changer, allowing you to connect with patients no matter where they are. It’s an incredible tool for expanding access to care, but it also brings its own set of billing challenges. The rules for virtual appointments are different from in-person visits, and payers have specific requirements you must meet to get reimbursed. This includes getting patient consent, documenting the virtual platform you used, and ensuring the service itself is even approved for telehealth delivery. Without a clear process for managing these details, you risk claim denials that can disrupt your revenue stream. A knowledgeable billing partner can help you handle these rules, ensuring your telehealth services are a financial success, not a compliance headache.

Using Correct Place of Service Codes

One of the most critical details in tele-neurology billing is using the correct Place of Service (POS) code. This simple two-digit code tells the payer where the service happened, and getting it wrong is a surefire way to get a claim rejected. For telehealth, you’ll typically use POS code 02 if the patient is at a location like another clinic, or POS code 10 if they are in their home. These distinctions matter immensely to insurance companies. A generic billing approach might overlook this detail, but a specialized team understands that this precision is non-negotiable for clean claims. This is just one example of how deep neurology billing expertise prevents denials and keeps your practice’s revenue cycle healthy.

Frequently Asked Questions

What neurology CPT codes does AMS handle?

We work the full neurology code set every day, including the EMG and nerve conduction study codes, the EEG codes, the sleep study codes, the evoked potential codes, the autonomic function testing codes, lumbar puncture 62270, and the chronic migraine chemodenervation code 64615 with its onabotulinumtoxinA drug code J0585. 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 units (1 billing unit per unit of drug), the 64615 administration code (inherently bilateral, reported once per session), the required prior auth and step therapy documentation, and the 12-week re-auth cycle. We also track NDC reporting and 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.

How long does neurology billing onboarding take?

Onboarding time depends on your EHR, payer setup and provider enrollment status. 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.

Do you sign a BAA?

Yes. Signed BAA for covered services.
