Neurology Billing Services
Neurology revenue does not come from the office visit. It comes from the diagnostic lab, the infusion chair and the injection cycle, and each of those pays only when paperwork unrelated to clinical skill is already in place. We bill neurology practices across all three. The diagnostic side is one of the most test-heavy environments in outpatient medicine — routine and sleep EEG, long-term video monitoring billed by the hours recorded, nerve conduction counts paired with needle studies, evoked potentials and polysomnography — and every one of those codes splits into a technical component and a separately priced interpretation, so the first question we settle on each claim is what was performed and who owns the recording equipment. Where a plan requires prior authorization for EEG, an authorization opened after the recording starts does not cover it retroactively, so we open it at order time rather than at the read, which matters most on an epilepsy monitoring unit where the paperwork tends to lag the admission. Botox for chronic migraine is a two-line claim, the injection and the drug units, and it turns on a reconciliation rather than on the coding: the units the plan authorized, the units drawn from the vial, the units documented as administered by site, and the units billed all have to agree, with any discarded remainder reported on its own waste line. Medicare has no national coverage determination for the injection, so the criteria that govern a given patient come from that contractor's local policy or from the commercial plan's own — we build the qualification packet to the one that actually applies, and rebuild it before each cycle rather than once. On the infusion side we file the plan's medical exception with the claim instead of after the denial, and we check the quarterly Part B payment limits before purchasing so inventory is not bought against a stale figure. We run advanced imaging authorizations through eviCore, AIM and National Imaging Associates, keep NIH Stroke Scale documentation on thrombolytic encounters, and bill prolonged service time on long dementia and refractory-epilepsy visits instead of stopping at the top office level. Written for practices running their own testing suites, infusion programs or Botox panels.

What do neurology billing services include?
We bill neurology practices across two separate workflows, because they break in different places. On the diagnostic side the questions are which study was performed and how long it ran, and who owns the equipment — EEG, long-term monitoring, nerve conduction and needle EMG all split into a technical and a professional component, and the professional-only claim is the right one whenever the recording equipment belongs to the facility. On the infusion and injection side the questions are all about units: the authorization has to cover the dose the plan approved, the dose drawn has to match the dose administered in the note, and the units billed have to equal the units administered plus any discarded remainder, which is reported separately with modifier JW. Rates on this page are Medicare CY2026 national unadjusted amounts computed from the CMS relative value file, and Part B drug amounts come from the quarterly Medicare Part B payment limit file — neither is what a commercial contract pays, and your locality adjustment moves the physician fee schedule side.
- EEG coded to the study actually performed — 95816 is awake and drowsy, 95819 is awake and asleep — with the professional-component split applied where the recording equipment belongs to the facility
- Long-term monitoring interpretation coded to the hours recorded and whether video ran, not to a single house code
- Nerve conduction counts paired with limited or complete needle EMG, coded within the per-indication maximums the contractor's LCD adopts from CPT Appendix J
- Botox filed as 64615 plus J0585 units, with the authorization, the units drawn, the units administered and the JW waste line reconciled to each other before the claim goes out
- Prolonged time billed where it is documented — G2212 for Medicare, which does not recognize 99417 — instead of stopping at 99215 on a long dementia or refractory-epilepsy workup

Common Billing Friction in Neurology
Botox for chronic migraine: unit reconciliation, and coverage criteria that are contractor-specific
The encounter bills as two lines — CPT 64615 for chemodenervation of the muscles innervated by the facial, trigeminal, cervical spinal and accessory nerves, and J0585 for onabotulinumtoxinA per unit administered — and the second line is where the money is lost. The reconciliation has four numbers that must agree: the units the plan authorized, the units drawn from the vial, the units documented as administered by site in the note, and the units on the claim. Anything drawn from a single-use vial and not administered is reported separately with modifier JW as discarded drug, not folded into the administered line. The FDA labeling for this indication is 155 Units divided across seven head and neck muscle areas, retreated every 12 weeks. Coverage criteria are not national: there is no NCD for the injection, so each Medicare contractor publishes its own LCD, and they differ. Palmetto GBA's LCD L33458 (revision effective May 27, 2021) defines chronic migraine as at least 15 headache days per month with headache lasting four hours or longer, and treats the headache as intractable only on failed trials of at least three preventive pharmacologic therapies titrated to maximum tolerated dose, or contraindication to or intolerance of them. Commercial plans publish their own criteria and their own re-authorization interval. The documentation packet — headache diary, preventive-medication history, indication — has to be built to the policy that actually governs the patient, and rebuilt before each cycle, not once. The two lines are also priced by different mechanisms, which is why the drug line carries all the variance: on the CY2026 Medicare physician fee schedule 64615 is $156.98 national unadjusted in a non-facility setting and $109.22 in a facility, a fixed and modest amount, while J0585 is priced off average sales price and revised quarterly. The trials behind the chronic migraine indication used 155–195 Units, above the 155-Unit labeled total, and a protocol that follows the pain into that range is exactly where an authorized dose and an administered dose come apart.
Nerve conduction and needle EMG: per-indication study maximums and same-day bundling
Nerve conduction studies are counted, not itemized: 95907 covers 1–2 studies, 95908 3–4, 95909 5–6, 95910 7–8, 95911 9–10, 95912 11–12 and 95913 13 or more, and they pair with needle EMG reported as 95885 (limited) or 95886 (complete) per extremity. The number of studies that will be paid is set by the clinical indication rather than by a flat cap: Novitas LCD L35081 (Nerve Conduction Studies and Electromyography, effective December 10, 2023) treats studies beyond the maximum recommended in CPT Appendix J, the electrodiagnostic listing of sensory, motor and mixed nerves, as not reasonable and necessary, and separately limits repeat testing to two studies per 12-month period per diagnosis per provider for carpal tunnel, radiculopathy, mononeuropathy, polyneuropathy, myopathy and neuromuscular junction disorders, and three for motor neuron disease and plexopathy, with exceptions for a second opinion or a second diagnosis. On top of that, some payers apply a multiple-procedure reduction when nerve conduction and needle EMG are reported on the same day. Both problems are answered by the same document: a report that names each nerve tested, the stimulation and recording sites, the muscles sampled, and why the study was needed for this indication. One placement error is worth naming separately: 95885 and 95886 are add-on codes to a nerve conduction study, so a needle EMG performed without nerve conduction on the same day is reported from the 95860–95864 family by number of extremities instead.
Long-term EEG monitoring: the interpretation codes are keyed to hours recorded and whether video ran
This is the family most often miscoded, because the codes look sequential and are not. On the CY2026 Medicare physician fee schedule the physician or QHP interpretation codes run 95717 and 95718 for a 2- to 12-hour recording without and with video, 95719 and 95720 for each increment beyond 12 hours without and with video, 95721 and 95722 for more than 36 and up to 60 hours, 95723 and 95724 for more than 60 and up to 84 hours, and 95725 and 95726 for more than 84 hours. None of these is the technical recording component — that is a separate set of codes the fee schedule leaves to contractor pricing rather than valuing nationally, which is why a hospital's EEG technical claim and the neurologist's interpretation claim never look alike. Two things therefore have to come off the study record before coding: the total recorded hours and whether video ran simultaneously. Prior authorization is the other half of the problem — where a plan requires it for EEG, an authorization obtained after the recording starts does not retroactively cover it, so on an epilepsy monitoring unit the authorization has to be opened with the admission, not with the read. The same technical-and-professional split runs across the rest of the neurodiagnostic suite. Routine and extended EEG on 95812–95830, evoked potentials on 95925–95938, and polysomnography and sleep studies on 95805–95811 are each coded to the study actually performed and then divided between the facility that recorded it and the physician who read it, so the same two questions — what was performed, and who owns the equipment — decide every claim in the lab.
MS and migraine biologic infusions: buy-and-bill inventory, authorization, and frequency policy
Multiple sclerosis disease-modifying therapy and migraine prevention run through buy-and-bill biologics billed per milligram: natalizumab J2323, ocrelizumab J2350 and eptinezumab J3032, each paired with infusion administration codes 96365 for the initial hour and 96366 for each additional hour. Because these are Part B drugs, Medicare prices them off average sales price and republishes the payment limits every quarter — for October through December 2026 the limits are $23.927 per mg for J2323, $60.689 per mg for J2350 and $21.243 per mg for J3032 — so a practice that buys inventory against a stale limit is carrying the spread itself. The billing reconciliation is the same one as for Botox and just as unforgiving: authorized dose, dose drawn, dose administered in the note, dose billed, and any discarded remainder on its own JW line. Separately, a plan may run a frequency edit that does not match the labeled dosing interval; where that happens the answer is a medical-exception request filed against that plan's own published policy, and the interval has to be tracked forward so the next infusion is scheduled inside it rather than appealed after it.
Prolonged service capture, and the Medicare-versus-CPT divergence
Complex neurology office visits routinely run past the time the top-level E/M code contemplates — a new multiple sclerosis evaluation, a dementia workup, a refractory epilepsy consultation. The post-2021 office E/M revisions created CPT 99417 as the prolonged-service add-on for 99205 and 99215, but Medicare does not use it: on the CY2026 physician fee schedule 99417 carries status I, meaning it is not valid for Medicare, while HCPCS G2212 is the payable code and is priced at $34.07 national unadjusted in a non-facility setting. So the same documented time is billed with different codes depending on the payer, and a practice that files only 99417 collects nothing from Medicare for the extra time it documented. What makes the code billable is a time statement in the note that identifies the total time on the date of the encounter, not an impression that the visit ran long.
Neurology-Specific Payer Issues We Watch For
Plans requiring EEG prior authorization
Issue: Where a plan requires prior authorization for EEG, an authorization obtained after the recording has already started does not cover it retroactively — which hits epilepsy monitoring units hardest, because the authorization paperwork tends to lag the admission
Our approach: We open the authorization when the study is ordered and confirm it is active before the recording date, and we check each plan's current policy for whether routine EEG is included rather than assuming it is not
Plans applying same-day NCS and EMG reductions
Issue: Some plans apply a multiple-procedure reduction when nerve conduction studies (95907–95913) and needle EMG (95885–95886) are reported on the same day, treating them as one service even where both were needed for the diagnosis
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: There is no national coverage determination for onabotulinumtoxinA in chronic migraine, so each Medicare contractor sets its own criteria by LCD and they are not identical — Palmetto GBA's L33458, for instance, requires failed trials of at least three preventive pharmacologic therapies, where other policies and commercial plans set a different number
Our approach: We identify the LCD or plan policy that actually governs the patient, build the qualification packet to that document's criteria, and record which policy and revision date the requirement came from
Plans with infusion frequency policies
Issue: A plan's frequency policy for a neurology infusion can diverge from the labeled dosing interval, so a clinically appropriate infusion is denied as too soon
Our approach: We track each plan's stated interval per drug, schedule forward inside it where we can, and file a medical-exception request against that plan's own published policy where we cannot
What We Handle
EEG coding and long-term monitoring interpretation keyed to hours and video
Routine EEG coded to the study actually performed — 95816 awake and drowsy, 95819 awake and asleep — and long-term monitoring interpretation coded to the recorded hours and whether video ran (95717–95726), with the professional-component split applied where the recording equipment belongs to the facility.
EMG and nerve conduction billing (95907–95913, 95885–95886) within per-indication maximums
Count-based nerve conduction coding paired with limited or complete needle EMG per extremity, kept inside the maximum number of studies the contractor's LCD adopts from CPT Appendix J, with the per-nerve report that answers both the medical-necessity question and any same-day bundling edit.
Botox 64615 + J0585 with four-way unit reconciliation
Authorization, units drawn, units documented as administered by site, and units billed reconciled to each other before the claim goes out, with discarded single-use vial remainder on its own JW line. Coverage packet built to the criteria that actually govern the patient — the contractor's LCD or the plan's policy — and rebuilt before each injection cycle.
MS and migraine infusion buy-and-bill (J2323, J2350, J3032) priced off the current quarter
Per-milligram J-code billing paired with 96365 and 96366 administration, checked against the Part B payment limits CMS republishes quarterly so purchasing is not working from a stale figure, plus medical-exception filing where a plan's frequency policy diverges from the labeled interval.
Advanced neuroimaging prior authorization through the plan's radiology benefit manager
Brain MRI, MRA, CT and PET authorization filed to whichever radiology benefit manager the member's plan delegates to, with the neurological exam findings, prior imaging and symptom history packaged to that vendor's current criteria — vendors and criteria change, so we confirm which one holds the plan before filing rather than working from last year's routing.
Prolonged service capture — G2212 for Medicare, 99417 where the plan recognizes it
Time-documented prolonged-service billing on 99205 and 99215 visits that exceed the code's time threshold. Medicare assigns 99417 status I and pays G2212 instead, so the routing is per payer and the note has to state the total time on the date of the encounter.

Key Neurology CPT Codes
| CPT Code | Description | Medicare Amount CY2026 national, non-facility |
|---|---|---|
| 95819 | EEG including recording awake and asleep | $482 |
| 95907 | Nerve conduction studies, 1–2 studies | $94 |
| 95886 | Needle EMG, complete, each extremity | $100 |
| 95816 | EEG including recording awake and drowsy | $414 |
| 99215 | Office visit, established patient, high level | $192 |
| 96372 | Therapeutic or diagnostic injection, subcutaneous or intramuscular | $15 |
| J0585 | OnabotulinumtoxinA, 1 unit — a Part B drug priced off average sales price rather than the physician fee schedule; CMS set the payment limit at $6.514 per unit for October through December 2026 and revises it quarterly | — |
| 96365 | Intravenous infusion, therapeutic, initial up to 1 hour | $67 |
Amounts are the Medicare national unadjusted non-facility amounts for CY2026, computed from the published CMS relative value file. They are not what a commercial payer pays, and your locality adjustment moves them. A dash means Medicare publishes no amount for that code — because it is non-covered, bundled, or priced outside the fee schedule.
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 has two billing operations, not one. The diagnostic side is decided by what the study record says — hours, video, who owns the equipment. The infusion side is decided by whether four unit counts agree. Practices that run them as a single queue lose money on both.”

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
- Add-on codes for documented time beyond what the top-level office E/M code contemplates. CPT 99417 attaches to 99205 and 99215, but Medicare assigns it status I on the CY2026 physician fee schedule and pays HCPCS G2212 instead, so the code used depends on the payer. The predecessor codes 99354–99357 are no longer on the fee schedule. What makes either billable is a note stating the total time on the date of the encounter.
- Nerve Conduction Study (NCS)
- Electrodiagnostic test measuring nerve signal speed and amplitude, coded by the number of studies performed (95907–95913). The report must name each nerve tested with its stimulation and recording sites, and the number of studies supported is set by the clinical indication rather than by a flat cap.
- 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 practice purchases the biologic, administers it, and bills the payer for both the drug (J-code) and the administration (96365–96368). It carries inventory risk, because Medicare prices Part B drugs off average sales price and republishes the payment limits quarterly, and it requires documenting any discarded remainder separately.

See how specialty-specific billing support can improve reimbursement visibility for neurology billing services.
Request ReviewHow do you bill for Botox injections for migraine?
We bill it as two lines: CPT 64615 for the chemodenervation and J0585 for the units of onabotulinumtoxinA administered, with any remainder discarded from a single-use vial reported separately on a JW line. Before the claim goes out we reconcile four numbers — the units authorized, the units drawn, the units documented as administered by site, and the units billed. Coverage criteria are not national: Medicare has no NCD for this, so the governing document is either the local contractor's LCD or the commercial plan's own policy, and they differ on the headache-day definition and on how many failed preventive therapies they require. We build the documentation packet to the policy that applies to that patient, and rebuild it before each 12-week cycle rather than once.
What are the limits on EMG/nerve conduction studies per session?
There is no single number. The maximum is set by the clinical indication: Medicare contractors adopt the recommended maximum number of studies in CPT Appendix J, the electrodiagnostic listing of sensory, motor and mixed nerves, and treat studies beyond it as not reasonable and necessary. Novitas LCD L35081, effective December 10, 2023, also limits repeat testing to two studies per 12-month period per diagnosis per provider for carpal tunnel, radiculopathy, mononeuropathy, polyneuropathy, myopathy and neuromuscular junction disorders, and three for motor neuron disease and plexopathy, with exceptions where a second provider or a second diagnosis is involved. We code to the indication and to the studies the report documents, and we check the maximum that applies in your contractor's jurisdiction before the claim is filed.
Do you handle prior authorization for neurological imaging?
Yes. Advanced neuroimaging authorizations usually go to a radiology benefit manager the plan delegates to rather than to the plan itself, and which vendor holds which plan changes, so we confirm the current routing before filing. The submission carries the neurological exam findings, symptom history and prior imaging results packaged to that vendor's published criteria, and we track the authorization against the scheduled study date so nothing is performed on an expired or pending approval.
