Neurology billing services
Billing for neurology practices that run EEG and EMG labs, treat migraine with injections and manage complex chronic conditions.
Why neurology billing takes specialty knowledge
Neurology combines high-complexity office visits with diagnostic testing that has its own counting rules. Nerve conduction codes depend on the number of studies performed, needle EMG may be added on the same day, and EEG codes change with the length of the recording and whether video was used. Botulinum toxin for chronic migraine needs prior authorization, drug unit reporting and a modifier for any discarded amount.
SFA Solutions codes neurology claims from your reports and notes. We count nerve studies the way CPT defines them, pair EMG add-ons with the right NCS code, bill long-term EEG by setup, monitoring and review time, and handle drug and administration claims for chemodenervation with JZ or JW applied correctly. Authorizations for injections and testing are checked before the appointment to help avoid performing services without approval.

Where neurology practices lose revenue
Nerve conduction and EMG counts
Nerve conduction studies are billed with one code from 95907-95913 based on the total number of studies, counting each nerve and each separate sensory or motor study by CPT's table. Needle EMG done on the same day is billed with add-on codes 95885, 95886 or 95887 alongside the NCS code. Payers may limit the number of studies per diagnosis, so medical necessity must be clear.
EEG and long-term monitoring
Routine EEG uses 95816 (awake and drowsy), 95819 (awake and asleep) or 95822 (sleep only). Long-term EEG uses 95700-95726, which separate technical setup, technologist monitoring and physician review by length of recording and whether video was used. Each component must be billed by the provider who performed it.
Botox for chronic migraine
Chemodenervation for chronic migraine is billed with 64615 and the drug with J0585 per unit. Medicare requires the JZ modifier when no drug was discarded from a single-dose vial and the JW modifier on a separate line for any discarded amount. Most payers require prior authorization and documentation of headache days and prior treatments.
High-complexity E/M visits
Neurology patients often have chronic illnesses with progression or multiple conditions, which supports moderate or high medical decision making. Documenting the data reviewed, including independent interpretation of imaging and discussion with other physicians, helps support 99214 and 99215. Neurobehavioral status exams (96116) are billed separately when performed.
What else affects neurology revenue
A/R challenges in neurology
Botulinum toxin is often bought and billed by the practice, so a denied injection claim leaves the practice carrying the cost of the drug as well as the procedure. Chronic migraine injections are typically given every 12 weeks, and authorizations with a set number of treatments or an end date need to be renewed before they lapse. Long-term EEG and EMG claims can also be held for medical necessity review, which means records requests that need a quick response.
Credentialing considerations
Neurologists enroll under taxonomy 2084N0400X, with separate taxonomies for clinical neurophysiology and other subspecialties that some plans use for EEG and EMG coverage. Some Medicare contractors' nerve conduction and EMG policies set expectations for the training of the physician who performs and interprets the studies. A testing lab set up as a separate entity may need to enroll as an independent diagnostic testing facility, and physicians who read inpatient EEGs need privileges at that hospital.
Payer considerations
Commercial plans may require botulinum toxin to come from a specialty pharmacy instead of buy and bill, which changes who bills the drug. Medicare Advantage plans can apply step therapy to Part B drugs, and many plans want documentation of prior preventive treatments before approving chronic migraine injections. Traditional Medicare covers EEG and NCS under local coverage policies, while commercial plans may send long-term EEG for medical necessity review before the study.
Neurology coding details that affect payment
ICD-10 considerations
Migraine codes in G43 specify chronic or episodic, with or without aura, intractable or not, and with or without status migrainosus, and most botulinum toxin approvals require a chronic migraine code such as G43.709 or G43.719. Epilepsy codes in G40 also distinguish intractable from not intractable and with or without status epilepticus, which affects coverage of long-term EEG. Carpal tunnel syndrome (G56.01, G56.02, G56.03) carries laterality that should match the limbs studied on NCS. Diabetic neuropathy uses the combination code E11.42, and Parkinson's disease codes were expanded in 2023 to G20.A1 and related codes that capture dyskinesia and fluctuations.
Modifiers to watch
| 26 | Used when the neurologist interprets an EEG or nerve study recorded on hospital or other non-owned equipment. |
|---|---|
| TC | Billed by the practice or lab that owns the equipment and employs the technologist when another physician provides the read. |
| 52 | Applied when a routine EEG recording is shorter than the minimum time CPT requires for the code. |
| JW | Reported on a separate line for any onabotulinumtoxinA discarded from a single-dose vial, with the amount documented. |
| 25 | Added to the E/M when a significant, separately documented problem is managed on the same day as a chemodenervation. |
Global periods
Chemodenervation for chronic migraine (64615) carries a 10-day global, so a visit in the following 10 days for the same problem is included. EEG, NCS and EMG are diagnostic tests with no global period.
Medicare considerations
Medicare covers anti-amyloid monoclonal antibodies for Alzheimer's disease under NCD 200.3, which requires the treating clinician to participate in a CMS-approved registry. Most MACs publish local policies for nerve conduction studies and EMG that limit the number of studies per diagnosis and expect the physician to perform or directly supervise the testing, and studies done with handheld automated devices (95905) are restricted. Medicare covers botulinum toxin under Part B when it is bought and administered in the office.
Neurology billing KPIs to track
- Botulinum toxin authorization renewal rate. Injections given after an authorization lapses leave the practice carrying both drug and procedure costs.
- Drug cost to payment margin. Comparing J0585 payment to acquisition cost by payer shows whether buy and bill still makes sense for each plan.
- NCS studies per patient. Study counts above payer norms invite medical necessity review, so monitoring them shows audit exposure.
- Long-term EEG component billing accuracy. Setup, monitoring and review components billed by the wrong entity or length lead to denials and recoupments.
Neurology billing audit checklist
- Count nerve conduction studies against CPT's table and confirm the billed code matches the total.
- Confirm needle EMG add-on codes match the number of extremities and muscles tested.
- Check that long-term EEG claims match the recording length and whether video was used.
- Verify J0585 units billed and wasted match the vial size and the dose documented.
- Review migraine claims for a chronic migraine diagnosis and a current authorization.
- Confirm 26 or TC is applied correctly on EEG and NCS performed outside the practice's own equipment.

Neurology billing questions
How do I count nerve conduction studies?
Each motor or sensory study of a nerve counts as one study, following CPT's table of nerves. Add up the total for the session and bill the one NCS code that matches the count.
Can EMG and NCS be billed on the same day?
Yes. Bill the NCS code for the number of studies and the needle EMG add-on code (95885, 95886 or 95887) that matches the extremities and muscles tested.
What are JZ and JW modifiers?
They report drug wastage from single-dose containers. JW goes on a line for any amount discarded, and JZ is used when no drug was discarded. Medicare requires one or the other on single-dose drug claims.
Does Botox for migraine need prior authorization?
Most commercial and Medicare Advantage plans require it, usually with documentation of chronic migraine and prior treatments that did not work. We submit the request and track renewals.
Who bills each part of a long-term EEG?
The technical setup and monitoring are billed by the entity that owns the equipment and employs the technologist, and the professional review is billed by the interpreting neurologist.
