Neurology billing hinges on time-based EMG/NCS coding (95860-95887), Botox J0585 dosing with JW waste reporting, and the infusion administration hierarchy (96360-96549). Add EEG global periods and modifier 25 on same-day E/M and general billers miss revenue on every encounter. MedFactor delivers neurology-specific RCM that protects every claim.
From general neurology and epilepsy to neuromuscular and movement disorders, we tailor billing to the coding rules of every neurology subspecialty.
E/M-coded consultations, chronic disease management, and diagnostic testing with modifier 25 accuracy on same-day procedures.
Routine (95950) and prolonged EEG (95951-95956), video EEG monitoring, and global-period frequency tracking per payer.
Botox chemodenervation (64615/64612) with J0585 onabotulinumtoxinA dosing, JW waste reporting, and add-on muscle accuracy.
Time-based needle EMG (95860-95887) and NCS (95804-95816) with limb-based and total-study coding rules.
Migraine (G43) infusion therapy, infusion administration hierarchy 96360-96549, and Botox for chronic migraine.
Cognitive testing (96116), neurocognitive evaluation, and chronic care management for degenerative conditions.
OnabotulinumtoxinA (J0585) is billed per unit dosed with chemodenervation (64615 head/neck, 64612 limb) and JW for discarded waste, while infusion administration follows a strict initial/sequential/add-on hierarchy under 96360-96549. This is the largest source of neurology drug-and-procedure denials.
One Botox session bills the chemodenervation base code, each additional muscle as an add-on, the J0585 drug units, and JW for any discarded toxin — while infusion therapy follows its own administration hierarchy.
Neurology billing is governed by time-based EMG/NCS coding, Botox J-code waste rules, and infusion administration hierarchies that general billing companies cannot navigate effectively.
Needle EMG (95860-95887) is time-based and limb-based; wrong time tier or limb count drops the study to a lower-paying code.
OnabotulinumtoxinA (J0585) requires JW modifier for discarded units; missing JW forfeits drug waste reimbursement on every vial.
Infusion codes 96360-96549 follow a strict initial/sequential/concurrent hierarchy; wrong sequencing denies the whole infusion claim.
Routine and prolonged EEG (95950-95956) denied for frequency overage or when billed inside a global period without the right modifier.
Same-day E/M with EMG, Botox, or infusion denied when modifier 25 isn’t appended to show a separately significant encounter.
Botox and infusion biologics denied when prior authorization criteria (diagnosis, frequency, prior-therapy failure) aren’t documented.

Real results from neurology practices that partnered with MedFactor for specialty revenue cycle management.
A neuromuscular clinic was billing all needle EMG studies at the single-limb tier (95860) regardless of limbs studied. MedFactor implemented per-limb time-tier sequencing across 95860-95887, recovering substantial study revenue in eight months.
A headache and infusion practice was dropping infusion additional-hour codes (96366) and never reporting discarded Botox with JW. MedFactor implemented the full infusion hierarchy and JW waste reporting, recovering drug and administration revenue.
A movement-disorders group was under-dosing J0585 units and omitting the limb chemodenervation add-on (64612). MedFactor implemented exact-unit dosing with JW and add-on muscle capture, protecting Botox therapy revenue.
No matter where your neurology practice operates, our team understands the payer landscape and regulatory requirements in your region.
Deep coding knowledge across Medicare, Medicaid, and all major commercial payers for neurology services.
J0585 dosing limits and chronic-migraine Botox coverage criteria applied correctly across all 50 states.

State-by-state prior authorization support for Botox, infusion biologics, and disease-modifying therapy.
Common questions from neurology practices considering MedFactor’s specialty RCM services.
Needle EMG codes 95860-95887 are time- and limb-based. 95860 covers one limb, 95861 two limbs, and 95870 is a limited study of specific muscles. Nerve conduction studies (95804-95816) are tiered by the number of studies performed: 95804 for 1-2 studies, 95805 for 3-4, 95810 for 5-6, and 95816 for 7 or more. Combined EMG/NCS codes (95834-95840) follow similar tier logic. The correct code is selected by the documented time and limb/study count — billing the wrong tier downcodes the study and loses per-study revenue. We map every study to the correct tier before submission.
OnabotulinumtoxinA is billed under HCPCS J0585 per unit dosed. The chemodenervation procedure is billed separately — 64615 for head/neck muscles and 64612 for limb muscles, with 64612 typically an add-on for additional muscle groups in the same session. When any toxin is discarded (a vial cannot be split across patients in many payer rules), the discarded units are reported on a separate line with the JW modifier so the practice is reimbursed for wasted drug. We reconcile dosed versus wasted units on every Botox session and append JW for any discard, which is one of the most commonly missed neurology revenue points.
Infusion administration codes 96360-96549 follow a strict hierarchy. Therapeutic, prophylactic, or diagnostic infusion (96365) is the initial code for the first hour of a non-chemotherapy infusion, with 96366 for each additional hour. Sequential infusions of a different drug/substance use 96367 (first sequential) and 96368 (each additional sequential). Concurrent infusions use 96360-96361 for hydration when run with another infusion. Chemotherapy administration uses 96413 and its add-ons. The initial code is the highest-paying service, and add-ons must be sequenced correctly or the entire infusion claim is denied. We sequence every infusion per the hierarchy before submission.
Modifier 25 is appended to an E/M code (such as 99202-99215) when a separately significant, same-day evaluation and management service is performed with a procedure like EMG/NCS, Botox chemodenervation, or infusion administration. Without modifier 25, the E/M is denied as bundled into the procedure. The E/M note must document a separately identifiable service beyond the procedure’s inherent evaluation. We append modifier 25 only where the documentation supports a separate encounter, protecting the E/M revenue without risking audit exposure.
Routine EEG (95950), prolonged EEG (95951-95956), and video EEG monitoring have payer-specific frequency limits — often a set number of studies per year per diagnosis — and some carry global periods. Repeat EEG beyond the frequency limit is denied without documented medical necessity, and EEG performed inside a post-procedure global period may require the right modifier to bill separately. We track EEG frequency per patient, pair each claim with the supporting diagnosis (such as G40 epilepsy), and apply global-period modifiers where appropriate so EEG monitoring is paid rather than denied.
Botox for chronic migraine and infusion biologics for multiple sclerosis and other conditions typically require prior authorization based on diagnosis, documented failure of prior therapy, and frequency criteria. We gather the supporting documentation (such as G43 migraine with documented preventive failure, G35 multiple sclerosis, and prior-therapy notes) and submit authorization before treatment. This prevents the post-treatment denials that occur when biologic prior auth is missing — one of the costliest neurology denial categories.
