Summary & Overview
HCPCS G4015: Neurology MIPS Specialty Set
HCPCS Level II code G4015 identifies the Neurology MIPS specialty set used for quality reporting by neurology clinicians. As a national-level quality reporting indicator, this code matters because it standardizes the measures neurology providers use for MIPS performance, affecting public reporting and value-based payment programs. The code is relevant across major payers and federal programs that incorporate MIPS results into reimbursement and network performance assessments.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of what G4015 represents, how it is used in neurology quality reporting, and its typical clinical and administrative settings. The publication outlines benchmarks where available, summarizes policy and reporting implications tied to MIPS specialty measures, and provides clinical context for neurology practices participating in MIPS.
This summary is intended for national audiences including neurology clinicians, practice administrators, and payor policy teams who need a clear, actionable description of the code, its purpose within quality reporting, and the types of settings where it is applied. Data not available in the input will be noted as such in the detailed sections.

Clinical & Coding Specifications
Clinical Context
A neurology practice participates in the Merit-based Incentive Payment System (MIPS) and submits the Neurology MIPS specialty set (G4015) to report specialty-specific performance and quality measures. Typical workflow: a patient with episodic or chronic neurologic complaints (for example, migraine, seizure disorder, or Parkinson disease) presents to an outpatient neurology clinic for evaluation and longitudinal management. The encounter includes history, focused neurologic examination, review of prior imaging and studies, medication reconciliation, and development or modification of a care plan. Staff document quality measures and submit required MIPS data elements under the Neurology specialty set. The service is most commonly delivered in an outpatient clinic or physician office, occasionally in telehealth visits when permitted by payer MIPS guidance, and may accompany procedures such as electroencephalography or botulinum toxin injections when those services are performed during the same episode of care.
