Summary & Overview
HCPCS G4002: Electrophysiology Cardiac Specialist MIPS Specialty Set
HCPCS Level II code G4002 designates the Electrophysiology cardiac specialist MIPS specialty set, a quality reporting construct for clinicians in cardiac electrophysiology. Nationally, MIPS specialty sets are used to align performance measurement with clinical practice areas and affect Medicare reimbursement adjustments and clinician performance reporting; specialty-specific sets like this one focus measures relevant to electrophysiology care.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what this code represents, the clinical context for electrophysiology specialty reporting, and the types of information typically included in an analysis: national applicability of the measure set, payer coverage considerations, and where clinicians report specialty-specific measures.
This publication does not provide state-specific guidance. It provides benchmark- and policy-focused context for national audiences, outlines what to expect when this HCPCS Level II code applies to quality reporting, and identifies gaps when source data are not available. Data not provided in the input (for example, linked taxonomies, ICD-10 mappings, and related billing codes) are noted as unavailable.

Clinical & Coding Specifications
Clinical Context
A 68-year-old male with symptomatic paroxysmal atrial fibrillation and recurrent palpitations is referred to an electrophysiology cardiac specialist for risk stratification and procedure planning under the MIPS specialty set G4002. The patient presents to an outpatient electrophysiology clinic for pre-procedure evaluation, review of prior cardiac testing (ECG, ambulatory monitoring), medication reconciliation, anticoagulation assessment, and shared decision-making regarding catheter ablation versus device therapy. The clinical workflow includes: a focused history and physical, review of prior imaging and rhythm strips, ordering transesophageal echocardiography or CT when indicated, pre-procedure labs, peri-procedural risk scoring (CHA2DS2-VASc), documentation of informed consent, and coordination with the cardiac catheterization lab for scheduling. On the day of the procedure the electrophysiology team documents time in/out, procedural complexity, anesthesia needs, and any intra-procedural complications; post-procedure follow-up includes device interrogation or ambulatory monitoring and medication adjustments.
