CPT code 93572 is an add-on procedural code for invasive physiologic assessment of coronary arteries or bypass grafts during coronary angiography using a Doppler or pressure wire; it is reported for each additional vessel after the first. This service, which may include pharmacologic stress to increase blood flow, provides clinicians with objective hemodynamic data such as fractional flow reserve (FFR) or coronary flow reserve (CFR) to guide revascularization decisions. Nationally, these measurements influence care pathways for patients with ischemic heart disease and affect utilization patterns in catheterization laboratories.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The analysis covers coverage trends and coding practice implications across commercial and public payers.

Readers will find a concise explanation of the clinical context and service setting, typical billing considerations for an add-on vessel-based measurement, and the types of benchmarks and policy updates that commonly affect adoption and reimbursement. Where payer-specific data are not provided in the input, the publication notes that "Data not available in the input." The content is intended for health system billing leads, cardiology administrators, and policy analysts seeking a national overview of coding and clinical relevance for invasive coronary physiologic assessment.
