CPT code 92974 represents intra‑procedural brachytherapy performed at the same session as treatment of coronary arterial stenosis. The code captures placement of radioactive seeds near a site of arterial blockage as an adjunct to techniques used to restore vessel patency. While less common since the advent of modern drug‑eluting stents, this code remains relevant for documenting specialized implantable radiation therapy performed during interventional cardiology procedures.

Key payers in this national analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context for when brachytherapy is used as an adjunct to stenosis treatment, the typical site of service (hospital catheterization laboratory or interventional suite), and payer coverage considerations at a high level. Data limitations in the input are noted where applicable: associated taxonomies, ICD‑10 diagnoses, and specific related procedure codes are not provided.

This publication summarizes benchmarks, coding guidance, and policy considerations relevant to documentation and claims for CPT code 92974, and outlines what to review when evaluating coverage and reimbursement for intra‑procedural coronary brachytherapy across major national payers.
