CPT code 92920: Coronary angioplasty, single vessel, no stent2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 92920 in California.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 92920 covers

An interventional cardiologist advances a catheter-mounted balloon through the vascular system to widen a narrowed coronary artery or branch. The service is typically performed in a hospital cardiac catheterization laboratory for coronary artery disease. This code describes balloon angioplasty without stent placement or atherectomy in the treated vessel; balloon dilation used as part of a stent or atherectomy service is included in that service when performed.

Report one unit for treatment of one major artery or branch, supported by the procedure report identifying the treated vessel and intervention. For each additional qualifying branch, 92921 is the add-on code. The procedure has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
