CPT code 92943: CTO PCI, antegrade approach2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 92943 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 92943 covers

An interventional cardiologist performs this procedure in a cardiac catheterization lab to reopen a chronically and completely occluded coronary vessel using an antegrade crossing approach. The intervention may include balloon angioplasty, atherectomy, or stent placement as needed to restore flow in the treated vessel. Hospital outpatient and inpatient cath lab settings are typical.

Select the code for a chronic total occlusion treated antegrade in one vessel; use the approach and target vessel documented in the procedure report to distinguish it from other coronary intervention codes. The report should identify the occlusion, the vessel treated, the crossing approach, and the revascularization performed. Angioplasty, atherectomy, and stenting in that same vessel are included in the CTO service. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
