CPT code 92945: CTO revascularization, antegrade and retrograde2026 Medicare rate & RVUs

Medicare pays $631.95 for 92945 nationally in a facility.

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

What 92945 covers

An interventional cardiologist reports this service when reopening a chronic total occlusion in one coronary vessel requires both antegrade and retrograde crossing approaches. The work takes place during a catheter-based coronary intervention, typically in a hospital catheterization laboratory. The two approaches describe how the operator reaches and crosses the occlusion; they do not represent treatment of two separate vessels.

The record should identify the target vessel, establish that the occlusion is chronic, and support use of both crossing approaches. Report the code once for the treated vessel; ordinary balloon or stent treatment in that same vessel is part of the revascularization service when performed. The procedure has a 0-day global period, so same-day preoperative and postoperative care are included. 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. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeon and team-surgery payment are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
