CPT code 28800: Foot amputation2026 Medicare rate & RVUs

Medicare pays $491.33 for 28800 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 28800 covers

This operation removes the foot at the midtarsal level, commonly described as a Chopart amputation, while leaving the heel portion of the foot. It may be performed for extensive infection, gangrene, nonhealing ischemic tissue, or severe trauma when a more distal amputation cannot adequately remove affected tissue. An orthopedic or foot-and-ankle surgeon typically performs it in an operating room; vascular surgeons may be involved in care for ischemic disease.

Report the code when the operative level is the midfoot, not the metatarsals or an individual toe. The operative report should establish the amputation level, laterality, indication, and extent of tissue removal. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is 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.
