What 28122 covers

A foot and ankle surgeon, commonly an orthopedic surgeon or podiatrist, reports this procedure when completely excising a tarsal bone other than the talus or calcaneus. Examples include a cuboid or cuneiform. The operation may address a symptomatic bony prominence, deformity, arthritic change, or other bone pathology. The operative report should identify the bone removed and describe complete excision rather than a limited shaving or partial resection.

Select this code by the bone and extent of removal: it is for complete excision of another tarsal bone, not partial excision of the talus or calcaneus. Document the clinical indication, operative findings, and extent of bone removal. Medicare 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 the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

How does 28122 differ from 28120?

28122 is for complete excision of another tarsal bone, such as a cuboid or cuneiform. 28120 is for partial excision of the talus or calcaneus.

Does a partial shaving of a cuboid or cuneiform support 28122?

No. The operative documentation should support complete excision of the tarsal bone; a limited resection does not meet that selection criterion.

How should bilateral procedures be reported?

Report bilateral work with modifier 50. CMS pays the bilateral procedure at 150%.

What documentation supports this code?

Identify the tarsal bone removed, the reason for surgery, and the operative extent showing complete excision. The record should distinguish this work from partial excision of the talus or calcaneus.

How does Medicare handle other procedures performed in the same session?

Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50%.

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.
