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.

28122 billing questions

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?

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.
