What 28288 covers

A foot surgeon, commonly an orthopedic surgeon or podiatrist, removes part of a toe phalanx head to address a painful bony prominence and related pressure or irritation. The procedure may be performed in a surgical facility or office-based setting, depending on the case. The operative note should identify the toe and bone treated, the prominence or deformity prompting surgery, and the extent of bone removed.

Report 28288 for partial removal involving the head of a toe phalanx, rather than a different phalangeal site or a procedure directed at correcting the toe deformity itself. This major surgery has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

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.
