What 28024 covers

This service involves surgically opening an interphalangeal joint of a toe to inspect the joint, drain it, or remove a loose or foreign body. A foot and ankle surgeon or podiatric surgeon may perform it in an operating room or another surgical setting when the problem is within the toe joint, rather than a neighboring tendon or soft-tissue structure.

Choose the code based on the joint treated and the work documented. The operative note should identify the toe and joint, the reason for opening it, and any drainage or material removed. CMS assigns 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 for this descriptor. Assistant-at-surgery payment is restricted; 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.

28024 billing questions

How is this different from an arthrotomy of another foot joint?

This code is for an interphalangeal joint of a toe. Use the applicable neighboring arthrotomy code when the operative report identifies a different foot joint.

Can this be reported for a toe joint biopsy?

The defining work is opening the toe joint for exploration, drainage, or removal of a loose or foreign body. A procedure focused on sampling the toe joint lining is represented by the toe-joint biopsy code, 28054.

Should modifier 50 be used for both feet?

No. Modifier 50 is inappropriate for this descriptor; document the treated toe joint or joints.

What postoperative care is included?

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.
