About 28024: Toe interphalangeal joint arthrotomy
Reports surgical opening of a toe interphalangeal joint to inspect it, drain it, or remove a loose or foreign body.
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.

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?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant surgeon or co-surgeon be paid?
Assistant-at-surgery payment is restricted for this service. CMS does not permit co-surgeons or team surgery.
