What 28124 covers

A podiatrist or orthopedic surgeon removes a portion of a toe phalanx to treat localized bone disease or a painful bony prominence. The procedure may be performed in an office-based surgical setting or a hospital or ambulatory surgery facility. The operative report should identify the toe, the phalanx involved, the portion removed, and the clinical reason for the excision.

Select this code when the work is partial removal of phalangeal bone, rather than a defined resection of a distal or proximal condyle or removal of a broader phalangeal segment. Related preoperative care on the day before surgery and related postoperative care for 90 days are included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. 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.

28124 billing questions

When should I use this code instead of a condyle-resection code?

Use this code for partial removal of phalangeal bone without a specifically defined condylar resection. A distal condyle resection points to 28126; a proximal condyle resection points to 28153.

What documentation supports reporting this procedure?

Document the affected toe and phalanx, the segment of bone removed, the reason for excision, and the operative work performed. The record should distinguish a partial phalanx excision from a condylar resection or more extensive phalangectomy.

Is related postoperative care separately reported?

Related postoperative care is included in the 90-day global period, along with the preoperative visit on the day before surgery.

How does Medicare handle bilateral procedures and other procedures in the same session?

A bilateral procedure reported with modifier 50 is paid at 150%. For multiple procedures in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction.

Can an assistant surgeon or co-surgeon be reported?

Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.

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.
