What 28313 covers

CPT 28313 covers surgical correction of an angular toe deformity using soft-tissue procedures alone. A common clinical situation is an overlapping lesser toe, such as a second toe that crosses over an adjacent toe. The surgeon or podiatrist rebalances soft tissue around the affected toe to improve its alignment; the procedure is performed in an operating room or ambulatory surgery setting. This code is not the choice when the documented correction includes an osteotomy of a toe bone.

Report the service for each toe corrected and document the deformity, the toe involved, and the soft-tissue work performed. Medicare assigns a 90-day global period, which includes the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery, and co-surgeon and team-surgery billing 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.

28313 billing questions

When is 28313 preferable to 28312?

Use 28313 for angular toe correction performed with soft-tissue procedures alone. CPT 28312 describes a bony osteotomy of a toe phalanx.

Does 28313 include correction of an overlapping toe?

Yes. Soft-tissue reconstruction of an overlapping toe is a typical reason to report 28313, when the documented correction does not include bone work.

How should the number of toes be documented?

Identify each corrected toe and describe its deformity and the soft-tissue work performed. The code is reported for each toe corrected.

Can modifier 50 be used when both feet are treated?

No. CMS identifies bilateral adjustment as inappropriate for 28313. Modifier 50 should not be appended.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

How does Medicare handle other procedures in the same session?

The highest-valued procedure is paid in full, and other procedures in the session are subject to the standard multiple-procedure reduction. Medicare does not pay an assistant at surgery; 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.
