What 28220 covers

This operation frees a single flexor or extensor tendon in the foot from restrictive scar tissue or adhesions that limit its movement. An orthopedic or podiatric surgeon typically performs it in an operating room, often when motion remains restricted after trauma or a prior procedure. The operative work addresses tendon glide by releasing surrounding adhesions; it is distinct from repairing a torn tendon or cutting a tendon to change its function.

Report this code when the operative record identifies the treated foot tendon and documents adhesion release involving one tendon. Distinguish it from codes for multiple-tendon release and tendon repair by the structures treated and the work performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For same-session procedures, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery services are not paid; 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.

28220 billing questions

When is this code appropriate instead of a tendon repair code?

Use it for release of adhesions restricting one foot tendon, rather than repair of a tendon injury. The operative note should support adhesion release as the work performed.

How does this differ from 28222?

28220 describes release involving a single tendon. 28222 is the nearby multiple-tendon release code.

What should the operative note document?

Identify the foot tendon treated and describe the adhesions and their release. The record should make clear that the work involved one tendon, not tendon repair or a different type of release.

How is bilateral reporting paid?

CMS lists this as a bilateral procedure. Reporting modifier 50 results in payment at 150%.

Are assistant-at-surgery or co-surgeon services payable?

CMS lists a statutory restriction on assistant-at-surgery payment for this code. Co-surgeons and team surgery are not permitted.

What happens when another procedure is performed in the same session?

Under the standard multiple-procedure rule, the highest-valued procedure is paid in full and other procedures are paid at 50%.

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.
