What 28222 covers

28222 represents surgical freeing of adhesions that tether one extensor tendon in the foot and limit its movement. An orthopedic foot and ankle surgeon or podiatric surgeon may perform it when scarring after an injury or prior tendon procedure restricts tendon glide. The operative work addresses the adhesions around the tendon; it is not tendon division or tendon repair.

Choose this code for one extensor tendon. Documentation should identify the tendon and foot, describe the adhesions and restricted glide, and record the release performed. The multiple-tendon extensor service is 28226; flexor tendon services are coded separately by tendon type and count. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. 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.

28222 billing questions

When is 28222 appropriate instead of 28226?

Use 28222 when adhesiolysis involves one foot extensor tendon. 28226 is the corresponding service for multiple extensor tendons.

How does this differ from an extensor tenotomy?

28222 frees a tendon from adhesions while preserving tendon continuity. A tenotomy code describes cutting the tendon, not freeing it from scar tissue.

What should the operative note identify?

Document the foot and specific extensor tendon, the adhesions restricting its movement, and the surgical release performed.

Can modifier 50 be used when both feet are treated?

CMS identifies this as a bilateral procedure; reporting with modifier 50 is paid at 150%.

Is postoperative care separately included in the service?

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

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.
