What 28225 covers

This service involves freeing a flexor tendon in the foot when restricted glide interferes with movement. An orthopedic foot and ankle surgeon or podiatric surgeon may perform it in an operating room or other surgical setting, often for a tendon that remains tethered after prior surgery or injury. The operative work releases the tendon rather than repairing or grafting a damaged tendon or cutting it as a tenotomy.

Report the code when the operative note identifies the flexor tendon released, the foot and side treated, and the clinical restriction that prompted the procedure. This major surgery has a 90-day global period that includes the day-before preoperative visit and 90 days of related postoperative care. For other procedures performed in the same session, the highest-valued procedure is paid in full and additional procedures are paid at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons are paid only with supporting documentation, and team surgery is 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.

28225 billing questions

How is this different from a foot tendon tenotomy?

This code describes freeing a restricted flexor tendon. Tenotomy codes describe cutting or incising a tendon, rather than releasing adhesions to restore its glide.

What should the operative note identify?

Document the flexor tendon released, the foot and laterality, the reason its movement was restricted, and the release performed.

Does the 90-day global period include postoperative visits?

Yes. Related postoperative care for 90 days and the day-before preoperative visit are included in the global period.

How is bilateral treatment reported?

When the procedure is performed on both feet, modifier 50 identifies the bilateral service; CMS pays it at 150%.

Can an assistant or co-surgeon be paid?

Assistant-at-surgery payment is restricted. Co-surgeons are paid only when supporting documentation is provided.

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.
