What 28238 covers

CPT 28238 covers operative revision of a tendon in the foot. An orthopedic foot-and-ankle surgeon or podiatric surgeon may perform the procedure when the tendon requires revision after prior treatment. The specific tendon, side, and operative approach depend on the patient’s condition and the surgeon’s findings. The operative report should make clear that the work is a revision of the foot tendon, not simply a new primary repair or a tendon release.

Select the code based on the procedure actually performed and documented. Identify the affected tendon and side, the reason for revision, and the revision work in the operative report. This major surgery has a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in one 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%. Assistant-at-surgery payment may be made; co-surgeon payment requires 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.

28238 billing questions

How does 28238 differ from a foot tendon repair code?

Use 28238 for a documented revision of a foot tendon. Codes such as 28200 or 28208 describe tendon repair services, with the code choice depending on the tendon and repair details.

Can tendon release or adhesion work be reported as 28238?

Choose the code for the work actually performed. A tendon release or adhesion procedure is distinct from revising the tendon itself.

What postoperative care is included?

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

How is 28238 paid when other 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 at 50%.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.

How should bilateral surgery be reported?

For bilateral surgery, report modifier 50; CMS pays the bilateral procedure at 150%.

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.
