What 28234 covers

The surgeon makes an incision to expose and divide a single extensor tendon in the foot or toe. This may be performed by an orthopedic or podiatric surgeon to reduce tendon pull contributing to a deformity or contracture. The procedure is distinct from freeing a tendon from adhesions and from repairing a damaged tendon. It is typically performed in an operating room or outpatient surgical setting.

Report the code for one extensor tendon divided through an open approach; document the tendon and site, the clinical problem, and the work performed. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. 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 50% multiple-procedure reduction. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery, and 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.

Can code 28234 be reported with hammertoe correction?

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.
