Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 25240 covers

This service removes a limited amount of ulnar bone, often near the wrist, to address painful contact between the ulna and carpal bones or to correct positive ulnar variance. A hand or orthopedic surgeon may perform the procedure as an open operation or, for a wafer resection, arthroscopically. The operative report should identify the treated side, the portion and amount of bone removed, the technique, and the clinical reason for resection.

Select this code when the documented procedure is a partial ulna ostectomy; distinguish it from removal of the radius, carpal bones, or a shortening osteotomy. The CMS global period 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 others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery and co-surgeon payment require supporting documentation, with medical necessity documented for an assistant. Team surgery is not permitted.
