About 26508: Surgical release of thumb contracture

Surgical release of a fixed thumb contracture, reported when shortened soft tissue restricts thumb position or motion and requires operative correction.

This service surgically releases shortened tissue that holds the thumb in a restricted position, such as a scar-related limitation of thumb opening or opposition. It is typically performed by a hand, orthopedic, or plastic surgeon when the restriction causes functional impairment and needs operative correction. The operative report should identify the affected thumb, the contracture and its effect on motion or function, and the tissue released.

Report the code for the thumb contracture release itself, distinguishing it from a finger or knuckle contracture release and from a tendon transfer. The major-surgery 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 at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.

26508 billing questions

How does this differ from 26520 or 26525?

Use 26508 for a contracture of the thumb. Codes 26520 and 26525 address contractures at a knuckle joint or in a finger, respectively.

Is this the right code for a thumb tendon transfer?

No. This code represents release of contracted tissue; 26510 describes a thumb tendon transfer, which changes tendon mechanics rather than releasing the contracture.

What documentation supports reporting this code?

Document the thumb contracture, its effect on motion or function, the operative release performed, and the side treated.

How is bilateral treatment reported?

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

Can an assistant surgeon be reported?

Assistant-at-surgery payment is allowed only when the record documents medical necessity. Co-surgeons and team surgery are not permitted.

What happens when another procedure is performed in the same session?

CMS pays the highest-valued procedure in full and other procedures at 50% under the standard multiple procedure reduction.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
