Hand surgery
About 26591: Intrinsic muscle repair of the hand
Reports operative repair of injured intrinsic hand muscles, such as interossei or lumbricals, when the procedure restores the muscle’s continuity or function.
This code covers surgical repair of intrinsic muscles within the hand, including muscles such as the interossei and lumbricals. A hand surgeon or other qualified surgical specialist may perform the repair for a disrupted muscle, such as after a hand injury. The service is generally performed in an operating room; the operative report should identify the injured muscle and describe the repair performed.
Report the code for the intrinsic muscle repair itself, not for a repair directed at a joint or a release of tight intrinsic muscles. Document the affected anatomy, side, and operative work so the service can be distinguished from those procedures. Medicare assigns a 90-day global period, including 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 multiple-procedure reduction. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.

26591 billing questions
How is this code different from 26593?
26591 reports repair of an intrinsic hand muscle. 26593 is for releasing intrinsic muscles when tightness or contracture is the operative problem.
Can this code be used for a hand joint repair?
No. Use a joint-repair code, such as 26540 when its service applies, for repair directed at the hand joint rather than the intrinsic muscle.
Should modifier 50 be appended for repairs on both hands?
No. CMS identifies bilateral adjustment as inappropriate for this code’s descriptor or anatomy.
What documentation supports reporting 26591?
The operative report should identify the intrinsic muscle repaired, the side, the injury or disruption addressed, and the repair performed.
How are other procedures in the same session paid?
Under the standard multiple-procedure rule, the highest-valued procedure is paid in full and other procedures are subject to a 50% reduction.
Can an assistant surgeon or co-surgeon be reported?
Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted for this code.
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.
