What 26390 covers
A hand surgeon revises a tendon in the hand or finger when prior tendon surgery has left a problem requiring operative correction. The service may be performed by an orthopedic or plastic surgeon in an operating room. The operative record should identify the affected tendon and site, the prior procedure or condition prompting revision, and the corrective work actually performed. This code describes revision, not simply a new primary tendon repair or treatment of restricted movement by manipulation.
Report the code when the surgeon performs revision of the hand or finger tendon; distinguish it from a repair performed as the primary procedure and from tendon release for adhesions. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this code. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

26390 billing questions
How is revision different from a primary tendon repair?
Use revision when the operation corrects a problem involving a previously treated tendon. A primary repair code describes a tendon repair performed as the primary procedure rather than revision of prior work.
Is tendon adhesions release the same service?
No. Tenolysis frees a tendon restricted by adhesions; report revision when the surgeon performs corrective surgery on the tendon itself rather than only releasing adhesions.
Does this code have a 90-day global period?
Yes. The global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can modifier 50 be used for both hands or fingers?
No. CMS identifies bilateral adjustment as inappropriate for this code; modifier 50 should not be used.
When can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.
