About 23921: Secondary closure after shoulder disarticulation
Reports delayed surgical closure of an open shoulder-disarticulation wound when the stump is closed in a separate operative session.
This service closes a shoulder-disarticulation wound that was left open and requires closure in a later operative session. The surgeon prepares the existing amputation wound and brings the tissue together to complete stump closure. It is distinct from performing the shoulder disarticulation itself. The procedure may arise after an amputation wound was intentionally left open or could not be closed at the initial operation; the operative report should establish that this is secondary closure of the shoulder-disarticulation site.
Report this code for the delayed closure, not for the initial disarticulation or routine wound care. The code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. For bilateral surgery, modifier 50 is paid at 150%. Assistant-at-surgery services are not paid; co-surgeons and team surgery are not permitted.

23921 billing questions
How is this different from the shoulder disarticulation code?
This code is for closing the shoulder-disarticulation wound in a later operative session. The shoulder disarticulation code describes creating the amputation, not its delayed closure.
What documentation supports reporting this service?
The operative report should identify the prior shoulder disarticulation site, explain that the wound remained open, and describe the surgical steps used to close it.
Can routine postoperative wound care be reported separately?
Related postoperative care is included in the 90-day global period. This code describes the operative secondary closure, not routine care during recovery.
How are additional procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple procedure reduction, with payment at 50%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery services are not paid for this code. Co-surgeons and team surgery are not permitted.
How should bilateral closure be reported?
For bilateral surgery, report modifier 50; CMS pays the bilateral procedure at 150%.
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.
