About 44121: Additional small bowel resection with anastomosis
Reports an additional small-intestine segment resection with anastomosis performed during an operative session that includes the primary resection.
This add-on describes another small-intestine segment resection with an anastomosis during the same operative session as the primary resection. A surgeon may perform it when separate diseased segments require individual removal and reconnection, such as in a patient with more than one affected area of bowel. It distinguishes an additional resection and anastomosis from simply removing a longer continuous segment.
Report 44121 with the applicable primary procedure, not by itself. The operative report should establish that an additional segment was resected and anastomosed, beyond the resection represented by the primary code. CMS treats this as an add-on code: payment is handled within the primary procedure’s global period. The primary procedure and the additional work should be identifiable in the operative documentation.

44121 billing questions
When is 44121 reported with 44120?
Use 44121 for an additional small-intestine resection and anastomosis beyond the primary resection reported with 44120. The additional work must be documented in the operative report.
Can 44121 be billed by itself?
No. It is an add-on code and must be reported with an applicable primary procedure.
Does a longer single resection support 44121?
Not by itself. The documentation should show another resection and anastomosis, rather than only a longer continuous segment removed as part of the primary resection.
How does 44121 differ from 44125?
44121 represents an additional resection with anastomosis. 44125 describes a small-intestine resection with an enterostomy, a different reconstruction.
How is 44121 paid in relation to the primary procedure?
CMS identifies it as an add-on code paid within the primary procedure’s global period. It cannot be reported without the primary procedure.
