What 44121 covers

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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

44121 billing questions

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.
