What 43848 covers

A bariatric surgeon uses an open approach to revise a prior gastric restrictive operation, such as a gastric bypass. The work may involve changing the existing gastric anatomy or revising its gastrojejunal connection as part of the bariatric revision. These operations are typically performed in a hospital operating room for patients whose existing bariatric anatomy requires surgical revision.

Report this code for revision of the prior restrictive procedure, not for creating a new bypass or revising only an access port. The operative report should identify the prior procedure, the anatomy revised, and the work performed. Medicare includes the day-before preoperative visit and 90 days of related postoperative care in the major-surgery global period. 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. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted. Report one service for the single operative anatomy rather than a bilateral service.

Can the gastrojejunal anastomosis revision be reported separately?

Revision of the gastrojejunal anastomosis is included when it is part of the gastric restrictive procedure revision reported with 43848. The operative note should make clear whether the anastomotic work is part of that revision.
