About 44346: Colostomy revision with hernia repair
Reports operative revision of an existing colostomy performed with repair of a parastomal hernia, rather than revision alone or new colostomy creation.
This code covers surgery that revises an existing colostomy and repairs the parastomal hernia around it. A colorectal or general surgeon may perform the operation when the hernia and stoma require operative correction, such as when the hernia interferes with pouching or causes symptoms. The service is generally performed in a hospital operating room, not as an office stoma adjustment.
Report the code when the operative work includes both colostomy revision and repair of the parastomal hernia. The operative report should document the existing colostomy, the hernia, and the work performed to revise the stoma and repair the hernia. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

44346 billing questions
How does this differ from 44340 or 44345?
Use 44346 when the colostomy revision is performed with repair of a parastomal hernia. Codes 44340 and 44345 describe colostomy revisions without that hernia-repair distinction.
Can the hernia repair be reported separately?
The defining work for 44346 includes repair of the parastomal hernia along with colostomy revision. The operative report should support both parts of that service.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care for the operation.
Can an assistant surgeon be reported?
CMS permits payment for an assistant at surgery for this code. Co-surgeon payment requires supporting documentation.
How are other 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.
