What 49429 covers

This service removes a peritoneovenous shunt that carries fluid from the abdominal cavity into the venous circulation. It may be performed when the device is no longer needed or requires removal; the operative note should identify the shunt and document the removal performed. A surgeon typically carries out the procedure in a hospital operating room or another surgical setting. It is distinct from simply closing off the shunt while leaving it in place.

Report this code for removal, not for shunt insertion, revision, or ligation alone. Documentation should support that the shunt was removed and describe the work performed. Medicare assigns a 10-day global period, including related postoperative visits during that period. 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 50% reduction. Modifier 50 is inappropriate for this anatomy. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.
