About 49400: Peritoneography by Air Injection
Peritoneography reports injection of air or contrast into the peritoneal cavity to create an imageable study of the abdominal cavity.
Peritoneography creates an imageable outline of the peritoneal cavity by introducing air or contrast, with imaging guidance when performed. A radiologist or other physician performs the injection in a procedural or imaging setting to investigate a clinical question involving the peritoneal cavity. The target is the general peritoneal space, not a localized cyst or fluid collection and not a site being treated with a drainage catheter.
Report the service when the documented procedure injects material into the peritoneal cavity for peritoneographic imaging; documentation should identify the injection and the imaging purpose. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted.

What documentation supports reporting 49400?
Document the injection into the peritoneal cavity, the injected material, and the purpose of obtaining peritoneographic imaging. Distinguish the general peritoneal space from a localized fluid collection.
How does the multiple-procedure rule affect payment?
When 49400 is performed with other procedures in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction.
