About G0455: Fecal microbiota preparation and instillation
Reports preparation and delivery of fecal microbiota, commonly for selected patients with recurrent Clostridioides difficile infection.
G0455 covers preparing fecal microbiota and instilling it into the patient by a delivery method such as colonoscopy, upper gastrointestinal access, or enema. Gastroenterologists commonly provide the service for selected patients with recurrent Clostridioides difficile infection. The code represents the microbiota preparation and delivery, not the colonoscopy or upper endoscopy used to reach the treatment site.
Report G0455 when both preparation and instillation are performed; document the clinical indication, preparation, delivery method, and procedure performed. The code has a 0-day global period, so same-day preoperative and postoperative care is included. Modifier 50 is inappropriate for this service. An assistant at surgery is payable only when medical necessity is documented; co-surgeons and team surgery are not permitted.

G0455 billing questions
How does G0455 differ from CPT 44705?
G0455 covers preparation and instillation of fecal microbiota. CPT 44705 describes preparation for instillation, so distinguish the services by whether the microbiota is also delivered.
Can the endoscopic procedure be reported separately?
G0455 describes microbiota preparation and delivery, not the endoscopic access procedure. When a separately reportable colonoscopy or upper endoscopy is performed, report that procedure under its applicable code.
Should modifier 50 be appended for bilateral delivery?
No. CMS identifies bilateral adjustment as inappropriate for G0455.
Can an assistant, co-surgeon, or surgical team be reported?
An assistant at surgery is payable only with documentation of medical necessity. Co-surgeons and team surgery are not permitted for this code.
What care is included in the global period?
G0455 has a 0-day global period. Same-day preoperative and postoperative care is included.
