Colonoscopy
About 44388: Diagnostic colonoscopy through a stoma
Reports diagnostic examination of the colon using a scope passed through a stoma, when no separately coded therapeutic intervention defines the service.
A gastroenterologist or colorectal surgeon passes a colonoscope through a colostomy stoma to examine the colon. This approach is used when the patient’s anatomy or the clinical plan calls for examination through the stoma rather than through the anus. The service may be performed in an office or a facility. The report should identify the stoma access, the portion of colon examined, findings, and any sampling or treatment performed.
Select this diagnostic code when the examination is performed without a separately coded therapeutic intervention. If the endoscopist biopsies tissue, removes a foreign body or lesion, or treats bleeding, use the code describing that work instead. Medicare assigns a 0-day global period, so same-day preoperative and postoperative care is included. Modifier 53 is separately priced in CMS data for a discontinued procedure. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction. Medicare does not pay assistant-at-surgery services for this code; co-surgeon and team-surgery services are not permitted.

44388 billing questions
When should the diagnostic code be replaced by a therapeutic code?
Use a code for the intervention when the endoscopist biopsies tissue, removes a foreign body or lesion, or treats bleeding through the stoma. The diagnostic examination is not separately reported as the defining service for that therapeutic work.
How is this different from colonoscopy through the anus?
This code describes scope access through a stoma. A colonoscopy performed through the anus is coded from the applicable non-stoma colonoscopy family.
Does this code cover examination of an ileal pouch?
No. Pouch endoscopy is reported with the pouch-specific code family, such as 44385, rather than this colonoscopy-through-stoma code.
How should modifier 53 be handled?
CMS lists modifier 53 as separately priced for this code. It identifies a discontinued procedure; the record should explain why the examination was stopped.
What happens when other procedures are performed in the same session?
The highest-valued procedure is paid in full, and the other procedures are subject to the standard multiple-procedure reduction. The code has a 0-day global period, which includes same-day preoperative and postoperative care.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
