What 44380 covers

Code 44380 reports diagnostic inspection of the ileum by passing an endoscope through an existing ileostomy. Gastroenterologists and colorectal surgeons may use it to evaluate symptoms such as bleeding or pain, or suspected ileal inflammation, in a patient with a stoma. Collection of cells or fluid by brushing or washing may be part of the examination. This code is not for an examination that includes tissue biopsy or a therapeutic maneuver, and it is distinct from examination of an ileal pouch or colonoscopy through a stoma.

Document the stoma route, the ileal examination, the clinical indication, and any brushing or washing performed. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures occur in one session, Medicare pays the highest-valued procedure in full and applies the standard reduction to the others. 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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

44380 billing questions

When should 44380 be reported instead of 44381?

Use 44380 for diagnostic ileoscopy through a stoma when no tissue biopsy is performed. When the examination includes biopsy, use 44381.

Are brushing and washing included?

Yes. Collection of specimens by brushing or washing is included when performed during the diagnostic examination.

Does this code describe an examination of an ileal pouch?

No. Code 44380 is for ileoscopy through a stoma; ileal pouch endoscopy is represented by a different code family, including 44385 and 44386.

Should modifier 50 be appended for a bilateral examination?

No. The anatomy and descriptor make modifier 50 inappropriate for this service.

How does Medicare handle other procedures performed in the same session?

Medicare pays the highest-valued procedure in full and applies the standard multiple procedure reduction to the others. The 0-day global period includes same-day preoperative and postoperative care.

Can an assistant, co-surgeon, or surgical team be reported?

Medicare does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
