What 45338 covers

A clinician advances a flexible scope through the rectum to examine the distal colon and uses a snare to remove a lesion, such as a polyp found in the sigmoid colon. Gastroenterologists and colorectal surgeons commonly perform the procedure in an endoscopy unit or hospital outpatient department. The removed tissue may be submitted for pathologic examination. This code reflects snare removal, not a procedure limited to inspecting the bowel or sampling tissue with biopsy forceps.

Report the service when the procedure record supports flexible sigmoidoscopy and snare removal; document the lesion site and removal technique. The 0-day global period includes same-day preoperative and postoperative care. When related endoscopies are performed together, CMS endoscopy family pricing applies. 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.

45338 billing questions

How is this different from 45333?

Use 45338 for snare removal. Code 45333 describes removal using hot biopsy forceps or bipolar cautery.

Can this be reported for a biopsy alone?

No. A biopsy without snare removal is represented by the biopsy service, such as 45331.

Should the code be billed once for each polyp?

The service is the snare-removal procedure, not a per-polyp unit. Document the lesions treated and the technique used.

What happens when another related endoscopy is performed in the same session?

CMS endoscopy family pricing applies when related endoscopies are performed together; payment is not treated as unrelated procedures.

Is modifier 50 appropriate, or can an assistant be paid?

Modifier 50 is inappropriate for this anatomy. Medicare does not pay an assistant at surgery for this code.

What does the 0-day global period include?

Same-day preoperative and postoperative care is included in the procedure's global period.

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.
