What 45385 covers

During this procedure, a gastroenterologist or colorectal surgeon advances a flexible colonoscope through the colon, typically to the cecum. Polyps or other lesions are captured with a wire snare and removed either cold or with electrocautery. Removed tissue is typically submitted for pathology. Most cases occur in hospital outpatient departments and ambulatory surgery centers, with a smaller share in office endoscopy suites. Common situations include screening colonoscopies that uncover adenomas, surveillance after prior polyps, and evaluation of a positive stool test.

Report one unit per session regardless of how many lesions are snared. The procedure report should identify the removal technique, lesion sites and sizes, exam extent, and bowel prep quality. The 0-day global period includes same-day preoperative and postoperative care. When related endoscopies are performed together, endoscopy family pricing uses diagnostic colonoscopy 45378 as the base to calculate payment for additional procedures. Medicare does not pay an assistant at surgery for 45385; co-surgeons and team surgery are not permitted. Because the colon is not a bilateral structure, modifier 50 is inappropriate.

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.

45385 billing questions

How many units are reported when several polyps are removed by snare?

One unit. The code covers all lesions removed by snare during the session, regardless of their number or location.

Can 45380 be reported with 45385 in the same session?

Yes, when a separate lesion is biopsied. Use modifier 59 on 45380 when needed to identify the distinct lesion; a biopsy of the lesion subsequently removed by snare is included in 45385.

What happens when a Medicare screening colonoscopy turns into a polypectomy?

Report 45385 instead of the screening G code and append modifier PT to identify the procedure as a screening that became therapeutic. The Medicare screening-related deductible waiver then applies.

Should 45385 or 45390 be reported when a polyp is lifted with an injection before snaring?

An injection lift alone does not establish endoscopic mucosal resection. Report 45390 when the procedure report supports that resection technique; do not add 45385 or 45381 for the same lesion's resection and lift.

Can a tattoo injection be added to 45385?

A documented submucosal ink injection to mark the polypectomy site may be reported with 45381. When both services are payable, endoscopy family pricing applies.

How do snare and hot biopsy forceps removal differ for coding?

Snare removal, hot or cold, is reported with 45385. Removal with hot biopsy forceps or bipolar cautery is reported with 45384; when different lesions are treated by both methods, a distinct-procedure modifier may be needed.

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.
