What 45308 covers

A rigid proctosigmoidoscope is used to inspect the rectum and distal sigmoid and remove a tumor, polyp, or other lesion with hot biopsy forceps or bipolar cautery. Gastroenterologists and colorectal surgeons may perform the procedure in an office, endoscopy suite, or operating room. The operative note should identify the rigid scope, the lesion treated, and the removal technique; a diagnostic examination or tissue sampling alone does not establish this service.

Select this code for cautery removal, rather than snare removal or biopsy alone. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, endoscopy-family pricing applies. Modifier 50 is inappropriate for this anatomy and service. Medicare does not pay an assistant at surgery, and co-surgeon and team-surgery billing 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.

45308 billing questions

How does this differ from 45309?

This code represents lesion removal with hot biopsy forceps or bipolar cautery. Code 45309 is the related rigid-scope option when the lesion is removed by snare.

Can I report this for a biopsy?

No. Biopsy without the described cautery removal is represented by 45305 for rigid proctosigmoidoscopy.

Can diagnostic endoscopy be separately reported with this service?

When related endoscopies are performed together, CMS endoscopy-family pricing applies. The procedure documentation should support the therapeutic service and any separately reported endoscopy.

Should modifier 50 be appended for multiple lesions or sides?

No. Modifier 50 is inappropriate for this service and anatomy; the CMS bilateral adjustment does not apply.

Can an assistant or co-surgeon be billed?

Medicare does not pay an assistant at surgery for this code. Co-surgeon and team-surgery billing are not permitted.

What is included in the 0-day global period?

Same-day preoperative and postoperative care is included. The global period is 0 days.

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.
