What 45384 covers
During flexible colonoscopy, the endoscopist removes a polyp or other lesion using hot biopsy forceps or bipolar cautery. Gastroenterologists and colorectal surgeons commonly perform this in an endoscopy center or hospital outpatient department; it may also be performed in an appropriately equipped office. For example, a polyp treated with cautery during the examination is reported by the removal method, not as a diagnostic-only examination.
Select this code when the documented removal technique is hot biopsy forceps or bipolar cautery; a snare removal is reported with a different code. The procedure note should identify the lesion and document the technique used. The diagnostic examination is part of the therapeutic colonoscopy, rather than a separate diagnostic service for that same examination. This minor procedure has a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, CMS endoscopy family pricing applies. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service, and co-surgeon and team-surgery billing are not permitted.

How to choose
- 45385Snare polypectomyDuring colonoscopy
- 45384 is for removal with hot biopsy forceps or bipolar cautery; 45385 is for removal by snare.
- 45380Colonoscopy with biopsySingle or multiple forceps biopsies
- 45380 reports colonoscopic biopsy sampling. Choose 45384 when the lesion is removed using hot biopsy forceps or bipolar cautery.
- 45390ColonoscopyMucosal lesion resection
- 45390 is used for endoscopic resection rather than the cautery removal technique represented by 45384.
- 45378ColonoscopyDiagnostic, no tissue removal
- 45378 describes a diagnostic colonoscopy without therapeutic lesion removal; when the examination includes removal under 45384, the diagnostic inspection is included.
45384 billing questions
When should 45384 be chosen over 45385?
Use 45384 when the lesion is removed with hot biopsy forceps or bipolar cautery. Use 45385 when the documented removal method is a snare.
Can the diagnostic colonoscopy also be reported?
The diagnostic inspection is included when the colonoscopy proceeds to lesion removal during the same examination. Do not separately report 45378 for that same examination.
How does 45384 differ from a colonoscopy biopsy?
45384 represents lesion removal by cautery technique. Use 45380 when the service is tissue sampling by biopsy rather than removal using the 45384 technique.
What documentation supports reporting 45384?
The procedure note should identify the lesion and state that hot biopsy forceps or bipolar cautery was used to remove it. The documented technique distinguishes this code from snare removal.
Can an assistant surgeon or co-surgeon be reported?
Medicare does not pay an assistant at surgery for this service. Co-surgeon and team-surgery billing 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.
