What 45380 covers

The endoscopist advances a flexible colonoscope through the rectum and colon, typically to the cecum, and uses biopsy forceps to sample mucosa or lesions. Common indications include suspected inflammatory bowel disease, chronic diarrhea with random biopsies for microscopic colitis, and evaluation of a mass. Small polyps removed with cold biopsy forceps are also reported with 45380. Gastroenterologists and general or colorectal surgeons perform the procedure, mostly in hospital outpatient departments and ambulatory surgery centers, with a smaller share in offices.

Report one unit per colonoscopy session regardless of the number of biopsies or sites sampled; document the sites and extent reached. Diagnostic colonoscopy 45378 is included and is not billed separately. When related colonoscopy procedures are reported together, endoscopy family pricing pays the highest-valued procedure in full and reduces each additional procedure by the family's base endoscopy value. The 0-day global includes routine same-day preoperative and postoperative care. Assistant-at-surgery payment is statutorily restricted; co-surgeons and team surgery are not permitted. Modifier 50 is inappropriate. Append modifier PT when a Medicare screening colonoscopy leads to biopsy.

45380 billing questions

How many units are reported when several biopsies are taken from different segments?

One unit. The code covers single or multiple biopsies during the same colonoscopy, so random biopsies from the ascending, transverse, and sigmoid colon are still a single line.

Can 45380 be billed with snare polypectomy 45385 in the same session?

Yes, when the biopsy is of a different lesion than the one removed by snare. Append modifier 59 or XS to 45380 and document separate lesions; biopsy of the same lesion before snaring is not separately reported.

Which code applies when a small polyp is removed with cold biopsy forceps?

Cold forceps removal is reported with 45380. Hot biopsy forceps removal goes to 45384, and snare removal, hot or cold, goes to 45385.

What modifier is needed when a Medicare screening colonoscopy turns into a biopsy?

Report 45380 with modifier PT to identify the procedure as a screening colonoscopy converted to biopsy. The Medicare Part B deductible is waived.

Is the pathology work included in 45380?

No. The endoscopist's code covers obtaining the tissue only; the pathologist separately reports the specimen examination, commonly with 88305 for each separately submitted specimen.

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.
