What 45330 covers

A physician, commonly a gastroenterologist or colorectal surgeon, advances a flexible endoscope through the anus to inspect the rectum and sigmoid colon. The service is used to evaluate concerns such as rectal bleeding, altered bowel habits, or suspected distal-colon disease. Specimens collected by brushing or washing are included when performed; the code represents a diagnostic examination, not a tissue biopsy or lesion treatment.

Report 45330 when the examination is diagnostic and no separately coded intervention is performed. The report should support the indication, the portion of bowel examined, and the findings; document any brushing or washing when performed. This minor procedure has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued is paid in full and the others at 50%. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

45330 billing questions

When should 45330 be reported instead of 45331?

Use 45330 for a diagnostic examination without tissue biopsy. When the physician obtains a biopsy during flexible sigmoidoscopy, report the biopsy service, 45331, rather than the diagnostic-only code.

Are brushing and washing separately billable?

No. Specimen collection by brushing or washing is included in 45330 when performed. A tissue biopsy or therapeutic maneuver is a different service.

Can 45330 be billed with a polypectomy code for the same examination?

When the same sigmoidoscopy includes polyp removal, report the applicable intervention code rather than separately reporting the diagnostic examination as 45330.

Should modifier 50 be appended for examination of both sides?

No. Bilateral adjustment does not apply to this code, and modifier 50 is inappropriate for the sigmoidoscopy service.

How does the multiple-procedure rule affect payment?

For procedures performed in the same session, Medicare pays the highest-valued procedure in full and pays the other procedures at 50%.

What documentation supports 45330?

Document the diagnostic reason, scope examination and extent, findings, and any brushing or washing. If biopsy or treatment is performed, document that work and report the applicable procedure code.

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.
