Frequently Asked Questions
CPT 45330 reports a diagnostic flexible sigmoidoscopy, an exam of the rectum and lower colon with a flexible scope, including collection of specimens by brushing or washing when performed.
A sigmoidoscopy with biopsy is reported with 45331 instead of 45330. Polyp removal and other therapeutic work have their own codes. CPT 45330 has a 0-day global period.
Medicare pays CPT 45330 under the Physician Fee Schedule. The non-facility rate applies when the service is done in an office and covers the practice's staff, supplies and equipment; the lower facility rate applies in a hospital or surgery center, which bills its own facility fee. Both are adjusted for the local cost of practice. Commercial payers negotiate their own rates, often as a percentage of Medicare, so the same code can pay very differently from one contract to the next.
This page lists the rates commercial payers have published for CPT 45330 in their Transparency in Coverage files, so you can compare payers and see where a contract falls. For government benchmarks, PayerPrice also has the Medicare fee schedule lookup and Medicaid fee schedules by state.
