Flexible Sigmoidoscopy With Biopsy

Washington, DC rates for HCPCS 45331

In this exam, a thin, flexible, lighted scope is passed through the rectum into the lower part of the colon, and the physician takes one or more tissue samples from the lining for laboratory examination. Biopsies can help diagnose conditions such as inflammation, infection, or precancerous or cancerous changes found during the exam. It examines only the lower portion of the colon rather than the entire length, which a full colonoscopy would cover.
