G0121 - Colonoscopy screening for colon cancer in average-risk individuals
Healthcare Common Procedure Coding System
What is a HCPCS Code?
HCPCS (Healthcare Common Procedure Coding System) codes are used to identify medical procedures, supplies, and services for billing purposes. These codes help standardize how healthcare services are reported and billed across different providers and insurance companies.
Detailed Description
This code represents a colonoscopy procedure performed specifically to screen for colorectal (colon and rectal) cancer in individuals who are considered average risk. This means the patient does not have factors that would classify them as high risk for developing colorectal cancer, such as a strong family history, personal history of polyps or inflammatory bowel disease, or certain genetic conditions. The colonoscopy is done as a preventive measure to detect cancer or precancerous changes early, when treatment is most effective.
Additional Information
This is specifically for screening purposes in average-risk patients. Different codes may apply for high-risk patients or diagnostic procedures.
