What is a Colonoscopy?
During a colonoscopy, a gastroenterologist inserts a flexible tube with a camera into your rectum to examine your entire colon. The procedure can detect polyps, cancer, and other abnormalities. Polyps found during the exam can be removed immediately.

Insurance Tips for Colonoscopy
Screening colonoscopies are covered 100% under the ACA with no cost-sharing for most plans. However, if polyps are removed, the procedure may be reclassified as "diagnostic," potentially triggering your deductible. Always confirm coverage with your insurer before scheduling.
Before Scheduling, Ask:
- 1.Is this facility in my insurance network?
- 2.Does this procedure require prior authorization?
- 3.What is my out-of-pocket cost after deductible?
- 4.Is there a cash-pay discount if I pay upfront?
When Do You Need a Colonoscopy?
The American Cancer Society recommends regular colorectal screening starting at age 45 for average-risk adults. You may need earlier or more frequent screening if you have family history of colon cancer, inflammatory bowel disease, or previous polyps.
