Under the Affordable Care Act, certain preventive health care tests, which can help find or prevent serious diseases or health problems, are free to patients, including colorectal cancer screening. Colonoscopy is one of these tests and while it is often free, there are some times when a coinsurance payment is required.
The good news — new policies are making colorectal cancer screening free to more people and getting rid of surprise bills.
Read this guide to learn what to expect and what to do if you get a bill you were not expecting after having a colorectal cancer screening.
Here are the most common screening tests, how often they’re needed, and what you can usually expect to pay depending on whether you have commercial (private) health insurance or Medicare (government health insurance program; coverage may be dependent on whether you have original Medicare or Medicare Advantage).

- Non-invasive test for people at average risk for colon cancer [no family history, gastrointestinal (GI) symptoms or inflammatory bowel disease (IBD), including Crohn’s disease or ulcerative colitis], like fecal immunochemical testing (FIT) or a multi-targeted stool DNA test (like Cologuard®).*
- Done every 1-3 years (depending on the type of test) starting at age 45 to look for DNA changes and small amounts of blood in the stool that could come from colon cancer or pre-cancerous polyps. A colonoscopy is needed if the stool test is positive.
- Commercial insurance: Pays for both the stool-based test and colonoscopy (including polyp removal) after a positive stool test if it was done after May 31, 2022. For tests performed before May 31, 2022, the stool-based test is covered at 100%, but you might have to pay some of the costs for the colonoscopy.
- Medicare: Pays for both the stool-based test and colonoscopy at no cost, but you may have to pay some of the cost of the colonoscopy if you have polyp(s) removed.
- Procedure for people at average risk for colon cancer.
- Done every 10 years starting at age 45 to look for (and remove, if needed) colon polyps in patients who do not have any symptoms, such as bleeding, gut pain or diarrhea.
- Commercial insurance: Costs for your colonoscopy, bowel prep, sedation (medicine to put you to sleep), lab work, and the hospital or ambulatory surgery center where the colonoscopy was done are covered 100% by health insurance even if polyps are removed.
- Medicare: Colonoscopy and sedation are covered 100% when no polyps are found. In 2022, if a polyp is taken out you are responsible for 20% of the cost. From 2023 to 2026, your responsibility is 15% of the cost, from 2027 to 2029 it falls to 10%, and by 2030 it will be covered 100% by Medicare.
- Procedure for people at higher risk for colon cancer or with certain GI symptoms.
- Done to look for inflammation, or swelling, in patients who have IBD, bleeding, or other GI symptoms, such as rectal bleeding or blood in the stool (bright red, black or very dark), gut pain, or diarrhea.
- Not fully covered by Medicare or commercial insurance, meaning you may have to pay some of the costs, including those for the bowel prep, sedation, lab work, and the hospital or ambulatory surgery center costs where the colonoscopy was done.
