Medicare covers colonoscopy once every 10 years if the results are normal

Medicare Part B pays for a screening colonoscopy once every 10 years for people age 50 and older with no symptoms and no personal or family history of colorectal cancer. If your last colonoscopy was normal, your next covered screening is 10 years later. If your doctor finds polyps or other abnormalities during the procedure, the frequency may change based on what was found.

You pay nothing for the colonoscopy itself if your doctor performs it as a screening procedure — Medicare covers 100 percent of the cost with no copay or deductible. However, if your doctor removes polyps or takes a biopsy during the procedure, Medicare may reclassify it as a diagnostic procedure rather than screening, which could result in a copay.

Key Takeaways

  • Medicare covers one screening colonoscopy every 10 years for people age 50 and older with normal results and no risk factors.
  • If polyps are removed or a biopsy is taken, the procedure may be classified as diagnostic rather than screening, and you may owe a copay.
  • People with a personal or family history of colorectal cancer may be covered more frequently — ask your doctor what interval applies to you.
  • You should schedule your next colonoscopy about 9 years after a normal result so it is completed before the 10-year window closes.

What happens if polyps are found during screening

If your doctor finds and removes polyps during a screening colonoscopy, Medicare may bill the procedure as diagnostic rather than screening. This reclassification can trigger a copay, typically 20 percent of the cost after your deductible is met. The amount depends on your specific Part B coverage and whether you have supplemental insurance.

The removal of polyps also changes when you need your next colonoscopy. Your doctor will recommend a follow-up interval based on the size, number, and type of polyps removed — this may be 3, 5, or 10 years. Medicare will cover the next procedure at whatever interval your doctor recommends, even if it is sooner than 10 years.

Coverage for people with higher colorectal cancer risk

If you have a personal history of colorectal cancer, a family history of colorectal cancer, or inflammatory bowel disease, Medicare may cover colonoscopy more frequently than every 10 years. Your doctor determines the appropriate screening interval based on your risk factors and medical history.

Bring documentation of your family history or personal medical history to your appointment so your doctor can note it in your records. This documentation helps may support Medicare covers the procedure at the interval your doctor recommends, rather than defaulting to the standard 10-year schedule.

How to track your colonoscopy schedule

Write down the date of your last normal colonoscopy and add 10 years to it — that is when your next screening becomes due. Set a reminder about 9 months before that date to contact your doctor's office and schedule the procedure. Scheduling early helps may support you get an appointment before the 10-year window closes.

Ask your doctor's office for a written summary of your colonoscopy results, including the date and any findings. Keep this document with your medical records. If you change doctors or move, you can show this summary to your new provider so they know when your last screening was and what was found.

What to do if you are unsure when your last colonoscopy was

Contact your previous doctor's office and request your colonoscopy report. The report will show the date of the procedure and the findings. If you cannot locate your previous provider or the records are unavailable, your current doctor can order a new colonoscopy — Medicare will cover it as a screening procedure.

Do not delay seeking care while trying to find old records. If you are over 50 and have never had a colonoscopy, or if you cannot find documentation of a previous one, talk to your doctor about scheduling one now. Medicare covers the procedure regardless of how long it has been since your last screening.

Copays and out-of-pocket costs

For a screening colonoscopy with no polyps removed and no biopsy taken, you pay nothing — Medicare covers the full cost. If polyps are removed or a tissue sample is taken, you typically owe 20 percent of the cost after you have met your Part B deductible for the year. The exact amount depends on the facility where the procedure is performed and your supplemental insurance coverage.

Ask your doctor's office before the procedure whether they expect to bill it as screening or diagnostic. If your doctor anticipates removing polyps, ask what your estimated copay will be. Some offices can give you a cost estimate based on your coverage.

Frequently Asked Questions

What if I had a colonoscopy done at a hospital instead of an outpatient center?

Medicare covers colonoscopy at both hospitals and outpatient centers under the same rules — once every 10 years for screening, with no copay if no polyps are removed. The facility type does not change the coverage frequency or cost to you for a screening procedure.

Does Medicare cover colonoscopy before age 50?

Medicare does not cover screening colonoscopy for people under 50 unless you have symptoms or risk factors that make it medically necessary. If your doctor recommends one before age 50 due to family history or other concerns, talk to your doctor about whether Medicare will cover it as a diagnostic procedure rather than screening.

What if my doctor recommends colonoscopy more often than every 10 years?

If your doctor recommends a shorter interval based on polyp findings, family history, or other medical reasons, Medicare will cover the procedure at that interval. Your doctor's recommendation overrides the standard 10-year schedule. Make sure your doctor documents the medical reason in your chart so Medicare approves the claim.

Can I get a colonoscopy covered if I have symptoms like bleeding or abdominal pain?

Yes. If you have symptoms, your doctor can order a diagnostic colonoscopy, and Medicare will cover it regardless of when your last screening was. Diagnostic colonoscopy for symptoms is covered separately from screening colonoscopy and does not count against your 10-year screening interval.

What happens if I miss my 10-year screening window?

If your 10-year window has passed, you can still get a colonoscopy covered by Medicare. There is no penalty or waiting period. Contact your doctor and schedule the procedure — Medicare will cover it as a screening colonoscopy.
