Is Medicare Cover Extended to Colonoscopies?

Updated: Oct 28, 2023

Colonoscopies allow doctors to check for colorectal polyps or cancer. They are an essential screening tool to detect colon cancer early, when it is most treatable. Medicare provides coverage for colonoscopy procedures under certain circumstances.

Below we’ll look at Medicare’s coverage specifics for screening and diagnostic colonoscopies. Understanding the rules can help you get the testing you need while minimizing out-of-pocket costs.

Medicare Coverage for Colorectal Cancer Screenings

Original Medicare Part B covers a variety of colorectal cancer screening tests including:

  • Colonoscopy - every 24 months for high-risk individuals; every 10 years otherwise

  • Fecal occult blood test - every 12 months

  • Flexible sigmoidoscopy - every 48 months

  • Cologuard DNA testing - every 3 years

For screening colonoscopies, Medicare Part B covers the full cost as long as you see a provider who accepts Medicare assignment. You pay nothing as long as your doctor codes it properly as a preventive screening colonoscopy.

When Diagnostic Colonoscopies Are Covered

In some cases a screening colonoscopy may transition into a diagnostic procedure during the procedure itself, like if a doctor finds and removes a polyp for biopsy.

Medicare still covers diagnostic colonoscopies but you may have to pay the Part B deductible and coinsurance. Coverage levels depend on your symptoms and medical history. Talk to your doctor to understand the coding being used to avoid surprise bills.

Medicare Advantage Coverage for Colonoscopies

Medicare Advantage Plans must cover colonoscopies without cost sharing when used as a preventive screening test same as Original Medicare.

For diagnostic colonoscopies, your out-of-pocket costs may be lower with Medicare Advantage since many plans have annual caps that limit your spending. Costs will vary by plan.

When Medicare May Not Cover Colonoscopy Costs

There are certain situations where Medicare will not cover the full cost of a colonoscopy:

  • If your doctor bills a screening procedure as diagnostic without proper cause

  • Colonoscopies done more frequently than the coverage timeframes allow

  • When performed by an opt-out or non-participating Medicare provider

  • If coded improperly by your provider

Make sure your provider follows Medicare guidelines to avoid unexpected bills. Getting an Estimate of Costs form ahead of time can protect against surprise charges.

Should You Get Screened for Colorectal Cancer?

Talk to your doctor about the right colorectal cancer screening schedule for you based on your personal risk factors and family history.

When used as recommended, Medicare provides vital coverage to help beneficiaries get potentially life-saving colon cancer screening without financial barriers. Take advantage of these benefits to stay healthy.
