Routine colonoscopies are essential for early detection and prevention of colorectal cancer, one of the most common cancers in the United States. For individuals relying on Medicare or Medicaid, understanding the scope of coverage for this procedure is essential.

Medicare coverage for colonoscopies
Eligibility and frequency
Medicare provides comprehensive coverage for colonoscopies as a preventive service under Medicare Part B. Eligibility for this coverage begins at age 45, and the frequency of covered screenings depends on your risk factors:
- High risk: Medicare covers a colonoscopy every 24 months if you have a family history of colorectal cancer or conditions like inflammatory bowel disease.
- Average risk: Coverage is provided once every 10 years.
- Follow-up testing: If a flexible sigmoidoscopy was previously performed, Medicare covers a colonoscopy after 48 months.
These screenings are fully covered when performed as preventive care by a provider who accepts Medicare assignment. However, if polyps or tissue are removed during the procedure, it becomes a diagnostic test, requiring you to pay 15% of the Medicare-approved costs for services, though the Part B deductible does not apply.
Anesthesia and prep kits
Medicare Part B also covers anesthesia for the procedure. If a prescription colonoscopy preparation kit is required, it may be covered under Medicare Part D (prescription drug plans). However, out-of-pocket costs can apply based on your specific plan.
Medicaid coverage for colonoscopies
Medicaid also covers colonoscopies but with variations depending on the state. Generally, Medicaid provides coverage for colorectal cancer screening for eligible individuals, often aligning with Medicare’s guidelines. This includes routine screenings for those over 45 and individuals with higher risk factors. In some cases, Medicaid may cover costs associated with diagnostic procedures that Medicare does not fully cover.
Costs and copays
Preventive vs. diagnostic colonoscopies
A colonoscopy initially classified as preventive may incur costs if it transitions to a diagnostic procedure due to the removal of polyps or tissue. In these cases, beneficiaries are responsible for 15% coinsurance for outpatient services, with additional hospital or surgical center charges possible. This coverage gap, often referred to as the Medicare colonoscopy loophole, is set to close entirely by 2030 under recently passed legislation.
Additional coverage options for out-of-pocket costs
- Medigap (Medicare Supplement Insurance): These plans can cover the 15% coinsurance for diagnostic procedures, reducing out-of-pocket expenses.
- Medicare Advantage Plans (Part C): Some plans offer enhanced coverage for prescription drugs and colonoscopy services compared to Original Medicare.
- Extra help for prescription costs: Beneficiaries with limited income may qualify for assistance covering medications, including colonoscopy prep kits.
- State Medicaid assistance programs: Low-income Medicare recipients may qualify for dual eligibility, allowing Medicaid to cover Medicare copays and coinsurance.
What isn’t covered?
Virtual Colonoscopies: Medicare does not cover CT colonography or at-home screening kits as primary diagnostic methods, citing inadequate evidence of their effectiveness in older populations. Similarly, Medicaid coverage for this procedure is rare and state-specific.
Key tips for patients
- Verify costs: Confirm with your provider or insurer whether your colonoscopy will be classified as preventive or diagnostic to avoid unexpected expenses.
- Ask about frequency: Ensure that the recommended screening aligns with the timeline covered by your plan.
- Utilize resources: Programs like Medicaid or Extra Help can alleviate costs for low-income individuals.
