Medicare covers a flexible sigmoidoscopy screening once every 48 months for most people age 45 or older. If you aren’t at high risk, Medicare covers this test 120 months after a previous screening colonoscopy.
Your costs in Original Medicare
You pay nothing if your doctor or other health care provider accepts assignment . If your doctor finds and removes a lesion or growth during your flexible sigmoidoscopy screening, you pay 15% of the Medicare-approved amount for your doctors' services. In a hospital outpatient setting or ambulatory surgical center, you also pay the facility a 15% coinsurance . In these cases, the Part B deductible doesn’t apply.
What it is
Flexible sigmoidoscopy screenings examine the rectum and lower colon.
