Colorectal cancer is a cancer that starts in the colon or rectum. Colorectal cancer screenings can detect conditions that may lead to colorectal cancer.
Medicare Part B covers different colorectal cancer screenings, each with separate eligibility requirements:
- Fecal occult blood test – once a year (every 12 months) if you are age 50+
- Flexible sigmoidoscopy – once every four years (48 months) if you are age 50+ and at high risk, or once every 10 years after a colonoscopy if you are age 50+ and not at high risk
- Colonoscopy – once every two years (24 months) if you are at high risk, or once every 10 years if you are not at high risk (but not within 48 months of a flexible sigmoidoscopy)
- Barium enema – once every two years (24 months) if you are age 50+ and at high risk, or once every four years (48 months) if you are age 50+ and not at high risk (but not within 48 months of a flexible sigmoidoscopy)
Note: You do not have to be age 50+ to be eligible for a colonoscopy.
You may be at high risk for colorectal cancer if you:
- Have a family history of the disease
- Have had colorectal cancer or colorectal polyps
- Or, have a had inflammatory bowel disease
If you qualify, Original Medicare covers fecal occult blood tests, flexible sigmoidoscopies, and colonoscopies at 100% of the Medicare-approved amount when you receive the service from a participating provider. This means you pay nothing (no deductible or coinsurance). Medicare Advantage Plans are required to cover these tests without applying deductibles, copayments, or coinsurance when you see an in-network provider and meet Medicare’s eligibility requirements for the service.
Barium enemas are covered at 80% of the Medicare-approved amount. When you receive the service from a participating provider, you pay a 20% coinsurance after you meet your Part B deductible. If you are enrolled in a Medicare Advantage Plan, contact your plan for cost and coverage information for barium enemas. Your plan’s cost-sharing may apply when seeing in-network providers.
During the course of your colorectal cancer screening, your provider may discover and need to investigate or treat a new or existing problem. This additional care is considered diagnostic, meaning your provider is treating you because of certain symptoms or risk factors. Medicare may bill you for any diagnostic care you receive during a preventive visit.
