Colorectal Cancer Screening

Preventive Care

Colon cancer is often preventable because polyps can be found and removed before they turn into cancer.

Choose the screening option you’ll actually complete.
Ask if family history changes timing/frequency.
Report symptoms quickly (blood in stool, persistent changes).

Medicare Coverage

Medicare covers several colorectal cancer screening options under Part B, each with its own frequency rules.

Screening vs diagnostic matters: symptoms can change billing and cost-sharing.
Many preventive screenings are $0 if rules are met and the provider accepts assignment.

Key takeaways

Pick a screening path you’ll follow through on.
Know your family history.
Screening vs diagnostic is a common cost surprise.

Good to Know

Provider Accepts Assignment

In Original Medicare, “accepts assignment” means a provider agrees to Medicare’s approved amount as full payment (with you paying any required deductible/coinsurance). For many preventive services, using a provider who accepts assignment can help keep your costs lower and more predictable.

Frequency Limits

Many Medicare preventive services have frequency limits, meaning Medicare covers them only as often as allowed (for example, once every 12 months, once every five years, or once in your lifetime). The schedule varies by service.

Eligibility Rules

Many preventive services are covered only if you meet Medicare’s eligibility rules. These rules can include your age, risk factors, medical history, lab results, diagnoses, or timing (for example, being “at risk” for a screening).
