Colon Cancer Screenings (Colorectal)

How often is it covered?

  • Fecal Occult Blood Test: Once every 12 months.
  • Flexible Sigmoidoscopy: Generally, once every 48 months, or 120 months after a previous screening colonoscopy for people not at high risk.
  • Screening Colonoscopy: Generally once every 120 months (once every 24 months if you're at high risk), or 48 months after a previous flexible sigmoidoscopy.
  • Barium Enema: Your doctor can decide to use this test instead of a flexible sigmoidoscopy or colonoscopy. This test is covered every 24 months if you are at high risk for colorectal cancer and every 48 months if you aren't at high risk.

You're at high risk if you have any of the following risk factors:

  • A close relative (sibling, parent, or child) who has had colorectal cancer or an adenomatous polyp (a type of polyp that could become cancerous)
  • A family history of familial adenomatous polyposis (this involves multiple adenomatous polyps, often in the hundreds, and carries a very high risk of colon cancer)
  • A family history of hereditary nonpolyposis colorectal cancer (a type of colorectal cancer that runs in families and tends to cause cancer at a relatively young age - under 45 years)
  • A personal history of adenomatous polyps
  • A personal history of colorectal cancer
  • A personal history of inflammatory bowel disease, including Crohn's Disease and ulcerative colitis

Who’s eligible?

All people with Medicare are eligible for a screening colonoscopy. All other colorectal screenings are available to people with Medicare age 50 and older.
