Insurance and Medicare

Several tests can be used to detect polyps or colorectal cancer. Each one can be used alone or in combination with each other. Most insurance plans and Medicare help pay for colorectal cancer screening for people who are aged 50 or older. Colorectal cancer screening tests may be covered by your health insurance policy without a deductible or co-pay.
