Medicare is a federal health insurance program for individuals 65 or over. It may also be available to individuals who have been deemed “disabled” by the Social Security Administration for two years.

Medicare: What You Need to Know

There are four components to Medicare. It’s important to know what coverage is provided in each component to receive the best care.

Part A covers certain inpatient hospitalization, hospice care and limited home care services. When an individual becomes eligible for Medicare, Part A is typically available with no monthly cost. If you have paid Medicare taxes while working, Part A doesn’t require any premium.

Part B covers outpatient services like doctor’s visits and preventive services. Part B includes a deductible (this is the amount of money you are expected to pay out-of-pocket towards your health care before your health care insurer pays) that may change year to year.

Part C (also known as Medicare Advantage) offers private health plans and can be useful for those looking for all-in-one medical and drug coverage. However, some Medicare Advantage HMOs restrict which doctors and hospitals you can use. These plans must offer at least the same benefits as other parts of Medicare that are available but have different rules, costs and coverage restrictions.

Part D (also known as Medicare Prescription Drug Plan) covers outpatient prescription drugs.

Be aware of Medicare “gaps.” Even with Medicare A and B there are still “gaps” in coverage. For example, there is a 20% co-insurance fee for Part B services, and neither A nor B offers drug coverage. Some individuals choose to supplement their coverage with a retiree plan if their former employer offers one.

According to the Kaiser Family Foundation, medigap enrollment and consumer protections vary across states. In all but four states, insurance companies can deny private Medigap insurance policies to seniors after their initial enrollment in Medicare because of a pre-existing medical condition, such as a cancer diagnosis, except under limited, qualifying circumstances.

Understanding Your Insurance and Cancer

When deciding on a Medicare plan, know what part(s) can work best for you. Part A and Part B can cover chemotherapy but there may be out-of-pocket costs, like a co-payment. Cancer screenings, such as colonoscopies, are also covered by Part B.

Clinical trials are research studies that evaluate new cancer treatments. Clinical trials may provide an opportunity for patients to access the latest in cancer care and help identify new therapies for people with cancer. If you are interested in participating in a clinical trial, Part A and/or Part B may cover some of the costs. It may be helpful to ask before enrolling in a clinical trial what your Medicare plan will cover. Read CancerCare’s ‘Understanding Your Insurance Coverage’ fact sheet for other questions you may want to consider in order to fully understand your health care coverage.
