Medicare Overview
Get to know the ABCDs of Medicare
Medicare was established in 1965 to help people who are 65 and over or have disabilities pay for the rising costs of medical care. Over the years, it has changed. Whether you are new to Medicare or want a refresher, here are a few resources to help you understand the costs, benefits, and choices offered by Blue.
Eligibility for Medicare
You are generally entitled to Medicare if you meet any of the following criteria:
- You are age 65 or above
- You already receive Social Security or Railroad Retirement Board (RRB) benefits
- You have been diagnosed with end-stage renal disease (ESRD) or amyotrophic lateral sclerosis (ALS, “Lou Gehrig’s disease”)
Your Initial Enrollment Period is based on the month in which you turn 65. It begins three months before your birth month and extends until three months after your birth month.
Medicare (Part A and Part B)
Medicare Part A is offered at no cost to most people eligible for Medicare. Medicare Part B is available for a monthly premium to most people eligible for Medicare. Medicare premiums, deductibles, and cost-sharing amounts are set by the federal government each fall for the next year.
Part A: Hospital Coverage
What's Covered
- Inpatient hospital stays
- Care in a skilled nursing facility
- Home health care and hospice care
What's not Covered
You pay a share of the costs because of things like day limits, deductibles, and coinsurance.
What's Covered
- Doctor's services and tests
- Outpatient care
- Durable medical equipment and some medical services
- Supplies not covered by Medicare Part A.
Part B also covers some preventive services
What's not Covered
Doesn't cover deductibles, copays, and coinsurance
Medicare Advantage (Part C)
With a Medicare Advantage plan, you get Medicare Part A and Part B benefits and some plans may offer extra benefits. Some Medicare Advantage plans also include prescription drug coverage in one plan. Like all Medicare plans, benefits, premiums, and copayments may change from year to year.
Part C: Medicare Advantage
What's Covered
- Medicare Part A and Part B benefits
- Some plans may offer extra benefits
What's not Covered
If you go to a doctor or other healthcare provider that does not belong to your plan's network, your services may not be covered or your costs could be higher. Medicare Advantage plans also require cost sharing such as coinsurance, copays, and deductibles.
Prescription Drug Plans (Part D)
Medicare works with health plans and other private companies to offer prescription drug coverage. These Medicare-approved plans are called standalone Part D plans.
Part D: Prescription Drug Plans
What's Covered
- Generic drugs
- Brand-name drugs
What's not Covered
Not all Plans have the same formulary (the list of covered drugs) and you will need to use a network pharmacy to ensure your drugs are covered.
Medicare Supplement Plans (Medigap)
Medigap plans are sold by private health coverage companies. They help pay for some of the healthcare costs or “gaps” that Medicare Part A and Part B don't cover. In most cases, you must have both Medicare Part A and Part B to purchase a Medigap policy.
Medicare Supplement Plans (Medigap)
What's Covered
- Your share of costs for services partially covered by Part A and Part B
- Things that require out-of-pocket expenses like coinsurance, deductibles, etc.
What's not Covered
Most other costs not covered by Medicare
