Medicare is federal health insurance for people who are:
65 years old or older
younger than 65 years old with certain disabilities
any age with End-Stage Renal Disease (permanent kidney failure that requires dialysis or a kidney transplant)
Most people get their Medicare health care coverage in one of two ways. Your costs may change, depending on your plan, coverage, and the services you use.
Part A: Medical Insurance
Helps cover in-patient care in hospitals
Helps cover skilled nursing facility, hospice, and home health care
Part B: Medical Insurance
Part C: Medicare Advantage
A Medicare Advantage Plan is a type of Medicare health plan offered by a private company that contracts with Medicare to provide you with all your Part A and Part B benefits.
Medicare Advantage Plans include:
Health Maintenance Organizations (HMO)
Preferred Provider Organizations (PPO)
Private Fee-for-Service Plans (PFFS)
Special Needs Plans (SNPs)
Medicare Medical Savings Account Plans
If you are enrolled in a Medicare Advantage Plan, Medicare services are covered through the plan and are not paid for under Original Medicare.
Most Medicare Advantage Plans offer prescription drug coverage. In some types of plans that do not offer drug coverage, you can join a Medicare Prescription Drug Plan (Part D).
Medigap policies cannot work with Medicare Advantage Plans.
Part D: Prescription Drug Coverage
Part D helps cover the cost of prescription drugs and may help lower prescription drug costs. You can choose this coverage. Private companies approved by Medicare run these plans. Plans cover different drugs. Medically- necessary drugs must be covered.
Medigap: Medicare Supplement Insurance
You can choose to buy this private insurance sold by private companies. An employer or union may offer similar coverage. This insurance can help pay some of the health care costs that Original Medicare does not cover. For examples, copayments, coinsurance, and deductibles. You must have Medicare Part A and Part B.
You should sign up for Medicare three months before you turn 65. You should apply even if you do not plan to receive retirement benefits because you are working. Apply online at ssa.gov/medicare. You can also call 1-800-772-1213 (TTY: 1- 800-325-0778) Monday through Friday from 7 a.m. to 7 p.m.
