What is Medicare?

Medicare is a federal health insurance program through the Centers for Medicare & Medicaid Services (CMS). The Social Security Administration started Medicare to help people pay for their health costs if they’re 65 or older or have certain disabilities. Payroll taxes and Medicare beneficiaries mostly pay for it.

Medicare has four parts.

  • Part A – Hospital Coverage (inpatient hospital stays, skilled nursing facilities, hospice, and some home health care)
  • Part B – Medical Coverage (doctor visits, outpatient care, and some home health care)
  • Part C – Medicare Advantage (from a private company and pays in place of Original Medicare)
  • Part D – Prescription Drug Coverage

Original Medicare (Parts A and B)

Original Medicare is the traditional Medicare program managed by the federal government. It includes Part A and Part B coverage but only covers about 80% of your healthcare costs. Original Medicare does not include coverage for prescription drugs (Part D plan). You should consider signing up for a separate Part D plan to ensure that you have coverage for your prescription drug needs.

Medicare Advantage (Part C)

Medicare Advantage combines all your coverage (doctor’s visits, hospital, and pharmacy) into one plan, like the health plan you might have used while working. In addition, Medicare Advantage plans often cover services that Medicare doesn’t, like care coordination, health coaching, dental, vision, and hearing. Medicare Advantage plans have yearly limits to keep your out-of-pocket costs lower. Original Medicare does not. Medicare Advantage $0 premium plans have become popular recently, where you do not have to pay a monthly premium for the plan; you must still pay your Part B premium.

Medicare Supplement (Medigap)

Medicare Supplement plans help pay for the costs that Original Medicare doesn’t pay for, like coinsurance, copayments, and deductibles. With these plans, the government sets the rules, and the plans only cover services that Original Medicare covers. Medicare Supplement plan premiums often increase with age. They also do not include coverage for prescription drugs (Part D plan). You should consider signing up for a separate Part D plan to ensure that you have coverage for your prescription drug needs.

Things to Consider When Choosing a Medicare Plan:

  • Ensure you can continue to see your doctor
  • Review the formulary (drug list) to make sure your drugs are covered
  • Look at how your past healthcare costs line up with a plan. Consider if there is an opportunity to change plans to save money.
  • Look for additional plan perks, like health coaching and care coordination, fitness benefits, and more.
  • Check to see if you’re eligible for Extra Help through Medicare.

Enrolling in Medicare

Initial Enrollment Period

You have the three months before the month you turn 65, the month of your birthday and the three months after the month you turn 65 to enroll in a Medicare plan for the first time. So if your birthday is in April, you have seven months from January through July to sign up.

Annual Enrollment Period (October 15-December 7)

The Annual Enrollment Period, or AEP, lasts from October 15 to December 7. During that time, you can enroll in a new plan or make changes to your plan, like switching to a different Medicare Advantage plan.

Special Enrollment Period

Outside AEP, you can only change plans in special situations, like if you move out of the service area or if your plan ends its contract.

Open Enrollment Period (January 1-March 31)

From January 1 to March 31, you can switch to Original Medicare and join a Medicare prescription drug plan, or you can switch to another Medicare Advantage plan.
