HAP Medicare Supplement (Medigap) Plans in Michigan

Medicare Supplement plans, also known as Medigap plans, are offered by private companies such as Alliance Health and Life Insurance Company® to help pay some of the health care costs Original Medicare doesn’t cover like copays, coinsurance and deductibles. It only supplements your Original Medicare benefits and there are no prescription drug benefits included in these plans. You’ll still need to have Medicare Parts A and B.

HAP fills the gaps in Original Medicare 

With Original Medicare, you’re covered for many hospital and medical expenses, but there are some gaps in that coverage you may have to pay; such as deductibles, coinsurance and copays; and those costs can add up quickly:

  • Medicare Part A has an upfront deductible for hospitalization – a deductible you pay each benefit period before your Medicare coverage begins.
  • If you stay in the hospital more than 60 days, you begin paying a copay per day.
  • After 90 days in the hospital, your copay increases.
  • You pay 20% coinsurance for most doctors’ services after you pay your Part B deductible each year.
  • You pay 100% for emergency care received outside the U.S., except under limited circumstances.

With HAP Alliance Medicare Supplement (Medigap) plans, you can fill the coverage gaps listed above and know that you're protected with a plan from Alliance Health and Life Insurance Company (Alliance). With HAP Alliance Medicare Supplement, you have emergency care anywhere in the world.
