How to compare Medicare Supplement insurance plans

Comparing Medicare Supplement Insurance plans side-by-side allows you to see which policies cover the health care services you need. There are three steps involved in comparing Medicare Supplement Insurance plans:

  • Find available plans in your area
  • Compare plan benefits and coverage
  • Compare plan costs

1. Find available plans in your area

Medicare Supplement Insurance plans are sold by private insurance companies, and not every company sells every plan. As a result, not every plan is made available in each area.

2. Compare coverage

Once you find out which plans are available where you live, it’s time to compare coverage.

There are nine benefit areas that Medicare Supplement Insurance plans can potentially cover, and each benefit addresses some of Original Medicare’s out-of-pocket expenses.

  • Part A deductible
    Before Medicare Part A coverage kicks in, beneficiaries must meet a $1,408 deductible for each benefit period in 2020.

    A benefit period begins the day you’re admitted to a hospital for inpatient care, and the period ends when you’re released and haven’t received inpatient hospital care for 60 days in a row. You could potentially face more than one benefit period in a year, and you must meet your Part A deductible each time before your Part A benefits kick in.

  • Part A coinsurance and hospital costs
    In 2020, Medicare Part A requires beneficiaries to pay coinsurance of $352 per day for days 61-90 of an inpatient hospital stay, and $704 per day thereafter.

  • Part B deductible
    Medicare Part B beneficiaries must satisfy a $198 annual deductible in 2020 before any Part B coverage takes effect.

  • Part B coinsurance and copayments
    Medicare Part B requires a 20 percent coinsurance payment for all covered services and medical equipment once the annual deductible is met.

  • Part A hospice care coinsurance
    During hospice care, Part A may mandate minor copayments for prescription drugs related to hospice service, along with a 5 percent coinsurance payment for inpatient respite care.

  • Skilled nursing facility coinsurance
    Longer stays in a skilled nursing facility require Part A copayments of $176 per day in 2020 for days 21-100 of an inpatient stay.

  • Part B excess charges
    If you receive Part B services from a health care provider that does not accept Medicare assignment, you may be subject to excess charges of up to 15 percent of the Medicare-approved amount for the service.

  • First three pints of blood
    The first three pints of blood that are needed for a blood transfusion are not covered by Original Medicare.

  • Foreign travel emergency care
    Emergency medical care that is received outside of the U.S. is not typically covered by Original Medicare, except under special circumstances.

Once you’re familiar with the expenses that can covered by some Medicare Supplement Insurance plans, you can consult the chart above to see which plans provide which benefits.

This comparison chart can help you decide which Medicare Supplement Insurance plan may be the best fit for your needs.

If you're a new Medicare beneficiary starting on or after January 1, 2020, you will not be able to enroll in Plan F or Plan C. If you were enrolled in Medicare before that date, you may be able to enroll in either plan if one is available in your area.

3. Compare Medicare Supplement Insurance plan costs

Although the coverage offered by each type of Medicare Supplement Insurance plan is standardized and remains consistent no matter where a plan is sold, the cost can vary from one location or company to another.

When you visit, you’ll be able to compare prices from insurance companies in your area to find the best Medicare Supplement Insurance plan for your needs.
