Medigap in Massachusetts

You have guaranteed issue rights to buy Medicare supplemental coverage in Massachusetts, but the policies available there are different from the standardized Medigap plans available in most states. There are three different Medicare Supplement plans in Massachusetts, and they all offer the same basic benefits.

Medigap Plans Available in Massachusetts

Massachusetts is one of three states that do not offer the same standardized Medigap plans common across the rest of the United States. The other two states are Minnesota and Wisconsin.

There are three types of Medigap plans standardized throughout Massachusetts.

Massachusetts Medigap Plans
  • Core Plan
  • Supplement 1 Plan
  • Supplement 1A Plan

The plans provide certain basic benefits that are common across all three types of Medigap plans.

Basic Benefits in All Massachusetts Medigap Plans
  • Inpatient hospital care covering Medicare Part A coinsurance and coverage for 365 additional hospital days after Medicare coverage ends.
  • Medicare Part B coinsurance (usually 20 percent of the bill) for medical costs such as doctor visits.
  • Medicare Part A hospice copay or coinsurance.
  • Costs of first three pints of blood each year.

Medigap — sometimes called Medicare Supplement — helps you pay out-of-pocket expenses that Medicare Part A and Part B do not cover. These include copayments, deductibles and coinsurance.

You cannot use Medigap to cover your Original Medicare premiums.

Massachusetts Medigap Core Plan

The Massachusetts Medigap Core Plan provides the least amount of benefits.

In addition to the basic benefits offered by all three plans, it covers 60 days every calendar year in mental health hospitals.

The Core Plan also covers health benefits that the state requires insurers to cover. These include such things as annual mammograms and pap smears.

Benefits Not Covered by the Massachusetts Medigap Core Plan
  • Medicare Part A inpatient hospital deductible
  • Medicare Part A skilled nursing facility coinsurance
  • Medicare Part B deductible
  • Foreign travel emergency medical and hospital costs

Massachusetts Supplement 1 and 1A Plans

The biggest difference between the Massachusetts Supplement 1 and 1A Plans is that the Supplement 1 Plan covers the Medicare Part B medical insurance deductible. The Supplement 1A does not cover it.

Massachusetts is phasing out the Supplement 1 plan. If you became eligible for Medicare on or after Jan. 1, 2020, you can no longer buy the Supplement 1 Plan. But you are still eligible for the Supplement 1A plan.

If you were eligible for Medicare before the shutoff date, but have not enrolled in Medicare, you may still be able to purchase the Supplement 1 plan.
