Medicare supplement Plan A does offer coverage for some of out-of-pocket expenses that remain after Original Medicare has paid their portion. Of all the Medicare supplement plans, Plan A includes the least amount of benefits. But because of that, it also has the lowest premiums.

Plan A includes the least amount of benefits of all the Medicare supplements. It offers coverage for what are called the core policy benefits. Core policy benefits are included in all Medicare supplements. It is the most basic Medicare Supplement plan.

Medigap Plan A is well-suited for individuals who need a low monthly premium and are not concerned about out-of-pocket hospital costs. It is also only recommended for those who do not travel outside of the United States.


Medicare Supplement Plan A covers only core policy benefits, and they are:

  • Hospitalization – it covers Part A coinsurance and giving coverage for additional 365 days after Medicare benefits end
  • Medical Expenses – covers Part B coinsurance and copayments for outpatient services in hospitals
  • Blood – first 3 pints each year
  • Hospice care – covers Part A coinsurance

Medigap Plan A does not cover the Part A or B deductible, the coinsurance for skilled nursing care, the Part B excess charges, or any coverage for foreign travel emergencies.


Individual premiums for Medigap plans will vary based on which state the individual is seeking coverage in, which carrier they are purchasing from, and also individual factors like gender, age, tobacco use, and a few other details. The average cost for Plan A ranges from $110-$180 per month. In general, Medigap plans premiums are higher in states who have a higher cost of living.


Not all Medicare Supplement plans are available to individuals who are eligible for Medicare but are still under 65 years old. Sometimes, Plan A is the only option and the premium is often double or triple what it is for Medicare beneficiaries who are 65 and older. The reason for the higher premium is that Medicare beneficiaries who have become eligible due to a disability often have higher medical costs.

Individuals who are receiving Social Security disability benefits are the one individuals who are eligible for a second open enrollment period without having to pass medical underwriting. When they turn 65, the second OEP begins and they will have the opportunity to exchange Medigap plan.
