Understanding the Benefits of Medicare Supplement Plans

Home » Resources » Understanding the Benefits of Medicare Supplement Plans

Medicare Supplement plans are private insurance policies designed to work alongside Original Medicare (Part A and Part B) and fill in the coverage gaps. These plans are sold by private insurance companies and are regulated by both federal and state laws. It’s important to note that Medicare Supplement plans are standardized and labeled with letters, such as Plan A, Plan B, Plan C, and so on. Each standardized plan must offer the same basic benefits, regardless of the insurance company offering it. However, the costs and additional benefits can vary from one insurer to another.

Coverage Provided by Medicare Supplement Plans

Medicare Supplement plans provide coverage for various healthcare services, including hospital stays, medical procedures, and outpatient care. Here’s an overview of the benefits typically offered by these plans:

  1. Medicare Part A Coinsurance and Hospital Costs: This coverage includes the cost of hospital stays beyond the coverage provided by Original Medicare.
  2. Medicare Part B Coinsurance and Copayment: This coverage helps pay for the coinsurance and copayments required for medical services covered under Medicare Part B.
  3. Blood: Medicare Supplement plans typically cover the cost of the first three pints of blood needed for a medical procedure.
  4. Part A Hospice Care Coinsurance or Copayment: This coverage helps cover the coinsurance or copayment required for hospice care received under Medicare Part A.
  5. Skilled Nursing Facility Care Coinsurance: Some Medicare Supplement plans cover the coinsurance required for skilled nursing facility care.
  6. Part A Deductible: Certain plans provide coverage for the deductible associated with Medicare Part A.
  7. Part B Deductible: Some plans cover the deductible for Medicare Part B, which is the amount beneficiaries must pay out of pocket before their coverage begins.
  8. Part B Excess Charges: Medicare Supplement plans can help cover the excess charges that healthcare providers may charge above the Medicare-approved amount.

Is There an Annual Out-of-Pocket Maximum Limit?

One important aspect to consider when evaluating Medicare Supplement plans is the presence of an annual out-of-pocket maximum limit. An out-of-pocket maximum is the total amount that a beneficiary must pay in a calendar year before their plan starts covering 100% of the costs. While Medicare Supplement plans offer comprehensive coverage for various healthcare services, they do not have a standard out-of-pocket maximum limit like Medicare Advantage plans do.

Comparison with Medicare Advantage Plans

Medicare Advantage (Part C) plans are an alternative to Original Medicare and Medicare Supplement plans. These plans are offered by private insurance companies and combine the benefits of Medicare Parts A and B into a single plan. Medicare Advantage plans often include additional benefits, such as prescription drug coverage (Part D), dental, vision, and hearing services. Unlike Medicare Supplement plans, Medicare Advantage plans typically have an annual out-of-pocket maximum limit, which can provide beneficiaries with financial protection in case of significant medical expenses.


Medicare Supplement plans offer valuable coverage that can help fill the gaps in Original Medicare. While they do not have an annual out-of-pocket maximum limit, these plans provide beneficiaries with peace of mind by covering a significant portion of their healthcare costs. It’s important for individuals to carefully evaluate their healthcare needs and budgetary considerations when choosing between Medicare Supplement plans and Medicare Advantage plans. By understanding the coverage provided by each option, beneficiaries can make an informed decision that best suits their unique circumstances.


  • Medicare Supplement plans, also known as Medigap policies, work alongside Original Medicare to provide additional coverage.
  • These plans fill the gaps in Medicare Part A and Part B, helping beneficiaries with various healthcare costs.
  • Medicare Supplement plans do not have an annual out-of-pocket maximum limit, unlike Medicare Advantage plans.
