Claim process

Medicare claim process

Medicare and insurers work together to pay claims. But how it works depends on the type of plan you have.

Remember that if you use a provider in your plan network, the provider will submit claims for you. If you use an out-of-network provider, you will need to submit your own claim.

  • You present your Medicare ID card to your health care provider
  • Your provider sends your claim to Medicare
  • Medicare pays first and sends payment directly to the provider
  • Medicare sends you a statement saying what you owe
  • You pay the balance to the provider directly

  • You present your Medicare ID card and insurance ID card to your health care provider
  • Your provider sends your claim to Medicare and your insurer
  • Medicare is primary payer and sends payment directly to the provider
  • The insurer is secondary payer and pays what they owe directly to the provider
  • Then the insurer sends you an Explanation of Benefits (EOB) saying what you owe, if anything
  • You pay the balance to the provider directly

  • You present only your insurance ID card to your health care provider (store your Medicare ID card someplace safe)
  • Your provider sends the claim to your insurer only
  • The insurer is primary payer and pays what they owe directly to the provider
  • Then the insurer sends you an Explanation of Benefits saying what you owe, if anything
  • You pay the balance to the provider directly
