Final answer:
In the context of Medicare, crossover refers to the coordination of benefits between different health insurance plans.
Step-by-step explanation:
In the context of Medicare, crossover refers to the coordination of benefits between different health insurance plans. When a Medicare beneficiary has additional coverage from another health insurance provider, such as an employer-sponsored plan or Medicaid, the two plans work together to pay for the beneficiary's healthcare expenses.
For example, if a Medicare beneficiary also has Medicaid, Medicaid may cover certain healthcare services that are not covered by Medicare. This coordination of benefits helps ensure that the beneficiary receives comprehensive coverage and minimizes their out-of-pocket expenses.
Additionally, crossover arrangements can happen between Medicare and other types of insurance, such as Medicare Advantage plans or Medigap policies, which provide supplemental coverage to fill the gaps in traditional Medicare.
