Medicaid Cost Sharing for Medicare/Medicaid Dually Eligibles
A. A state is not required to cover any Medicare cost sharing expenses related to payment for
deductibles, coinsurance, or co-payments for dual eligibles which exceed what the state’s
Medicaid program would have paid for such service for a beneficiary who is not a dual
eligible. When a state's payment for Medicare cost-sharing for a dual eligible is reduced or
eliminated the Medicare payment plus the state's Medicaid payment is considered payment in
full. The dually eligible beneficiary cannot be billed the difference between the provider's
charge and the Medicare and Medicaid payment.
B. Medicare Part A crossover nursing facility, hospice and home health agency claims for
dually eligible beneficiaries are reimbursed as listed below:
1. The Medicaid reimbursement combined with the Medicare reimbursement will not
exceed what the Mississippi Medicaid program would have paid for such service for a
beneficiary who is not dually eligible.
2. All service limits will be applied to beneficiaries who are dually eligible when
reimbursement is made toward covered services with service limits. Once the service
limits are reached each state fiscal year, no additional payments will be made for these
services.
3. All providers must accept the Medicare and Medicaid payment as payment in full. The
provider is prohibited from billing the beneficiary the balance between the provider’s
charge and Medicare and Medicaid payments.
C. For Medicare Part A crossover claims from hospitals (inpatient) and all Part B crossover
claims, Medicaid reimburses the full deductible and coinsurance amount for dual eligibles.
