Medicare eligible members must submit a copy of their Medicare card to MCHCP and the reason for Medicare coverage.

If Medicare coverage begins before age 65, members will receive a Medicare Disability Questionnaire. MCHCP must receive the completed questionnaire to update the member’s Medicare status.

Active employees and dependents do not need to enroll in Medicare Part B, except if Medicare eligible solely due to End Stage Renal Disease (ESRD). When Medicare-eligible members are no longer actively employed, they should enroll in Medicare Part B and Medicare becomes primary.

Active Employees and Dependents with Medicare
MCHCP is primary and claims are submitted first to the MCHCP medical plan, then to Medicare. The exception is for active employees and dependents with Medicare solely due to End Stage Renal Disease (ESRD). Those in the Health Savings Account (HSA) Plan can no longer contribute to their HSA. However, existing funds can still be used for qualified medical expenses.

Retirees, Survivors, Long-Term Disability and Terminated Vested Subscribers and Dependents with Medicare
Members are automatically enrolled in the United Healthcare (UHC) Group Medicare Advantage Plan for medical coverage and Express Scripts Medicare Prescription Drug Plan (PDP) for prescription drug coverage. MCHCP premium will be adjusted based on Medicare status. Do not enroll in an additional Medicare Advantage, Medigap, Medicare Supplement or another Medicare Part D plan.

Medicare Eligible Due to End Stage Renal Disease (ESRD)

Active Employees and Dependents with Medicare
When eligible for Medicare solely because of ESRD, the MCHCP medical plan will remain the primary plan during the first 30 months of Medicare eligibility. After 30 months, Medicare will become primary and MCHCP secondary.

Retirees, Survivors, Long-Term Disability and Terminated Vested Subscribers and Dependents with Medicare
When eligible for Medicare solely because of ESRD, the MCHCP medical plan will remain the primary plan during the first 30 months of Medicare eligibility. After 30 months, the Medicare eligible member will be automatically enrolled in the United Healthcare (UHC) Group Medicare Advantage Plan for medical coverage and Express Scripts Medicare Prescription Drug Plan (PDP) for prescription drug coverage. The member is responsible for notifying MCHCP of their Medicare status. Do not enroll in an additional Medicare Advantage, Medigap, Medicare Supplement or another Medicare Part D plan.
