Some people are what’s known as dually eligible: eligible for both Medicare and Medicaid. If you’re dually eligible, you can have both Medicare and Medicaid. They work together to provide your health coverage and lower your medical costs.
If you’re dually eligible, Medicare is always the first (primary) payer. After Medicare pays its share, Medicaid (the secondary payer) covers the remaining cost for Medicaid covered expenses. Medicaid can help cover the costs of Medicare premiums, copayments, and deductibles as well.
Medicaid covers some expenses Original Medicare doesn’t cover, such as personal care assistance in your home, so getting both Medicare and Medicaid if you qualify is usually a great idea.
