Medicaid is by law intended to be the payer of last resort. As such, all other third-party resources, including Medicare, must first meet their legal obligation to pay claims before Medicaid pays. Therefore, Medicare will still remain the primary coverage, and Medicaid will cover things within its benefits package that Medicare will not cover. There is a notable situation where getting Medicaid can adversely affect a retiree’s coverage. Another thing to bear in mind is that two of the three Managed Long-Term Care (MLTC) plan types manage their members Medicare benefits as well. If someone enrolls in one of those plan types, it may have a very large impact on his Medicare.
