Medicare Medical Savings Account (MSA) plans are private companies that the federal government pays to administer Medicare benefits. Like all Medicare Advantage Plans, MSA plans must provide you with the same benefits, rights, and protections as Original Medicare, but they may do so with different rules, restrictions, and costs. Some MSAs offer additional benefits, such as vision and hearing care. Unlike other Medicare Advantage Plans, MSA plans include both a high deductible health plan (HDHP) and a bank account to help pay your medical costs.
You must have both Parts A and B to join an HDHP and an MSA, and generally you will continue paying your Medicare Part B premium. Some MSA plans charge an additional premium, on top of your Part B premium. MSA plans cannot offer Part D coverage. To receive coverage for your prescription drugs, you must join a stand-alone Part D plan.
