Medical Savings Account (MSA) plans combine a high-deductible health plan with a health savings account.
Medicare deposits money into the account (usually less than the deductible), then you use the money to pay for your health care services during the year. Although you cannot fund your own savings account, MSAs do give you more control over how you use your healthcare dollars (while also protecting you from catastrophic healthcare expenses).
Despite not being able to personally fund your account, MSAs are in many ways the Medicare equivalent of HSA eligible plans in the under-65 market.
TIP: You cannot fund an HSA once you enroll in Medicare, so an MSA is essentially the Medicare alternative to an HSA.
