The benefits of Part A of Medicare

Even a person with employer health insurance can benefit from enrolling in Part A, which can provide secondary coverage of hospital and nursing home expenses.

Part A charges no premiums to anyone who’s worked enough to qualify for Social Security benefits — at least 40 quarters in jobs that deducted Social Security payroll taxes from their pay.

Enrolling in Part A invalidates a person’s entitlement to have pre-tax contributions made to a health savings account.
