If you opt out of Medicare Part A, you will also lose your Social Security benefits, per the decision brought down in Hall vs. Sebelius and upheld in a court of appeals in Feb, 2012. These retirees sought to drop Medicare Part A because it interfered with a superior health insurance plan they received. The court ruled that they would have to pay back their Social Security earnings if they were to opt out of Medicare Part A. However, they could stay in Medicare Part A and not use the benefits.
