Medicare is usually the leader on what sort of medications are approved for payment, with private insurance companies typically following suit. Not this time. It was weeks after President Joe Biden said private insurance companies had to cover the cost of at-home COVID test that finally Medicare announced it would cover up to 8 tests per home per month. Medicare will pay pharmacies and other entities directly to allow enrollees to pick up the free tests. Until the tests become available in drug stores, you can order them at wwww.CovidTests.gov.
