The plan provides coverage for medical supplies and durable medical equipment (DME) that are necessary for the treatment of a medical condition, such as wheelchairs, walkers, and oxygen equipment.

Historical Context

Medicare Part B was created as part of the Social Security Amendments of 1965, spearheaded by President Lyndon B. Johnson, with the aim of providing comprehensive healthcare coverage to America’s elderly and disabled populations. The program has evolved over the decades to encompass a wider range of services and adapt to modern healthcare needs.
