How does one go about obtaining durable medical equipment with Medicare? Do you have to have a Drs. prescription for each item? My Dad needs things like a shower chair, raised rails for the toilet, a bed rail to assist him in getting out of bed, and a wheelchair. If I was to purchase these things on-line and submit the bill to Medicare with a prescription will Medicare reimburse us for the 80%? Thanks in advance...this is all new to me and my research has not really given me the answer.
