Medicaid can help pay for an electric wheelchair. Medicare can also be used to subsidize the costs, if Medicaid doesn'tt approve a 100% coverage. Medicare Plan B, for example, can pay to rent or purchase an electric wheelchair if your mom'ss doctor writes her a prescription. It will have to be proven that you Mom will need to wheelchair to get around, both indoors and outdoors, for an honest medical practitioner to write such a prescription.
