How can we help you? Do I have to pay the 20% co-payment? 2 out of 3 found this helpful If you qualify and have met your deductible, Medicare will pay up to 80 percent of the cost of your power wheelchair. You’re responsible for paying the remaining 20 percent of the cost of your power wheelchair either directly or through supplemental insurance. Please note that as of January 2011, the Medicare benefit has changed to a 13-month rental, so you will be billed monthly over the 13-month period. Was this helpful?
