Regular dialysis transportation to and from your dialysis treatment appointments are not usually covered by Medicare.
However Medicare does cover the cost of an ambulance in an emergency to get you to the hospital in a life and death situation when you're on dialysis.
If you need transportation to and from your dialysis treatment appointments and can't afford the transportation you can speak with the dialysis treatment staff and they can get you signed up for free transportation to and from your dialysis treatment appointments.
Your health insurance or other medical insurance usually covers the cost of dialysis transportation.
The dialysis treatment center staff will let you know how the dialysis transportation is covered.
