Hi @rick. Being Canadian, I wouldn't know first hand how Medicare works, however, ostomy supplies seem to be covered in this FAQ:

"Medicare Part B pays for 80% of allowable charges for ostomy supplies after you meet the Medicare Part B deductible."

A lot of other questions are also answered in that page. I hope that helps!

Get a Medicare advantage plan if you can. A PPO if at all possible. My monthly ostomy supplies only have a $40 co pay with my Humana PPO Medicare advantage plan.
