I don't know for sure, but I think Medicare did pay for some equipment, from what families have told me.

Also, I remember a story of some doctors and a seller of those mechanized carts scamming Medicare for millions of dollars.

To be honest, I have no personal dealings with it.
When my friend liquidated estates, the family would tell us Medicare paid for things like potty chairs, lifts, walkers, etc.

Sometimes, the local nursing homes would buy the walkers and potty chairs from the estate, but usually they were sold for maybe $5.

A lady did tell me not long ago that Medicare would pay for one device in a time period - maybe a year.
