Will Medicare pay an individual to take care of my elderly mom?

Not that I know of. Medicaid might depending on your state's program.

I wonder if you shouldn’t speak with her doctor about this. Medicare won’t pay for anything without a prescription. And even then, they’re pretty stingy with funds. We’ve had many questions on this board about getting paid to be a caregiver and most answers have been “no”. Even if they do pay, I doubt it would be long term. If you want to hire someone, it will probably be self-pay.
