There is a mistake above. It's not called "Care One." The correct name of that program to blend Medicare and MassHealth is "One Care." Here's a link:

One Care: MassHealth plus Medicare

Excerpt:

One Care is a new and easier option for people with disabilities to get the full set of services provided by both MassHealth and Medicare. With One Care, you have one plan, one card, and one person to coordinate your care.

This program, which you would have to apply for, after getting enrolled in Part B, would pretty much eliminate copayments for seeing a doctor. Then you could afford to get the care you are wanting and, I'm sure, needing.
