What is a One Care plan?

A One Care plan, like Tufts Health One Care, is a health plan option that gives you a better, easier way to manage your health. These plans simplify your care by bringing your MassHealth and Medicare benefits together. 

You’ll have one health plan, one insurance card and one person – a care manager – who coordinates your care. Your care team will personalize and simplify your care with all the benefits that you currently receive through MassHealth and Medicare, plus more.
