I'm an RCA and we now have something like this via United Healthcare. Wife handles all of it.
As I understand its wholly a United thing. They pay you money to get a checkup, blood test, colonoscopy, etc.
Very smart. They'll pay you $50-100 here and there for things that are likely to expose underlying conditions that can be corrected before they turn into major medical events. I think blood, checkups are $50, the colonoscopy was $100.
They send out debit cards you can pay for medical/drugstore things, I think.
