As
@katlupe said, when you have a chronic health condition and are low income, Medicare will put you on a SNP(special needs plan) advantage plan that goes along with Medicaid.
I have Devoted Health and have basically the same type of plan as Katlupe has, and I get an OTC allowance and a food card. The rewards she is talking about are for having medical tests done, like bone density, and things similar to that. Some companies send you a debit card with money for that and other companies offer several kinds of gift cards to choose from.
The ad that offers the $1200 food card benefit is probably legitimate, but it would depend on the size of family, and your income, as to how much food benefit you get, and the $1200 might be an annual benefit of $100 per month.
If you find a Medicare insurance broker, they can compare plans that you are eligible for, for ALL companies that serve your area, and then they will help you choose the plant that best meets your needs. We have had the same agent for the last 10 years and see him once each fall to go over the new plans and changes to the plan we have now.
Also, you can go online, choose a company and see what plans they offer. You do not need to talk with someone on one of those TV ads, you can just go and read it on the company website.
Last year, when we received the Notice of Change (which you get each year from your company), it said that our vision benefit was going to be less in 2026, so I went online and checked plans for other companies, that way when we met with our agent (actually it was just a phone conversation ) I already had an idea what other companies were offering, and what questions I needed to ask our agent.
