I am 63, 5 ft. 1 1/2 in. with multiple chronic medical conditions. I am on disability. My husband is also disabled. Our income is Social Security and a very small VA disability benefit for my husband. I have a Medicare Advantage plan. The deductible is $1000, and the out-of-pocket max is nearly $6000. My right knee has been bone-on-bone for many years, but I can't afford knee replacement surgery. Is there any agency or organization that might be able to help me?
