In have battled 3 serious diseases for 4 years and been on medicare the past 2. There has been NO problem whatsoever to get the treatment I needed and you can go to whatever doctor you wish. There are some treatments that need to be justified to medicare but that is also true of ALL private insurance.
What is going to happen in the future if our healthcare system is changed is a matter of conjecture. But at this time anyone on medicare should not have any more problem getting needed care than someone on private insurance.
In addition, I have paid almost nothing to doctors and hospitals and labs since going on medicare. Of course I have a drug plan and a medigap plan which I pay but overall it is MUCH cheaper than the private insurance I had and I am getting the same care.
If you are talking about medicaid that is a different subject and varies from state to state. There is NO funding of medicaid and never has been. Medicare is funded with payroll taxes but there is no such tax to fund medicaid.
There are many state assistance programs as well as drug assistance programs and I see that others have listed some sites.
