Look at
Sign up/change plans | Medicare.gov and similar sites. This one will let you find local plans. Do not go medicare only. You will pick up about 20% of additional costs. Don't know which is better -supplement or advantage. I would lean toward advantage. The quality of your service might depend more on the quality of the employees than the plan. Try and identify the doctors you will want and make sure they are on the plans you pick and accepting new clients. I would go to a GP now and see what else might be wrong and he might be able to give you help on finding doctors.
