Speaking from experience, I have found the Medicare HMO plans are the best way to go. They offer a prescription drug plan as well as Medical, Hospitalization, Vision Care and Dental. My husband was disabled at 37 years old, so I have been dealing with this for almost 16 years.
Most of the plans have several levels of coverage some ranging from 0 to a small payment for the plan each month. Social Security offers a level of help depending on the financial standing to assist with prescription Copays.
There are many approved companies in the book sent out by Medicare. They key to choosing a plan depends on the coverage you need. My husband is on the Summitt Coventry plan with a 0 pay each month. His primary care is 0 copay, specialist is $20, the prescription plan is in tiers as to whether they are generic or brand and where the medications fall. Most of the common medications are $5.00. The most he pays is $35.00. An ER visit is $50 and they cover ambulance and in hospital stay.
Our choice was based on the plan that offered my husband's physcian on the plan.
