There are certain procedures that require a big co-pay. I don't have the $$$$ like many others. I can't have these procedures done. Now, if I have to call the doctor, I am charged for a phone call!!! I can't ask any questions. Never get the Doc, always "he will call you when he can". When he does, I am charged for a phone visit.
After having a colonoscopy last spring, I had to pay $250.00. No follow thru by the MD. I filled the prescription that cost $979.00 and it was making me sick. I called the office and the Doc prescribed another RX instead. This one was only $800.00. I never filled it.

My symptoms have almost disappeared without any side effects without the RX. Maybe I'm being foolish but it is a case of MD, hospital and drug company squeezing us for every penny.

I was injured in September (torn meniscus, left knee. Saw the Ortho doc(with $250.00 co-pay) they took a look at my knee, did an xray and told me to sit it out, exercise and see a therapist. Phooey. Another co-pay.
If you are on Medicare, it is not a panacea. There are so many loopholes into which you may fall.

As to eye, dental, hearing..there is nothing.
It also bugs the heck out of me, there is never a follow thru by the doctors office. Once you pay, that is it. If I have to call with a question, I'm charged.

Annual exam in April, that is free under Medicare. Any problems? You are on your own after that, even if the Doc sends you to a specialist, the co-pay kicks in.

No way is Medicare a great system. (Just my opinion)
