My neurologist today informed me of a new change to Medicare that very few of his patients know about. Starting January 2011, if a doctor injects you with any type of medication--you are responsible to pay not only the office visit charge/co-payment, but also you must pay 20 percent of that drug/medication you are injected with no matter what plan you are on. I am on a Medicare Advantage HMO plan and for a while have gotten occiptal neural blocks and all I have paid is the office visit co-pay. Starting January I will have to paythe office visit co-pay PLUS 20 percent of the cost of the injected drug/medication. SO MAKE SURE YOU CHECK THIS WITH YOUR DOCTOR BEFORE HE DOES INJECTION PROCEDURES AS SOME MEDS ARE VERY EXPENSIVE. I DON'T KNOW HOW IT WILL WORK FOR VACCINES AND IF THEY WILL BE FREE OR BE 20 PERCENT ALSO.
