, I am so sorry you are going through this. Many of us experience this same issue as we cross into medicare as our primary insurance. There are no easy answers to this issue. First I suggest you consider some alternatives. If you have a Medicare part D or G provider, please discuss what your formulary covers. Often your formulary will have options that may be recommended by your doctor and also affordable.
Since we are rapidly coming up on open enrollment, be sure and select your new provider with a formulary that supports the choice of medication for RA. Often, that is the most critical medication we must consider when choosing a prescription medication provider.
If a suitable part D or G provider alternative is not available, consider using Orencia by infusion, which is covered under Medicare part B and may have a less expensive copay again, depending on your Medicare supplemental provider.
If all of that is like hitting a brick wall (even for the most sophisticated, it is daunting), consider obtaining the services of a medicare plan selection advisor. These people act on your behalf to give you advice about supplemental health plan selection and administration. They are free to use and can provide wonderful advice about plan selection. They will want a list of all your medications and help you select a plan to minimize costs.
As always, the cost is only one factor that must be considered when selecting an RA treatment. In all cases, be sure and consult your doctor. After all, the least costly treatment is not always the best measure of success for the treatment of RA.
