I just checked my drug plan's formulary, and sure enough, Deplin is not covered by my plan.

My PNP told me she thought most elderly people (my mom is 84) could really benefit from a cognitive enhancer. But most elderly on medicare and my mom could not get Deplin unless her coverage paid. So that is out. It just seems contradictory. If Deplin can help most elderly, why not make it available to that population? Maybe its benefit is not so clearcut. Perhaps it is still experimental?
