I don't think anyone is saying you have to get a new card very year if yours doesn't have an expiration. What I am at least saying is that you need to have a real doctor patient relationship.

Ask the DoH if an authorization from 1999 without an expiration date, from a doctor you no longer see, who is no longer up to date on your current medical needs will still be valid. That's the question. Not whether or not the paperwork has to be redone every year, that isn't needed, but does that paperwork need to be from a current doctor who is treating you?
