Phone id'd caller as "Coventry" (my health insurance carrier).  Caller wanted to send a nurse practitioner to do "an evaluation".  When I asked what's to evaluate, caller listed things that Coventry already has access to (my medications, history, etc).  They also claimed to have sent me a letter telling me they would call. When asked where they sent it, they supplied an old address that had been updated to Coventry over 2 years ago.  The caller seemed to be following a script and my questions seemed to put him off.  After a couple of minutes, caller hung up.  This seems to be a phone solicitor posing as my insurance company.
Phone service provider for the caller's phone is Metro in Grand Island, Nebraska.  I do not know if Coventry has an office there, but will check.
