This is kind of off the subject in a way. We received a bill from a collection agency from my wife's former pain specialist. She has not been to that doctor in 3 years and now we are getting a bill, for what ever reason, from several years ago. This doctor was paid by BCBS, then my credit card and was eventually dumped by this doctor when my wife Suzy became eligible for medicare (doctor refused medicare) in which I continued paying for with my credit card, until the doc said that she wanted nothing to do with medicare even though I was paying for treatment, not medicare (except for the meds). Why this has gotten in the hands of a collection agency without my knowledge is beyond me. How does one prove one way or the other what is owed after years have gone by? I was square with this doc and every other doctor.
