My FIL's insurance company has denied claims for all or part of two of his recent hospital visits. As he has recently passed away, DH is trying to speak to them to clear this up so the bills will get paid. Two bills have already arrived, with more on the way. The insurance company will only accept one of two forms - Executor of Estate or Small Estate Affadavit. As there is no estate for this individual and will not go to probate (there's a trust which is it's own entity), neither document will exist. Has anyone else run into this, and what document did they accept in lieu of the above?
I think I'd send a letter to the legal department of the insurance company and ask how to establish the fact that your are authorized to speak with them.
Hospital and doctors can get the bills out faster than insurance companies can process them. Meanwhile, bills may be forwarded 'for information purposes' to the patient/estate. If your FIL passed recently, I would just wait it out.
AND sorry about your loss, this frustration on top of it is discouraging.
