Is anyone else having trouble with the invoices/receipts that doctor's offices are now providing? Most don't give the date of service any more, just an invoice date, which they will say is always the date of service. And many are now just getting a check, having it paid electronically and giving the check back as the receipt! How is everyone setting the standards for what they will accept and what they won't? We're getting a lot of pressure from participants because the doctors just don't give the standard information any more.
