I know I said that they were professional and all, but the other day we received a bill for what the insurance wouldn't pay.  It came in a decent envelope, but then we opened it.\n\nPlain sheet of paper with printing.  No tear-off portion, no return envelope (not to mention return postage - I wouldn't expect that from anyone).  Just a sheet, badly folded, printed out on a cheap printer.\n\nSo much for professional.  I guess that only extends to examinations - and presumably procedures.  Definitely not to the billing department.  We get a lot of medical bills since we started buying our own insurance, and this is definitely the cheapest of the bunch.\n\nI get that it's only a few cents for an envelope and all - but it can't cost them much more to have some reasonably pre-printed invoices with tear-off return portions, much less a return envelope.  It would just make for a nicer experience, you know?
