Thanks all.... I did deposit checks thinking a bill would be arriving soon and money would be in account ready for payment. Endorsement would have worked great had I known I might not get a bill up front. Of course I'd have to hunt down an address for where to send as I did do to get phone number.... I was thinking along lines of auto ins., get estimate, ins. sends me check, I can have repair work done or pocket the cash. Hadn't consider that services were already performed. Good point.... ER surgeon must have requested doc. to attend.... As I mentioned I called doc. several times, seeded grateful I called first couple times but not so much during later calls, maybe wasn't free to talk (on rounds or something).... Had to Google his number each time but last time I noticed his address is close by. Now if I can catch him in his office (I'm wondering when he says "secretary will call" if that means he'll get back to me when he gets in the office (then forgets?).... I'll definitely see to it he gets paid.
