Steph...
When my husband was hit on his motor scooter by a woman who pulled out in front of him, we had her insurance, Medicare, etc. also to deal with. We kept close track of the bills, and the insurance company payments. Medicare wanted to be sure, of course, that the insurance paid for all they should have. We had to pay upfront, and then listed all those items when the insurance company came to "settle" with us. I went back and sent checks to those hospitals/docs that Medicare had paid since that's what the hospital office/doc's office insisted upon. I kept close track of those checks, too....and when Medicare wrote later about one bill, I sent a copy of the letter I'd sent with the check to the doc's office, noting this was payment for what Medicare had paid, date, etc. and that the doc's office should reimburse Medicare. We never heard another word from Medicare, so assume they took it up with the doc's office...or whatever.
I'm off today to explore the library branch here (we're in S. Texas now until the first of March), and it's always fun to explore a new Library. They're great about having the latest and most popular, of course. For $5.00 they give us "Winter Texans" a library card good for 5 years. That's such a bargain, I also make a donation to their Friends program. I keep telling "Marge"...the gal in charge of this "branch" that they should double or triple, at least that price, but she says they want people to use the place...and they do! For that they get free internet for those condos/RV parks that don't offer that, though I suppose most do now.
