UPDATE: So I mailed these in May 6. After mailing them, my HCP said they often needed to show that it was paid before I could get reimbursed, which I didn't have. So that was great.
I've been logging in every day this week to see if the claims had been processed. Of course they hadn't. So I called, and the guy said that I could actually send them electronically by logging in and sending it via the insurance's messaging system. He said he sent it while he was on the phone but it usually takes about 30 minutes to go through. This call had already taken over 15 minutes to get to that point so I let him go. I waited. And waited. No message in the little shitty messaging system. So I call this morning. "oh, you can't send them electronically, but you can send them via fax!" so let's see if I can send a fax online.
