I've been having problems with Anthem paying as well. ER visit, I pay my co-pay, and then we start getting letters. When all was said and done, Anthem paid $10, my secondary insurance paid $20, and I ate about $270. Around the same time we were notified that my wife's OB and my kid's pediatrician would no longer accept BCBS. Never saw any problems like this with Cigna. Did we get sold a pig in a poke?
