They did not tell me when a single week's premium payment did not reach them, even when I called and specifically asked if my premiums were paid and the account was OK! Three months after the one-week loss, I find out while I'm at urgent care for stitches that they canceled my coverage for that week and now urgent care will not treat me until I pay the resulting $400 bill! Then my toddler son went to the ER a year ago for an emergency, the insurance checked out fine in the ER. I got a statement from Aetna saying they covered/paid everything, but a small portion of his EKG. I sent a check out for the next day. Today, a year later, I get a massive $3,500 bill from a collection agency for the ER visit! I called the agency and they said that Aetna never paid a thing!
