<prompt> Human: Sorry for the long post, I hope you can stick with me through it.In February of 2017 we had our first child. And like responsible adults we have health insurance. All went well through delivery and follow up visits. In July we go to the pediatrician who had moved offices, this is important later for some routine vaccinations, because I dont want my kid to die.All is well until we get the bill of almost 1000 after insurance paid 36 for his 3 shots. Now, Ive checked our coverage and we know that preventative care, including vaccinations, are covered 100. I call my insurance and they say it is covered, but that the doctor is out of network. Weve been seeing the doctor for months now and has been in-network, and we had follow up visits after that one that have been covered in-network.Turns out the doctors office billed under the wrong Tax ID number after moving locations. Insurance tells me to tell the hospital to re-file the claim. I do so. Hospital tells me they will re-file. All is well, right? No.3 months later I get another bill that looks the exact same. EOB from the insurer still says it is out of network. I go through the same steps as before. 1 month later I get a letter from collections and I freak out. I call the collections but it turns out theyre an internal collections and it hasnt been sold off. I let them know I dispute the charge and they put it under insurance review. I talk to hospital billing again and they said they figured out the problem and will re-file. All is well, right? NO!I get another bill in the mail today that looks the exact same. Were almost to a year from the original doctor visit and Im at my wits end.Both the hospital and my insurance phones are not available until Monday. I dont know what to do at this point. Its stressing me out and I feel powerless. What options do I have to get this taken care of? Are there other resources in these situations so I dont have to be a middle man between these two corporate behemoths?  <response>: You need to go to your HR rep who handles the insurance plan with the EOBs and bills and ask them to escalate the claim to the insurance for you.
