<prompt> Human: My daughter was born 5-25-2015 when she was covered under the health plan of Nevada. Sense then her mother and I got married 6-19-2016. I added my wife and daughter to my health insurance plan after the wedding. Now Im receiving a 47k bill from my health plan for the birth of our daughter from back in 2015.. How is my insurance plan billing me for my daughters birth from over a year ago when she was covered under another plan? Weve checked with the hospital and they say her bill was already paid for through the health plan of Nevada. Please help. Thank you. EDIT:Some info to help clarify the situation.The mother of my daughter was and still is a full time nursing student paying out of pocket. She received Medicaid when she was pregnant and for the birth. After the birth My daughter she also received medicaid. My daughter had the hiccups during birth and inhaled some bacteria and was sent to the NICU for 7 days on antibiotics. Being first time parents and after several exhausting weeks I missed the 30 day window to add my daughter to my own insurance. Now that we are married I was able to add them both to my insurance.  <response>: I dont know why your plan is billing you. If Medicaid health plan of Nevada? paid for it, they will come after you for reimbursement. 47,000.00 is a hell of a lot for having a baby though.
