<prompt> Human: I turned 26 in early December and knew I would soon be off of my parents coverage. My companys insurance policies start mid-year, so I had to file paperwork for them to allow me to switch over. My company asked for a letter from my dads company stating when I would no longer be covered by their plan. The letter states that my coverage ends with their plan year at 12312017 on the year of my 26th birthday. As such, my companys insurance only began 112018.From comparing the two plans, my dads offered the better Dental Package. I decided to rush and get my wisdom teeth removed in December while I was still under their plan. or so I thought? I paid my 450 copay and got the work done on 12282017.Now, its 2018 and my dads dental plan says that I wasnt covered under them when I had the surgery and I have no idea what to do. Theyre telling me I owe the total amount 2,125 out of pocket. Im mortified. What can I do? Im worried that the letter I received only referred to their health package coverage and maybe the vision and dental packages ended on different dates? Is this a thing? If the dental coverage ended exactly on my birthday, then I wouldve not been covered by ANY plan on the day I had my teeth removed. Has anyone ever been in a similar situation?Assistant: Your dad needs to talk to his HR and find out when your dental coverage actually expired. Plans differ in how they handle turning 26. Sometimes your coverage ends on your birthday; sometimes your coverage continues until the end of the month in which you turn 26.Human: So theres a good chance the different plans had different end dates for me?  <response>: Are they telling you that you were not covered under the plan period or that just your wisdom teeth extraction wasnt covered? In some cases dental insurance wont cover having your wisdom teeth removed. In those instances your medical insurance would cover it.
