19 year old's medical debt.
I am a 19 year old full time college student. I still live at home with my parents and only have a part time job. I recieved a call while at work from a collection agency over a medical bill from last year. I am still covered by my parent's insurance, and I'm not sure if I am responsible for this debt. I was unaware that this debt even existed until this call took place. My questions are:
1) am I responsible for this debt
2) how do I know this debt is real, considering its from last year and i knew nothing of it prior to the call
Thank you for your time
