do health insurance companys check if your student?

i am covered under my dads insurance company as a student and was wondering if insurance companys check if i am still a student? they paid for a medical bill and i am not a student anymore and was wondering if i could get in trouble for them paying the bill while im not a student?

Yes, they check. At least once a year. (If you're having expensive medical claims and/or if they have reason to suspect you aren't a student, then they have the right to ask for proof more often than that. Your dad's employer can also do random dependent eligibility audits.) If (when) they catch you, they will take back the payment from your medical providers for any services you received. And then you will be responsible for repaying the full amount of the bills to your medical providers.
