Doctor billing years later for covered costs

[dknisely]

What is the name of your state? PA
Yesterday I received a bill from a doctor for services from 2001-2003. This is no longer my primary care physician. It has listed dates of services, the fact that I paid my copay, what the insurance company paid and what adjustments were made. It still lists that I owe $190. Since they aren't detailed bills, I don't know what the services were. I am assuming they were for regular doctor's visits due to sinus infections, etc and there should have been nothing provided that my insurance company would not pay for. Can a doctor bill for these services, even though they have a contract with an insurance company to provide care with the agreement that a patient is only responsible for the copay? And can they bill me now, 5 years later, even though no previous bill was sent?

That depends on what the services were and on the exact terms of your insurance policy. You're only guessing what these services were; if the insurance company denied the claims for some reason, you don't get the services for free (or for the copay amount). You still owe the balance.

And can they bill me now, 5 years later, even though no previous bill was sent?

Unless state law says otherwise, yes.
