(New York) Just received a collections notice for a 4 year old ER visit. I paid at time of service and had health insurance. The hospital no longer has any record of my bill because of how much time has passed, they said it may have been a separate bill from the ER doctor who may (or may not) have been out if network. I know if I had received this bill 4 years ago I would have paid it, or fought my insurance to make them pay, so I am confident this was never actually sent to me. The complicating factor is that the debt collection company spelled my name wrong on the letter they sent me. They offered in the letter to settle for half price.

Am I liable for a 4 year old bill that I never knew about that nobody can even produce, especially if the name on the supposed debt is not technically mine?

Sorry just read one if your other responses. This debt is outside of the statute of limitations, so how should that affect my response?

Thank you
