<prompt> Human: My doctor recently sent me a bill for around 200 for services provided almost 2 years ago. Their excuse for the late bill was that they were in the process of a new filingbilling system. I live in Maryland, Do I need to pay this bill since it was only sent to me almost 2 years later?  <response>: The minimum statute of limitations for a written contract in Maryland is 3 years so yes you should pay unless you want to deal with collection agencies.
