Mom Being Sued For Ambulance Ride That Never Happened

This happened in Colorado

Back in 2019 while I was a minor when at a clinic they told me I needed to visit an ER. they offered an ambulance to bring me to the ER or my mom could drive me there. We opted for my mom just to drive me.

Fast forward 2025 my mom tells me she was served papers from a dept collection agency for $4000 and some change for an ambulance ride from clinic to ER. My mom claims she never received a bill before it went to collectors. With an ambulance bill that high it sounds like it never went through insurance, which makes sense because it never actually happened.

My mom can’t afford the bill let alone an attorney. What are the options here? I really appreciate any advice.
