Hospital bill 3 years later!

USA healthcare is a joke! I had a MVA in late 2017 and ended up having to do ankle surgery to repair multiple tears. My auto and health insurance info was provided before the procedure to the surgeon (my treating podiatrist) and confirmed at the hospital at the time of the procedure. Today I received this! What the actual fuck! This is also the first bill I have gotten regarding this. I’m definitely calling my lawyer tomorrow morning. I’m freaking the fuck out! I recently filed for bankruptcy and it’s done, case closed and all debt cleared as of today! Ffs I have shitty luck. Is this even legal? Guess I’ll find out tomorrow. FUCK!!! Update: My lawyer has proof of all my insurance payments and is getting an itemized bill to figure out why that amount is so insane. Due to the statute of limitations I’m not held liable for anything. This was a roller coaster of emotions.
