Medical Billing Dispute - surprise medical bill after insurance

English isn't my first language so bear with me. Has anyone dealt with something like this? I'm not sure what my options are.

surprise medical bill after insurance. I've been dealing with this for about 12 months now and the situation isn't improving.

I have already done some research online but the other party is not cooperating.

Should I hire a lawyer for this or try to handle it myself?

Look, just want to point out — teh statute of limitations might be a factor here. In some states it's as short as 1-2 years. Don't sit on this too long fr fr.
