[dheera]

Had a echocardiogram that I was told would be covered but insurance didn't pay, and they balance billed me for $5K. I never paid. Got handed to debt collectors. Wrote to them saying it isn't my debt and to cease contacting me.

If they take it to court I'll lawyer up and fight.

In any case, I gave neither debt collectors nor medical office my residential address or mobile number. I suggest you NEVER give your residential address to medical offices either, or they'll happily tell debt collectors where you sleep. Which personally I think should be a HEPA violation but apparently it isn't.

Give them a virtual mailbox or office address where you can receive mail.
