This is the most inept billing service that I've ever had the misfortune to come across!! For nearly 9 months, I've tried to get across to them my insurance information. Still receiving statements that I will NEVER pay!! They're completely unable to understand that I have Medicare secondary payer and cannot understand that they MUST use the correct billing codes so that they can get paid!! They rate a ZERO!! I will no longer attempt to do THEIR job for them!! I'm done!!
