I am in NJ and my recent meeting with Quest reps informed me that only Horizon HMO must go to LABCORP. As of 3/1/11, all oxford/united healthcare patients who use Quest will not be balance billed for the difference. Any Horizon or BC plans that have a suitcase on their insurance card are able to go to Quest. This applies in NJ.
My Labcorp rep refused to give me an interface b/c I am just solo and it was too costly for them.
