GNYHA is dedicated to facilitating communication between hospitals and managed care plans in the greater New York metropolitan region. As part of this commitment, GNYHA has compiled a Managed Care Guide Book that provides accurate and up-to-date contact information for plans and, if applicable, their mental health, dental, vision, pharmacy, and radiology subcontractors. We hope this information will aid in timely and accurate patient eligibility verification, payment, and account follow-up, in particular. If you have any questions, please contact Lauren Hedinger at (212) 506-5514.
