"In modern medicine, diagnosis and treatment is frequently a complex matter requiring the physician to consult with physicians in other specialties. After distilling the information from these consulting physicians, the treating physician comes to his conclusion as to the diagnosis and/or treatment to be rendered. The reports of these consultants are typically contained in the treating physician's filed." Thomas A. Moore, "The Admissibility of Physician's Office Records," NYLJ, June 6, 1995, p. 3, col. 1.
