As psychological psychotherapists, we have obtained an expert's certificate in behavioral therapy and therefore are in the doctor's register “Kassenärztliche Vereinigung Nordrhein” (in accordance with § 4 of the Medical Acceptance Ordinance). The costs for outpatient psychotherapeutic treatment are calculated according to the rates for psychological psychotherapists formally known as Gebührenordnung für Psychologische Psychotherapeuten (GOP).
