Prices And Cost Sharing For Psychotherapy In Network Versus Out Of Network In The United States.

Patients in the US are more likely to receive out-of-network behavioral health care, including treatment for mental health or substance use disorders, than they are to receive other medical and surgical services out of network. To date, out-of-network and in-network trends in the prices and use of ambulatory behavioral health care have been seldom described. Here we compare levels and growth of insurer-negotiated prices (allowed amounts), patient cost sharing, and use of psychotherapy services in network and out of network in a large, commercially insured US population during 2007-17. For both adult and child psychotherapy, prices and cost sharing were substantially higher out of network than they were in network. These gaps widened during the eleven-year period. Prices and cost sharing for in-network psychotherapy decreased during this period, whereas prices and cost sharing for out-of-network psychotherapy increased. Use of adult and child psychotherapy increased during this period, driven by growth of in-network rather than out-of-network use. The increasing gap in prices and cost sharing between out-of-network and in-network psychotherapy, viewed in the context of a shortage of behavioral health providers who accept insurance, may limit access to ambulatory behavioral health care.
