No two offices are the same when it comes to providing for the psychosocial needs of one’s primary care patients. Many offices are integrating mental/behavioral health therapists in their medical home. However, given limited access to psychology and psychiatry resources for children, many primary care providers also are finding themselves taking over the prescribing duties for psychoactive medications. Getting reimbursed for the time and effort that is spent caring for children with psychosocial and mental health issues requires a working knowledge of the diagnostic coding system and local practices of third-party payers. Certain billing codes are meant for primary care providers or psychiatric nurse practitioners while others are restricted for use by psychologists and master’s level therapists. This chapter discusses the reimbursement for mental/behavioral health services in primary care.
