Aimed at familiarizing mental health practitioners and training faculty with the basics of the ICD-10, this concise, handy guide is an essential read for psychologists, given that the World Health Organization’s International Classification of Diseases (ICD) will become the North American official diagnostic system for mental and behavioral disorders in fall 2014. This book explains why the ICD is the diagnostic system of choice for psychologists, and is the only HIPAA approved code set for billing and reimbursement; traces how the system has been refined over time; describes the taxonomy of diseases in the tenth edition (ICD-10); explains the ICD-10-CM codes for mental health; previews the forthcoming eleventh edition (ICD-11); and contains the ICD-10-CM Full Code Set for Mental and Behavioral Disorders. This primer belongs in the pockets of clinicians and researchers around the world.
