Diagnostic Coding and ICD-10-CM
The ICD-10 is the World Health Organization’s (WHO) current version of the International Classification of Diseases, used worldwide to capture information about all diseases and health conditions, not just mental health. The ICD-10-CM (10th Revision — Clinical Modification) is a modification for use in the United States, and is the required code set for billing purposes as of Oct. 1, 2015.
The American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM) is widely used for training and diagnostic purposes across mental health professions in the U.S. and contains ICD-9-CM and ICD-10-CM codes as well as diagnostic criteria.
Since Oct. 1, 2015, psychologists and other health care professionals have been required to use the ICD-10-CM for diagnostic coding and billing purposes. The following information provides practical information on the ICD-10-CM and an easy-to-use crosswalk of the codes.
