Most Commonly Used Diagnosis Codes in Mental and Behavioral Health
For mental health providers in the United States, the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) is the official set of recognized mental health diagnoses. Developed and maintained by the American Psychiatric Association (APA), DSM-5 includes nearly all of the guidance a provider may need to diagnose any recognized mental disorder.
While DSM-5 and ICD-10 are maintained by different organizations, the diagnostic codes you find in DSM-5 are actually ICD-10 codes. DSM-5 references ICD-10 codes and provides a comprehensive list of diagnostic criteria for each recognized mental disorder. Because DSM-5 and ICD-10 aren’t strictly related, there may occasionally be a disconnect between diagnoses in the two sets. However, one goal of a recent revision to DSM-5 was to better align diagnostic criteria and coding with the ICD-10.
All ICD-10 codes start with a single letter, followed by three or more numbers. The most commonly used ICD-10 codes for mental health disorders are clustered as F codes. F codes are further broken up into the following categories:
| F00–F09: codes for organic, including symptomatic, mental disorders |
| F10–F19: codes for mental and behavioral disorders due to psychoactive substance abuse |
| F20–F29: codes for schizophrenia, schizotypal, and delusional disorders |
| F30–F39: codes for mood disorders, depression, and bipolar disorders |
| F40–F49: codes for neurotic, anxiety, stress-related, and somatoform disorders |
| F50–F59: codes for behavioral syndromes associated with physiological disturbances and physical factors |
| F60–F69: codes for disorders of adult personality and behaviors |
| F70–F79: codes for intellectual disabilities |
| F80–F89: codes for pervasive and specific developmental disorders |
| F90–F98: codes for behavioral and emotional disorders with onset usually occurring in childhood and adolescence |
| F99: Unspecified mental disorder |
| G codes for mental health: codes for the disease of the nervous system |
| Z codes for mental health: codes for factors influencing health status and contact with health services (includes 2018 No Diagnosis or Condition code) |
