Diagnosed Mental Health Disorders (DMH)

Summarizes the percentage of members 1 year of age and older who were diagnosed with a mental health disorder during the measurement year.

Note: The measure provides information on the diagnosed prevalence of mental health disorders. Neither a higher nor lower rate indicates better performance.

Why It Matters

In 2022, it was estimated that 23.1%—or more than 1 in 5 adults—had had a mental illness in the past year.1 Mental illness can be defined as mental, behavioral or emotional disorders (excluding substance use) that meet duration and other diagnostic criteria in the Diagnostic and Statistical Manual of Mental Disorders. Among individuals with any mental illness in the past year (59.3 million), approximately half received mental health treatment.1 Untreated mental illness can result in unnecessary disability, loss of productivity, serious health problems and decreased quality of life overall.2
