90815 is used for comprehensive psychiatric diagnostic evaluations involving medical services, typically performed by psychiatrists. In contrast, 90834 is a psychotherapy session code for individual therapy without medical evaluation. Both are used in outpatient mental health settings, but 90815 involves a medical component, making it more extensive. Understanding these differences helps providers select the appropriate code for billing and documentation purposes.
