A psychiatric diagnostic evaluation is reported with which specific code?

The designation for a psychiatric diagnostic evaluation in the coding system is represented by code 90791. This code specifically pertains to a comprehensive assessment that includes a clinical interview, relevant history, and any necessary psychological testing or assessments. It is intended for use when a clinician is establishing a diagnosis, thus making it a fundamental code in psychiatric practice.

The importance of accurate coding for such evaluations cannot be understated, as it directly impacts treatment planning and billing practices. This particular code captures the various elements involved in the diagnostic process, ensuring that healthcare providers receive appropriate reimbursement for their services while maintaining the integrity of patient records.

In contrast, the other codes listed have different applications: 90795 is used for a psychiatric diagnostic evaluation with medical services, 90785 indicates a procedure for the treatment of a patient with a complex situation that requires additional resources, and 90834 refers to a psychotherapy session lasting 45-60 minutes. Each of these codes serves distinct purposes that do not align with the straightforward diagnostic evaluation signified by 90791.
