Official Description

Psychiatric diagnostic evaluation with medical services

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 90792 refers to a comprehensive psychiatric diagnostic evaluation that includes medical services. This procedure is essential for establishing a thorough understanding of a patient's mental health status and medical history. During this evaluation, the psychiatrist conducts a detailed psychiatric diagnostic interview, which encompasses gathering a complete medical and psychiatric history from the patient. This process involves performing a mental status examination, which assesses various aspects of the patient's psychological functioning. The psychiatrist may also order laboratory tests and other diagnostic studies, interpreting the results to inform the diagnostic process. Communication with other sources, such as family members or previous healthcare providers, is also a critical component of this evaluation, as it helps to gather additional insights into the patient's condition. The psychiatrist uses this information to establish a tentative diagnosis and to evaluate the patient's capacity to benefit from psychotherapy. The extent of the mental status examination may vary based on the patient's specific condition and needs. During the evaluation, the psychiatrist looks for signs of psychopathology, which can manifest in various ways, including the patient's appearance, attitude, behavior, speech patterns, emotional responses, mood, thought content, perceptions, and cognitive functions. This diagnostic interview is typically conducted when the psychiatrist first sees a patient but may also be repeated for new episodes of illness or in cases of re-admission due to complications. It is important to note that if the psychiatric diagnostic evaluation is performed without accompanying medical services, the appropriate code to report is 90791. However, when medical services are provided alongside the psychiatric diagnostic evaluation, the correct code to use is 90792.

1. Indications

The psychiatric diagnostic evaluation with medical services, represented by CPT® Code 90792, is indicated for various situations where a comprehensive assessment of a patient's mental health and medical history is necessary. This evaluation is typically performed when a patient presents with symptoms that may indicate a psychiatric disorder or when there is a need to reassess a patient's mental health status due to a new episode of illness or complications arising from a previous condition. The following are specific indications for this procedure:

  • Initial Assessment: When a patient is being evaluated for the first time for psychiatric concerns, requiring a thorough understanding of their mental health history.
  • New Episode of Illness: For patients experiencing a recurrence of psychiatric symptoms that necessitate a reevaluation of their mental health status.
  • Re-admission Due to Complications: When a patient is readmitted to a healthcare facility for underlying complications related to their psychiatric condition, requiring a comprehensive assessment.

2. Procedure

The procedure for CPT® Code 90792 involves several critical steps that ensure a thorough psychiatric diagnostic evaluation with medical services. Each step is designed to gather essential information about the patient's mental and physical health.

  • Step 1: Patient History Collection The psychiatrist begins by collecting a complete medical and psychiatric history from the patient. This includes inquiries about past psychiatric treatments, medical conditions, medications, and any relevant family history of mental health issues.
  • Step 2: Mental Status Examination Following the history collection, the psychiatrist conducts a mental status examination. This assessment evaluates the patient's appearance, attitude, behavior, speech, emotional reactions, mood, thought content, perceptions, and cognitive functions to identify any signs of psychopathology.
  • Step 3: Ordering Diagnostic Studies If necessary, the psychiatrist may order laboratory tests and other diagnostic studies to gather additional data that could inform the diagnosis. The results of these tests are interpreted as part of the overall evaluation.
  • Step 4: Communication with Informants The psychiatrist may also communicate with other sources, such as family members or previous healthcare providers, to obtain further insights into the patient's condition and treatment history.
  • Step 5: Establishing a Tentative Diagnosis Based on the collected information, the psychiatrist establishes a tentative diagnosis and assesses the patient's capacity to benefit from psychotherapy or other treatment modalities.

3. Post-Procedure

After the completion of the psychiatric diagnostic evaluation with medical services, the patient may be provided with a treatment plan based on the findings of the evaluation. This plan may include recommendations for psychotherapy, medication management, or further diagnostic testing if needed. The psychiatrist will typically schedule follow-up appointments to monitor the patient's progress and adjust the treatment plan as necessary. It is essential for the patient to adhere to the recommended follow-up care to ensure optimal outcomes and address any emerging issues promptly.
