Common Language Description

The CPT® Code 90801 refers to a Psychiatric Diagnostic Interview Examination, which is a comprehensive assessment conducted by a qualified mental health professional. This procedure involves a detailed interview aimed at gathering a complete medical and psychiatric history from the patient. During this examination, the provider evaluates the patient's mental status, which includes assessing cognitive functions, emotional state, and behavioral patterns. Additionally, the provider may seek information from outside sources, such as family members or previous healthcare providers, to gain a more thorough understanding of the patient's condition. The ultimate goal of this diagnostic interview is to formulate a precise diagnosis and develop an appropriate treatment plan tailored to the patient's needs. It is essential that the provider documents their findings, including the opinion formed and the proposed plan of action, to ensure continuity of care and facilitate future treatment decisions.

1. Indications

The Psychiatric Diagnostic Interview Examination (CPT® Code 90801) is indicated for patients who present with a variety of mental health concerns. This procedure is typically performed when there is a need to assess the patient's psychological state comprehensively. The following conditions may warrant this examination:

  • Psychiatric Symptoms Patients exhibiting symptoms such as anxiety, depression, mood swings, or psychosis may require a thorough evaluation to determine the underlying issues.
  • Behavioral Concerns Individuals displaying problematic behaviors, such as aggression, withdrawal, or significant changes in behavior, may benefit from this diagnostic interview.
  • History of Mental Illness Patients with a known history of mental health disorders may need a reevaluation to update their diagnosis and treatment plan.
  • Substance Abuse Issues Those struggling with substance use disorders may require a comprehensive assessment to address co-occurring mental health conditions.

2. Procedure

The procedure for the Psychiatric Diagnostic Interview Examination involves several key steps that ensure a thorough assessment of the patient's mental health. Each step is crucial for gathering the necessary information to formulate an accurate diagnosis and treatment plan.

  • Step 1: Patient Interview The provider begins by conducting a structured interview with the patient. This interview is designed to elicit detailed information about the patient's medical and psychiatric history, including any previous diagnoses, treatments, and responses to those treatments.
  • Step 2: Mental Status Evaluation Following the initial interview, the provider performs a mental status examination. This evaluation assesses various aspects of the patient's cognitive and emotional functioning, including appearance, behavior, mood, thought processes, and insight.
  • Step 3: Gathering Additional Information The provider may also reach out to outside sources, such as family members or previous healthcare providers, to obtain supplementary information that can provide further context to the patient's condition.
  • Step 4: Documentation After completing the interview and evaluations, the provider documents their findings meticulously. This documentation includes the patient's history, mental status evaluation results, and the provider's clinical opinion regarding the diagnosis and proposed treatment plan.

3. Post-Procedure

After the Psychiatric Diagnostic Interview Examination, the provider will typically discuss the findings with the patient, explaining the diagnosis and the rationale behind the proposed treatment plan. It is essential for the patient to understand the next steps in their care, which may include therapy, medication management, or referrals to other specialists. Follow-up appointments may be scheduled to monitor the patient's progress and make any necessary adjustments to the treatment plan. Additionally, the provider may recommend resources or support systems to assist the patient in their recovery journey.
