Summary & Overview
HCPCS G9743: Psychiatric Symptoms Not Assessed
HCPCS Level II code G9743 indicates encounters in which a patient presents with psychiatric symptoms that were not assessed and no specific reason is documented. Nationally, accurate use of this code affects behavioral health reporting, quality measurement, and claims adjudication because it captures instances where assessment did not occur despite identified psychiatric concerns. Proper identification of such encounters supports care continuity and administrative transparency.
Key payers covered include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the code’s clinical context, typical sites of service, and implications for documentation and billing. The publication summarizes benchmarks where available, notes relevant policy considerations affecting coverage and coding practice, and provides clinical context to clarify when the code is applicable.
This analysis is intended for a national audience of clinicians, coding professionals, and policy analysts seeking a concise reference on the purpose and use of HCPCS Level II code G9743, including what the code represents, which payers are addressed, and what aspects of billing and documentation to consider when psychiatric symptoms are identified but not assessed.

Clinical & Coding Specifications
Clinical Context
A middle-aged patient presents to an ambulatory behavioral health clinic for a scheduled psychiatric follow-up. During triage and evaluation the patient is unable or unwilling to participate in a psychiatric symptom assessment due to acute agitation, severe cognitive impairment, language barrier without an available interpreter, or refusal. The clinician documents that psychiatric symptoms were not assessed and records the specific reason in the chart (e.g., patient refusal, altered mental status, safety risk, or sensory impairment). The clinical workflow includes triage, brief safety screening (e.g., suicidal/homicidal risk), noting inability to perform a full psychiatric assessment, providing immediate safety interventions if needed, arranging alternate care (emergency department transfer, family contact, interpreter services, or deferred assessment), and documenting the reason and next steps. Billing uses G9743 when psychiatric symptoms were not assessed and the reason is not otherwise specified.
