Summary & Overview
HCPCS G8947: One or More Neuropsychiatric Symptoms
HCPCS Level II code G8947 captures encounters documenting one or more neuropsychiatric symptoms. Nationally, accurate use of this code matters for clinical documentation, care coordination, and reporting of neurobehavioral presentations linked to neurological and psychiatric conditions. Proper coding supports patient tracking across settings and informs population-level understanding of neuropsychiatric burden.
Key payers included in this analysis are 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 billing and documentation. The publication outlines commonly used benchmarks, relevant policy or coverage considerations affecting nationwide reimbursement and reporting, and practical coding nuances for documenting neuropsychiatric symptoms.
This summary equips clinicians, billing staff, and policy analysts with the essential context needed to interpret G8947 usage, understand payer coverage patterns at a national level, and situate the code within broader clinical workflows for neuropsychiatric assessment.
Billing Code Overview
HCPCS Level II code G8947 denotes one or more neuropsychiatric symptoms. The code is used to identify encounters where clinicians document neuropsychiatric manifestations that may accompany neurological or psychiatric conditions.
-
Service type: Assessment and documentation of neuropsychiatric symptoms, including evaluation and monitoring of behavioral, cognitive, emotional, or psychiatric presentations associated with neurological conditions.
-
Typical site of service: Outpatient clinics, neurology or psychiatry practices, behavioral health settings, and integrated care environments where neuropsychiatric evaluation occurs.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult referred to a neurology or behavioral health clinic for evaluation of one or more new or worsening neuropsychiatric symptoms such as agitation, depression, anxiety, hallucinations, delirium, or cognitive/behavioral changes. The patient may be seen in an outpatient neurology office, memory clinic, psychiatric clinic, or an ambulatory geriatric clinic. Initial workflow includes intake by nursing (vital signs, brief mental status), focused history from the patient and caregiver about onset, frequency, triggers and severity of symptoms, medication review, and a standardized cognitive or behavioral assessment (for example, MoCA or NPI-Q). The clinician performs a targeted mental status and neurologic exam, documents neuropsychiatric symptom(s) and impact on function, considers medication-related causes, medical contributors (infection, metabolic disturbance), and comorbid psychiatric disorders. Diagnostic steps frequently include laboratory testing, urine studies, and neuroimaging if indicated. Management planning is documented (behavioral strategies, medication adjustments, referral to psychiatry, caregiver education). Billing uses HCPCS Level II code G8947 to indicate presence of one or more neuropsychiatric symptoms during the encounter. Typical sites of service are outpatient clinics, memory disorder centers, psychiatry clinics, and ambulatory geriatric practices. Common patient scenarios include: a patient with Alzheimer disease presenting with new daytime agitation; a Parkinson disease patient developing visual hallucinations after a medication change; or an older adult with delirium in a clinic after recent hospitalization.
