Summary & Overview
HCPCS G9164: Spoken Language Expression Functional Limitation at Discharge
HCPCS Level II code G9164 captures a patient’s spoken language expression functional limitation at discharge from therapy or at the end of reporting. The code identifies functional communication outcomes rather than a discrete procedural intervention, and it supports documentation of therapy results, quality measurement, and continuity of care across settings. Nationally, such discharge-status functional codes are important for outcome reporting, payment reconciliation in some programs, and clinical handoffs.
Key payers covered in this publication include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical role, the typical service and sites where it is applied, and context for how discharge functional-status codes are used in therapy workflows and reporting. The publication summarizes benchmark considerations and policy context relevant to nationwide use, including how discharge-status functional codes inform quality measurement and claims documentation. Data not available in the input is noted where applicable, and the report does not make clinical recommendations or prescribe billing actions.
Billing Code Overview
HCPCS Level II code G9164 describes a spoken language expression functional limitation recorded as a discharge status at discharge from therapy or to end reporting. This code is used to document the patient’s spoken language expression ability at the point of discharge from speech-language pathology services or at the end of a reporting period.
Service type: Speech-language pathology — functional communication assessment at discharge
Typical site of service: Outpatient therapy clinics, hospital-based speech-language pathology services, and other rehabilitative therapy settings where discharge functional status is recorded

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult who completed an episode of speech-language therapy following a stroke with expressive language deficits (aphasia) or a progressive neurologic disorder affecting spoken language. At discharge, the speech-language pathologist performs a final functional assessment of spoken expression to document the level of limitation and to complete required reporting for quality measures and payer documentation. The workflow includes reviewing baseline and interval assessment scores (e.g., Western Aphasia Battery, Boston Naming Test, functional communication measures), conducting a standardized or clinician-rated spoken expression task (naming, phrase/sentence production, conversational sample), assigning a discharge functional limitation level, documenting progress toward goals, and communicating results in the discharge summary. This reporting supports continuity of care for primary care, neurology, or long-term care teams and meets payer and regulatory requirements for therapy discharge status reporting.
