    HCPCS G9174: Other Speech-Language Pathology Functional Limitation

    HCPCS Level II code G9174 reports an other speech-language pathology functional limitation describing the patient’s current status at the outset of a therapy episode and at specified reporting intervals; this code is used for documenting functional communication or swallowing status as part of speech-language pathology assessment and progress monitoring, typically delivered as speech-language pathology therapy in outpatient therapy clinics, rehabilitation centers, home health visits, or inpatient rehabilitation settings.

    Clinical & Coding Specifications

    Clinical Context

    A typical patient is an adult referred to speech-language pathology (SLP) services for functional communication or swallowing deficits following neurologic injury (for example, stroke, traumatic brain injury), progressive neurologic disease (for example, Parkinson disease), or head and neck cancer treatment. At the start of an SLP episode of care the clinician performs standardized functional communication and/or swallowing assessments and documents baseline functional limitations. The clinician then records the current status at regular reporting intervals (for example, every 30 days or at discharge) to track change over the episode. Typical workflow: initial evaluation and baseline functional limitation documentation; development of a plan of care with measurable functional goals; periodic skilled SLP treatment sessions; interval re-assessments using the same functional limitation measures; and completion/discharge summary noting final status and change from baseline. Typical site of service includes outpatient rehabilitation clinics, hospital inpatient rehabilitation units, skilled nursing facilities, home health settings, and outpatient hospital departments. The service type is speech-language pathology functional status reporting during a therapy episode, using standardized functional limitation descriptors and current-status documentation for reporting intervals.
