Clinical & Coding Specifications

Clinical Context

A 62-year-old patient completes a course of outpatient speech-language pathology for dysphonia following radiation therapy for laryngeal cancer. At discharge, the speech-language pathologist documents persistent functional voice limitations affecting work and social participation despite therapeutic interventions. The therapist completes discharge summary documentation that quantifies voice functional limitation, records progress toward goals, and assigns a final functional status code for reporting.

The clinical workflow includes: initial evaluation with objective and patient-reported measures (e.g., voice handicap index), periodic treatment sessions documenting changes in vocal quality and function, interdisciplinary communication with the treating otolaryngologist and oncologist, and a formal discharge visit where the clinician records the discharge status using the billing code G9173 to indicate voice functional limitation at the end of the episode of care. This code is used for administrative reporting of functional outcomes at discharge from therapy services provided in outpatient therapy clinics, hospital-based outpatient departments, skilled nursing facilities, or home health therapy when voice therapy is delivered.
