Summary & Overview
CPT 92548: Computerized Dynamic Posturography Sensory Organization Testing
CPT code 92548 represents computerized dynamic posturography sensory organization testing, a diagnostic procedure that assesses how patients use sensory and motor systems to maintain balance across six standardized testing conditions. Nationally, this test is important for evaluating vestibular dysfunction, balance disorders, fall risk, and for informing rehabilitation or further diagnostic workups. The code covers both technical and professional components, reflecting combined measurement, interpretation, and reporting.
Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. The publication provides a concise view of how the service is categorized, typical sites of service, and common billing modifiers. Readers will find benchmarks and policy-relevant context about coverage patterns and utilization drivers, a summary of clinical indications for testing, and guidance on documentation elements that support medical necessity.

This summary is intended for clinicians, billing professionals, and policy analysts seeking a national overview of CPT code 92548, its clinical role in balance assessment, and the payer landscape relevant to diagnostic posturography services.
Billing Code Overview
CPT code 92548 describes computerized dynamic posturography sensory organization testing performed to evaluate a patient's motor, sensory, and integrative processes used to maintain balance and stability. The service is carried out using six specific test conditions as specified in the CPT descriptor and represents both the technical and professional components of the test.
Service type: Diagnostic balance and postural control testing
Typical site of service: Hospital outpatient departments, specialized balance or vestibular clinics, and rehabilitation centers
Data not available in the input.
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with progressive unsteadiness and frequent falls is referred by their primary care physician to a neuro-otology clinic for objective balance testing. The patient reports dizziness when standing on uneven surfaces and difficulty maintaining balance in low-light conditions. The clinician reviews history, performs physical exam including cranial nerve and cerebellar testing, and determines that computerized dynamic posturography is indicated to evaluate sensory organization and postural control. The patient is scheduled for a single-session computerized dynamic posturography sensory organization test using six standard conditions to quantify the contributions of visual, vestibular, and somatosensory inputs and to guide vestibular rehabilitation planning. The test is performed in an outpatient neurodiagnostics laboratory or specialty clinic by trained technicians under the supervision of a licensed provider, including both technical setup and professional interpretation and reporting, consistent with 92548 representing both technical and professional components. Typical workflow: pretest intake and history, safety screening, equipment calibration, administration of the six SOT conditions, data capture and scoring, immediate clinical review with the supervising provider, and generation of a diagnostic report documenting results and interpretation.
