Summary & Overview
CPT 92540: Vestibular and Balance Testing, Four Tests with Recording
CPT code 92540 represents a bundled diagnostic vestibular and balance testing service in which four specific tests are performed with recording, covering both technical and professional components. This code matters nationally because vestibular testing is a commonly used diagnostic tool for patients reporting dizziness, vertigo, or balance impairment, with implications for specialty care utilization, referral pathways, and reimbursement for combined services. Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find concise benchmarks for utilization and reimbursement patterns, an explanation of the clinical context and expected sites of service, and a summary of relevant billing considerations and common modifiers. The summary highlights what clinicians and billing staff need to know about service composition, typical care settings, and payer coverage trends without making clinical recommendations. Data not available in the input is identified where applicable.

Clinical & Coding Specifications
Clinical Context
A middle-aged patient presents to an otolaryngology or neurotology clinic with several weeks of episodic vertigo, unsteady gait, and intermittent nausea. The patient reports dizziness triggered by head motion and occasional falls. The clinician performs a history and focused neurologic and vestibular examination that suggests a peripheral or central vestibular disorder. To evaluate balance function objectively, the provider orders comprehensive vestibular testing using 92540, which includes four recorded tests of vestibular function (commonly including caloric testing, rotary chair, positional testing with recording, and posturography or electronystagmography/videonystagmography components as available).
The typical workflow: the patient checks in at an outpatient neurotology, ENT, or audiology clinic (or an ambulatory surgical center if testing under anesthesia is necessary). The testing team obtains informed consent, reviews contraindications, and performs the four specified recorded vestibular tests. The provider documents indications, test components performed, patient tolerance, objective measurements, and interpretation. Results inform diagnosis (e.g., vestibular neuritis, benign paroxysmal positional vertigo, Meniere disease, central vestibulopathy) and guide treatment or referral to vestibular rehabilitation therapy.
