CPT 92544 Ocular Motility — Reimbursement & Policy

CPT code 92544 represents a diagnostic test that assesses bidirectional eye movement using foveal or peripheral stimulation and documents the recorded responses. Nationally, this code is used to evaluate ocular motility and vestibular-related eye movement disorders, informing diagnosis and management of conditions that affect gaze stability, nystagmus, and related visual-vestibular function.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides a concise overview of clinical context, coding considerations, and payer coverage patterns where available. Readers will find benchmarks on utilization and reimbursement (where available), common clinical indications for the test, and notes on typical service settings.

The piece offers practical, policy-relevant context for clinicians, billing staff, and administrators: how the service is described clinically, where it is typically performed, and what types of operational and documentation issues commonly arise. Data not available in the input is noted where applicable. The focus is national in scope and intended to support accurate coding, billing clarity, and administrative understanding of CPT code 92544.

Billing Code Overview

CPT code 92544 describes an examination in which the provider administers a test to assess the bidirectional movement of the eyes with foveal or peripheral stimulation and records the results. This service evaluates ocular motility and gaze stability by observing eye movements in response to specified visual stimuli.

Service type: Ocular motility and vestibular-related eye movement testing
Typical site of service: Outpatient clinic, specialty ophthalmology or otolaryngology clinic, or hospital outpatient department

Clinical Context

A 62-year-old patient presents to an outpatient ophthalmology clinic with new onset intermittent vertigo, oscillopsia, and imbalance following a suspected cerebrovascular event. The neuro-ophthalmologist performs a clinical history and physical exam, then schedules ocular motor testing to evaluate eye movement control. During the visit the provider administers a bidirectional eye movement test using both foveal (fixation target) and peripheral stimulation while recording responses with either video-oculography or infrared eye movement recording equipment. The procedure documents smooth pursuit, saccades, gaze-holding, and any nystagmus in horizontal and vertical planes. Results are used to differentiate peripheral vestibular causes from central neurologic causes and to guide further imaging, vestibular testing, or rehabilitation.
