CPT 92270: Electro-oculography with Interpretation and Report

CPT code 92270 represents electro-oculography with interpretation and report — a diagnostic electrophysiology test that measures electrical potentials around the eyes to evaluate eye movements and related disorders. Nationally, this procedure supports diagnosis and monitoring of vestibular, neurologic, and ocular motility conditions, informing clinical decisions for ophthalmologists, neurologists, and neuro-ophthalmologists. Its proper coding affects clinical documentation, billing accuracy, and utilization tracking across outpatient settings.

Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines how CPT code 92270 is defined, typical sites of service, and payer coverage themes relevant to diagnostic ocular electrophysiology.

Readers will find: concise benchmarks and coverage notes where available; clinical context explaining when electro-oculography is used; and policy-relevant considerations for documentation and report generation. Data not available in the input is noted where applicable. The summary is intended for a national audience of clinicians, billing professionals, and policy analysts who need a clear, practice-focused reference for CPT code 92270.

Billing Code Overview

CPT code 92270 describes electro-oculography with interpretation and report. The procedure involves measuring the electrical potential between electrodes placed near the eyes to assess eye movements, followed by clinical interpretation of the recorded signals and preparation of a formal report.

Service Type: Diagnostic electrophysiology of ocular motility

Typical Site of Service: Ambulatory clinic or hospital outpatient setting where ophthalmology, neurology, or clinical neurophysiology diagnostic testing is performed

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult referred by an ophthalmologist or neurologist for evaluation of abnormal eye movements, diplopia, vertigo, or suspected vestibular-ocular dysfunction. The patient presents to an outpatient ophthalmology clinic or a specialty neuro-ophthalmology/vestibular testing center. After intake and review of medical history (including prior strabismus, cranial nerve palsy, traumatic brain injury, multiple sclerosis, or vestibular neuritis), surface electrodes are placed at periocular sites to measure the standing corneo-retinal potential and eye movement-related potentials. The provider (an ophthalmologist, neuro-ophthalmologist, or vestibular specialist) oversees electrode placement, conducts calibration and recording during specific gaze and eye movement tasks, interprets electro-oculography waveforms, documents findings, and prepares a formal report. Typical site of service is an outpatient clinic or ambulatory surgical center equipped for diagnostic electrophysiology; performance may also occur in a hospital outpatient department. The service involves patient preparation, electrode application, test execution, professional interpretation, and generation of a written report consistent with 92270.

Coding Specifications

Modifier	Description	When to Use
`26`	Professional component	Use when billing only the physician interpretation/report portion of `92270` separate from technical recording.
`TC`	Technical component	Use when billing only the equipment/electrode setup and recording portion of `92270`.
`50`	Bilateral procedure	Use when testing and reporting bilateral-eye recordings are billed as bilateral by payer rules (rare; verify payer policy).
`52`	Reduced services	Use when the test is partially reduced or not fully completed due to patient intolerance or technical limitations.
`53`	Discontinued procedure	Use when testing is started but discontinued for safety or medical reasons before completion.
`76`	Repeat procedure by same physician	Use when the same provider repeats `92270` on the same day due to technical failure.
`77`	Repeat procedure by another physician	Use when a different provider repeats the test on the same day (note: `77` is not in the provided list; not selected).
`59`	Distinct procedural service	Use only if a truly distinct and separate diagnostic service is performed on the same date (note: `59` is not in provided list; not selected).
`78`	Unplanned return to OR by same physician following initial procedure	Not typically applicable to `92270` but included in provided list; use is rare.
`80`	Assistant surgeon	Not applicable to diagnostic `92270` except in unusual staffing contexts.
