CPT code 92270: Electro-oculography2026 Medicare rate & RVUs

Medicare pays $125.92 for 92270 nationally in the office. Local office rates run $111.54–$171.91.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 92270 covers

Electro-oculography records changes in the standing electrical potential between the front and back of the eye as lighting conditions change. An ophthalmic technician typically performs the test in an outpatient eye-care setting, while an ophthalmologist, often a retinal specialist or neuro-ophthalmologist, interprets the findings. It can help assess retinal pigment epithelium function in inherited retinal disorders such as Best vitelliform macular dystrophy.

Report 92270 for the bilateral test with interpretation and report. The record should support the clinical reason for testing and include the test findings and physician interpretation. The code is priced as bilateral, so modifier 50 does not increase payment. When billing the professional or technical portion separately, use modifier 26 for interpretation or modifier TC for equipment and staff; billing without either modifier represents the global service. When multiple ophthalmic diagnostic procedures are performed, the multiple-procedure reduction applies to the technical component.

92274Multifocal ERG

92274 evaluates localized retinal responses with multifocal electroretinography; 92270 measures the standing potential as lighting conditions change.

92265Ocular muscle EMG

92265 is needle testing of ocular muscle electrical activity. 92270 is a non-needle electro-oculography study used to assess the standing potential and retinal pigment epithelium function.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
