What 92274 covers

Multifocal electroretinography (mfERG) records electrical responses from multiple retinal locations in response to a patterned visual stimulus. An ophthalmologist, often a retina specialist, may use the test to evaluate unexplained central visual symptoms, suspected localized retinal dysfunction, or possible toxic maculopathy. Ophthalmic testing staff typically obtain the responses, which the physician interprets and reports in settings such as an eye clinic or hospital outpatient department.

Choose mfERG when the clinical question concerns localized retinal function; full-field ERG (92273) assesses a broader retinal response. Documentation should identify the reason for testing and include the test findings and interpretation. The code represents the bilateral service, so modifier 50 does not increase payment. The service may be billed globally or split into the professional interpretation with modifier 26 and the technical equipment and staff with modifier TC. The ophthalmology diagnostic multiple procedure reduction applies to the technical component.
