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.

- 92270Electro-oculographyWith interpretation and report
- 92270 is electro-oculography, a different electrical test used to assess retinal pigment epithelium function; 92274 records localized retinal responses.
- 92284Dark adaptationDiagnostic examination
- 92284 evaluates dark adaptation, whereas 92274 records electrical responses across multiple retinal locations.
92274 billing questions
How does 92274 differ from full-field ERG 92273?
Multifocal ERG evaluates responses from multiple localized retinal areas, while 92273 measures a broader, full-field retinal response. Select the test that matches the clinical question and the procedure performed.
Does 92274 include the physician's interpretation?
Yes. The global service includes the test's professional interpretation and technical work; modifier 26 identifies the professional component when billed separately.
Can the technical component be billed separately?
Yes. Modifier TC identifies the equipment and staff portion when the technical service is billed separately. The ophthalmology diagnostic multiple procedure reduction applies to that technical component.
Should modifier 50 be reported for testing both eyes?
The code is priced as bilateral, and modifier 50 does not increase payment.
What documentation supports reporting 92274?
Record the clinical reason for evaluating localized retinal function, the mfERG findings, and the physician's interpretation and report. The documentation should support that multifocal ERG was performed rather than a full-field ERG.
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.
