What 92273 covers

Full-field electroretinography (ERG) measures the retina’s electrical response to flashes of light, commonly using electrodes on or near the eye. Ophthalmic staff typically acquire the recordings in an eye clinic or diagnostic testing area, while an ophthalmologist interprets the waveforms and reports the findings. The test helps assess generalized retinal function in conditions such as inherited retinal dystrophies or unexplained visual dysfunction; it is distinct from imaging that depicts retinal anatomy.

Report the test when the full-field recording and interpretation are performed, and document the clinical question, testing protocol, recorded responses, and physician interpretation. CMS recognizes professional and technical components: modifier 26 identifies interpretation, modifier TC identifies equipment and staff, and an unmodified claim represents the global service. The ophthalmology diagnostic multiple-procedure reduction applies to the technical component when multiple applicable tests are billed. The code is priced as bilateral, so modifier 50 does not increase payment.
