Reporting Electroretinography: Full-Field, Multifocal, and Pattern Methods (August 2024)
August 2024 pages 5-8 Reporting Electroretinography: Full-Field, Multifocal, and Pattern Methods For the CPT 2019 code set, code 92275 was deleted, and two new codes (92273, 92274) were established in the Ophthalmology subsection of the Medicine section. In addition, Category III code 0509T was created to report one of three methods of electroretinography (ERG) testing (full field [ffERG], multifocal [mfERG], and pattern [PERG]). Code 92273 describes ffERG, which measures the overall retinal response to light stimulation. Code 92274 describes mfERG, which provides retinal response data for multiple locations in the retina. Both codes 92273 and 99274 are used for...

Article Overview
This CPT Assistant article explains how electroretinography-related services are organized across CPT and Category III coding, with emphasis on the broad reporting framework for full-field, multifocal, and pattern testing. It is intended for ophthalmology coders, billers, and clinicians who document and report retinal and optic nerve testing. The article also addresses related terminology, associated ophthalmic service references, and typical clinical contexts in which these tests may be discussed.
Why This Topic Matters
Electroretinography is reported using multiple code types and method-specific terms, so clear understanding of the article helps support accurate ophthalmology documentation and claim reporting.
Article Sections
-
Coding background and ERG method overview
Introduces the article’s focus on electroretinography reporting in ophthalmology and summarizes the major testing methods discussed. It also places the topic in the context of CPT and Category III coding.
-
Code references and related ophthalmic service notes
Lists the primary electroretinography coding references and points to a few related ophthalmic procedures. This section frames the article’s scope around reporting and terminology.
-
Purpose of ERG testing and method categories
Describes the general clinical role of electroretinography and distinguishes the broad testing approaches covered in the article. It emphasizes the different areas of retinal function referenced in the discussion.
-
When the methods may be reported
Summarizes the kinds of clinical situations discussed for the article’s ERG methods. It provides broad context for the testing scenarios addressed without detailing decision rules.
-
