CPT code 92134 represents computerized diagnostic imaging of the retina in the posterior segment with professional interpretation and a written report. This ophthalmic diagnostic procedure is widely used to evaluate retinal structure for conditions such as macular degeneration, diabetic retinopathy, retinal detachments, and other posterior segment pathology. Nationally, the code matters because retinal imaging drives diagnosis, monitoring, and treatment decisions and is a frequent billable service in outpatient eye care.
