    Clinical & Coding Specifications

    Clinical Context

    A 62-year-old patient with long-standing type 2 diabetes presents to an ophthalmology clinic for an annual diabetic eye evaluation. The visit includes pupil dilation, detailed slit-lamp and fundus examination, stereo biomicroscopy of the retina, and interpretation of findings by the ophthalmologist. The clinician documents the dilated retinal exam, reviews prior retinal imaging and notes, and records the interpretation in the medical record. Typical workflow: pre-visit history and medication review by nursing, visual acuity and intraocular pressure measurement, pharmacologic pupil dilation, dilated retinal exam performed by the ophthalmologist or optometrist, documentation of findings and clinical impression, and communication of results and follow-up plan to the patient. This service is commonly billed when a comprehensive dilated retinal evaluation is performed and interpreted, separate from procedural retinal treatments or imaging-only services.
