Round hole, right eye

This code signifies a full-thickness defect in the retina of the right eye, typically round or oval in shape, that does not involve the macula. It represents a retinal break that can predispose to retinal detachment if not treated.

Apply this code when documentation specifies a round hole in the retina of the right eye. This diagnosis is often made during a dilated funduscopic examination. Supporting documentation should clearly indicate the location and morphology of the retinal defect.

• Ensure laterality is accurately documented and coded (right eye).
• Differentiate from a retinal tear (H33.31-) or operculated hole (H33.33-), which have distinct coding.
• Code any associated retinal detachment separately, if present.
