Round hole, unspecified eye

This code describes a full-thickness retinal break, specifically a round hole, that has not been further specified as involving a particular eye. These holes are typically small, sharply demarcated, and can predispose to retinal detachment if not monitored or treated.

This code is appropriate when documentation indicates a round hole in the retina but does not specify laterality (e.g., "round hole noted on funduscopic exam"). It should be used when the physician's notes confirm the presence of a retinal round hole without further detail regarding the affected eye.

• Avoid using this code if laterality (right or left eye) is documented; instead, use the more specific H33.321 (right eye) or H33.322 (left eye).
• Do not confuse a round hole with a retinal tear (H33.31-), which typically has a flap or operculum.
• Always review the entire ophthalmology report for laterality and any associated conditions, such as retinal detachment (H33.0-).
