Retinopathy of prematurity, stage 2, right eye

This code signifies a specific stage of abnormal blood vessel development in the retina of premature infants, affecting the right eye. Stage 2 retinopathy of prematurity (ROP) is characterized by the presence of a raised, thick, and irregular ridge separating the vascularized from the avascular retina. This stage indicates a progression from the demarcation line seen in Stage 1, but without the extraretinal fibrovascular proliferation of more advanced stages.

Use this code when documentation clearly indicates a diagnosis of Stage 2 retinopathy of prematurity affecting the right eye. This diagnosis is typically made by an ophthalmologist during a retinal examination of a premature infant. Supporting documentation should include the stage of ROP and the specific eye affected.

• Always confirm the specific stage of ROP and the affected eye(s) from the ophthalmologist's documentation.
• Do not confuse Stage 2 ROP with other stages (e.g., H35.12- for Stage 1, H35.14- for Stage 3).
• Ensure laterality is accurately captured; separate codes exist for the left eye (H35.132) and bilateral involvement (H35.133).
