Retinopathy of prematurity, stage 4, right eye

This code represents a severe form of retinopathy of prematurity (ROP) affecting the right eye, characterized by partial retinal detachment. It signifies a progression beyond earlier stages, indicating significant vascular and retinal abnormalities in a premature infant.

Use this code when documentation specifies stage 4 ROP in the right eye of a premature infant. This diagnosis is typically made by an ophthalmologist based on funduscopic examination findings. Supporting documentation should clearly indicate the stage and laterality.

• Ensure the laterality (right eye) is explicitly documented and matches the code.
• Distinguish from stage 4 ROP in the left eye (H35.152) or bilateral (H35.153).
• Code any associated conditions, such as prematurity (P07.-), as additional diagnoses.
