Retinopathy of prematurity, stage 3, left eye

This code signifies a severe stage of retinopathy of prematurity (ROP) affecting the left eye, characterized by the growth of abnormal blood vessels into the vitreous humor. This neovascularization can lead to retinal detachment and significant vision impairment if left untreated.

Apply this code when documentation confirms a diagnosis of Stage 3 ROP in the left eye, typically in premature infants. Supporting documentation should include ophthalmological examination findings detailing the presence of extraretinal fibrovascular proliferation.

• Ensure laterality is accurately documented and coded; do not use unspecified laterality codes if the left eye is specified.
• Distinguish carefully between ROP stages 1, 2, and 3, as well as threshold vs. prethreshold disease, as these have distinct codes.
• Always review the full ophthalmology report for precise staging and laterality to avoid miscoding.
