ICD-10 Code H35.112 – Retinopathy of prematurity, stage 0, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.112 – Retinopathy of prematurity, stage 0, left eye
What it is
This code identifies retinopathy of prematurity, stage 0, in the left eye. Stage 0 means no visible retinopathy is present, but the infant is being followed because of prematurity-related risk.
Clinical signs
Clinical features vary; refer to documentation. In stage 0, the retinal exam shows no signs of active retinopathy in the left eye, though screening may continue because the infant remains at risk.
When to use this code
Use this code when the provider documents retinopathy of prematurity stage 0 specifically in the left eye. It may appear on screening or follow-up eye exams for premature infants. Code only when the record clearly identifies the stage and laterality.
Do not use for
Do not use this code if the chart does not specify the left eye or if a different stage is documented. Check documentation if the note describes bilateral disease, another retinal disorder, or no retinopathy of prematurity diagnosis.
Coding tip
Confirm both the stage and eye laterality in the ophthalmology note before assigning H35.112.
