ICD-10 Code H35.111 – Retinopathy of prematurity, stage 0, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.111 – Retinopathy of prematurity, stage 0, right eye
What it is
This code identifies retinopathy of prematurity in the right eye at stage 0, meaning no visible retinal changes are present yet. It is used for infants at risk who are being monitored for this condition.
Clinical signs
Clinical features vary; refer to documentation. Stage 0 generally means no ophthalmoscopic signs of retinopathy are seen, despite prematurity-related risk factors and ongoing surveillance.
When to use this code
Use H35.111 when the provider documents retinopathy of prematurity stage 0 in the right eye. This applies during screening or follow-up exams when the infant has no detectable retinal disease in that eye. Confirm laterality and stage in the note before coding.
Do not use for
Do not use this code if the right eye has a different stage of retinopathy of prematurity. Also avoid it when documentation only says prematurity screening or risk without a confirmed stage 0 diagnosis.
Coding tip
Always code the documented stage and eye separately; if the note is unclear, check documentation before assigning H35.111.
