ICD-10 Code H35.162 – Retinopathy of prematurity, stage 5, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.162 – Retinopathy of prematurity, stage 5, left eye
What it is
Use this code for advanced retinopathy of prematurity in the left eye when the retina has reached stage 5, meaning total retinal detachment. It identifies a severe complication of prematurity affecting vision.
Clinical signs
Clinical features vary; refer to documentation. Stage 5 disease is typically confirmed by ophthalmologic examination and documentation of total retinal detachment in the left eye.
When to use this code
Use H35.162 when the provider documents retinopathy of prematurity, stage 5, limited to the left eye. Apply it for encounters where the diagnosis is established, monitored, or listed as an active condition. If laterality or stage is unclear, check documentation before coding.
Do not use for
Do not use this code for earlier stages of retinopathy of prematurity or for unspecified eye involvement. If the record does not confirm stage 5 or left eye, choose a more accurate code or check documentation.
Coding tip
Always verify both stage and laterality in the ophthalmology note before assigning H35.162.
