ICD-10 Code H35.142 – Retinopathy of prematurity, stage 3, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.142 – Retinopathy of prematurity, stage 3, left eye
What it is
This code identifies retinopathy of prematurity in the left eye at stage 3, meaning abnormal retinal blood vessel growth has progressed to extraretinal fibrovascular proliferation. Use it for the documented stage and laterality only.
Clinical signs
Typical findings include retinal neovascularization extending beyond the retinal surface, often with a ridge or preretinal tissue in a premature infant. Clinical features vary; refer to documentation.
When to use this code
Use H35.142 when the provider documents stage 3 retinopathy of prematurity affecting the left eye. It is appropriate for ophthalmology assessments, screening follow-up, or inpatient records that clearly state the stage and eye. If the note does not specify laterality or stage, check documentation.
Do not use for
Do not use this code for unspecified retinopathy of prematurity, other stages, or disease limited to the right eye. Do not assign it when the record only says “ROP” without stage confirmation.
Coding tip
Confirm both the stage and the affected eye in the ophthalmology note before coding.
