ICD-10 Code H35.15 – Retinopathy of prematurity, stage 4 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.15 – Retinopathy of prematurity, stage 4
What it is
H35.15 identifies retinopathy of prematurity at stage 4, a severe form involving partial retinal detachment in a premature infant. Use it when the record specifically documents this stage.
Clinical signs
Clinical features vary; refer to documentation. Standard references describe advanced ROP with retinal traction and partial detachment, usually confirmed by ophthalmic exam and staging.
When to use this code
Use this code when the ophthalmologist or neonatal record clearly states stage 4 retinopathy of prematurity. It fits cases with documented partial retinal detachment from ROP, including unilateral or bilateral disease if the record supports it. If the stage is not stated, check documentation.
Do not use for
Do not use it for earlier ROP stages, inactive history, or nonspecific prematurity-related eye findings. If the chart only says “ROP” without staging, do not assume stage 4.
Coding tip
Confirm the stage from the eye specialist’s note before assigning H35.15.
