ICD-10 Code H35.10 – Retinopathy of Prematurity, Unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.10 – Retinopathy of prematurity, unspecified
What it is
H35.10 identifies retinopathy of prematurity when the record does not specify the stage or other details. Use it for premature infant retinal disease documented without further classification.
Clinical signs
Findings may include abnormal retinal vascular development in a premature infant. Clinical features vary; refer to documentation for the specific eye findings or stage.
When to use this code
Use this code when the provider documents retinopathy of prematurity but does not state a stage, laterality, or other qualifying detail. It also fits when the note confirms the diagnosis and no more specific code is supported. Check documentation if the record mentions a different retinal disorder.
Do not use for
Do not use it for other retinal diseases, suspected retinopathy without confirmation, or cases where a more specific retinopathy of prematurity code is documented. Check documentation.
Coding tip
Query the provider for stage or additional detail if the note supports a more specific H35.1- code.
