ICD-10 Code H35.179 – Retrolental fibroplasia, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.179 – Retrolental fibroplasia, unspecified eye
What it is
H35.179 identifies retrolental fibroplasia, also called retinopathy of prematurity, when the affected eye is not specified. Use it for abnormal retinal vessel development in premature infants. Check documentation.
Clinical signs
Findings may include abnormal retinal vascular growth, plus evidence of retinal traction or scarring in advanced cases. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record documents retrolental fibroplasia but does not specify the right or left eye. It is appropriate for ophthalmology notes, discharge summaries, or problem lists that confirm the diagnosis without laterality. If the provider names a specific eye, code that laterality instead.
Do not use for
Do not use it for generic prematurity without documented retinal disease. Do not use it when the chart identifies a specific eye or a different retinal disorder. Check documentation.
Coding tip
Confirm laterality in the ophthalmology report before assigning H35.179.
