ICD-10 Code H35.102 – Retinopathy of prematurity, unspecified, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.102 – Retinopathy of prematurity, unspecified, left eye
What it is
This code identifies retinopathy of prematurity affecting the left eye when the stage or severity is not specified. It is used for premature infants with retinal vascular changes documented in the left eye.
Clinical signs
Findings may include abnormal retinal vessel development, peripheral retinal changes, or ophthalmology documentation of retinopathy of prematurity. Clinical features vary; refer to documentation.
When to use this code
Use H35.102 when the record clearly states retinopathy of prematurity in the left eye and does not specify a stage. It also fits when the ophthalmology note confirms the diagnosis but leaves severity undocumented. Code the laterality exactly as documented.
Do not use for
Do not use this code for retinopathy of prematurity in the right eye, both eyes, or unspecified eye laterality. Do not use it when the chart documents a different retinal disorder or when retinopathy of prematurity is not confirmed.
Coding tip
Check the eye laterality and whether the stage is documented before assigning H35.102.
