ICD-10 Code H35.172 – Retrolental fibroplasia, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.172 – Retrolental fibroplasia, left eye
What it is
This code identifies retrolental fibroplasia affecting the left eye. It is used when the condition is documented specifically in that eye.
Clinical signs
Clinical features vary; refer to documentation. Standard references describe abnormal fibrovascular tissue behind the lens, often associated with retinal changes in affected eyes.
When to use this code
Use H35.172 when the provider documents retrolental fibroplasia in the left eye and laterality is clear. You may also use it when the diagnosis is confirmed in the chart, even if the note is brief.
If the record only says retrolental fibroplasia without eye laterality, check documentation before coding. Do not assume bilateral or unspecified disease.
Do not use for
Do not use this code for a different retinal disorder or for eye findings that are not documented as retrolental fibroplasia. Check documentation if the term is used loosely or historically.
Coding tip
Always verify laterality in the ophthalmology note before assigning H35.172.
