ICD-10 Code H35.079 – Retinal Telangiectasis, Unspecified Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.079 – Retinal telangiectasis, unspecified eye
What it is
This code identifies abnormal, dilated retinal blood vessels in an unspecified eye. Use it when the record documents retinal telangiectasis but does not specify right or left eye.
Clinical signs
Clinical features vary; refer to documentation. Findings may include visible retinal vascular dilation or leakage on eye examination or imaging, with associated macular changes when noted.
When to use this code
Use H35.079 when the provider documents retinal telangiectasis and laterality is not stated. It also fits when the chart confirms the diagnosis but does not identify a specific eye. If laterality is documented elsewhere, code that detail instead.
Do not use for
Do not use this code for other retinal vascular disorders without documented telangiectasis. Check documentation if the condition is described as a different retinal disease or if the eye laterality is known.
Coding tip
Verify laterality in the ophthalmology note before assigning the unspecified-eye code.
