ICD-10 Code H35.073 – Retinal Telangiectasis, Bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.073 – Retinal telangiectasis, bilateral
What it is
H35.073 identifies abnormal, dilated retinal blood vessels in both eyes. Use it when the record specifically documents bilateral retinal telangiectasis.
Clinical signs
Findings may include retinal vascular dilation, leakage, or associated retinal changes on eye examination or imaging. Clinical features vary; refer to documentation.
When to use this code
Use this code when the ophthalmology note clearly states retinal telangiectasis in both eyes. It is appropriate for documented bilateral retinal vascular ectasia, including cases identified on exam, fluorescein angiography, or retinal imaging. Check documentation if laterality is unclear.
Do not use for
Do not use it for unilateral retinal telangiectasis or for nonspecific retinal vascular abnormalities without a documented diagnosis. If the note only says “retinal changes” or “vascular leakage,” check documentation.
Coding tip
Confirm bilateral laterality in the provider record before assigning H35.073.
