ICD-10 Code H35.353 – Cystoid Macular Degeneration, Bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.353 – Cystoid macular degeneration, bilateral
What it is
This code identifies cystoid macular degeneration affecting both eyes. It refers to cystic changes in the macula, the central retina responsible for sharp, detailed vision.
Clinical signs
Patients may have blurred central vision, reduced reading ability, or distortion of straight lines. Clinical features vary; refer to documentation and ophthalmic examination findings.
When to use this code
Use H35.353 when the provider documents bilateral cystoid macular degeneration as the diagnosed condition. It is appropriate when both eyes are involved and the record supports a macular degenerative process rather than a transient edema episode. Check documentation if the note uses nonspecific retinal or macular terminology.
Do not use for
Do not use this code for unilateral disease or for nonspecific macular edema without documented degeneration. If the chart describes a different retinal disorder, choose the more specific diagnosis.
Coding tip
Confirm bilateral involvement in the assessment or impression before assigning H35.353.
