ICD-10 Code H35.352 – Cystoid macular degeneration, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.352 – Cystoid macular degeneration, left eye
What it is
H35.352 identifies cystoid macular degeneration in the left eye. It refers to cystic swelling or degeneration affecting the macula, the part of the retina needed for sharp central vision.
Clinical signs
Typical findings include blurred or distorted central vision, reduced reading vision, and macular cystic changes on eye examination or imaging. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents cystoid macular degeneration specifically in the left eye. It is appropriate when the record clearly identifies laterality and the diagnosis, such as in ophthalmology notes, retinal imaging reports, or follow-up assessments.
If the documentation only says macular edema or cystoid changes without stating degeneration, check documentation before assigning H35.352. Make sure the left eye is explicitly supported in the chart.
Do not use for
Do not use this code for right eye or bilateral disease, or when the record describes a different macular disorder. Do not assume laterality from exam findings alone.
Coding tip
Always verify both the diagnosis wording and laterality in the provider note before coding H35.352.
