ICD-10 Code H35.35 – Cystoid Macular Degeneration (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.35 – Cystoid macular degeneration
What it is
Cystoid macular degeneration refers to cyst-like changes in the macula, the central retina responsible for sharp vision. It is a retinal diagnosis that can affect central visual function.
Clinical signs
Findings may include blurred or distorted central vision, reduced visual acuity, or macular cystic changes on eye examination or imaging. Clinical features vary; refer to documentation.
When to use this code
Use H35.35 when the provider documents cystoid macular degeneration as the diagnosed retinal condition. It may apply when the record describes macular cystic degeneration without a more specific coded diagnosis. If the note names another retinal disorder, code that condition instead.
Do not use for
Do not use this code for nonspecific vision complaints without a documented retinal diagnosis. Do not assign it when the chart identifies a different macular disease or postoperative cystoid macular edema; check documentation.
Coding tip
Code from the provider’s exact wording and confirm whether the condition is degeneration, edema, or another macular disorder.
