ICD-10 Code H35.363 – Drusen (degenerative) of macula, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.363 – Drusen (degenerative) of macula, bilateral
What it is
H35.363 identifies drusen deposits in both maculae, usually associated with age-related retinal change. These yellow-white extracellular deposits can affect central vision over time.
Clinical signs
Clinical features vary; refer to documentation. Common findings include macular drusen on fundus exam, with or without mild visual distortion or reduced central acuity.
When to use this code
Use this code when the provider documents bilateral degenerative macular drusen, including age-related macular change affecting both eyes. It fits confirmed retinal examination findings, even if symptoms are minimal. Do not assume laterality from a unilateral note.
Do not use for
Do not use H35.363 for drusen limited to one eye, unspecified macular degeneration, or non-macular retinal deposits. Check documentation if the record does not clearly state bilateral involvement.
Coding tip
Verify that the note explicitly supports bilateral macular drusen before assigning H35.363.
