ICD-10 Code H35.463 – Secondary vitreoretinal degeneration, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.463 – Secondary vitreoretinal degeneration, bilateral
What it is
H35.463 identifies secondary degeneration affecting the vitreous and retina in both eyes. Use it when the record shows bilateral vitreoretinal degeneration that is secondary to another eye process or condition.
Clinical signs
Findings may include retinal and vitreous degenerative changes documented on eye examination, imaging, or specialist assessment. Clinical features vary; refer to documentation.
When to use this code
Use this code when the ophthalmology note clearly states secondary vitreoretinal degeneration in both eyes. It fits bilateral documentation even if the underlying cause is described elsewhere in the chart. If the record only mentions degeneration without laterality or secondary status, check documentation.
Do not use for
Do not use H35.463 for primary retinal degeneration, unilateral disease, or nonspecific vitreous changes alone. Check documentation if the note does not support both bilateral and secondary involvement.
Coding tip
Confirm both laterality and the word “secondary” before assigning H35.463.
