ICD-10 Code H35.46 – Secondary vitreoretinal degeneration (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.46 – Secondary vitreoretinal degeneration
What it is
H35.46 identifies secondary vitreoretinal degeneration, meaning degenerative change involving the retina and vitreous that occurs as a result of another eye condition or injury. Use it when documentation specifically states this secondary process.
Clinical signs
Clinical features vary; refer to documentation. Findings may include retinal or vitreous degeneration noted on ophthalmic exam, but you should rely on the provider’s documented diagnosis rather than infer signs from nonspecific visual complaints.
When to use this code
Use H35.46 when the ophthalmologist documents secondary vitreoretinal degeneration as the confirmed diagnosis. It is appropriate when the condition is described as a degenerative change secondary to another ocular disorder, trauma, or prior eye pathology. Code the underlying cause as directed by the record.
Do not use for
Do not use this code for primary retinal or vitreous degeneration, or for vague abnormal eye findings without a documented diagnosis. Check documentation if the note only mentions retinal changes, vitreous opacities, or unspecified visual disturbance.
Coding tip
Assign H35.46 only when the record clearly states “secondary vitreoretinal degeneration,” and report the underlying eye condition separately when documented.
