ICD-10 Code H32 – Chorioretinal disorders in diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H32 – Chorioretinal disorders in diseases classified elsewhere
What it is
H32 identifies chorioretinal disorders that occur as a manifestation of another disease. Use it when the eye condition is linked to an underlying systemic or infectious process, not when the chorioretinal disease is coded on its own.
Clinical signs
Clinical features vary; refer to documentation. Findings may include chorioretinal inflammation or scarring noted on eye examination, with the underlying disease documented as the cause.
When to use this code
Use H32 when the provider documents a chorioretinal disorder “in diseases classified elsewhere” and identifies the causal condition. This code is appropriate only when the record clearly ties the eye disorder to another disease. Add the underlying diagnosis first when required by coding rules.
Do not use for
Do not use H32 for primary chorioretinal disorders without an underlying cause. Check documentation if the record only states retinal or choroidal disease, because a different code may apply.
Coding tip
Verify the linked systemic or infectious diagnosis and sequence codes according to the provider’s documentation and official ICD-10-CM instructions.
