ICD-10 Code H30.91 – Unspecified chorioretinal inflammation, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.91 – Unspecified chorioretinal inflammation, right eye
What it is
This code identifies inflammation involving the choroid and retina in the right eye when the exact type is not specified. Use it for a documented right-eye chorioretinal inflammatory disorder without a more precise diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings may include decreased vision, floaters, blurred vision, or funduscopic inflammation affecting the choroid and retina.
When to use this code
Use H30.91 when the provider documents unspecified chorioretinal inflammation limited to the right eye. It is appropriate when the record confirms inflammation but does not name a more specific subtype, cause, or laterality beyond the right eye.
Do not use for
Do not use this code if the record identifies a more specific chorioretinal diagnosis or if the inflammation is not in the right eye. Check documentation when the note only says “retinitis,” “choroiditis,” or another broader term.
Coding tip
Verify both laterality and specificity; if the provider names a more exact disorder, code that instead of H30.91.
