ICD-10 Code H30.899 – Other chorioretinal inflammations, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.899 – Other chorioretinal inflammations, unspecified eye
What it is
This code identifies chorioretinal inflammation affecting the eye when the record does not specify the exact eye or a more precise chorioretinal diagnosis. It is used for inflammatory conditions involving the choroid and retina.
Clinical signs
Findings may include decreased vision, floaters, photophobia, or ocular inflammation on examination. Clinical features vary; refer to documentation for the specific anatomic site and cause.
When to use this code
Use H30.899 when the provider documents other chorioretinal inflammation and does not name a more specific type. It also fits cases where the eye is not identified as right, left, or bilateral in the note. If the record supports a more specific chorioretinal disorder, code that instead.
Do not use for
Do not use this code for anterior uveitis, isolated retinitis, or disorders with a more specific chorioretinal ICD-10 code. Check documentation if the laterality or exact inflammatory diagnosis is stated elsewhere.
Coding tip
Query the provider when the note says chorioretinal inflammation but lacks laterality or specificity.
