ICD-10 Code H30.133 – Disseminated chorioretinal inflammation, generalized, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.133 – Disseminated chorioretinal inflammation, generalized, bilateral
What it is
This code identifies a bilateral inflammatory condition affecting the choroid and retina in a generalized, disseminated pattern. Use it when documentation states both eyes are involved and the inflammation is widespread rather than localized.
Clinical signs
Findings may include multifocal chorioretinal lesions, blurred vision, floaters, or reduced visual acuity. Clinical features vary; refer to documentation and ophthalmic examination findings.
When to use this code
Use H30.133 when the provider documents disseminated chorioretinal inflammation involving both eyes, with generalized distribution. It is appropriate for confirmed bilateral disease in the choroid and retina. If the note only says chorioretinitis, posterior uveitis, or unspecified eye involvement, check documentation before assigning this code.
Do not use for
Do not use this code for unilateral disease, localized lesions, or anterior uveitis. Do not assume bilateral involvement unless the record clearly states it.
Coding tip
Verify both laterality and the generalized/disseminated wording in the ophthalmology note before coding.
