ICD-10 Code H30.109 – Unspecified Disseminated Chorioretinal Inflammation, Unspecified Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.109 – Unspecified disseminated chorioretinal inflammation, unspecified eye
What it is
This code identifies disseminated chorioretinal inflammation affecting the eye, but the record does not specify which eye. It is used when inflammation involves both the choroid and retina and the documentation remains nonspecific.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include decreased vision, floaters, eye discomfort, or visible chorioretinal lesions on ophthalmic examination.
When to use this code
Use H30.109 when the provider documents disseminated chorioretinal inflammation and does not identify the right or left eye. It also fits cases where the diagnosis is confirmed, but laterality is not stated in the note. If the chart names a specific eye, use the laterality-specific code instead.
Do not use for
Do not use this code for isolated choroiditis, retinitis, or other ocular inflammation without documented chorioretinal involvement. Check documentation if the condition is coded as a different type of posterior uveitis.
Coding tip
Confirm both the inflammatory pattern and laterality before coding; if either is missing, code only what the record clearly supports.
