ICD-10 Code H30 – Chorioretinal inflammation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30 – Chorioretinal inflammation
What it is
H30 identifies inflammation involving the choroid and retina, the layers at the back of the eye. Use it when the record documents chorioretinal inflammation without a more specific subtype.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the chart may note blurred vision, floaters, reduced visual acuity, or ocular inflammation seen on examination.
When to use this code
Use H30 when the provider diagnoses chorioretinal inflammation and does not specify a more detailed category. It may also fit when the note describes inflammatory involvement of both the choroid and retina, but the exact cause or laterality is not documented. Check documentation if another eye disorder is named.
Do not use for
Do not use this code for isolated choroid disease, isolated retinal disease, or noninflammatory eye conditions. If the record identifies a more specific chorioretinal disorder, code that diagnosis instead.
Coding tip
Look for the provider’s exact wording and any documented laterality or specificity before assigning H30.
