ICD-10 Code H30.9 – Unspecified chorioretinal inflammation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.9 – Unspecified chorioretinal inflammation
What it is
H30.9 identifies inflammation involving the choroid and retina when the record does not specify a more exact type. Use it for chorioretinal inflammatory disease that is documented, but not further characterized.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include visual disturbance, ocular inflammation, or retinal/choroidal changes noted on examination or imaging.
When to use this code
Use H30.9 when the provider documents chorioretinal inflammation without naming a specific subtype, location, or cause. It also fits cases where the note confirms the diagnosis but leaves the condition unspecified.
If later documentation identifies a more precise chorioretinal disorder, code the specific diagnosis instead. Check documentation for laterality, acuity, and whether the inflammation is infectious or noninfectious.
Do not use for
Do not use this code for isolated choroiditis, retinitis, or other eye disorders that are documented separately. Avoid it when the record provides a more specific chorioretinal diagnosis.
Coding tip
Query the provider when the chart says “chorioretinitis” or “retinochoroiditis” but does not clarify the exact type or laterality.
