ICD-10 Code H30.003 – Unspecified focal chorioretinal inflammation, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.003 – Unspecified focal chorioretinal inflammation, bilateral
What it is
This code identifies focal inflammation involving the choroid and retina in both eyes, when the specific cause or subtype is not documented. Use it for bilateral chorioretinal inflammation described as unspecified.
Clinical signs
Findings may include reduced vision, blurred vision, floaters, or retinal inflammatory lesions on eye examination. Clinical features vary; refer to documentation.
When to use this code
Use H30.003 when the provider documents focal chorioretinal inflammation affecting both eyes and does not name a more specific diagnosis. It also fits when the record confirms bilateral involvement but leaves the etiology, location details, or subtype unspecified. Check documentation if laterality or specificity is unclear.
Do not use for
Do not use this code for unilateral disease, generalized chorioretinal inflammation, or conditions with a more specific documented diagnosis. Check documentation.
Coding tip
Verify both laterality and the word “unspecified” in the note before assigning H30.003.
