ICD-10 Code H30.0 – Focal chorioretinal inflammation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.0 – Focal chorioretinal inflammation
What it is
Use this code for a localized inflammatory process involving the choroid and retina. It describes a focal lesion rather than diffuse eye inflammation.
Clinical signs
Clinical features vary; refer to documentation. Typical records may note a focal chorioretinal lesion, decreased vision, floaters, or retinal inflammation on exam or imaging.
When to use this code
Assign H30.0 when the provider documents focal chorioretinal inflammation, chorioretinitis, or a similar localized inflammatory diagnosis affecting the choroid and retina. Use the code when the record clearly identifies the condition and does not specify a more precise subtype. Check documentation if the eye finding is only suspected.
Do not use for
Do not use this code for nonspecific eye pain, conjunctivitis, or inflammation limited to other ocular structures. If the documentation names a different retinal, choroidal, or infectious process, code that condition instead.
Coding tip
Code from the provider’s exact wording and confirm laterality or etiology only when documented.
