ICD-10 Code H30.033 – Focal chorioretinal inflammation, peripheral, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.033 – Focal chorioretinal inflammation, peripheral, bilateral
What it is
This code identifies localized inflammation involving the choroid and retina in the peripheral areas of both eyes. Use it when documentation specifies focal chorioretinal inflammation affecting both eyes.
Clinical signs
Findings may include peripheral retinal or chorioretinal inflammatory lesions, with symptoms such as blurred vision or floaters. Clinical features vary; refer to documentation.
When to use this code
Use H30.033 when the provider documents focal chorioretinal inflammation in the peripheral retina of both eyes. It fits bilateral disease with a clearly stated chorioretinal inflammatory process, not a nonspecific retinal disorder. Check documentation if laterality or location is unclear.
Do not use for
Do not use this code for unilateral disease, diffuse chorioretinal inflammation, or conditions limited to the retina without choroidal involvement. Do not assign it when the record only says “retinitis” or “chorioretinitis” without bilateral peripheral detail.
Coding tip
Confirm both laterality and the peripheral, focal wording in the note before assigning H30.033.
