ICD-10 Code H30.02 – Focal chorioretinal inflammation of posterior pole (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.02 – Focal chorioretinal inflammation of posterior pole
What it is
This code identifies a localized inflammatory disorder affecting the choroid and retina at the posterior pole of the eye. It indicates a specific site-based diagnosis rather than a generalized eye inflammation.
Clinical signs
Findings may include decreased central vision, visual distortion, or a visible focal chorioretinal lesion near the macula or posterior pole. Clinical features vary; refer to documentation.
When to use this code
Use H30.02 when the provider documents focal chorioretinal inflammation limited to the posterior pole. You should select it when the record clearly identifies the anatomic location and inflammatory nature of the condition. Check documentation if the note is nonspecific or describes another retinal disorder.
Do not use for
Do not use this code for diffuse chorioretinal inflammation, lesions outside the posterior pole, or noninflammatory chorioretinal scars. If the diagnosis is uncertain, check documentation.
Coding tip
Verify both the inflammatory diagnosis and the posterior pole location before assigning H30.02.
