ICD-10 Code H30.021 – Focal chorioretinal inflammation of posterior pole, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.021 – Focal chorioretinal inflammation of posterior pole, right eye
What it is
This code identifies localized inflammation involving the choroid and retina at the posterior pole of the right eye. Use it when documentation specifies a focal chorioretinal inflammatory process in that exact eye location.
Clinical signs
Findings may include decreased vision, blurred central vision, or a visible inflammatory lesion near the macula or posterior pole. Clinical features vary; refer to documentation.
When to use this code
Use H30.021 when the provider documents focal chorioretinal inflammation limited to the posterior pole of the right eye. It is appropriate for ophthalmology notes, imaging reports, or assessment statements that clearly identify the site and laterality. If the record only says chorioretinitis without location, check documentation.
Do not use for
Do not use this code for left-eye or bilateral disease, or for nonspecific posterior uveitis without chorioretinal involvement. Check documentation if the diagnosis is broader or the eye laterality is unclear.
Coding tip
Always confirm both laterality and the posterior pole location before assigning H30.021.
