ICD-10 Code H30.122 – Disseminated chorioretinal inflammation, peripheral, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.122 – Disseminated chorioretinal inflammation, peripheral, left eye
What it is
This code identifies inflammation involving the choroid and retina in the peripheral part of the left eye. Use it when documentation specifies disseminated chorioretinal inflammation and the left eye location.
Clinical signs
Findings may include ocular inflammation, blurred vision, floaters, or peripheral retinal lesions. Clinical features vary; refer to documentation and the ophthalmology assessment.
When to use this code
Use H30.122 when the provider documents disseminated chorioretinal inflammation limited to the peripheral left eye. It is appropriate for confirmed diagnoses in the left eye, even if the note also describes active inflammation or follow-up care. If the record does not clearly identify the eye or the peripheral location, check documentation.
Do not use for
Do not use this code for unspecified chorioretinal inflammation, right eye disease, or bilateral involvement. Do not assign it when the chart only mentions retinal inflammation without choroidal involvement.
Coding tip
Verify laterality and the peripheral location in the ophthalmology note before assigning H30.122.
