2026 ICD-10-CM Diagnosis Code H30.121 – Disseminated chorioretinal inflammation, peripheral right eye
What it is
This code identifies disseminated chorioretinal inflammation affecting the peripheral part of the right eye. It refers to inflammation involving the choroid and retina in a widespread pattern, localized to the right eye.
Clinical signs
Findings may include inflammatory lesions in the peripheral retina and choroid, with visual symptoms varying by severity and location. Clinical features vary; refer to documentation.
When to use this code
Use H30.121 when the provider documents disseminated chorioretinal inflammation in the peripheral right eye. Choose this code when the laterality and peripheral location are clearly stated in the record. If the note only says chorioretinal inflammation without these details, check documentation.
Do not use for
Do not use this code for inflammation in the left eye, bilateral disease, or unspecified eye. Also avoid it when the record describes a different retinal or choroidal disorder.
Coding tip
Verify both laterality and the peripheral location before assigning H30.121.
