ICD-10 Code H30.22 – Posterior cyclitis, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.22 – Posterior cyclitis, left eye
What it is
H30.22 identifies posterior cyclitis affecting the left eye. It is an inflammatory condition involving the ciliary body region behind the iris.
Clinical signs
Clinical features vary; refer to documentation. You may see signs of intraocular inflammation, such as ocular pain, blurred vision, photophobia, or inflammatory findings on eye examination.
When to use this code
Use H30.22 when the provider documents posterior cyclitis in the left eye. Code it when the diagnosis is confirmed or clearly supported in the record, including ophthalmology assessments.
If the note only states uveitis, iritis, or unspecified eye inflammation, check documentation before assigning this code. Laterality matters, so verify that the left eye is specifically identified.
Do not use for
Do not use this code for right eye, bilateral, or unspecified laterality. Do not assign it for other ocular inflammatory disorders unless posterior cyclitis is clearly documented.
Coding tip
Confirm both the exact diagnosis and laterality in the provider note before coding.
