ICD-10 Code H30.2 – Posterior cyclitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.2 – Posterior cyclitis
What it is
H30.2 identifies posterior cyclitis, an inflammatory condition affecting the posterior portion of the ciliary body. Use it when the record specifically documents this diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Findings may include ocular inflammation signs noted on examination, but you should code only when the provider clearly identifies posterior cyclitis.
When to use this code
Use H30.2 when the clinician documents posterior cyclitis as the diagnosis, such as in ophthalmology or uveitis evaluations. It is appropriate for encounters focused on this specific inflammatory condition. If the note only says “uveitis” or “iritis,” check documentation before assigning this code.
Do not use for
Do not use H30.2 for nonspecific eye inflammation, anterior cyclitis, or other uveitis types unless posterior cyclitis is documented. Check documentation if the anatomic site is unclear.
Coding tip
Confirm the exact uveal location in the assessment; the diagnosis must support posterior cyclitis, not a broader inflammatory eye disorder.
