ICD-10 Code H30.23 – Posterior cyclitis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H30.23 – Posterior cyclitis, bilateral
What it is
H30.23 identifies inflammation involving the posterior part of the ciliary body in both eyes. Use it when the documentation specifically states posterior cyclitis and notes bilateral involvement.
Clinical signs
Clinical features vary; refer to documentation. Records may describe bilateral ocular inflammation, eye pain, redness, blurred vision, or posterior segment findings consistent with cyclitis.
When to use this code
Use this code when the provider documents posterior cyclitis affecting both eyes, whether the diagnosis is made clinically or by ophthalmic examination. It is appropriate for active encounters, follow-up visits, or specialist assessments when bilateral disease is confirmed.
If laterality is documented as bilateral, do not default to an unspecified eye code. Check documentation if the note mentions related uveitis, iritis, or another inflammatory eye disorder without naming posterior cyclitis.
Do not use for
Do not use H30.23 for unilateral posterior cyclitis or for eye inflammation that is not specifically documented as posterior cyclitis. Check documentation when the condition is described only as uveitis or cyclitis without posterior and bilateral detail.
Coding tip
Code only when the chart clearly supports posterior cyclitis in both eyes; laterality matters.
