Posterior cyclitis, unspecified eye

This code signifies inflammation of the ciliary body and choroid, specifically affecting the posterior segment of the eye, without further specification of the affected eye. It represents a form of uveitis where the inflammation is located behind the iris and ciliary body.

Use this code when documentation indicates posterior cyclitis but does not specify laterality (right, left, or bilateral). This diagnosis is typically supported by ophthalmological examination findings such as vitreous cells, retinal vasculitis, or choroidal infiltrates.

• Avoid using this code if the medical record specifies the affected eye; instead, use the more specific H30.21 (right eye), H30.22 (left eye), or H30.23 (bilateral).
• Ensure documentation clearly states "posterior cyclitis" or "posterior uveitis" with involvement of the ciliary body and choroid, and lacks laterality.
• Consider co-reporting with codes for underlying systemic conditions if the posterior cyclitis is secondary to another disease process.
