Posterior cyclitis, left eye

This code signifies inflammation of the ciliary body and choroid, specifically located in the posterior segment of the left eye. It indicates a form of uveitis affecting the back part of the eye, distinct from anterior or panuveitis.

Apply this code when documentation clearly states "posterior cyclitis" or "posterior uveitis" affecting the left eye. Supporting documentation should include ophthalmologist notes detailing the location of inflammation within the posterior segment, such as the ciliary body and choroid.

• Ensure laterality is explicitly documented as "left eye" to avoid unspecified coding.
• Distinguish from H30.0 (serous choroidopathy) and H30.1 (disseminated choroiditis) which have different inflammatory patterns.
• Look for associated systemic conditions, as posterior cyclitis can be a manifestation of autoimmune diseases, and code those conditions first if they are the underlying cause.
