Posterior cyclitis, bilateral

This code signifies inflammation of the ciliary body and choroid, specifically affecting the posterior segment of both eyes. It indicates a bilateral inflammatory process involving the uveal tract behind the iris.

Apply this code when documentation clearly states "posterior cyclitis" or "pars planitis" affecting both eyes. Support for this code includes ophthalmologist notes detailing bilateral inflammation of the posterior uvea, often with associated vitreous opacities or macular edema.

• Differentiate from anterior cyclitis (H30.0-) or panuveitis (H30.8-) based on the documented location of inflammation.
• Ensure the documentation explicitly states "bilateral" involvement; otherwise, use the appropriate unilateral code.
• Consider sequencing this code after any underlying systemic conditions causing the cyclitis, such as autoimmune diseases.
