Exudative cyst of pars plana, bilateral

This code signifies the presence of a fluid-filled sac, or cyst, located on the pars plana of both eyes. The pars plana is a flat, anterior region of the ciliary body, and the "exudative" nature indicates that the cyst is formed by the leakage of fluid. This condition can potentially affect vision due to its proximity to the retina and lens.

This code is appropriate when documentation clearly indicates an exudative cyst affecting the pars plana in both the right and left eyes. The diagnosis should be confirmed by an ophthalmologist, often through imaging techniques such as ultrasound or optical coherence tomography (OCT).

• Ensure documentation specifies "bilateral" involvement; otherwise, a laterality-specific code may be more appropriate.
• Distinguish from other types of pars plana cysts (e.g., non-exudative) as different codes exist.
• Always review the operative report or clinical notes for precise location and characteristics of the cyst.
