Exudative cyst of pars plana, right eye

This code describes a condition where fluid-filled sacs (cysts) develop in the pars plana region of the right eye, characterized by the leakage or accumulation of exudative material. The pars plana is a part of the ciliary body, located behind the iris and lens, and these cysts can potentially impact vision or ocular health.

Use this code when documentation specifically identifies an exudative cyst located in the pars plana of the patient's right eye. This diagnosis is typically made by an ophthalmologist through dilated fundus examination, ultrasound, or optical coherence tomography (OCT).

• Ensure the documentation specifies "exudative" to differentiate from other types of pars plana cysts.
• Verify the laterality is clearly documented as "right eye."
• Do not use this code for non-exudative or unspecified pars plana cysts; refer to other H21.3x codes.
