Cyst of ora serrata, unspecified eye

This code describes a cyst located at the ora serrata, which is the jagged anterior termination of the retina. These cysts are typically benign and often discovered incidentally during ophthalmoscopic examination. They are usually asymptomatic and do not significantly impair vision.

Use this code when documentation specifies a cyst of the ora serrata without further detail regarding the specific eye affected. This diagnosis is typically made by an ophthalmologist based on direct visualization during a dilated fundus exam. Documentation should clearly state "cyst of ora serrata" and indicate that the laterality is unspecified.

• Ensure documentation specifies "ora serrata" to differentiate from other retinal or ciliary body cysts.
• Avoid using this code if the laterality (right or left eye) is clearly documented; instead, use the more specific codes for right (H33.111) or left (H33.112) eye.
• This code is for the diagnosis itself; do not confuse it with codes for procedures performed to treat or evaluate the cyst.
