Cyst of ora serrata, bilateral

This code signifies the presence of a cyst located at the ora serrata, the jagged anterior termination of the retina, affecting both eyes. These cysts are typically benign, fluid-filled sacs that can develop in this specific retinal region. They are often asymptomatic and discovered incidentally during a comprehensive ophthalmic examination.

Apply this code when documentation explicitly states the presence of an ora serrata cyst in both the right and left eyes. It is appropriate for incidental findings or when the cyst is noted during evaluation for other ocular conditions. Documentation should clearly specify the location and bilaterality of the cyst.

• Ensure documentation specifies "bilateral" involvement; otherwise, use the appropriate unilateral code (H33.111 or H33.112).
• Do not confuse with other retinal cysts, such as macular cysts (H35.31-) or retinoschisis (H35.30).
• If the cyst is a secondary finding to another underlying retinal condition, sequence the primary condition first, if applicable.
