Cyst of ora serrata, left eye

This code describes a fluid-filled sac or lesion located at the ora serrata of the left eye. The ora serrata is the serrated junction between the retina and the ciliary body. These cysts are typically benign and often asymptomatic.

Use this code when documentation specifies a cyst of the ora serrata in the left eye. This diagnosis is typically made during a comprehensive ophthalmic examination, often through indirect ophthalmoscopy or optical coherence tomography (OCT). Supporting documentation should include the location and laterality of the cyst.

• Ensure laterality is clearly documented (left eye).
• Do not confuse with retinal detachment or other retinal cysts not specifically located at the ora serrata.
• If the cyst is bilateral, a separate code for the right eye (H33.111) and unspecified eye (H33.119) would be used in addition to this code.
