Cysts of right upper eyelid

This code signifies the presence of an abnormal, sac-like growth containing fluid, air, or semi-solid material located on the right upper eyelid. These cysts can vary in size and may be asymptomatic or cause irritation, vision changes, or cosmetic concerns.

Apply this code when documentation clearly indicates a diagnosed cyst affecting the right upper eyelid. This includes various types of cysts such as epidermal inclusion cysts, dermoid cysts, or other benign cystic lesions. Supporting documentation should include physician notes detailing the location and nature of the cyst.

• Ensure the documentation specifies "right upper eyelid" to differentiate from other eyelid locations.
• Do not confuse with chalazion or hordeolum, which have distinct ICD-10-CM codes.
• If the cyst is congenital, consider additional codes from Chapter 17 (Congenital malformations, deformations and chromosomal abnormalities).
