Chalazion right upper eyelid

This code identifies an inflamed, benign cyst located on the right upper eyelid, resulting from an obstructed meibomian gland. It typically presents as a firm, painless nodule, though it can become tender if acutely inflamed.

Assign this code when documentation clearly indicates a chalazion affecting the right upper eyelid. Supporting documentation should specify the laterality (right) and location (upper eyelid) of the chalazion.

• Differentiate from a hordeolum (stye), which is an acute bacterial infection of an eyelash follicle or meibomian gland.
• Ensure the documentation specifies "upper" eyelid; if only "right eyelid" is noted, query for clarification.
• Consider additional codes for any associated symptoms or complications, such as pain or vision disturbance.
