Chalazion right lower eyelid

This code signifies a chalazion, which is a chronic, sterile, lipogranulomatous inflammation of a meibomian gland, specifically located on the right lower eyelid. It presents as a painless, firm nodule resulting from obstruction of the gland's duct.

Use this code when documentation clearly indicates a chalazion affecting the right lower eyelid. This diagnosis is typically made based on clinical examination, noting the characteristic firm, non-tender lump. It is appropriate for both initial diagnosis and follow-up visits for this specific condition.

• Ensure laterality (right) and eyelid location (lower) are explicitly documented.
• Differentiate from a hordeolum (stye), which is an acute, painful infection of an eyelid gland.
• Consider additional codes for any associated complications, such as secondary infection, if present.
