Chalazion left lower eyelid

This code signifies an inflammatory lesion of the meibomian gland, specifically located on the lower eyelid of the left eye. It presents as a painless, firm nodule resulting from obstruction of the gland's duct and subsequent lipid extravasation into the surrounding tissue.

Apply this code when documentation clearly indicates a chalazion affecting the left lower eyelid. This diagnosis is typically made based on clinical examination findings of a localized, non-tender swelling.

• Ensure laterality (left) and eyelid location (lower) are explicitly documented to support this specific code.
• Differentiate from hordeolum (stye), which is an acute, painful infection, not a chronic inflammatory lesion.
• Do not use for unspecified chalazion or chalazion of other specified sites; use more specific codes when available.
