Macrocheilia

This code represents macrocheilia, a congenital or acquired condition characterized by abnormally enlarged lips. This enlargement can affect one or both lips and may be due to various underlying causes such as lymphatic malformations, hemangiomas, or inflammatory processes.

Assign this code when documentation clearly indicates a diagnosis of macrocheilia. This applies to cases where the primary concern is the enlarged lip(s), whether it's an isolated finding or part of a broader syndrome. Supporting documentation should include physical exam findings noting lip size and any associated symptoms.

• Do not confuse with angioedema, which is typically transient and allergic in nature; macrocheilia implies a more persistent enlargement.
• If the macrocheilia is secondary to another condition (e.g., lymphangioma), code the underlying condition first, followed by this code.
• Ensure the medical record specifies which lip(s) are affected if relevant for clinical understanding, though this code does not differentiate laterality.
