Microcheilia

This code represents microcheilia, a congenital anomaly characterized by abnormally small or underdeveloped lips. This condition can affect either the upper lip, lower lip, or both, and may be an isolated finding or part of a broader syndrome. It can impact facial aesthetics and, in severe cases, oral function.

Use this code when documentation explicitly states a diagnosis of microcheilia. This typically occurs in pediatric patients or individuals presenting with congenital facial anomalies. Supporting documentation should include physician notes detailing the small size of the lips, often observed during physical examination.

• Differentiate from hypoplasia of the lip due to trauma or disease; this code is specifically for congenital microcheilia.
• If microcheilia is part of a recognized syndrome (e.g., Van der Woude syndrome), code the syndrome first, followed by this code for the specific lip anomaly.
• Ensure the documentation clearly distinguishes between microcheilia and other lip abnormalities like cleft lip (Q36.-) or macrocheilia (Q18.6).
