Cleft hard palate with unilateral cleft lip

This code identifies a congenital malformation characterized by a split or opening in the hard palate, the bony front part of the roof of the mouth, occurring simultaneously with a cleft on one side of the upper lip. This condition results from incomplete fusion of facial structures during fetal development.

Assign this code for patients diagnosed with a cleft involving both the hard palate and a unilateral cleft lip. Documentation should clearly specify the involvement of the hard palate and confirm the unilateral nature of the lip cleft. This code is typically used for initial diagnosis and subsequent encounters related to the management of this specific congenital anomaly.

• Differentiate from Q37.0 (cleft hard palate with bilateral cleft lip) and Q37.2 (cleft soft palate with unilateral cleft lip).
• Ensure documentation specifies "hard palate" versus "soft palate" and "unilateral" versus "bilateral" for the lip cleft.
• Consider additional codes for associated anomalies or complications, such as feeding difficulties or speech impediments.
