Q35.9
ICD-10-CMThis code identifies a congenital malformation characterized by a persistent opening in the roof of the mouth, where the two sides of the palate fail to fuse completely during fetal development. This defect can involve the hard palate, soft palate, or both, and may lead to feeding difficulties, speech impediments, and recurrent ear infections.
Assign this code when medical record documentation clearly indicates the presence of a cleft palate but lacks specific details regarding the type (e.g., hard, soft, unilateral, bilateral, complete, incomplete). This code is appropriate for initial diagnoses when further diagnostic workup is pending or when the specific type of cleft palate is not documented.
