About the Q35 Code Range
A cleft palate is a split in the hard or soft part of the roof of the mouth, present from birth because the palate did not join properly.
Within Q35, the subdivisions distinguish the hard palate (Q35.1), soft palate (Q35.3), or both (Q35.5). Separate subdivisions identify a cleft uvula (Q35.7) and an unspecified cleft palate (Q35.9).
