Cleft lip and cleft palate (Q35-Q37)

ICD-10 codes Q35 through Q37 specifically classify various types of cleft lip and cleft palate conditions. These codes distinguish between cleft palate alone, cleft lip alone, and combinations of cleft palate with cleft lip, helping healthcare professionals accurately document the precise anatomical involvement.

This range covers cleft palate codes (Q35), which include subtypes like cleft hard palate (Q35.1), cleft soft palate (Q35.3), cleft hard palate with soft palate involvement (Q35.5), and cleft uvula (Q35.7). The codes also address cleft lip conditions (Q36), differentiating bilateral (Q36.0), median (Q36.1), and unilateral cleft lips (Q36.9). Furthermore, the combined forms involving both palate and lip fall under Q37 codes, distinguishing bilateral or unilateral cleft lip paired with variations of cleft palate (hard, soft, or both). Common terms such as "complete cleft lip," "bilateral cleft lip," "submucous cleft palate," and "cleft palate with cleft lip" relate directly to these codes, supporting clear medical documentation and billing. This specificity ensures precise coding for surgical planning and outcomes tracking in craniofacial congenital anomalies.

Instructional Notations

Use Additional Code

The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
