About the Q35 Code Range
The ICD-10 code section Q35 covers various forms of cleft palate, a congenital condition where the roof of the mouth does not fully close during fetal development. These codes specify different types and locations of cleft palate defects, aiding precise diagnosis and treatment planning.
This section includes subcodes such as Q35.1 for cleft hard palate (including terms like "cleft of right hard palate" or "complete cleft of hard palate"), Q35.3 for cleft soft palate (e.g., "bilateral cleft of soft palate"), and Q35.5 covering combined clefts of both hard and soft palate with multiple synonyms like "complete bilateral cleft palate" and "submucous cleft palate." Also included is Q35.7 for cleft uvula, known as "congenital anomaly of uvula." The code Q35.9 captures unspecified cleft palate and encompasses a wide range of associated congenital anomalies and syndromes. Understanding these synonyms alongside their ICD-10 codes helps medical coders accurately match clinical documentation to billing codes when the patient presents with conditions such as cleft hard palate, soft palate, or uvula abnormalities.
