Other congenital malformations of the digestive system (Q38-Q45)

ICD-10 codes Q38 to Q45 cover various congenital malformations of the digestive system, including defects involving the tongue, mouth, pharynx, esophagus, stomach, intestines, gallbladder, bile ducts, liver, and pancreas. These codes are used to classify congenital anomalies such as tongue abnormalities, esophageal atresia, congenital hypertrophic pyloric stenosis, intestinal atresia and stenosis, and biliary atresia.

This code range provides detailed categories for birth defects affecting the upper and lower digestive tract. For example, Q38 codes address malformations like ankyloglossia (tongue tie) and congenital lip pits, while Q39 codes specify atresia and fistulas of the esophagus. Q40 includes pyloric stenosis and hiatus hernia. Moving lower, Q41 and Q42 are used for congenital absence, atresia, or stenosis of the small and large intestines and anus, with synonyms such as “congenital duodenal obstruction” or “anal atresia.” Hirschsprung's disease and Meckel’s diverticulum fall under Q43. Congenital issues of the liver, gallbladder, and bile ducts, including biliary atresia and choledochal cysts, are coded in Q44. The Q45 codes cover pancreatic malformations like annular pancreas and pancreatic cysts. These codes help medical coders precisely document complex congenital digestive abnormalities, facilitating proper diagnosis and treatment planning.
