About the Q41 Code Range
ICD-10 code Q41 covers congenital conditions involving the absence, atresia, or stenosis of the small intestine. These codes are used to document and classify birth defects where parts of the small intestine, such as the duodenum, jejunum, or ileum, are missing or abnormally narrowed, causing digestive blockages or malformations.
The section includes specific codes like Q41.0 for duodenal atresia or stenosis, commonly called congenital duodenal obstruction, which can include related terms like partial obstruction of small bowel or duodenal stenosis. Q41.1 and Q41.2 relate to similar congenital narrowings or absence in the jejunum and ileum, respectively, with synonyms such as atresia of jejunum type IIIb or congenital ileal stenosis. Q41.8 and Q41.9 cover other specified or unspecified parts of the small intestine affected by these anomalies. Understanding these codes helps medical coders accurately capture documented congenital small intestinal disorders, essential for clinical records and treatment planning.
