ICD-10 code for duodenum atresia

The ICD-10-CM code for duodenum atresia is Q41.0 (Congenital absence, atresia and stenosis of duodenum).

Within Q41 (congenital absence, atresia and stenosis of small intestine), Q41.0 is specifically for congenital absence, atresia and stenosis of duodenum. Related codes cover jejunum (Q41.1), ileum (Q41.2), other specified parts of small intestine (Q41.8) and part unspecified (Q41.9).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 393 (Other Digestive System Diagnoses with MCC, relative weight 1.5881), DRG 394 (Other Digestive System Diagnoses with CC, relative weight 0.9228) and DRG 395 (Other Digestive System Diagnoses without CC/MCC, relative weight 0.6382), in MDC 06 (Diseases and Disorders of the Digestive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
