About coding digestive organs duplication
The ICD-10-CM code for digestive organs duplication is Q45.8 (Other specified congenital malformations of digestive system).
Within Q45, choose Q45.8 (Other specified congenital malformations of digestive system) only when documentation doesn't support a more specific option: agenesis, aplasia and hypoplasia of pancreas (Q45.0), Annular pancreas (Q45.1), congenital pancreatic cyst (Q45.2), other congenital malformations of pancreas and pancreatic duct (Q45.3) and congenital malformation of digestive system, unspecified (Q45.9).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
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.
