ICD-10 code for pancreas congenital annular

The ICD-10-CM code for pancreas congenital annular is Q45.1 (Annular pancreas).

Within Q45 (other congenital malformations of digestive system), Q45.1 is specifically for Annular pancreas. Related codes cover agenesis, aplasia and hypoplasia of pancreas (Q45.0), congenital pancreatic cyst (Q45.2), other congenital malformations of pancreas and pancreatic duct (Q45.3), other specified congenital malformations of digestive system (Q45.8) and congenital malformation of digestive system, unspecified (Q45.9).

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 438 (Disorders of Pancreas Except Malignancy with MCC, relative weight 1.5765), DRG 439 (Disorders of Pancreas Except Malignancy with CC, relative weight 0.8402) and DRG 440 (Disorders of Pancreas Except Malignancy without CC/MCC, relative weight 0.5965), in MDC 07 (Diseases and Disorders of the Hepatobiliary System and Pancreas), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
