About coding pancreas congenital deformity
The ICD-10-CM code for pancreas congenital deformity is Q45.3 (Other congenital malformations of pancreas and pancreatic duct). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Q45.3.
Within Q45, choose Q45.3 (Other congenital malformations of pancreas and pancreatic duct) 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 specified congenital malformations of digestive system (Q45.8) and congenital malformation of digestive system, unspecified (Q45.9).
Don't report Q45.3 together with the conditions in its Excludes1 note: congenital diabetes mellitus (E10.-), cystic fibrosis (E84.0-E84.9), fibrocystic disease of pancreas (E84.-) and neonatal diabetes mellitus (P70.2).
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.
