About Q45.3

Q45.3 is the ICD-10-CM diagnosis code for other congenital malformations of pancreas and pancreatic duct. It belongs to category Q45 (other congenital malformations of digestive system), block Q38-Q45 (other congenital malformations of the digestive system) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

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.

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.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 751.7 (anomalies of pancreas).
