Q44.7Other congenital malformations of liver

Q44.7 is the ICD-10-CM diagnosis code for other congenital malformations of liver. It belongs to category Q44 (congenital malformations of gallbladder, bile ducts and liver), block Q38-Q45 (other congenital malformations of the digestive system) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within Q44, choose Q44.7 (Other congenital malformations of liver) only when documentation doesn't support a more specific option: agenesis, aplasia and hypoplasia of gallbladder (Q44.0), other congenital malformations of gallbladder (Q44.1), atresia of bile ducts (Q44.2), congenital stenosis and stricture of bile ducts (Q44.3), Choledochal cyst (Q44.4), other congenital malformations of bile ducts (Q44.5) and cystic disease of liver (Q44.6).

To report this condition, pick the subcode that matches the documentation: Q44.70 (unspecified), Q44.71 (syndrome) and Q44.79 (liver).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2024 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 751.60 (unspecified anomaly of gallbladder, bile ducts, and liver) and 751.69 (other anomalies of gallbladder, bile ducts, and liver).
