2025 ICD-10-CM code Q44.5
This code describes other congenital malformations of the bile ducts, including accessory hepatic duct, biliary duct duplication, and cystic duct duplication.
Medical necessity is established by the presence of a congenital malformation of the bile ducts impacting the patient's health. Further intervention (surgical or medical) might be medically necessary.
Diagnosis and management of this condition typically falls under pediatric gastroenterologists or pediatric surgeons.
In simple words: This code indicates a birth defect affecting the bile ducts, which carry digestive fluids from the liver and gallbladder to the intestines.
Other congenital malformations of bile ducts, including conditions such as accessory hepatic duct, biliary duct duplication, congenital malformation of bile duct NOS, and cystic duct duplication. This code excludes inborn errors of metabolism (E70-E88) and is not used on maternal records.
Example 1: A newborn infant is diagnosed with biliary atresia and further imaging reveals duplication of the common bile duct, which is coded as Q44.5., During a laparoscopic cholecystectomy, an incidental finding of an accessory hepatic duct is documented and reported with Q44.5., A child undergoing evaluation for recurrent abdominal pain is found to have a congenital cystic dilatation of the cystic duct, classified under Q44.5.
Documentation should include imaging reports (ultrasound, CT, MRI/MRCP, ERCP), operative reports if surgery is performed, and clinical findings related to the malformation.
** For diagnostic confidence in outpatient settings, append A (excluded), G (confirmed), V (tentative), or Z (condition after confirmed diagnosis).
