Agenesis, aplasia and hypoplasia of gallbladder

This code signifies a congenital absence, incomplete development, or underdevelopment of the gallbladder. These conditions are typically present at birth and can lead to impaired bile storage and release, potentially causing digestive issues.

Apply this code when documentation clearly indicates a congenital anomaly of the gallbladder, such as agenesis (complete absence), aplasia (failure to develop), or hypoplasia (underdevelopment). This diagnosis is often made via imaging studies like ultrasound or MRI, or during surgical exploration.

• Ensure the documentation specifies a congenital anomaly of the gallbladder; acquired conditions are coded differently.
• Do not confuse with cholecystitis or cholelithiasis, which are common gallbladder diseases but not developmental anomalies.
• Sequence as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it's an underlying condition impacting treatment for another primary diagnosis.
