Abscess of liver

This code represents a localized collection of pus within the liver parenchyma, typically caused by bacterial infection. It signifies an inflammatory process resulting in tissue necrosis and suppuration within the liver.

Apply this code when documentation explicitly states "liver abscess" without further specification of an amebic origin. This diagnosis is often supported by imaging studies (e.g., ultrasound, CT scan) showing a focal fluid collection within the liver, along with clinical signs of infection.

• Differentiate from amebic liver abscess (A06.4), which is an Excludes1 condition.
• Ensure documentation specifies "abscess" of the liver, not just inflammation or hepatitis.
• Consider sequencing this code as a principal diagnosis if it is the primary reason for the encounter.
