Contusion of gallbladder, initial encounter

This code signifies a bruise or injury to the gallbladder, typically caused by blunt force trauma to the abdomen. It indicates damage to the gallbladder tissue without a full rupture or laceration, often presenting with pain and tenderness in the upper right quadrant.

Use this code for patients presenting with a documented contusion of the gallbladder following an acute traumatic event, such as a motor vehicle accident or a fall. This code is appropriate when the patient is receiving initial active treatment for the injury.

• Ensure documentation clearly specifies a contusion and not a laceration or rupture of the gallbladder.
• Confirm the "A" seventh character is appropriate for the initial encounter for active treatment.
• Always code any associated external cause of injury (e.g., W18.0XXA for fall on same level) to provide a complete picture of the event.
