Contusion of liver, subsequent encounter

This code signifies a bruise or bleeding within the liver tissue that occurred during a previous encounter. It indicates that the patient is presenting for follow-up care, monitoring, or treatment related to this previously diagnosed liver injury. The contusion can range in severity, from minor subcapsular hematomas to more significant parenchymal damage.

Apply this code when a patient returns for subsequent evaluation of a liver contusion that was initially diagnosed and treated in a prior encounter. This includes visits for imaging follow-up, assessment of healing, or management of ongoing symptoms related to the injury. It is appropriate for any encounter after the initial diagnosis and treatment.

• Ensure documentation clearly states the encounter is for follow-up of a previously diagnosed liver contusion.
• Always assign an external cause code (V, W, X, Y category) to describe the circumstances of the injury, if not already documented from the initial encounter.
• Verify the seventh character "D" is appropriate for subsequent care; "A" is for initial encounters and "S" for sequelae.
