Injury of peritoneum, subsequent encounter

This code signifies an injury to the peritoneum, the membrane lining the abdominal cavity and covering its organs, that is being treated or monitored after the initial phase of care. It indicates that the patient is receiving follow-up care for a previously diagnosed peritoneal injury, which could include complications, healing assessment, or ongoing management.

This code is appropriate for encounters where a patient is seen for continued care of a peritoneal injury, such as during a post-operative visit following repair of a peritoneal laceration, or for monitoring a peritoneal hematoma. It applies when the patient is no longer in the acute phase of treatment but still requires medical attention related to the original injury.

• Ensure the encounter is for follow-up care, not the initial treatment of the injury.
• Always use in conjunction with an external cause code (e.g., Y90-Y99) to describe the circumstances of the injury.
• Do not use for sequelae (late effects) of the injury; a specific sequela code would be more appropriate if applicable.
