Contusion of ascending [right] colon, subsequent encounter

This code signifies a bruise or injury to the ascending (right) portion of the large intestine that occurred previously and is now being treated or evaluated again. It indicates that the initial injury has already been addressed, and the patient is presenting for follow-up care, monitoring, or treatment of ongoing issues related to the contusion.

Use this code when a patient returns for a scheduled follow-up appointment after an initial diagnosis and treatment of an ascending colon contusion. It is also appropriate for subsequent visits where complications or persistent symptoms from the original injury are being managed. This code is not for the initial presentation of the injury.

• Ensure documentation clearly states the encounter is subsequent to the initial injury.
• Verify the specific location of the contusion is the ascending colon.
• Do not use for initial treatment; that requires an 'A' (initial encounter) seventh character.
