Contusion of anus, subsequent encounter

This code signifies bruising or a superficial injury to the anal region that does not involve a break in the skin, occurring during a follow-up visit. It indicates a non-open wound injury to the perianal tissues.

Apply this code when a patient presents for ongoing care or evaluation of an anal contusion that was previously diagnosed and treated. This includes follow-up appointments to monitor healing, assess pain, or manage complications from the initial injury.

• Ensure documentation clearly states "subsequent encounter" or similar language indicating follow-up care.
• Verify the injury is a contusion and not an open wound or more severe trauma.
• Always sequence this code after the primary reason for the subsequent encounter, if applicable.
