Struck by orca, subsequent encounter

This code indicates a patient presenting for follow-up care related to an injury sustained from being struck by an orca. It signifies that the initial encounter for the injury has already been coded, and this visit is for continued management, assessment of healing, or addressing complications. The nature of the injury itself would be coded separately.

Use this code for any subsequent visit where the primary reason for the encounter is ongoing care for an injury caused by an orca strike. This includes follow-up appointments for wound care, fracture management, physical therapy, or re-evaluation of any other sequelae directly resulting from the initial incident. Do not use for the initial presentation of the injury.

• Always pair this external cause code with an injury code describing the specific nature of the trauma (e.g., fracture, open wound).
• Ensure the seventh character "D" is correctly applied for subsequent encounters.
• Verify the encounter is indeed subsequent and not an initial or sequela encounter.
