Contact with blunt object, undetermined intent, init encntr

This code signifies an injury resulting from impact with a blunt object where the circumstances surrounding the event are unclear or cannot be definitively determined as accidental, intentional self-harm, or assault. It indicates that the cause of the injury is unknown, but the mechanism involved a non-sharp object.

Apply this code when documentation clearly states an injury from a blunt object, but the provider cannot ascertain the intent (e.g., patient is unconscious, unreliable witness, or conflicting accounts). This is appropriate for the initial assessment and treatment of such an injury.

• Always ensure the "A" for initial encounter is appended for the first time a patient is seen for this injury.
• Only use when intent cannot be determined; avoid if intent (e.g., assault, accidental fall) is known.
• Pair with an external cause code (e.g., W50.-) to specify the type of blunt object if known, but not the intent.
