Contact w unsp sharp object, undetermined intent, subs

This code signifies an injury resulting from contact with an unidentifiable sharp object where the intent of the injury (accidental, self-harm, assault) cannot be determined. The "D" seventh character indicates that this is a subsequent encounter, meaning the patient is receiving follow-up care for the initial injury.

This code is appropriate for documenting follow-up visits for patients who presented with a sharp object injury of unknown intent, such as a puncture wound from an unidentified sharp object found in the environment. It should be used when the provider is unable to ascertain if the injury was accidental, intentional self-harm, or assault.

• Ensure the "D" seventh character is used only for subsequent encounters after the initial treatment of the injury.
• Always seek to clarify the intent of the injury if possible, as more specific codes exist for accidental, intentional, or assault-related injuries.
• This code should be accompanied by a code for the specific type of injury sustained (e.g., puncture wound, laceration).
