Laceration of ulnar artery at wrs/hnd lv of unsp arm, subs

This code signifies a laceration of the ulnar artery in the wrist or hand region of an unspecified arm. It indicates that the patient is receiving follow-up care for this injury after the initial treatment has been provided.

This code is appropriate for encounters where a patient is returning for ongoing management, such as wound checks, dressing changes, or evaluation of healing, following an initial laceration to the ulnar artery. It should be used after the acute phase of injury and initial surgical or medical intervention.

• Requires an additional code for the open wound itself (e.g., S61.409D).
• The "D" seventh character indicates a subsequent encounter for healing or follow-up.
• Ensure laterality (left or right arm) is not specified in the medical record for this "unspecified arm" code.
