Unsp injury of ulnar art at wrs/hnd lv of left arm, sequela

This code signifies a long-term complication or late effect resulting from an unspecified injury to the ulnar artery in the left wrist or hand. It indicates that the initial injury has resolved, but the patient continues to experience residual issues directly attributable to that past trauma.

Use this code when documenting a patient presenting with ongoing symptoms such as chronic pain, numbness, weakness, or circulatory issues in the left hand or wrist, and the medical record clearly links these symptoms to a previously sustained, unspecified ulnar artery injury. This code is appropriate when the acute phase of the original injury has passed, and the current encounter addresses the lasting consequences.

• Always ensure documentation explicitly states the condition is a "sequela" or "late effect" of a previous injury.
• Verify that the injury location is specifically the ulnar artery at the wrist or hand level of the left arm.
• Do not use this code for acute injuries; instead, use the appropriate acute injury code.
