Injury of unsp nerve at wrs/hnd lv of unsp arm, sequela

This code signifies a long-term consequence or late effect resulting from an unspecified nerve injury affecting the wrist or hand, where the specific arm involved is also not documented. It indicates that the initial acute injury has resolved, but the patient continues to experience residual symptoms or complications directly attributable to that past nerve damage.

This code is appropriate when a patient presents with chronic pain, numbness, weakness, or other neurological deficits in the wrist or hand, and the medical record clearly links these symptoms to a previously sustained, but now resolved, nerve injury. It should be used when the specific nerve affected (e.g., median, ulnar, radial) is not identified, and the laterality of the arm is also not specified.

• Always sequence this sequela code after the code for the specific condition or symptom being treated.
• Avoid using this code if the initial nerve injury is still acute or active; instead, use an acute injury code.
• Ensure documentation explicitly states "sequela" or indicates a chronic condition resulting from a past injury.
