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

This code signifies a long-term or residual effect resulting from a past injury to an unspecified nerve in the left wrist or hand. This could manifest as chronic pain, numbness, weakness, or altered sensation that persists after the initial acute phase of nerve damage has resolved. The specific nerve involved is not documented or identifiable.

Apply this code when documenting a patient presenting with ongoing neurological deficits in the left wrist or hand, and the medical record clearly indicates these are sequelae of a prior nerve injury. This is appropriate when the exact nerve affected was not specified in the original injury documentation or cannot be determined at the time of follow-up.

• Always use this code with an additional code to specify the nature of the sequela (e.g., chronic pain, muscle weakness).
• Ensure documentation clearly states the condition is a "sequela" or "late effect" of a previous injury.
• Verify that the injury occurred at the wrist or hand level of the left arm.
