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

This code signifies a long-term or residual effect stemming from a previous injury to the median nerve in the left wrist or hand. It indicates that the initial acute injury has resolved, but the patient continues to experience symptoms or deficits directly attributable to that past nerve damage. These sequelae can include persistent pain, numbness, weakness, or functional impairment in the distribution of the median nerve.

Use this code when documenting a patient presenting with ongoing neurological symptoms in the left hand or wrist that are directly linked to a prior, resolved injury of the median nerve. This applies to follow-up encounters where the focus is on managing the chronic effects of the nerve damage, rather than the acute injury itself. Examples include persistent carpal tunnel syndrome symptoms after a traumatic wrist injury, or long-term sensory deficits following a laceration that affected the median nerve.

• Always ensure documentation clearly links the current symptoms to a previous median nerve injury.
• Verify the laterality (left arm) and the specific anatomical level (wrist and hand) are accurately reflected.
• Remember the "S" seventh character indicates sequela, meaning the initial injury has healed but its effects persist.
