Injury of radial nerve at forearm level, left arm, sequela

This code describes a long-term or late effect of a past injury to the radial nerve in the left forearm. This could manifest as persistent weakness, sensory deficits, or pain in the distribution of the radial nerve, which supplies muscles responsible for wrist and finger extension, and sensation over parts of the hand.

Use this code when documenting a current condition directly resulting from a previous injury to the radial nerve in the left forearm, even if the original injury has healed. This is appropriate for follow-up visits addressing ongoing symptoms like wrist drop, numbness, or paresthesia attributed to the prior nerve damage.

• Always sequence this sequela code after the code for the specific manifestation of the nerve injury (e.g., muscle weakness, sensory loss).
• Ensure documentation clearly links the current radial nerve deficit to a past injury of the left forearm.
• The "S" at the end indicates "sequela," meaning it's used for complications or conditions arising as a direct result of a previous injury or disease.
