Injury of radial nerve at upper arm level, unsp arm, sequela

This code signifies a long-term or late effect resulting from a past injury to the radial nerve in the upper arm. It indicates that the specific arm affected (left or right) is not documented. This sequela could manifest as persistent weakness, sensory deficits, or pain in the distribution of the radial nerve.

Use this code when documenting a current condition that is a residual effect of a previous radial nerve injury at the upper arm level, and the laterality of the arm is not specified in the medical record. This applies to conditions like chronic wrist drop, persistent numbness, or muscle atrophy directly attributable to the past nerve damage.

• Always ensure the documentation clearly links the current condition to a previous radial nerve injury.
• Verify that the arm laterality is truly unspecified; if specified, a more precise code should be used.
• Remember to use an external cause code (V00-Y99) if the original injury's cause is known and relevant.
