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

This code signifies a long-term or residual effect from a past injury to the median nerve in the upper arm, without specifying which arm was affected. It indicates that the initial acute injury has resolved, but the patient continues to experience symptoms or deficits directly attributable to that nerve damage.

Use this code when documenting a patient presenting with ongoing neurological symptoms, such as numbness, tingling, weakness, or motor deficits in the hand or forearm, that are a direct consequence of a previously sustained median nerve injury at the upper arm level. This applies when the original injury is no longer acute and the current encounter is for managing these chronic effects.

• Always ensure documentation clearly links the current symptoms to a past median nerve injury.
• This code requires a seventh character of "S" for sequela, indicating a late effect.
• Avoid using this code for acute injuries; instead, use the appropriate acute injury code with the "A" (initial encounter) or "D" (subsequent encounter) seventh character.
