Injury of unsp nerve at shldr/up arm, right arm, sequela

This code describes a long-term or late effect of an unspecified nerve injury located in the right shoulder or upper arm region. It indicates that the initial injury has resolved, but the patient continues to experience residual symptoms or complications directly attributable to that past nerve damage.

This code is appropriate for documenting chronic pain, weakness, numbness, or other persistent neurological deficits in the right upper extremity that are a direct consequence of a previous, unspecified nerve injury in the shoulder or upper arm. It is used when the acute phase of the injury has passed and the patient is being treated for the ongoing effects.

• Always sequence this sequela code after the code for the specific residual condition (e.g., chronic pain, muscle weakness).
• Ensure documentation clearly links the current symptoms to a past, unspecified nerve injury in the right shoulder/upper arm.
• Verify that the encounter is for the management of the long-term effects, not the initial acute injury.
