Injury of digital nerve of right thumb, subsequent encounter

This code signifies a documented injury to a digital nerve supplying the right thumb, indicating damage to the nerve responsible for sensation and potentially motor function in that digit. This injury could result in numbness, tingling, pain, or weakness in the right thumb.

This code is appropriate for follow-up visits, subsequent care, or rehabilitation encounters related to an initial injury of the digital nerve of the right thumb. It should be used when the patient is receiving active treatment for the nerve injury after the initial encounter for the acute injury.

• Ensure documentation specifies the right thumb and confirms the "subsequent encounter" status.
• Verify that the injury is to a digital nerve, not a more proximal nerve of the hand or wrist.
• Always sequence this code after any applicable external cause codes (e.g., W00-Y38) if the cause of the injury is still relevant to the current encounter.
