Injury of digital nerve of right thumb, initial encounter

This diagnosis code signifies damage to a nerve in the right thumb, specifically one of the digital nerves responsible for sensation and motor function. This injury can result in numbness, tingling, weakness, or pain in the affected thumb.

Apply this code when documenting an initial presentation of a patient with a confirmed injury to a digital nerve of their right thumb. This includes cases such as lacerations, crush injuries, or severe contusions affecting the nerve. It is appropriate for the initial treatment phase of the injury.

• Ensure documentation specifies the right thumb and confirms nerve involvement.
• Verify that this is the initial encounter for this specific injury. Subsequent encounters will require a different seventh character.
• Look for supporting documentation such as physical exam findings (e.g., sensory deficits) or nerve conduction studies.
