Injury of digital nerve of left thumb, subsequent encounter

This code signifies a documented injury to a digital nerve of the left thumb, indicating damage to the nerve responsible for sensation or motor function in that digit. The "subsequent encounter" designation means this code is used for follow-up care after the initial treatment of the injury.

Apply this code when a patient presents for ongoing management, rehabilitation, or evaluation of a previously diagnosed digital nerve injury of the left thumb. This includes visits for wound care, pain management, physical therapy, or assessment of nerve recovery after the initial injury has been addressed.

• Ensure documentation clearly specifies the left thumb and a digital nerve injury.
• The "X" placeholder indicates the specific digit is not further specified beyond the thumb.
• Confirm the encounter is for follow-up care, not the initial treatment, to justify the "D" seventh character.
