Lacerat extensor musc/fasc/tend finger at wrs/hnd lv, init

This code signifies a cut or tear affecting the extensor muscle, its surrounding fascia, and the tendon of any finger other than the thumb, specifically occurring at the wrist or hand level. This injury disrupts the structures responsible for straightening the affected finger.

Apply this code for acute injuries such as those sustained from sharp objects (e.g., knives, glass) that result in a laceration to the extensor mechanism of a finger (excluding the thumb) in the wrist or hand region. This code is appropriate for the initial treatment of such an injury.

• Ensure the documentation specifies "laceration" and not just a strain or sprain.
• Verify the injury location is at the wrist or hand level and involves an extensor structure of a finger other than the thumb.
• Confirm this is the initial encounter for treatment of this specific injury.
