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

This code signifies a tear or cut in the extensor muscles, their surrounding fascia, and/or the tendons responsible for extending the left thumb. The injury is specifically located within the wrist and hand region. This type of injury can impair the patient's ability to straighten their thumb.

Use this code for a patient presenting with an acute injury involving a laceration to the extensor structures of the left thumb, such as from a knife cut or a deep penetrating wound. This code is appropriate for the initial treatment of such an injury, including examination, repair, or initial management.

• Ensure the documentation clearly specifies the left thumb and the extensor structures are involved.
• Verify the injury is a laceration (cut/tear) and not a strain or sprain.
• Confirm this is the patient's initial encounter for this specific injury. Subsequent encounters will require a different seventh character.
