Lacerat flexor musc/fasc/tend l idx fngr at wrs/hnd lv, init

This diagnosis code signifies a deep, irregular tear affecting the flexor muscle, its surrounding fascia, and the associated tendon of the left index finger. The injury is located specifically within the wrist and hand region, indicating involvement proximal to the finger itself but distal to the forearm. This type of laceration often results in significant functional impairment of the index finger.

This code is appropriate for documenting an initial encounter for a patient presenting with a confirmed laceration of the flexor structures of the left index finger at the wrist or hand level. This includes injuries sustained from sharp objects, machinery, or other trauma causing a deep cut. It should be used when the patient is receiving active treatment for the acute injury.

• Ensure documentation specifies "left index finger" and the "wrist and hand level" to support this specific code.
• Confirm the injury involves the flexor muscle, fascia, AND tendon; if only one or two structures are involved, a different code may be more appropriate.
• The "A" suffix indicates an initial encounter for active treatment; subsequent encounters will require different seventh characters.
