Lacerat extn musc/fasc/tend l idx fngr at wrs/hnd lv, subs

This code signifies a tear or cut in the extensor muscle, its surrounding fascia, and the tendon of the left index finger. The injury is located specifically at the wrist or hand level, indicating involvement of the structures responsible for extending the index finger.

This code is appropriate for follow-up encounters for a patient who has previously received initial treatment for a laceration of the extensor muscle, fascia, and tendon of the left index finger. This includes visits for wound care, monitoring healing, physical therapy, or management of complications after the initial injury.

• Ensure the documentation clearly specifies the left index finger and the wrist/hand level for the laceration.
• Confirm this is a subsequent encounter, not the initial treatment for the injury.
• Verify that the injury involves the extensor muscle, fascia, and tendon, not just superficial skin.
