Lacerat extn musc/fasc/tend r 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 right index finger. The injury is located specifically at the wrist or hand level, and the patient is presenting for follow-up care after the initial treatment of the laceration.

Use this code for subsequent encounters when a patient receives follow-up care for a previously diagnosed and treated laceration of the extensor structures of the right index finger at the wrist or hand. This includes visits for wound checks, dressing changes, physical therapy, or monitoring healing progress after the initial injury.

• Ensure the documentation specifies "subsequent encounter" for this specific injury.
• Verify the injury location is precisely at the wrist or hand level of the right index finger.
• Confirm the laceration involves the extensor muscle, fascia, and tendon, not just superficial skin.
