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

This code signifies a tear or cut in the extensor muscle, its surrounding fascia, or the extensor tendon of an unspecified finger. The injury is located at the wrist or hand level and represents the initial treatment for this specific laceration.

This code is appropriate for documenting the initial presentation and treatment of a patient who has sustained a laceration affecting the extensor structures of an unknown finger, such as from a sharp object. It should be used when the specific finger involved (e.g., thumb, index) is not documented or cannot be determined.

• Ensure documentation specifies "unspecified finger" if the exact digit is not identified.
• Verify the injury is a laceration (cut) and not a rupture or avulsion, as different codes apply.
• Confirm this is the initial encounter for this specific injury; subsequent encounters will use a different 7th character.
