Lacerat extn musc/fasc/tend l rng fngr at wrs/hnd lv, init

This code signifies a tear or cut through the extensor muscle, its surrounding fascia, and the tendon of the left ring finger. The injury is located specifically at the wrist or hand level, indicating damage to the structures responsible for extending the ring finger. This is an initial encounter for the injury.

Use this code for patients presenting with a fresh laceration to the extensor mechanism of their left ring finger, affecting the muscle, fascia, and tendon. This would typically be seen in acute trauma cases, such as cuts from sharp objects or machinery, where the wound is open and requires initial treatment.

• Ensure the documentation specifies the left ring finger and the involvement of all three structures: muscle, fascia, and tendon.
• Verify the injury location is at the wrist or hand level, not more proximally in the forearm.
• Confirm this is the initial encounter for treatment of this specific injury; subsequent encounters will require different seventh characters.
