Lacerat extn musc/fasc/tend l mid finger at forarm lv, init

This code signifies a tear or cut through the extensor muscle, its surrounding fascia, and the associated tendon of the left middle finger. The injury is located specifically at the forearm level, indicating the damage extends proximally from the hand.

Apply this code for patients presenting with an acute, open injury to the extensor mechanism of the left middle finger, where the laceration involves all three tissue layers (muscle, fascia, and tendon) and is situated in the forearm region. This would be used for the initial treatment of such an injury.

• Ensure documentation specifies the left middle finger and the forearm level of the injury.
• Verify that all three tissue types (muscle, fascia, tendon) are explicitly documented as lacerated.
• Confirm this is the patient's initial encounter for this specific injury.
