Lacerat extn musc/fasc/tend r idx fngr at forarm lv, init

This code signifies a tear or cut involving the extensor muscle, its surrounding fascia, and the tendon of the right index finger. The injury is located specifically at the forearm level, indicating damage proximal to the wrist joint. This type of injury can impair the ability to extend the right index finger.

Use this code for acute traumatic lacerations affecting the extensor structures of the right index finger in the forearm region. This is appropriate for the initial treatment of such an injury, such as in an emergency department or during the first surgical repair. It would be used when a patient presents with a fresh wound and associated functional deficit.

• Ensure the documentation specifies the right index finger and the forearm level of the injury.
• Verify that the injury involves the extensor muscle, fascia, and tendon, not just superficial skin.
• The "A" suffix indicates an initial encounter for active treatment of the injury.
