Injury of nerves at wrist and hand level of left arm, init

This code signifies damage to any peripheral nerve in the left wrist or hand, excluding the median, ulnar, or radial nerves. This could involve smaller, named nerves or unnamed branches that are not specifically categorized elsewhere. The injury is acute and represents the initial phase of treatment.

Apply this code when a patient presents with a new injury to a nerve in the left wrist or hand, and the specific nerve affected is not the median, ulnar, or radial nerve. Examples include trauma resulting in damage to a digital nerve, a dorsal cutaneous nerve, or other less common nerve structures in this anatomical region. This code is appropriate for the initial evaluation and management of such an injury.

• Ensure the laterality is correctly identified as left arm.
• Verify that the nerve injured is not the median, ulnar, or radial nerve; if it is, a more specific code should be used.
• Confirm this is the patient's initial encounter for this specific injury; subsequent encounters will require a different seventh character.
