Injury to unspecified nerve of shoulder girdle and upper limb

This code signifies an injury to a nerve within the shoulder girdle or upper extremity when the specific nerve affected is not documented. It indicates a traumatic event resulting in nerve damage, such as a stretch, compression, or contusion, without further anatomical specificity. This diagnosis points to a generalized nerve injury in the upper limb region.

Use this code when documentation clearly states an injury to an unspecified nerve of the shoulder girdle or upper limb. This is appropriate when the physician's assessment identifies nerve damage but cannot pinpoint the exact nerve (e.g., "nerve injury to the arm," "shoulder nerve trauma"). Documentation should support a traumatic etiology and lack of further specificity.

• Avoid using this code if a more specific nerve injury (e.g., median nerve, ulnar nerve) is documented; always code to the highest level of specificity.
• Ensure the documentation explicitly states "unspecified nerve" or lacks the detail to identify a specific nerve.
• Consider external cause codes (E-codes) to describe the circumstances of the injury, if available.
