Injury of ulnar nerve at forearm level, right arm, init

This code signifies a traumatic injury to the ulnar nerve specifically located in the right forearm. Such an injury can result in sensory deficits (numbness, tingling) and motor weakness in the hand, particularly affecting the little finger and half of the ring finger, as well as intrinsic hand muscles. This code is used for the initial phase of treatment for this specific nerve damage.

Apply this code for patients presenting with a new injury to the ulnar nerve in their right forearm, such as from a laceration, fracture, or direct blunt trauma. It is appropriate for the initial evaluation and management of the acute injury. This code would be used for the first encounter where the injury is diagnosed and treatment plans are initiated.

• Ensure documentation specifies "right arm" and "forearm level" for the ulnar nerve injury.
• Confirm the encounter is indeed the "initial encounter" for this specific injury; subsequent care would use a different seventh character.
• Look for associated injuries, such as fractures, which would require additional coding.
