Injury of ulnar nerve at forearm level, left arm, subs

This code signifies a follow-up encounter for an injury to the ulnar nerve specifically located in the forearm of the patient's left arm. This injury could involve a contusion, laceration, or other trauma affecting the nerve's function in that region. The "subsequent encounter" indicates the patient is receiving routine care during the healing or recovery phase after the initial treatment.

Apply this code when documenting a patient's visit for ongoing management of a previously diagnosed ulnar nerve injury in the left forearm. This includes follow-up appointments for wound care, physical therapy, medication adjustments, or monitoring nerve recovery after an initial surgical or non-surgical intervention. It is appropriate for any encounter after the initial treatment of the acute injury.

• Ensure the documentation clearly specifies the left arm and forearm level for the ulnar nerve injury.
• Confirm the encounter type is for follow-up care, not the initial treatment of the injury.
• Always sequence this code after any applicable external cause codes (e.g., for the mechanism of injury) if still relevant to the current encounter.
