Laceration of ulnar artery at forearm level, unsp arm, subs

This code signifies a tear or cut in the ulnar artery located in the forearm, with the specific arm not documented. This injury has been previously treated, and the patient is now presenting for follow-up care, such as wound checks, dressing changes, or evaluation of healing.

Apply this code when a patient returns for subsequent care related to a laceration of the ulnar artery in the forearm, and the medical record does not specify whether the injury was to the left or right arm. This is appropriate for encounters after the initial treatment phase, but while the patient is still receiving active care for the injury.

• Ensure the documentation clearly indicates a "subsequent encounter" for this specific injury.
• If the laterality (left or right arm) is documented, a more specific code should be used.
• Do not use for initial treatment of the injury or for sequelae (late effects) once active treatment has concluded.
