Unsp injury of ulnar artery at forearm level, left arm, init

This code signifies an injury to the ulnar artery in the left forearm where the specific nature or type of the injury (e.g., laceration, contusion, rupture) is not documented. It indicates the initial treatment or evaluation for this vascular trauma.

Apply this code when a patient presents with a suspected or confirmed injury to the ulnar artery in the left forearm, but the medical record lacks precise details about the injury's morphology. This is appropriate for the initial encounter when the full extent or type of arterial damage is still being assessed or is simply not specified.

• Ensure the documentation clearly specifies the left arm and forearm level.
• Only use this code when the type of ulnar artery injury is truly unspecified. If a more specific injury (e.g., laceration) is documented, a more precise code should be selected.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
