Unsp fracture of shaft of humerus, left arm, init for opn fx

This code signifies a fracture of the main part of the left upper arm bone, where the bone has broken through the skin, and the specific type of fracture is not documented. This is the initial visit for treatment of this open injury.

Apply this code for a patient presenting with an open fracture of the left humeral shaft when the medical record does not specify the fracture type (e.g., transverse, oblique, spiral). This code is appropriate for the first encounter where definitive treatment for the fracture is provided.

• Ensure documentation clearly states "left arm" and "open fracture" for accurate code assignment.
• Only use this code for the initial treatment encounter; subsequent care will require a different encounter character.
• If the fracture type is later identified, a more specific code should be used.
