Nondisp seg fx shaft of humerus, unsp arm, init for opn fx

This code describes a fracture of the humerus (upper arm bone) that is broken in more than one place along the shaft, but the bone fragments are still in their normal alignment. It specifically indicates that the injury is an open fracture, meaning the skin and soft tissue were compromised, exposing the bone. The affected arm is not specified, and this code is for the initial treatment of the injury.

Use this code for a patient presenting with a new, acute segmental fracture of the humeral shaft where the fracture fragments are not displaced. This code is appropriate when documentation clearly indicates an open fracture and the specific arm (left or right) is not documented. It is used for the initial encounter for treatment of this specific injury.

• Ensure documentation specifies "segmental" and "nondisplaced" for the humeral shaft fracture.
• Confirm the fracture is explicitly documented as "open" to use this specific code.
• Only use this code for the initial treatment of the fracture; subsequent encounters will require different seventh characters.
