Oth nondisp fx of lower end of unsp humerus, init for opn fx

This code describes a fracture at the lower end of the humerus (the bone of the upper arm) that is not displaced, meaning the bone fragments are still in their normal alignment. It specifically indicates that the fracture is open, meaning there is a break in the skin communicating with the fracture site, and this is the initial treatment encounter for the injury. The exact side (left or right) of the humerus is not specified.

Use this code for a patient presenting for the first time with an open, nondisplaced fracture of the distal humerus where the laterality is not documented. This would apply to initial evaluations, surgical repair, or other definitive treatment for the acute injury.

• Ensure documentation clearly states "nondisplaced" and "open fracture" for the lower end of the humerus.
• If laterality (left or right) is specified in the medical record, a more specific code should be used.
• This "initial encounter" code is only for the period when the patient is receiving active treatment for the fracture.
