2-part nondisp fx of surg nk of unsp humer, init for opn fx

This code describes a fracture involving the surgical neck of the humerus that has not shifted out of alignment and is broken into two main pieces. It specifically indicates that the skin and soft tissues overlying the fracture site are also compromised, exposing the bone to the external environment. This code is used for the initial treatment of such an injury.

Apply this code when documenting the initial encounter for an open, nondisplaced, 2-part fracture of the surgical neck of the humerus, where the laterality (left or right) is not specified in the medical record. This would be appropriate for emergency department visits, initial hospital admissions, or the first outpatient visit for definitive treatment of the open fracture.

• Ensure documentation clearly states "open fracture" and "initial encounter."
• Verify that the fracture is described as "nondisplaced" and "2-part" at the surgical neck.
• Only use this code when the laterality of the humerus is explicitly unspecified in the medical record. If laterality is known, a more specific code should be chosen.
