Fx humerus fol insrt ortho implnt/prosth/bone plt, unsp arm

This code signifies a fracture of the humerus that occurs after an orthopedic implant, joint prosthesis, or bone plate has been surgically placed in the arm. It specifically indicates that the fracture is a complication directly related to the presence of the previously implanted device, rather than a new traumatic injury to an intact bone. The exact arm affected is not specified.

This code is appropriate when documentation clearly states a humeral fracture has occurred in the presence of a prior orthopedic implant, prosthesis, or bone plate, and the specific arm (left or right) is not documented. This typically arises in scenarios such as periprosthetic fractures or fractures around existing hardware. Documentation should explicitly link the fracture to the presence of the implant.

• Ensure documentation specifies the fracture is following the insertion of an orthopedic device, not a new fracture in an un-operated bone.
• If the specific arm (left or right) is documented, a more specific code from the M96.62- series should be used.
• This code requires an external cause code (e.g., W19.XXXA for unspecified fall) if the cause of the fracture is known.
