Fx rad/ulna fol insrt ortho implnt/prosth/bone plt, left arm

This code describes a fracture of the radius or ulna in the left arm that occurs as a complication following the surgical implantation of an orthopedic device, such as a joint prosthesis, internal fixation plate, or other orthopedic implant. This is an iatrogenic fracture directly related to the presence or insertion of the implant.

Use this code when documentation clearly indicates a new fracture of the left radius or ulna that developed after an orthopedic implant was placed. This typically occurs during or shortly after the initial surgery, or as a late complication due to stress around the implant. Physician documentation should specify the anatomical location (left radius or ulna) and the causal relationship to the implant.

• Always sequence this code after the primary reason for the encounter, if applicable, or as the principal diagnosis if the fracture is the sole reason for admission.
• Do not use this code for pathological fractures unrelated to an implant or for traumatic fractures in an arm with a pre-existing implant if the implant did not cause the fracture.
• Ensure documentation specifies "left arm" and the type of implant involved to support the specificity of this code.
