Nondisp fx of med wall of r acetab, subs for fx w nonunion

This code signifies a fracture of the inner wall of the right hip socket that has not shifted out of alignment. Importantly, the fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care related to this ongoing issue.

Use this code when a patient with a previously diagnosed nondisplaced fracture of the medial wall of the right acetabulum presents for treatment or evaluation of a confirmed nonunion. This applies to subsequent visits after the initial treatment phase, where the nonunion is the primary focus of the encounter.

• Ensure documentation clearly states "nonunion" and specifies the "medial wall" of the "right acetabulum."
• Verify the fracture is explicitly described as "nondisplaced" in the medical record.
• This "K" seventh character indicates a subsequent encounter for a fracture with nonunion, not an initial treatment or routine healing follow-up.
