Nondisp fx of post column of r acetab, 7thK

This code signifies a fracture of the posterior column of the right acetabulum, specifically the ilioischial portion, where the bone fragments are still in their anatomical position. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and the "nonunion" specifies that the fracture has failed to heal properly.

This code is appropriate for documenting ongoing management of a previously diagnosed nondisplaced posterior column acetabular fracture on the right side. It should be used when the physician has determined, through imaging or clinical assessment, that the fracture has not united and the patient is presenting for further treatment, such as surgical intervention for nonunion or continued conservative management.

• Ensure documentation clearly states "nondisplaced" and specifies the "posterior column [ilioischial]" of the right acetabulum.
• Verify that the encounter is for follow-up care of the fracture and that nonunion has been explicitly diagnosed.
• Do not use for initial encounters or for fractures that have healed or are in the process of routine healing.
