Nondisp fx of post wl of r acetab, subs for fx w delay heal

This code signifies a fracture of the back portion of the right hip socket that has not shifted out of alignment. The patient is in a later stage of care, and the fracture is not healing at the expected rate.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed nondisplaced posterior acetabular fracture of the right hip is experiencing delayed union. It should be used when the physician documents that the fracture healing is progressing slower than anticipated, but the patient is still receiving active treatment for the fracture.

• Ensure documentation explicitly states "delayed healing" for the fracture.
• Verify the fracture is specifically of the "posterior wall" and "nondisplaced."
• Confirm this is a "subsequent encounter" and not the initial treatment.
