Disp fx of medial wall of left acetabulum, sequela

This code describes a past injury involving a displaced fracture of the inner wall of the left hip socket (acetabulum) that is now causing a current problem or condition. The fracture itself is no longer acute, but its lasting effects are being addressed.

Use this code when documenting a patient presenting with a complication or residual effect directly attributable to a previously sustained and healed, or non-healing, displaced fracture of the medial wall of the left acetabulum. This would include conditions like chronic pain, malunion, nonunion, or post-traumatic arthritis stemming from the original injury.

• Requires an additional code to specify the nature of the sequela (e.g., M24.552 for contracture, M16.4 for post-traumatic osteoarthritis).
• Do not use for initial or subsequent encounters for active fracture treatment.
• Ensure documentation clearly links the current condition to the past fracture.
