Disp fx of unsp tibial spine, subs for clos fx w delay heal

This code signifies a fracture of the tibial spine (a bony prominence on the top of the tibia within the knee joint) that is no longer in its anatomical alignment. The fracture is currently undergoing a healing process that is taking longer than expected, and the bone is not exposed to the outside environment.

This code is appropriate for follow-up encounters where a patient is being managed for a previously diagnosed, displaced, closed tibial spine fracture that is demonstrating delayed union. This would apply when the physician documents that the fracture is not healing at the anticipated rate.

• Ensure documentation explicitly states "displaced" and "delayed healing" for a closed fracture.
• Verify that the encounter is a "subsequent encounter" and not the initial treatment.
• Do not use if the fracture is open, malunion, or nonunion; different codes apply for those scenarios.
