Disp fx of unsp tibial spine, subs for clos fx w malunion

This code describes a fracture of the tibial spine, which is a bony prominence on the top of the tibia (shin bone) within the knee joint, that has shifted from its normal anatomical position. The fracture is currently in a healing phase, but the bone segments have healed in an incorrect alignment, known as a malunion, and the skin over the fracture site remains intact.

Use this code for a patient presenting for follow-up care, rehabilitation, or management of complications related to a previously treated closed tibial spine fracture that has healed with an unsatisfactory alignment. This applies when the malunion is the primary focus of the current encounter.

• Ensure documentation clearly specifies "malunion" and that the fracture was initially "closed."
• This code is for a subsequent encounter, meaning the initial treatment for the acute fracture has already occurred.
• Confirm the fracture location is indeed the "unspecified tibial spine" if a more specific location (e.g., medial or lateral) is not documented.
