Disp fx of unsp tibial tuberosity, 7thQ

This code describes a situation where a fracture of the tibial tuberosity, the bony prominence below the kneecap, has healed incorrectly (malunion) after an initial injury. The fracture was displaced, meaning the bone fragments were out of alignment, and the original injury was an open fracture of either Type I or Type II severity.

This code is used for follow-up encounters when a patient presents with complications from a previously treated open tibial tuberosity fracture, specifically when imaging confirms malunion. It indicates ongoing care for a fracture that has not healed optimally, requiring further medical attention or intervention.

• Ensure documentation clearly states "malunion" and specifies the original injury as an "open fracture type I or II."
• Verify that the encounter is for follow-up care related to the malunion, not the initial treatment of the acute fracture.
• Confirm the fracture was displaced; if not, a different code for nondisplaced malunion would be appropriate.
