Displ oblique fx shaft of unsp fibula, 7thM

This code signifies a specific type of fibula fracture: an oblique break in the shaft that is displaced. It's used when the fracture was initially an open wound (Type I or II) and is now experiencing nonunion, meaning it's failing to heal properly. This particular code is for a subsequent encounter, indicating ongoing treatment for the nonunion.

Use this code for patients presenting for follow-up care, evaluation, or treatment of a previously diagnosed displaced oblique fibular shaft fracture that was initially open and is now complicated by nonunion. This applies when the fibula involved is not specified (e.g., left or right). It's appropriate for encounters where the focus is on managing the nonunion of this specific fracture type.

• Ensure the documentation clearly states "nonunion" and that the initial fracture was an "open" type I or II.
• Verify that the fracture is specifically described as "oblique" and "displaced" in the shaft of the fibula.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
