Nondisp Maisonneuve's fx r leg, 7thM

This code signifies a nondisplaced Maisonneuve's fracture affecting the right leg, which is a specific type of ankle fracture involving the proximal fibula and often associated with syndesmotic disruption. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, which was initially an open fracture of type I or II, and is now complicated by nonunion, meaning the bone is failing to heal properly.

Use this code for patients presenting for ongoing treatment of a right Maisonneuve's fracture that was originally an open fracture (Type I or II) and has since developed nonunion. This applies to scenarios such as follow-up appointments for monitoring healing, planning for revision surgery due to nonunion, or managing complications related to the nonunion.

• Ensure documentation clearly specifies "nondisplaced" and "right leg" for the Maisonneuve's fracture.
• Verify the initial injury was an "open fracture type I or II" and that "nonunion" is explicitly documented.
• Confirm this is a "subsequent encounter" and not the initial treatment for the fracture.
