Displ bimalleol fx unsp low leg, 7thF

This code describes a fracture involving both the medial and lateral malleoli of an unspecified lower leg, which has been surgically exposed to the environment (open fracture type IIIA, IIIB, or IIIC). The patient is in a subsequent phase of care, and the fracture is healing as expected without complications.

Use this code for follow-up encounters where a patient is receiving ongoing treatment for a previously diagnosed displaced bimalleolar open fracture (Gustilo-Anderson type IIIA, IIIB, or IIIC) of an unspecified lower leg, and the healing process is progressing routinely. This applies to visits for cast changes, wound care, or physical therapy during the routine healing period.

• Ensure the documentation specifies an "unspecified lower leg" and confirms the open fracture type (IIIA, IIIB, or IIIC).
• Verify that the encounter is "subsequent" and that healing is described as "routine."
• Do not use this code if the fracture is closed, if only one malleolus is fractured, or if the healing is complicated.
