Displ oblique fx shaft of unsp fibula, 7thR

This code signifies a malunion of a previously open, oblique fracture of the fibular shaft that was initially classified as an open fracture type IIIA, IIIB, or IIIC. Malunion indicates that the bone has healed, but in an unsatisfactory position, potentially leading to functional impairment. This code is used for encounters after the initial treatment phase, where the malunion is being addressed.

Apply this code when a patient presents for follow-up care, evaluation, or treatment of a malunited oblique fibular shaft fracture that was originally an open fracture (types IIIA, IIIB, or IIIC). This includes scenarios where surgical correction of the malunion is being planned or performed, or during ongoing management of the malunion's complications.

• Ensure documentation clearly specifies "malunion" and the original open fracture type (IIIA, IIIB, or IIIC).
• This code is for subsequent encounters; do not use for the initial treatment of the fracture.
• Verify laterality (left, right, or unspecified) is accurately reflected in the full code.
