Displ oblique fx shaft of unsp fibula, 7thN

This code signifies a non-healing oblique fracture located in the shaft of an unspecified fibula, which was initially an open fracture of type IIIA, IIIB, or IIIC. The fracture fragments are no longer in their normal anatomical alignment.

This code is appropriate for subsequent encounters when a patient presents with a previously diagnosed open oblique fibula shaft fracture (types IIIA, IIIB, or IIIC) that has failed to unite and remains displaced. It indicates ongoing management of a complicated fracture that is not progressing to healing.

• Ensure documentation clearly specifies "nonunion" and "displaced" for the fibula shaft fracture.
• Verify the original open fracture type (IIIA, IIIB, or IIIC) is documented to support the 'N' seventh character.
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
