Nondisp oblique fx shaft of unsp fibula, 7thC

This code describes a break in the shaft of the fibula that runs diagonally (oblique) and where the bone fragments remain in their normal alignment (nondisplaced). It specifically indicates that the fracture is open, meaning the bone has broken through the skin, and is classified as a severe open fracture (Type IIIA, IIIB, or IIIC) according to the Gustilo-Anderson classification. This code is used for the initial treatment of such an injury when the specific fibula (left or right) is not documented.

This code is appropriate for the initial encounter for an open oblique fibular shaft fracture where the laterality is unspecified and the fracture is nondisplaced. It should be used when the physician explicitly documents the Gustilo-Anderson classification as Type IIIA, IIIB, or IIIC. This code is typically assigned in emergency department settings or during the initial hospitalization for the injury.

• Ensure documentation clearly specifies "nondisplaced" and "oblique" for the fibular shaft fracture.
• Verify the Gustilo-Anderson classification (Type IIIA, IIIB, or IIIC) is explicitly stated for the open fracture.
• Only use this code for the initial encounter; subsequent encounters will require a different seventh character.
