Displ oblique fx shaft of r tibia, 7thR

This code describes a right tibia shaft fracture that is both displaced and oblique, meaning the break runs diagonally across the bone. The fracture was initially an open fracture (Type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination) and has subsequently healed incorrectly, resulting in malunion.

Use this code when documenting follow-up care for a patient whose right tibia shaft fracture, initially an open fracture with severe soft tissue involvement, has healed in a misaligned or deformed position. This applies to subsequent encounters where the malunion is being assessed or treated, rather than the initial injury or routine healing.

• Ensure documentation clearly specifies "malunion" and not "nonunion" (which would require a different code).
• Verify the original fracture was indeed an open fracture classified as Type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters; use an initial encounter code for the acute injury.
