Displ oblique fx shaft of l tibia, 7thQ

This code signifies a left tibia shaft fracture that is both displaced and oblique, meaning the bone fragments are not aligned and the break runs diagonally across the bone. The fracture was initially an open fracture (Type I or II), and the current encounter addresses a malunion, where the bone has healed in an incorrect anatomical position.

Use this code for follow-up encounters where a patient with a previously treated open, displaced, oblique fracture of the left tibial shaft is presenting with complications related to malunion. This applies when the malunion is being assessed, monitored, or treated, and the original fracture was an open Type I or II.

• Ensure documentation specifies "malunion" as the reason for the subsequent encounter, not just a healing fracture.
• Verify the laterality (left tibia) and the specific fracture type (oblique, shaft, displaced).
• Confirm the original fracture was an open Type I or II, as this impacts the seventh character.
