Displ seg fx shaft of l tibia, 7thM

This code describes a specific type of fracture involving the shaft of the left tibia, where the bone is broken into multiple pieces (segmental) and the broken ends are not properly aligned (displaced). It specifically indicates that this is a follow-up encounter for an open fracture (meaning the skin was broken) classified as Type I or II, and the fracture has failed to heal properly (nonunion).

Use this code for subsequent encounters when a patient with a previously diagnosed open Type I or II segmental fracture of the left tibial shaft is being treated for nonunion. This applies when the initial injury has already been addressed, and the focus of the current encounter is the ongoing management of the unhealed fracture.

• Ensure documentation clearly specifies "segmental" and "displaced" for the fracture type.
• Verify that the encounter is for "nonunion" and not delayed union or malunion, as these have different codes.
• Confirm the initial fracture was an "open fracture type I or II" to align with the code's specificity.
