Nondisp oblique fx shaft of l tibia, 7thR

This code describes a specific type of healing complication for an open oblique fracture of the shaft of the left tibia. Specifically, it indicates that the fracture, which was initially open (type IIIA, IIIB, or IIIC), has healed in a misaligned position (malunion) and the patient is being seen for follow-up care. The fracture itself is nondisplaced, meaning the bone fragments are still in their anatomical alignment despite the oblique break.

Use this code when documenting a subsequent encounter for a patient with a previously diagnosed open oblique fracture of the left tibial shaft that has resulted in malunion. This applies to follow-up visits where the malunion is being assessed, monitored, or managed, and the initial open fracture was classified as type IIIA, IIIB, or IIIC. This code is appropriate for ongoing care after the initial treatment of the acute fracture.

• Ensure documentation clearly specifies "malunion" and not "nonunion" for accurate code selection.
• Verify the laterality (left tibia) and the specific fracture type (oblique, shaft) are documented.
• Confirm the original open fracture was classified as type IIIA, IIIB, or IIIC, as this impacts code specificity.
