Displ spiral fx shaft of unsp tibia, 7thR

This code describes a displaced spiral fracture of the shaft of the tibia, where the bone has broken in a spiral pattern and the fractured ends are not properly aligned. It specifically indicates that this is a subsequent encounter for an open fracture (meaning the skin was broken) classified as type IIIA, IIIB, or IIIC, and that the fracture has healed in an unsatisfactory position (malunion).

Use this code when documenting follow-up care for a patient who previously sustained a severe open spiral fracture of the tibial shaft, and imaging or clinical assessment confirms that the fracture has healed with a deformity. This code is appropriate for ongoing management of the malunion, such as planning for corrective surgery or managing associated complications.

• Ensure documentation clearly specifies a "subsequent encounter" and the presence of "malunion."
• Verify the original open fracture was classified as type IIIA, IIIB, or IIIC.
• This code is for an unspecified tibia; if left or right is known, a more specific code should be used.
