Displ oblique fx shaft of unsp tibia, 7thR

This code describes a tibia shaft fracture that is angled (oblique) and has shifted out of alignment. It specifically indicates that the patient is in a subsequent phase of care for this fracture, which was initially an open fracture (meaning the skin was broken) classified as Type IIIA, IIIB, or IIIC, and has now healed incorrectly (malunion).

Use this code for follow-up encounters when a patient presents with a previously diagnosed displaced oblique fracture of the tibial shaft that was an open fracture (Type IIIA, IIIB, or IIIC) and has developed a malunion. This would apply during ongoing treatment, evaluation of the malunion, or planning for corrective procedures after the initial healing period.

• Ensure documentation clearly specifies "subsequent encounter" and confirms the initial open fracture type (IIIA, IIIB, or IIIC).
• Verify that the fracture is indeed a malunion, indicating abnormal healing.
• Laterality is unspecified in this code; if known, a more specific code should be sought.
