Nondisp pilon fx unsp tibia, subs for clos fx w malunion

This code describes a pilon fracture, which is a break at the weight-bearing surface of the tibia (shin bone) near the ankle joint, that is not displaced. In this specific instance, the fracture is located in an unspecified tibia and is being treated during a subsequent encounter where a malunion (improper healing) of a previously closed fracture has occurred.

Use this code for follow-up visits or ongoing treatment for a patient who sustained a closed, nondisplaced pilon fracture of an unspecified tibia, and the fracture has healed incorrectly, resulting in a malunion. This code would be appropriate when the patient is seen for complications or management related to this malunion.

• Always confirm the fracture's displacement, location, and encounter type.
• Ensure documentation clearly states "malunion" and that the fracture was previously closed.
• Verify laterality (left, right, or unspecified) if known, as more specific codes exist.
