Nondisp pilon fx unsp tibia, 7thQ

This code describes a pilon fracture, which is a break at the bottom of the tibia (shin bone) near the ankle joint, that is not displaced. This specific instance involves an open fracture (meaning the skin was broken) of either Type I or Type II, and the bone has healed in an incorrect anatomical position (malunion). This code is used for follow-up care after the initial treatment of the fracture.

Use this code for subsequent encounters when a patient presents with complications related to a previously treated nondisplaced pilon fracture of an unspecified tibia, specifically when malunion has occurred following an open fracture (Type I or II). This applies to visits for ongoing management, assessment of the malunion, or planning for corrective procedures.

• Ensure documentation clearly specifies "nondisplaced" and "malunion" in the context of an open pilon fracture (Type I or II).
• Verify that this is a subsequent encounter, not the initial treatment of the fracture.
• Confirm the laterality (left, right, or unspecified) of the tibia if available in the documentation; this code is for an unspecified tibia.
