Displ pilon fx unsp tibia, 7thQ

This code describes a specific type of tibia fracture where the lower end of the shin bone (pilon) is broken and the bone fragments are out of alignment (displaced). It specifies that this is an open fracture, meaning the skin was broken, and that the fracture is healing incorrectly (malunion) during a follow-up visit.

Use this code for a patient presenting for ongoing care of a previously diagnosed open pilon fracture of an unspecified tibia, where the fracture has healed in a misaligned position. This applies to follow-up encounters after initial treatment, such as for evaluation of malunion or planning for corrective surgery.

• Ensure documentation clearly specifies "displaced" and "malunion" for the pilon fracture.
• Confirm the encounter is for subsequent care of an open fracture type I or II.
• Do not use if the fracture is still acute or if the malunion is not explicitly documented.
