Displaced intartic fx unsp calcaneus, subs for fx w malunion

This code signifies a fracture within the joint surface of the heel bone (calcaneus) that has shifted from its normal position. The patient is in a subsequent phase of care, and the fracture has healed in an imperfect alignment, known as a malunion.

This code is appropriate for follow-up encounters where a patient is being treated for complications arising from a previously sustained displaced intraarticular calcaneal fracture, specifically when imaging confirms a malunion. It would be used after the initial acute treatment phase, during ongoing management of the malaligned healing.

• Ensure documentation clearly states "malunion" and specifies "subsequent encounter" for this fracture type.
• Verify the fracture is intraarticular and displaced, as opposed to extraarticular or non-displaced.
• Confirm the laterality is unspecified; if left or right is documented, a more specific code should be chosen.
