Path fx in oth disease, l ankle, subs for fx w delay heal

This code signifies a fracture of the left ankle that occurred due to an underlying disease process, not from trauma. The fracture is currently in a phase of delayed healing, meaning it is taking longer than expected to unite. This is a follow-up encounter for the ongoing management of this specific fracture.

Use this code when documentation clearly indicates a left ankle fracture caused by a systemic disease (e.g., osteoporosis, metastatic cancer, Paget's disease) and the patient is presenting for follow-up care of this fracture, which is noted to be healing slowly. The encounter should focus on the continued treatment or assessment of the delayed healing.

• Ensure the documentation specifies "pathological" and identifies the underlying disease causing the fracture.
• Verify the laterality (left ankle) and the encounter type (subsequent encounter for fracture with delayed healing).
• Always sequence the underlying disease code first, followed by this code.
