Pathological fracture, right ankle, subs for fx w malunion

This code signifies a fracture of the right ankle that occurred due to an underlying disease process, rather than trauma, and has healed incorrectly, resulting in a malunion. The "subsequent encounter" indicates the patient is receiving routine care during the healing phase of this already-diagnosed pathological fracture with a documented malunion.

Use this code when documentation specifies a right ankle fracture resulting from a pathological condition (e.g., osteoporosis, tumor, metabolic bone disease) that has subsequently healed in an unsatisfactory alignment. This applies to follow-up visits for ongoing management of the malunited pathological fracture. Documentation must clearly state "pathological fracture," "right ankle," "malunion," and indicate a subsequent encounter.

• Always confirm the laterality (right) and the specific bone involved in the ankle.
• Ensure documentation explicitly states "pathological fracture" and "malunion" to support this specific code.
• Do not use for initial encounters or for non-pathological fractures; different codes apply for those scenarios.
