Path fracture in oth disease, r foot, subs for fx w nonunion

This code signifies a fracture of the right foot that occurred due to an underlying disease process, not from trauma. The fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care related to this unhealed fracture.

Apply this code when a patient with a pre-existing condition (e.g., osteoporosis, bone tumor) presents for ongoing management of a right foot fracture that has not united. Documentation should clearly state "pathological fracture," specify the right foot, confirm nonunion, and indicate a subsequent encounter.

• Always identify the underlying disease causing the pathological fracture and code it first.
• Distinguish between initial, subsequent, and sequela encounters based on the patient's current phase of care.
• Ensure documentation explicitly states "nonunion" for accurate coding of the healing status.
