Path fx in oth disease, hip, unsp, subs for fx w delay heal

This code signifies a hip fracture that occurred due to an underlying disease process, rather than trauma, and is currently in a phase of delayed healing. It indicates that the patient is receiving active treatment or follow-up for this specific fracture after the initial encounter.

Apply this code when a patient presents for ongoing management of a hip fracture caused by a pathological condition (e.g., osteoporosis, tumor, metabolic bone disease) and the healing process is progressing slower than expected. Documentation should clearly state "pathological fracture," "hip," and "delayed healing" during a subsequent encounter.

• Ensure documentation specifies the underlying disease causing the pathological fracture.
• Distinguish from nonunion (M84.4-) or malunion (M84.3-) which have separate codes.
• Always sequence the underlying disease code first, followed by this fracture code.
