Path fx in oth disease, r humerus, subs for fx w delay heal

This code signifies a fracture of the right humerus that occurred due to an underlying disease process, rather than trauma. The patient is currently receiving follow-up care for this fracture, and the healing process is progressing slower than expected. This indicates a complication in the fracture recovery.

Apply this code for patients presenting for ongoing management of a right humeral fracture where the fracture was caused by a pathological condition (e.g., osteoporosis, metastatic bone disease, Paget's disease). Documentation must clearly state "delayed healing" and specify the right humerus as the fracture site. This code is appropriate for subsequent encounters after the initial treatment.

• Always sequence the underlying pathological condition causing the fracture first.
• Ensure documentation explicitly states "delayed healing" for the subsequent encounter.
• Distinguish from nonunion (M84.3-) or malunion (M84.4-) which represent different healing complications.
