Path fx in oth disease, l humerus, subs for fx w routn heal

This code signifies a fracture of the left humerus that occurred due to an underlying disease process, rather than trauma. The patient is currently in a phase of routine healing following initial treatment for this pathological fracture.

Apply this code for follow-up encounters where a patient is receiving ongoing care for a left humeral pathological fracture and the healing is progressing as expected. Documentation should clearly state "pathological fracture," specify the left humerus, and indicate a "subsequent encounter" with "routine healing."

• Ensure documentation explicitly states the fracture is "pathological" and specifies the left humerus.
• Verify the encounter is for follow-up care with routine healing, not initial treatment or delayed/nonunion.
• Always code the underlying disease causing the pathological fracture first, if known and actively treated or monitored.
