Pathological fracture, unsp hand, subs for fx w delay heal

This code signifies a fracture in an unspecified hand that occurred due to a pre-existing disease or condition, rather than trauma. The patient is currently receiving routine care during the healing phase, but the healing process is taking longer than expected.

Apply this code when documentation indicates a pathological fracture of the hand, without specifying left or right, and the patient is being seen for follow-up care due to delayed healing. The encounter should be for ongoing management of the fracture, not the initial treatment or sequelae.

• Requires documentation of a pathological cause for the fracture and explicit mention of delayed healing.
• Distinguish from nonunion (M84.443K) or malunion (M84.443P) which represent different healing complications.
• Always sequence after the underlying disease causing the pathological fracture, if applicable and still active.
