Pathological fracture, right toe(s), subs for fx w nonunion

This code signifies a fracture of the right toe(s) that occurred due to an underlying disease process, rather than trauma, and has failed to heal properly. The "nonunion" indicates that the bone fragments have not united after a sufficient healing period, and the "subsequent encounter" specifies that the patient is receiving follow-up care for this unhealed fracture.

Apply this code when a patient presents for ongoing treatment of a right toe pathological fracture that has been diagnosed as a nonunion. Documentation should clearly state the pathological nature of the fracture, its location in the right toe(s), and the current status as a nonunion requiring further management (e.g., surgical intervention for nonunion, casting for delayed union progressing to nonunion).

• Always sequence this code after the underlying pathological condition causing the fracture (e.g., osteoporosis, neoplasm).
• Ensure documentation explicitly states "nonunion" and the "pathological" nature of the fracture to differentiate from traumatic fractures or delayed unions.
• Verify the laterality (right toe) and the encounter type (subsequent encounter) are accurately reflected in the medical record.
