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

This code signifies a fracture of the right ankle that occurred due to an underlying disease process, rather than trauma. The patient is currently in a phase of treatment where the fracture is not healing at the expected rate.

Apply this code for follow-up encounters where a patient with a right ankle pathological fracture is experiencing delayed union. Documentation should clearly state the pathological nature of the fracture, the anatomical site (right ankle), and evidence of delayed healing.

• Requires a secondary code to identify the underlying disease causing the pathological fracture.
• Ensure documentation specifies "delayed healing" for the 7th character 'G'.
• Distinguish from nonunion (7th character 'K') or routine healing (7th character 'D').
