Stress fracture, right foot, subs for fx w nonunion

This code signifies a stress fracture located in the right foot that has failed to heal properly, indicating a nonunion. It specifically applies to a patient encounter occurring after the initial treatment of the fracture, where the nonunion is being addressed.

Use this code for follow-up encounters where a previously diagnosed stress fracture of the right foot is documented as having a nonunion. Documentation must clearly state "nonunion" and specify the right foot as the affected site, with the encounter being for ongoing management of this complication.

• Ensure documentation explicitly states "nonunion" and not just delayed healing or malunion.
• Verify the laterality is correctly identified as the "right foot."
• This "K" seventh character indicates a subsequent encounter for a fracture with nonunion; do not confuse with "D" (subsequent for routine healing) or "P" (subsequent for malunion).
