Pathological fracture, right foot, sequela

This code signifies a pathological fracture of the right foot that has resulted in a long-term complication or condition. A pathological fracture occurs due to a disease process weakening the bone, rather than from trauma. The "sequela" indicates that the fracture itself is no longer acute, but its lasting effects are being addressed.

Apply this code when a patient presents with a chronic issue directly attributable to a previously sustained pathological fracture of the right foot. Documentation should clearly state the pathological nature of the original fracture and describe the current sequela being treated, such as malunion, nonunion, chronic pain, or functional impairment. This code is appropriate for follow-up care related to the long-term consequences of the fracture.

• Always sequence this code after the code for the underlying condition that caused the pathological fracture (e.g., osteoporosis, neoplasm).
• Ensure documentation specifies "right foot" and confirms the fracture was pathological, not traumatic.
• Do not use for acute pathological fractures; those are coded with the appropriate M84.4- code without the "S" seventh character.
