Path fx in oth disease, l ulna, subs for fx w routn heal

This code signifies a fracture of the left ulna that occurred due to an underlying disease process, rather than trauma. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, which is currently healing routinely without complications.

Apply this code when a patient presents for ongoing management of a left ulnar pathological fracture, and the medical record indicates normal progression of healing. Documentation should clearly state the fracture's pathological origin (e.g., due to osteoporosis, metastatic disease, or other systemic conditions) and that the encounter is for follow-up care with routine healing.

• Always code the underlying disease responsible for the pathological fracture first.
• Ensure the documentation specifies "routine healing" to differentiate from delayed healing, nonunion, or malunion.
• Verify laterality (left ulna) is clearly documented to avoid coding errors.
