Pathological fracture in oth disease, left humerus, init

This code signifies a fracture of the left humerus that occurred due to an underlying disease process, rather than significant trauma. It indicates that the patient is receiving initial treatment for this specific fracture. Such fractures often result from conditions that weaken bone structure, making them susceptible to breaking under normal stress.

Use this code when documentation clearly states a pathological fracture of the left humerus, and the patient is in the active treatment phase for the fracture. This typically applies to fractures caused by conditions like osteoporosis, metastatic cancer, or Paget's disease. Physician notes should explicitly link the fracture to an underlying disease and confirm it's the initial encounter.

• Always code the underlying disease causing the pathological fracture first, followed by this code.
• Ensure documentation specifies "left humerus" and "pathological fracture" to support this code.
• Verify the encounter type (initial, subsequent, sequela) to select the correct 7th character.
