Pathological fracture in oth disease, right humerus, init

This code signifies a fracture of the right humerus that occurred due to an underlying disease process, rather than significant trauma. It indicates that the bone was weakened by a condition, making it susceptible to fracture from minimal or no force. This specific code is for the initial treatment phase of such a fracture.

Use this code when documentation clearly states a pathological fracture of the right humerus, often in the context of osteoporosis, metastatic bone disease, or other conditions that compromise bone integrity. The "A" seventh character is appropriate for the initial encounter where the patient is receiving active treatment for the fracture.

• Ensure the documentation explicitly states "pathological fracture" and specifies the right humerus.
• Do not use this code for traumatic fractures, even if the patient has an underlying bone disease; those require codes from the S42 series.
• Always sequence the underlying disease causing the pathological fracture (e.g., M80.08XA for age-related osteoporosis with pathological fracture, other site) before this code.
