Major osseous defect, left shoulder region

This code signifies a significant structural loss of bone tissue in the left shoulder area. This defect can result from trauma, infection, tumor resection, or congenital anomalies, leading to compromised skeletal integrity and function.

Apply this code when documentation clearly indicates a substantial bone defect in the left shoulder, such as after a severe fracture with bone loss, tumor excision requiring significant bone removal, or osteomyelitis leading to bone destruction. Supporting documentation should specify the "major" nature of the defect and its location.

• Ensure the documentation specifies "major" osseous defect and laterality (left shoulder).
• Do not use for minor bone irregularities or non-osseous defects.
• Consider sequencing this code after the underlying cause of the defect, if applicable (e.g., pathological fracture, osteomyelitis).
