Osteolysis, left shoulder

This code describes the pathological destruction or dissolution of bone tissue in the left shoulder. It indicates a progressive loss of bone mass, which can lead to structural weakness, pain, and impaired joint function. This condition is distinct from osteoporosis, as it specifically refers to localized bone resorption rather than generalized skeletal demineralization.

This code is appropriate for documenting cases of localized bone destruction affecting the left shoulder, as identified through imaging studies (e.g., X-ray, MRI, CT scan) and clinical assessment. It should be used when the physician's documentation clearly states "osteolysis of the left shoulder" or similar terminology indicating bone resorption in this specific anatomical site.

• Ensure laterality is accurately documented and coded; this code specifies the left shoulder.
• Distinguish osteolysis from other bone conditions like osteoporosis (M81.-) or osteomyelitis (M86.-), which involve different pathological processes.
• Look for documentation of the underlying cause of the osteolysis, if known, as an additional code may be required to fully describe the patient's condition.
