Oth disrd of bone density and structure, left shoulder

This code signifies a non-osteoporotic, non-osteomalacic, or non-Paget's disease abnormality in the density or structure of the bone specifically affecting the left shoulder. This could include conditions like fibrous dysplasia, osteogenesis imperfecta, or other rare metabolic bone disorders that manifest in the shoulder region. It indicates a structural or density issue that doesn't fit into more common categories of bone disease.

Use this code when documentation clearly identifies an "other specified" disorder of bone density or structure impacting the left shoulder, such as fibrous dysplasia of the humerus or scapula, or osteogenesis imperfecta affecting the left shoulder girdle. Supporting documentation should include diagnostic imaging (X-ray, MRI, CT) and physician notes detailing the specific bone disorder and its location.

• Ensure the documentation specifies "left shoulder" to justify laterality. If unspecified, an unspecified laterality code should be used.
• Distinguish this from osteoporosis (M80-M82) or osteomalacia (M83) as this code is for other specified disorders.
• Always look for a more specific code within the M85 category or other bone disorder categories if the condition is clearly defined (e.g., Paget's disease, osteogenesis imperfecta with specific type).
