Oth disrd of bone density and structure, multiple sites

This code signifies a bone density or structural abnormality that is not osteoporosis or osteomalacia, affects multiple skeletal sites, and is not classified elsewhere. It encompasses various rare or atypical bone disorders impacting the integrity and strength of bone tissue across the body.

Apply this code when documentation specifies a non-osteoporotic, non-osteomalacic bone density or structural disorder affecting more than one bone, and a more specific code is unavailable. Examples include certain genetic bone diseases, metabolic bone disorders, or other systemic conditions manifesting with diffuse bone abnormalities. Documentation should clearly identify the specific disorder and its multi-site involvement.

• Ensure the documentation explicitly states "multiple sites" or lists several affected bones to support this code.
• Do not use for localized bone density issues; those require more specific site-based codes.
• Always search for a more specific code first if the underlying condition is clearly identified (e.g., Paget's disease of bone has its own codes).
