Osteitis deformans of other bones

This code signifies Paget's disease affecting bones other than the skull or vertebrae. It describes a chronic disorder of abnormal bone remodeling, leading to enlarged, misshapen, and weakened bones in various skeletal sites. This condition can result in bone pain, fractures, and deformities.

Apply this code when documentation specifies Paget's disease impacting bones such as the pelvis, femur, tibia, humerus, or any other bone not explicitly identified as skull or vertebral involvement. Supporting documentation should include diagnostic imaging (X-rays, bone scans) and clinical findings consistent with osteitis deformans in these non-excluded sites.

• Always review documentation to confirm the specific bone(s) affected to differentiate from skull (M88.0) or vertebral (M88.1) involvement.
• Code any associated pathological fractures separately, linking them to the underlying Paget's disease.
• Do not use this code if the documentation clearly indicates Paget's disease of the skull or vertebrae; use the more specific codes provided in the Excludes2 notes.
