Osteitis deformans of right hand

This code signifies Paget's disease affecting the bones of the right hand. It describes a chronic disorder of bone remodeling, characterized by excessive bone resorption followed by disorganized and accelerated bone formation, leading to enlarged and weakened bones. This specific code indicates the involvement of the right hand.

Use this code when documentation explicitly states a diagnosis of Paget's disease (osteitis deformans) localized to the right hand. Supporting documentation would include physician notes detailing diagnostic findings such as X-rays showing characteristic bone changes (e.g., bone enlargement, cortical thickening, trabecular coarsening) in the right hand, elevated alkaline phosphatase levels, and/or bone biopsy results confirming Paget's disease.

• Ensure the laterality (right hand) is clearly documented. If the left hand or bilateral involvement is present, a different code is required.
• Do not confuse with other forms of osteitis or osteoarthritis; this code is specific to Paget's disease.
• Code any associated pathological fractures of the right hand separately, if present, and sequence appropriately.
