Osteitis deformans without mention of bone tumor

This code represents Paget's disease of bone, a chronic disorder characterized by abnormal bone remodeling. It involves excessive bone resorption followed by disorganized and accelerated bone formation, leading to enlarged and weakened bones. This specific code is used when there is no associated bone tumor.

Use this code for patients diagnosed with Paget's disease of bone based on clinical findings, imaging studies (e.g., X-rays, bone scans), and elevated biochemical markers (e.g., alkaline phosphatase). It is appropriate when the documentation explicitly states or implies the absence of a bone tumor.

• Ensure documentation clearly distinguishes between Paget's disease and other bone disorders, such as osteomyelitis or fibrous dysplasia.
• Do not use this code if a bone tumor, benign or malignant, is present; instead, refer to codes that specify Paget's disease with a bone tumor.
• Confirm that the provider's notes support the "without mention of bone tumor" aspect, as this is a key differentiator for this specific code.
