Osteitis deformans of right lower leg

This code signifies Paget's disease of bone specifically affecting the right lower leg. It describes a chronic disorder of localized bone remodeling, characterized by excessive bone resorption followed by disorganized and accelerated bone formation, leading to enlarged and weakened bones in the tibia or fibula of the right leg.

Use this code when documentation clearly indicates a diagnosis of Paget's disease (osteitis deformans) impacting the right lower extremity. Supporting documentation should specify the affected limb and confirm the diagnosis through imaging studies (e.g., X-rays, bone scans) and/or elevated alkaline phosphatase levels.

• Ensure laterality is explicitly documented as "right lower leg" to support this specific code.
• Do not confuse with other localized bone disorders or generalized metabolic bone diseases.
• Consider sequencing this code after any underlying cause or associated complications, if applicable.
