Osteitis deformans of right forearm

This code signifies Paget's disease affecting the bones of the right forearm. It represents a chronic bone disorder characterized by abnormal bone remodeling, leading to enlarged, misshapen, and weakened bones in this specific anatomical location.

Apply this code when documentation explicitly states a diagnosis of Paget's disease (osteitis deformans) impacting the right forearm. Supporting documentation should include physician notes detailing the diagnosis and the affected limb.

• Ensure laterality is clearly documented as "right forearm" to support this specific code.
• Do not use this code for Paget's disease affecting other anatomical sites; specific codes exist for those locations.
• Consider co-occurring conditions, such as pathological fractures, and code them additionally if present.
