Other disorders of continuity of bone, unsp ulna and radius

This code signifies a disruption in the normal structure or integrity of the ulna and/or radius bones that doesn't fit into more specific categories like nonunion or malunion. It indicates an unspecified issue affecting the continuity of these forearm bones.

Use this code when documentation indicates a disorder of bone continuity in the ulna and radius, but the specific nature of the disorder (e.g., nonunion, malunion, stress fracture, etc.) is not clearly identified. This code is appropriate when the provider notes "other disorder of continuity" or similar vague terminology for the forearm bones.

• Avoid using this code if a more specific diagnosis for the bone continuity disorder (e.g., M84.3x for stress fracture, M84.2x for delayed union) is documented.
• Query the provider for clarification if the documentation is ambiguous regarding the specific type of bone continuity disorder.
• Ensure the documentation clearly specifies the ulna and/or radius as the affected bones; otherwise, an unspecified site code may be more appropriate.
