Other disorders of continuity of bone, right humerus

This code signifies a non-union, malunion, or other disruption in the normal healing or structure of the right humerus, excluding typical fractures. It represents a pathological discontinuity of the bone that is not classified as a simple fracture or a stress fracture. This condition often results in pain, instability, and functional impairment of the upper arm.

Use this code when documentation specifies a disorder of bone continuity in the right humerus, such as a non-union of a previously treated fracture, a malunion causing significant deformity, or other specified pathological discontinuity not fitting a more specific fracture code. This code is appropriate when the physician explicitly diagnoses a "disorder of continuity" or similar terminology for the right humerus.

• Ensure the documentation clearly specifies "right humerus" to avoid laterality errors.
• Do not use this code for acute fractures; instead, refer to the S42 category for humerus fractures.
• Consider sequencing this code after a code for the underlying cause if known and documented (e.g., failed internal fixation).
