Other disorders of continuity of bone, right ulna

This code signifies a non-union, malunion, or other specified disruption in the normal structure and integrity of the right ulna bone, excluding typical fractures or stress fractures. It encompasses conditions where the bone's continuity is compromised due to issues other than acute traumatic breaks.

Apply this code when documentation specifies a disorder of bone continuity of the right ulna, such as a non-union following a previous fracture, a malunion requiring intervention, or other specified structural defects. This code is appropriate when the physician explicitly diagnoses a "disorder of continuity" rather than an acute fracture or sequela of a fracture.

• Ensure the documentation clearly specifies "right ulna" and a "disorder of continuity" distinct from a fracture.
• Do not use for acute fractures; refer to the S52 category for those.
• Consider sequencing this code after a code for the underlying cause if known and still active.
