Disp fx of coronoid pro of r ulna, init for opn fx type I/2

This diagnosis describes a break in the coronoid process, a small bony projection on the ulna (forearm bone), which has shifted out of its normal alignment. The fracture is open, meaning the bone has broken through the skin, and is classified as either Type I or Type II based on the severity of the soft tissue damage. This code is used for the initial treatment of such an injury.

This code is appropriate for documenting the initial encounter for a patient presenting with an open, displaced fracture of the coronoid process of the right ulna. This would typically be seen in emergency department visits or initial orthopedic consultations following trauma where the skin integrity has been compromised.

• Ensure documentation clearly specifies "displaced" and "open fracture type I or II" for the right ulna's coronoid process.
• Verify this is the patient's initial encounter for this specific injury; subsequent care would use a different encounter character.
• Always review operative reports and physician notes for details on the fracture type (open vs. closed, displacement) and laterality.
