Disp fx of coronoid pro of unsp ulna, 7thP

This code signifies a fracture of the coronoid process, a small projection on the ulna bone in the forearm, that is no longer in its proper anatomical alignment. The injury is to an unspecified ulna (left or right) and is being treated in a subsequent encounter, indicating ongoing care for a closed fracture that has healed incorrectly, resulting in a malunion.

Apply this code when documenting follow-up care for a patient who previously sustained a closed, displaced coronoid process fracture of the ulna, and imaging or clinical assessment confirms that the bone has healed in an unsatisfactory position. This includes situations where the patient is undergoing rehabilitation, monitoring for complications, or considering corrective surgery for the malunion.

• Ensure documentation clearly specifies "subsequent encounter" and "malunion" for a closed fracture.
• Do not use this code for initial treatment or for open fractures.
• If the laterality (left or right ulna) is specified in the documentation, a more specific code should be chosen.
