Nondisp fx of coronoid pro of unsp ulna, 7thR

This code signifies a previously treated fracture of the coronoid process of the ulna, which was initially an open fracture of type IIIA, IIIB, or IIIC, and has now healed in an unsatisfactory position (malunion). The fracture itself was nondisplaced, meaning the bone fragments remained in their anatomical alignment at the time of the initial injury. This code is used during a subsequent encounter for ongoing management of this specific complication.

Use this code when documenting follow-up care for a patient who sustained an open coronoid process fracture (types IIIA, IIIB, or IIIC) that has subsequently developed malunion. This applies to situations where the initial fracture was nondisplaced. This code is appropriate for encounters addressing the malunion, such as evaluation for corrective surgery or ongoing pain management related to the improper healing.

• Ensure the documentation clearly specifies an open fracture (type IIIA, IIIB, or IIIC) and the presence of malunion.
• Verify that the initial fracture was nondisplaced; displaced fractures would require a different code.
• This code is for subsequent encounters, not the initial treatment of the fracture.
