Nondisp fx of coronoid pro of l ulna, 7thR

This code signifies a previously treated fracture of the coronoid process on the left ulna that was initially an open fracture of type IIIA, IIIB, or IIIC, and has since healed improperly, resulting in malunion. The current encounter is for follow-up care or management of this malunion, not for the initial treatment of the fracture.

This code is appropriate for encounters where a patient is being seen for complications or ongoing management related to a malunited, nondisplaced coronoid process fracture of the left ulna, which was originally an open fracture (Gustilo-Anderson type IIIA, IIIB, or IIIC). This would include scenarios such as evaluating range of motion limitations, pain, or planning for corrective surgery due to the malunion.

• Ensure documentation clearly specifies "malunion" and that the initial fracture was an open type IIIA, IIIB, or IIIC.
• Verify the laterality (left ulna) and the specific anatomical site (coronoid process).
• This code is for a subsequent encounter, meaning the initial fracture treatment has already occurred.
