Nondisp fx of olecran pro w intartic extn l ulna, 7thK

This code describes a specific type of elbow injury involving a nondisplaced fracture of the olecranon process of the left ulna, where the fracture line extends into the joint space. Importantly, this code is used during a subsequent encounter for a closed fracture that has failed to heal properly, resulting in a nonunion.

This code is appropriate when a patient presents for follow-up care of a previously diagnosed closed olecranon fracture of the left ulna, and imaging or clinical assessment confirms that the fracture has not united. It specifically applies to cases where the fracture was initially nondisplaced and involved the joint. This code would be used for ongoing management of the nonunion, such as surgical planning or continued conservative treatment.

• Ensure documentation clearly specifies "nondisplaced" and "intraarticular extension" for accurate code assignment.
• Verify the encounter is "subsequent" and the fracture is "closed" with evidence of "nonunion."
• Always review the patient's medical record for laterality (left vs. right) and the specific bone involved (ulna).
