Nondisp fx of olecran pro w intartic extn unsp ulna, 7thM

This code describes a fracture of the olecranon process of the ulna that extends into the elbow joint, but the bone fragments are still in their normal anatomical position. The fracture is an open type I or II, meaning there is a wound communicating with the fracture site, and it has failed to heal properly (nonunion) during a subsequent treatment encounter.

Use this code for follow-up encounters where a patient is being treated for a previously diagnosed nondisplaced, intraarticular olecranon fracture that was initially an open type I or II, and the fracture has not united. This applies when the patient is still receiving care for the nonunion.

• Ensure documentation specifies "nondisplaced" and "intraarticular extension" of the olecranon fracture.
• Verify the original injury was an "open fracture type I or II" and that the current encounter addresses "nonunion."
• The "M" in the seventh character indicates a subsequent encounter for nonunion; do not use for initial treatment or routine healing.
