Disp fx of olecran pro w intartic extn unsp ulna, 7thR

This code describes a fracture of the olecranon (the bony prominence of the elbow) that extends into the elbow joint itself, where the broken bone fragments are no longer in their normal alignment. This specific code is used when the patient is receiving follow-up care for a severe open fracture (where the bone broke through the skin) that has not healed correctly, resulting in malunion.

Use this code for patients presenting for ongoing treatment of a previously sustained, severe open olecranon fracture with intraarticular extension that has healed in an anatomically incorrect position. This applies to subsequent encounters for complications related to the initial injury, such as pain, limited range of motion, or functional impairment due to the malunion.

• Ensure documentation clearly states "malunion" and specifies the "subsequent encounter" for an open fracture type IIIA, IIIB, or IIIC.
• Verify the fracture is explicitly described as "displaced" and having "intraarticular extension" of the olecranon process.
• Confirm the laterality of the ulna is unspecified in the clinical notes to align with this code's specificity.
