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

This code signifies a previously treated, non-displaced fracture of the olecranon process that extends into the elbow joint, affecting an unspecified ulna. The fracture was initially an open fracture of severe type (IIIA, IIIB, or IIIC), and the current encounter addresses a complication where the bone fragments have healed in an incorrect anatomical position (malunion).

Use this code for follow-up encounters where a patient is being managed for a malunion of a non-displaced olecranon fracture with intraarticular extension, which was originally a severe open fracture. This would apply to situations like surgical correction of the malunion, cast changes, or ongoing physical therapy related to the malunion.

• Ensure documentation clearly specifies "malunion" as the reason for the subsequent encounter.
• Verify the original fracture was an open fracture type IIIA, IIIB, or IIIC.
• Confirm the fracture was non-displaced and involved intraarticular extension of the olecranon.
