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

This code describes a previously treated fracture of the olecranon process of an unspecified ulna that was initially an open fracture (Type IIIA, IIIB, or IIIC) and has subsequently healed in a misaligned position (malunion). The original fracture did not involve the joint surface and was not displaced.

Use this code for follow-up encounters where a patient is being treated for complications arising from a malunited, nondisplaced olecranon fracture that was initially an open fracture of a severe type. This is appropriate when the malunion is the primary focus of the current encounter, such as for evaluation or planning corrective surgery.

• Ensure documentation clearly specifies "malunion" as the complication and confirms the original fracture was an open Type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters; do not use for the initial treatment of the fracture.
• Verify the fracture was nondisplaced and did not have intraarticular extension.
