Displ oblique fx shaft of r ulna, 7thM

This code describes a situation where a patient has a non-healing oblique fracture in the shaft of their right ulna, which was initially an open fracture (Type I or II). The fracture fragments are no longer in their normal anatomical alignment.

This code is used for follow-up encounters when a patient is receiving ongoing treatment for a previously diagnosed open oblique ulnar shaft fracture that has failed to unite. It specifically applies when the fracture is displaced and was initially classified as an open fracture type I or II.

• Ensure documentation clearly specifies "nonunion" and the "displaced" nature of the fracture.
• Verify the initial open fracture type (I or II) is documented for accurate coding.
• Confirm this is a subsequent encounter, not the initial treatment encounter.
