Displ oblique fx shaft of r ulna, 7thP

This code signifies a situation where a patient has previously sustained an oblique fracture of the shaft of their right ulna, and during a follow-up encounter, the fracture is found to have healed incorrectly, resulting in a malunion. The fracture itself is closed, meaning there is no open wound communicating with the fracture site.

Use this code for subsequent encounters when a patient is being treated for complications arising from a right ulnar shaft fracture that has healed in an anatomically incorrect position. This typically involves ongoing management, assessment of function, or planning for corrective procedures related to the malunion.

• Ensure documentation clearly states "malunion" and specifies the right ulna and shaft location.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
• Verify the fracture was initially closed; if it was open, a different code series would be appropriate.
