Nondisp oblique fx shaft of unsp ulna, 7thQ

This code describes a follow-up encounter for a patient with a previously treated oblique fracture of the shaft of the ulna, where the fracture was not displaced at the time of the initial injury. The initial fracture was an open fracture classified as Type I or II, and the current encounter addresses a malunion, meaning the bone has healed in an incorrect anatomical position.

Use this code for subsequent visits when a patient is being managed for complications arising from an open oblique ulnar shaft fracture that has healed with malunion. This applies to situations such as ongoing physical therapy, assessment for corrective surgery, or monitoring of functional limitations due to the malunion.

• Ensure documentation clearly specifies "malunion" as the reason for the subsequent encounter.
• Verify the original fracture was an open Type I or II and involved the shaft of the ulna.
• This code is for the unspecified ulna; if laterality is known, a more specific code should be used.
