Displ oblique fx shaft of humer, unsp arm, 7thK

This code signifies a follow-up encounter for a patient who sustained an oblique fracture in the shaft of their humerus, where the bone fragments are no longer in proper alignment. Crucially, this specific encounter addresses a situation where the fracture has failed to heal adequately, leading to a nonunion. The affected arm is not specified.

Apply this code when documenting subsequent care for a humerus shaft fracture that has been diagnosed with nonunion, and the initial injury was an oblique fracture with displacement. This would be appropriate for office visits, hospital admissions, or surgical encounters focused on managing the nonunion of this specific fracture type.

• Ensure documentation clearly states "nonunion" to justify the 7th character 'K'.
• Verify the fracture type is "oblique" and located in the "shaft of humerus" with "displacement."
• This code is for subsequent encounters; an initial encounter would use a different 7th character.
