Unsp disp fx of surg nk of r humer, subs for fx w delay heal

This code signifies a fracture of the surgical neck of the right humerus where the bone fragments are not properly aligned, and the specific type of fracture is not documented. The patient is in a later stage of care for this injury, and the fracture is not healing as expected within the typical timeframe.

Use this code when a patient presents for follow-up care of a right humeral surgical neck fracture that was initially displaced, and the provider notes delayed healing. This applies to situations where the specific fracture pattern (e.g., comminuted, segmental) was not detailed in the initial diagnosis or subsequent documentation.

• Ensure documentation clearly states "delayed healing" for the subsequent encounter.
• Verify laterality (right humerus) and the specific anatomical site (surgical neck).
• If the displacement type (e.g., angulated, rotated) is specified, a more precise code within the S42.21- category may be appropriate.
