Unsp fx shaft of humer, right arm, subs for fx w delay heal

This code signifies an unspecific break in the main part (shaft) of the right upper arm bone (humerus) that is not healing as quickly as expected. The patient has been seen previously for this fracture, and the current encounter focuses on its ongoing management due to delayed union.

Apply this code when documentation indicates a right humeral shaft fracture, without further specification of the fracture type (e.g., transverse, oblique), that is in a subsequent phase of care and exhibiting delayed healing. This would be appropriate for follow-up appointments where the physician is monitoring the slow progress of bone repair.

• Ensure the documentation explicitly states "delayed healing" or a similar term indicating a slower-than-expected healing process.
• Verify the fracture location is the shaft of the humerus and laterality is the right arm.
• Confirm this is not the initial encounter for the fracture; look for "subsequent encounter" in the clinical notes.
