Unsp fx upper end of l humerus, subs for fx w routn heal

This code signifies an unspecified fracture located in the upper portion of the left humerus, indicating that the precise anatomical site of the fracture (e.g., surgical neck, anatomical neck, greater tuberosity) was not documented. The "D" seventh character specifies that this is a subsequent encounter for the fracture, and the healing process is progressing routinely without complications.

This code is appropriate for follow-up visits where a patient is being monitored for a previously diagnosed, non-specific fracture of the upper left humerus that is healing as expected. It would be used after the initial treatment phase, during the period of routine follow-up and rehabilitation. This code would not be used for initial treatment or for encounters involving delayed healing or complications.

• Ensure documentation clearly states "left" humerus and specifies a subsequent encounter with routine healing.
• If the specific site of the fracture (e.g., surgical neck, anatomical neck) is documented, a more specific code from the S42.2- series should be used.
• Do not use this code if there are complications such as nonunion, malunion, or delayed healing; different seventh characters or codes would be required.
