Fracture of one rib, right side, subs for fx w delay heal

This code signifies a patient presenting for follow-up care of a previously diagnosed fracture of a single rib on the right side. The key clinical finding is that the fracture is not healing at the expected rate, indicating delayed union.

Apply this code when a patient returns for an office visit, imaging, or other treatment related to a right-sided rib fracture that has been identified as having delayed healing. This would typically be used after the initial treatment phase and when the physician documents concerns about the healing progress.

• Ensure documentation clearly specifies "delayed healing" for the right rib fracture.
• Verify that only one rib is fractured; if multiple ribs are involved, a different code is required.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
