Displaced Rolando's fracture, r hand, subs for fx w nonunion

This code signifies a fracture of the Rolando's process, which is the base of the first metacarpal bone in the right hand, that is displaced. The "subsequent encounter" indicates the patient is receiving routine care for the fracture during the healing phase, and "nonunion" specifies that the bone is failing to heal properly.

Use this code for follow-up visits where a patient with a previously diagnosed, displaced Rolando's fracture of the right hand is being treated for a confirmed nonunion. This applies to ongoing management, such as cast changes, physical therapy, or preparation for surgical intervention to address the nonunion.

• Ensure documentation clearly specifies "displaced" and "right hand" for the Rolando's fracture.
• Verify the encounter is for subsequent care of the fracture and that nonunion has been diagnosed.
• Do not use for initial fracture diagnosis or for malunion, which is a different complication.
