Nondisp Rolando's fracture, r hand, subs for fx w malunion

This code signifies a Rolando's fracture of the right thumb metacarpal base, which is a comminuted intra-articular fracture. "Nondisplaced" indicates the bone fragments are still in their anatomical position. "Subsequent encounter for fracture with malunion" specifies that the patient is receiving ongoing care for this fracture, and it has healed in a misaligned or deformed position.

Use this code when documenting follow-up care for a patient with a previously diagnosed nondisplaced Rolando's fracture of the right hand, and clinical or radiological evidence confirms that the fracture has healed with malunion. This applies to encounters where treatment for the malunion, such as corrective osteotomy or physical therapy, is being provided or planned.

• Ensure documentation clearly states "nondisplaced" and specifies the "right hand."
• Confirm the encounter is for follow-up care of a fracture that has healed with malunion, not an initial injury or routine follow-up without complications.
• Distinguish from nonunion (S62.224N) or routine healing (S62.224D, S62.224G, S62.224K, S62.224P).
