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

This code describes a follow-up encounter for a fracture of the base of the thumb metacarpal (Rolando's fracture) in the left hand. The fracture was initially nondisplaced, but has subsequently healed in an imperfect alignment, known as a malunion. This indicates a complication of the healing process.

Use this code when documenting a patient visit for ongoing management or evaluation of a previously treated nondisplaced Rolando's fracture of the left hand that has resulted in a malunion. This would apply to scenarios where the patient is experiencing symptoms related to the malunion, or when the malunion is identified during a follow-up imaging study.

• Ensure documentation clearly specifies "left hand" and "nondisplaced" for the initial fracture.
• Verify that "malunion" is explicitly documented as the current healing status or complication.
• This code is for a subsequent encounter, so an initial encounter code would have been used for the acute injury.
