Displ Rolando's fracture, left hand, subs for fx w nonunion

This code signifies a fracture of the base of the left thumb's first metacarpal bone, specifically a comminuted intra-articular fracture (Rolando's fracture), that is currently displaced. The "subsequent encounter" indicates the patient is receiving routine care during the healing phase, but the "nonunion" specifies that the bone fragments have failed to heal properly after a typical healing period.

Use this code for follow-up visits where a patient with a previously diagnosed and treated displaced Rolando's fracture of the left hand is being managed for a confirmed nonunion. This applies when the physician is assessing the nonunion, planning further intervention, or providing ongoing care for the unhealed fracture.

• Ensure documentation clearly states "left hand" and "nonunion" for this specific fracture type.
• Verify that the encounter is for follow-up care, not the initial treatment of the fracture.
• Confirm the fracture is explicitly identified as a Rolando's fracture and is displaced.
