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

This code signifies a fracture of the base of the thumb metacarpal (first metacarpal) that has not shifted from its normal anatomical position. Specifically, it indicates that the patient is presenting for follow-up care of this fracture, and there is evidence that the bone fragments are failing to heal properly.

Apply this code when a patient with a previously diagnosed nondisplaced Rolando's fracture of the right hand is seen for ongoing management due to a confirmed nonunion. This typically occurs during follow-up appointments after initial treatment, where imaging or clinical assessment reveals a lack of bone healing.

• Ensure documentation clearly specifies "nondisplaced" and "Rolando's fracture" of the right hand.
• The "K" seventh character indicates a subsequent encounter for a fracture with nonunion, so verify that the patient is receiving active treatment for the nonunion.
• Do not use this code for initial encounters or for fractures that are healing normally.
