Nondisp fx of base of 2nd MC bone, r hand, 7thK

This code signifies a fracture at the base of the second metacarpal bone in the right hand that has not displaced, meaning the bone fragments remain in their anatomical alignment. The "subsequent encounter for fracture with nonunion" indicates that the fracture has failed to heal properly after an initial treatment period, and the patient is receiving ongoing care for this complication.

This code is appropriate when a patient presents for follow-up care of a previously diagnosed, nondisplaced fracture at the base of their right second metacarpal, and imaging or clinical assessment confirms that the fracture has not united. This would include scenarios where surgical intervention for nonunion is being planned or performed, or conservative management for the nonunion is ongoing.

• Ensure documentation clearly specifies "nondisplaced" and the "base" of the second metacarpal.
• Verify that the encounter is for ongoing treatment of the nonunion, not the initial injury or routine healing.
• Always confirm laterality (right hand) is explicitly stated in the medical record.
