Nondisp fx of nk of 1st MC bone, l hand, 7thK

This code signifies a fracture of the first metacarpal neck in the left hand that has not shifted out of alignment. The key aspect is that the bone is failing to heal properly, and this encounter is for ongoing management of that nonunion.

Apply this code when documenting follow-up care for a patient with a previously diagnosed, nondisplaced fracture of the left first metacarpal neck where the fracture fragments have not united. This includes situations where the patient is undergoing further treatment, such as bone stimulation or surgical intervention, for the nonunion.

• Ensure documentation clearly states "nonunion" for the fracture.
• Verify the fracture is specifically of the "neck" of the "first metacarpal" and on the "left hand."
• Confirm this is a "subsequent encounter" for the fracture, not the initial treatment.
