Nondisp fx of base of 4th MC bone, l hand, 7thD

This code indicates a fracture of the base of the fourth metacarpal bone in the left hand that has not shifted out of alignment. The patient is in a follow-up phase of treatment, and the bone is healing as expected without complications.

This code is appropriate for documenting subsequent visits for a patient with a previously diagnosed, non-displaced fracture of the left fourth metacarpal base. It applies when the physician assesses the fracture and confirms routine healing, such as during cast changes, follow-up X-rays showing callus formation, or physical therapy evaluations.

• Ensure documentation specifies "nondisplaced" and "base of fourth metacarpal" for the left hand.
• Confirm the encounter is for follow-up care with routine healing, not initial treatment or delayed/nonunion.
• Always check for laterality (left vs. right) and the specific metacarpal bone involved.
