Nondisp fx of base of fourth MC bone, left hand, init

This code signifies a break in the base of the fourth metacarpal bone in the left hand, where the bone fragments remain in their normal anatomical alignment. It indicates that the skin over the fracture site is intact, and this is the first time the patient is being treated for this specific injury.

Apply this code for patients presenting with a newly diagnosed, non-displaced fracture at the proximal end of the fourth metacarpal of the left hand. This is appropriate for initial treatment encounters, such as emergency department visits or initial orthopedic consultations.

• Ensure documentation specifies "nondisplaced" and "closed" for accurate code assignment.
• Verify the laterality is "left hand" and the specific bone is the "fourth metacarpal."
• Confirm this is the "initial encounter" for treatment of this fracture; subsequent encounters will use different seventh characters.
