Nondisp fx of base of 4th MC bone, l hand, init for opn fx

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. This specific instance indicates that the fracture is open, meaning there is a break in the skin overlying the fracture site, and it is the initial treatment encounter for this injury.

Apply this code when documenting the initial treatment for an open fracture of the base of the fourth metacarpal bone in the left hand that is confirmed to be nondisplaced. This would be appropriate for a patient presenting to the emergency department or clinic immediately following such an injury.

• Ensure documentation clearly specifies "nondisplaced" and "open fracture" for accurate code assignment.
• Verify laterality (left hand) and the specific metacarpal bone (fourth) are explicitly stated in the clinical record.
• Confirm this is the initial encounter for treatment; subsequent encounters will require a different seventh character.
