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

This code signifies a break in the main part (shaft) of the fourth metacarpal bone in the left hand, where the bone fragments remain in their normal anatomical alignment. The fracture is classified as open, meaning there is a break in the skin overlying the fracture site, exposing the bone to the external environment. This code is used for the initial treatment of such an injury.

Apply this code when documenting the first encounter for a patient presenting with a left fourth metacarpal shaft fracture that is not displaced and involves an open wound. This includes initial evaluation, surgical repair, or casting/splinting for the open fracture. It is appropriate for emergency department visits or initial orthopedic consultations for this specific injury.

• Ensure documentation clearly specifies "left hand" and "fourth metacarpal."
• Verify the fracture is explicitly described as "nondisplaced" and "open."
• Confirm this is the patient's initial encounter for treatment of this specific fracture.
