Disp fx of base of fifth metacarpal bone, left hand, 7thB

This diagnosis code indicates a break in the base of the fifth metacarpal bone in the left hand, where the bone fragments are no longer in their normal alignment. It specifies that the fracture is an open fracture, meaning there is a break in the skin communicating with the fracture site. This code is used for the initial treatment of such an injury.

This code is appropriate for documenting the initial encounter for a patient presenting with a displaced fracture at the base of the left fifth metacarpal, where the fracture has broken through the skin. This typically occurs due to direct trauma to the hand, such as a punch or fall. It should be used when the patient is receiving active treatment for the fracture.

• Confirm laterality (left hand) and the specific bone (fifth metacarpal base) are accurately documented.
• Verify the fracture is explicitly described as "displaced" and "open" in the medical record.
• Ensure this is the patient's initial encounter for active treatment of this specific fracture.
