Disp fx of base of second MC bone, r hand, init for opn fx

This diagnosis describes a break in the base of the second metacarpal bone in the right hand, where the bone fragments are no longer in their normal anatomical alignment. It specifically indicates an open fracture, meaning there is a break in the skin overlying the fracture site, exposing the bone to the outside environment. This type of injury often results from direct trauma to the hand.

This code is appropriate for documenting the initial treatment of a patient presenting with a newly diagnosed, displaced, open fracture at the base of the right second metacarpal. It would be used when the patient is first seen for this specific injury, regardless of whether surgical or non-surgical management is initiated.

• Always confirm laterality (right vs. left hand) and the specific metacarpal involved.
• Distinguish between displaced and nondisplaced fractures, and open versus closed fractures, as these significantly impact code selection.
• Ensure the "initial encounter" seventh character is used only for the first time the patient is seen for active treatment of the fracture.
