Disloc of metacarpal (bone), proximal end of unsp hand, init

This code signifies a traumatic displacement of the proximal end of a metacarpal bone from its normal articulation. This injury involves the joint closest to the wrist, affecting one of the long bones of the hand, but the specific hand (left or right) is not documented.

Use this code for a patient presenting with an acute, newly diagnosed dislocation of the metacarpal base, where the laterality of the hand is not specified in the medical record. This typically occurs following direct trauma or a fall onto an outstretched hand.

• Ensure documentation specifies "proximal end" or "base" of the metacarpal to differentiate from other metacarpal dislocations.
• Only use the "A" seventh character for the initial treatment of the injury.
• If the laterality (left or right hand) is documented, a more specific code should be selected.
