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

This code signifies a complete displacement of the metacarpal bone from its normal articulation at the wrist (carpometacarpal joint) in the left hand. It specifically refers to the initial presentation of this injury.

This code is appropriate for documenting a patient's first visit for a left-sided metacarpal dislocation at the proximal end, often resulting from trauma such as a fall or direct impact. It should be used when the patient is receiving active treatment for the injury.

• Ensure laterality (left hand) is accurately documented in the medical record.
• Verify that the dislocation is at the proximal end of the metacarpal, not the distal end or a fracture.
• Confirm this is the initial encounter for active treatment; subsequent encounters will require a different seventh character.
