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

This code signifies a partial dislocation of a metacarpal bone at its proximal end, meaning it has moved out of its normal alignment but the joint surfaces are still in partial contact. This injury affects the hand, but the specific metacarpal bone and the affected hand (left or right) are not specified.

Use this code when a patient presents with a newly diagnosed subluxation of a metacarpal bone in the hand, and the documentation does not specify which metacarpal or which hand. This is appropriate for the initial evaluation and treatment of the injury.

• Ensure documentation clearly states "subluxation" rather than a complete dislocation.
• Only use this code when the specific metacarpal and hand are not documented; otherwise, a more specific code should be chosen.
• The "A" suffix indicates an initial encounter for active treatment of the injury.
