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

This code signifies a partial dislocation of the proximal end of a metacarpal bone in the left hand. It indicates that the joint surfaces are no longer in full apposition but remain in contact, without complete separation. This injury typically involves ligamentous stretching or tearing.

Apply this code for patients presenting with a documented subluxation of a left-hand metacarpal, specifically at its proximal end. This is appropriate for initial encounters where the patient is actively receiving treatment for the acute injury.

• Ensure documentation specifies "subluxation" and not a complete "dislocation" (S63.05-).
• Verify the laterality is "left" and the specific metacarpal bone (e.g., first, second, etc.) is identified if possible, though this code is general for any metacarpal.
• Confirm this is the "initial encounter" for the injury. Subsequent care would use the appropriate S63.062D or S63.062S.
