Sublux of MC (bone), proximal end of left hand, sequela

This code signifies a chronic or late-effect subluxation, or partial dislocation, of the proximal end of a metacarpal bone in the left hand. This condition implies that the joint surfaces are no longer in proper alignment, but remain in partial contact, and the injury has long-term consequences or manifestations.

Apply this code when documenting a patient presenting with a persistent or residual subluxation of the left metacarpal's proximal end, where the initial injury occurred in the past and is no longer in the acute phase. This is appropriate for conditions like chronic pain, instability, or deformity resulting from a prior subluxation.

• Always ensure documentation clearly states "sequela" or indicates a chronic/late effect of the subluxation.
• Verify the specific metacarpal bone is not further specified, as this code is for a general metacarpal subluxation.
• Confirm the laterality is explicitly documented as "left hand."
