Dislocation of oth carpometacarpal joint of unsp hand, init

This code signifies the displacement of a carpometacarpal joint other than the thumb, within the hand, where the specific hand (left or right) is not documented. This injury involves the separation of the joint surfaces between a carpal bone and a metacarpal bone.

Apply this code for initial encounters with patients presenting with a newly diagnosed dislocation of any carpometacarpal joint except the first (thumb CMC), when the laterality of the injury is not specified in the medical record. This would include dislocations of the second, third, fourth, or fifth carpometacarpal joints.

• Ensure documentation clearly states "dislocation" and specifies a carpometacarpal joint other than the thumb.
• Only use this code when the medical record does not specify whether the injury is to the left or right hand.
• The "A" seventh character indicates an initial encounter for active treatment of the dislocation.
