Subluxation of oth carpometacarpal joint of unsp hand, init

This code signifies a partial dislocation of a carpometacarpal joint, excluding the thumb, in an unspecified hand. The joint surfaces are no longer perfectly aligned but remain in contact. This injury typically results in pain, swelling, and limited range of motion in the affected wrist and hand.

Apply this code for initial encounters involving a patient presenting with a subluxation of any carpometacarpal joint other than the first (thumb) carpometacarpal joint. This would include injuries to the joints connecting the metacarpals to the trapezium, trapezoid, capitate, or hamate bones.

• Ensure documentation specifies "subluxation" rather than a complete "dislocation" for accurate coding.
• Confirm the injury involves a carpometacarpal joint other than the thumb.
• The "A" in the seventh character indicates an initial encounter for this injury.
