Subluxation of oth carpometacarpal joint of left hand, init

This diagnosis code signifies a partial dislocation of a carpometacarpal joint in the left hand, excluding the thumb carpometacarpal joint. This means the bones forming the joint are no longer perfectly aligned but still maintain some contact. This injury typically results in pain, swelling, and limited range of motion in the affected area.

This code is appropriate for documenting the initial treatment of a patient presenting with a subluxation of any carpometacarpal joint in the left hand, except for the first carpometacarpal (thumb) joint. It should be used when the patient is receiving active treatment for the injury.

• Ensure the documentation specifies "left hand" and identifies the affected carpometacarpal joint (e.g., index, middle, ring, or small finger).
• Verify that the encounter is indeed the "initial encounter" for this specific injury; subsequent care would use a different seventh character.
• Distinguish this from a complete dislocation (luxation) or a subluxation of the thumb carpometacarpal joint, which have distinct codes.
