Subluxation of oth carpometacarpal joint of right hand, init

This code signifies a partial dislocation of a carpometacarpal joint in the right hand, excluding the thumb carpometacarpal joint. It indicates that the joint surfaces are no longer perfectly aligned but still maintain some contact. This injury often results from trauma or repetitive stress.

Apply this code when documentation specifies a subluxation of any carpometacarpal joint of the right hand, other than the first (thumb) carpometacarpal joint. This is appropriate for the initial visit where the injury is first evaluated and treated.

• Ensure the documentation specifies "subluxation" and not a full "dislocation" (which would use a different code).
• Verify the laterality is "right hand" and the specific carpometacarpal joint is not the thumb.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
