Dislocation of oth carpometacarpal joint of unsp hand, subs

This code signifies a follow-up visit for a patient previously diagnosed with a dislocation of any carpometacarpal joint other than the thumb, in an unspecified hand. This injury involves the disruption of the articulation between the carpal bones and the metacarpal bones.

Apply this code for subsequent encounters such as cast changes, physical therapy sessions, follow-up imaging, or re-evaluations of the healing process for a previously treated carpometacarpal joint dislocation. This code is appropriate when the initial treatment has already been rendered and the patient is in the recovery phase.

• Ensure the encounter is for follow-up care, not the initial treatment of the dislocation.
• Confirm the dislocation involves a carpometacarpal joint other than the thumb (e.g., index, middle, ring, or little finger).
• If the laterality of the hand is known, a more specific code should be selected.
