Subluxation of carpometacarpal joint of right thumb, subs

This code signifies a partial dislocation of the joint connecting the thumb's metacarpal bone to the wrist bones (carpals) on the right hand. It indicates that the patient is receiving follow-up care for this specific injury, rather than initial treatment.

Apply this code for encounters where a patient is being seen for ongoing management, healing assessment, or rehabilitation of a previously diagnosed subluxation of the right thumb carpometacarpal joint. This includes visits for cast changes, physical therapy, or re-evaluation of the injury after initial treatment.

• Ensure documentation specifies "right thumb" and "carpometacarpal joint" for accurate laterality and anatomical site.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is in the healing or recovery phase.
• Do not use for initial treatment of the injury; a different seventh character would be appropriate for the initial encounter.
