Disloc of metacarpal (bone), proximal end of unsp hand, subs

This code signifies a dislocation at the proximal end of a metacarpal bone, meaning the end closer to the wrist, in an unspecified hand. This injury involves the displacement of the metacarpal from its normal articulation with the carpal bones. The "subsequent encounter" designation indicates that the patient is receiving follow-up care for this previously diagnosed and treated injury.

Apply this code when a patient presents for ongoing treatment, such as cast changes, physical therapy, or follow-up evaluations, for a dislocation of the proximal metacarpal in either hand. This code is appropriate after the initial treatment of the dislocation has already occurred. It should be used for any encounter after the initial reduction and stabilization.

• Ensure documentation specifies the proximal end of the metacarpal was dislocated, not the distal end.
• Confirm the encounter is for follow-up care, not the initial treatment of the injury.
• If the laterality (left or right hand) is documented, a more specific code should be used.
