Dislocation of oth carpometacarpal joint of left hand, subs

This code signifies a dislocation affecting a carpometacarpal joint in the left hand, excluding the thumb, that is currently under active treatment or healing. It indicates that the patient is receiving follow-up care for a previously diagnosed and treated dislocation at this specific joint.

Use this code for patients presenting for follow-up appointments, cast changes, physical therapy, or medication management related to a left-hand carpometacarpal joint dislocation (excluding the thumb) that has already received initial treatment. This applies when the injury is not new and the patient is in the healing or recovery phase.

• Ensure the documentation clearly specifies "left hand" and "other carpometacarpal joint" (i.e., not the thumb).
• Verify that the encounter is for subsequent care, not the initial treatment of the injury.
• Pair with an external cause code if the mechanism of injury is relevant and documented.
