Sublux of metacarpal (bone), proximal end of left hand, subs

This code indicates a partial dislocation of the metacarpal bone at its proximal end within the left hand. This means the joint surfaces are no longer perfectly aligned but still maintain some contact. This specific code is for a subsequent encounter, meaning the patient is receiving follow-up care for this injury.

Apply this code when documenting ongoing treatment, follow-up appointments, or rehabilitation for a previously diagnosed subluxation of the proximal end of a left metacarpal. This includes scenarios where the patient is returning for cast changes, physical therapy, or re-evaluation of the healing process.

• Ensure the documentation clearly specifies "subluxation" and not a complete dislocation.
• Verify the laterality is correctly identified as the left hand.
• Confirm this is not the initial treatment for the injury; use the appropriate initial encounter code for the first visit.
