Subluxation of MCP joint of left little finger, init

This code signifies a partial dislocation of the joint connecting the metacarpal bone to the first phalanx of the left little finger. The joint surfaces are no longer in complete alignment, but remain in partial contact. This injury typically results from trauma or forceful hyperextension.

Apply this code when documenting the initial treatment for a patient presenting with a subluxation of the metacarpophalangeal joint of their left little finger. This includes the evaluation, diagnosis, and initial management of the injury.

• Ensure the documentation clearly specifies "subluxation" and not a full "dislocation" (which would be a different code series).
• Verify the laterality (left) and the specific digit (little finger) are accurately documented.
• The "A" in the seventh character indicates an initial encounter for active treatment of the injury.
