Dislocation of MCP joint of left little finger, init

This code signifies a complete displacement of the joint between the metacarpal bone and the proximal phalanx of the left little finger. This injury involves the disruption of the joint capsule and ligaments, leading to an abnormal alignment of the bones.

Apply this code when documenting the initial treatment for a patient presenting with a dislocated left little finger at the metacarpophalangeal joint. This includes cases seen in the emergency department, urgent care, or a physician's office for the first time following the injury.

• Ensure the documentation specifies the "initial encounter" for this injury.
• Verify the affected digit is explicitly stated as the "little finger" and the side as "left."
• Confirm the joint involved is the metacarpophalangeal joint, not the interphalangeal joints.
