Dislocation of MCP joint of left middle finger, init

This code signifies a complete displacement of the joint between the metacarpal bone and the first phalanx of the left middle finger. This injury involves the disruption of the joint capsule and ligaments, leading to an abnormal alignment of the bones. Patients typically present with pain, swelling, and an inability to move the affected finger.

Apply this code when documenting the initial treatment for a patient presenting with a dislocated metacarpophalangeal joint of their left middle finger. This includes scenarios such as reduction procedures performed in the emergency department or an outpatient clinic, as well as initial evaluations prior to definitive treatment.

• Ensure documentation specifies the left middle finger and confirms a true dislocation, not a subluxation.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
• Do not use this code for follow-up care or sequelae; different seventh characters would apply.
