Dislocation of MCP joint of left index finger, init

This code signifies a complete displacement of the joint between the metacarpal bone and the first phalanx of the left index finger. This injury involves the disruption of the normal articulation of these bones, often resulting in visible deformity and significant pain.

Apply this code when documenting the initial treatment for a patient presenting with a dislocated metacarpophalangeal joint of their left index finger. This includes cases resulting from trauma, such as a fall or direct impact, where the joint has been forced out of alignment.

• Ensure laterality (left) and finger (index) are accurately documented in the medical record.
• Verify that this is the initial encounter for this specific injury, as subsequent encounters will use different seventh characters.
• Look for documentation of reduction (open or closed) and any associated injuries to other structures.
