This code signifies a complete displacement of the bones forming the interphalangeal joint of the thumb, where the joint surfaces are no longer in proper alignment. This injury specifically refers to the single joint within the thumb's phalangeal bones, not the joint connecting the thumb to the hand.

Use this code for the initial treatment of a patient presenting with a dislocated interphalangeal joint of an unspecified thumb. This includes the first time the patient is seen for this specific injury, whether in an emergency department, urgent care, or physician's office.

• Requires a 7th character extender; 'A' indicates the initial encounter for active treatment.
• Laterality (left or right thumb) is not specified for this particular code.
• Ensure documentation clearly states "dislocation" of the interphalangeal joint of the thumb.
