Dislocation of distal interphalangeal joint of finger, init

This code signifies a complete separation of the bones forming the distal interphalangeal (DIP) joint in any finger other than the thumb. This injury involves the joint closest to the fingertip, where the middle phalanx meets the distal phalanx. The dislocation means the joint surfaces are no longer in their normal alignment.

Apply this code when documenting an initial encounter for a patient presenting with a dislocated DIP joint in the index, middle, ring, or little finger. This typically occurs due to trauma, such as a direct impact or hyperextension injury to the fingertip. It is used for the first time the patient is seen for this specific injury.

• Ensure the documentation specifies a DIP joint dislocation and not a sprain or subluxation.
• Verify that the affected finger is not the thumb, as thumb dislocations have separate codes.
• Confirm this is the initial encounter for treatment of this specific injury. Subsequent care will require a different seventh character.
