Displaced Rolando's fracture, unsp hand, init for opn fx

This code signifies a fracture of the base of the thumb metacarpal (first metacarpal) that extends into the carpometacarpal joint, characterized by multiple fracture fragments and displacement. It is an open fracture, meaning the skin and soft tissues have been compromised, exposing the bone to the external environment. This specific code is used for the initial treatment encounter when the affected hand is not specified.

Apply this code for the initial encounter of a patient presenting with an open, comminuted, and displaced fracture at the base of the first metacarpal. This is appropriate when the medical record does not specify whether the injury is to the left or right hand. This code is used for the initial phase of care, including diagnosis and definitive treatment.

• Ensure documentation clearly states "open fracture" and "displaced Rolando's fracture."
• Only use this code for the initial encounter; subsequent encounters will require different seventh characters.
• If the hand (left or right) is specified in the documentation, a more specific code should be selected.
