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

This code signifies a fracture of the base of the first metacarpal (thumb) that extends into the carpometacarpal joint, without displacement of the bone fragments. It specifically indicates an open fracture, meaning the skin and soft tissue overlying the fracture site have been compromised, exposing the bone. This is the initial encounter for treatment of this specific injury.

Use this code for a patient presenting for the first time with a Rolando's fracture of the thumb that is documented as nondisplaced and open. This would typically be seen in emergency department visits or initial orthopedic consultations following a traumatic injury. It is crucial to confirm the "open" nature of the fracture and the "nondisplaced" status.

• Always verify documentation explicitly states "nondisplaced" and "open fracture" for the Rolando's fracture.
• Ensure this is the patient's initial encounter for this specific injury; subsequent care would require a different encounter character.
• Laterality is unspecified for this code, so if the hand is documented (e.g., left or right), a more specific code should be sought.
