Fracture of one rib, left side, init for opn fx

This code signifies a broken rib on the patient's left side where the skin and soft tissue have been compromised, exposing the fracture site. This is the first time the patient is receiving active treatment for this specific injury.

Apply this code when documenting the initial treatment for a patient presenting with a left-sided rib fracture that is visibly open, such as a compound fracture where bone protrudes through the skin or there's a wound communicating with the fracture. This is appropriate for emergency department visits, initial hospital admissions, or the first outpatient encounter for definitive care.

• Ensure documentation clearly specifies "left side" and "open fracture."
• Confirm this is the initial encounter for active treatment; subsequent care would use a different encounter character.
• Always code any associated external cause of injury (e.g., fall, motor vehicle accident) as a secondary diagnosis.
