Effective October 1, 2011, codes 518.51, Acute respiratory failure following trauma and surgery; 518.52, Other pulmonary insufficiency, not elsewhere classified; and 518.53, Acute and chronic respiratory failure following trauma and surgery, have been created to distinguish postoperative acute respiratory failure from less severe respiratory conditions such as shock lung, drowned lung, pulmonary and lung insufficiency following shock, surgery or trauma, wet lung syndrome, adult respiratory distress syndrome (following shock, surgery, or trauma) and acute idiopathic lung congestion; conditions that only require supplemental oxygen or intensified observation.
Respiratory failure is a relatively common postoperative complication that often requires mechanical ventilation for more than 48 hours after surgery or reintubation with mechanical ventilation after postoperative extubation. Risk factors may be specific to the patient's general health, location of the incision in relation to the diaphragm, or the type of anesthesia used for surgery. Trauma to the chest can lead to inadequate gas exchange causing problems with levels of oxygen and carbon dioxide. Respiratory failure results when oxygen levels in the bloodstream become too low (hypoxemia), and/or carbon dioxide is too high (hypercapnia), causing damage to tissues and organs, or when there is poor movement of air in and out of the lungs. In all cases, respiratory failure is treated with oxygen and treatment of the underlying cause of the failure.
