Certified Professional Coder (CPC) Practice Test

The diagnosis code that corresponds to COPD (Chronic Obstructive Pulmonary Disease) with emphysema is specific and includes a distinct coding system. In this case, the code 492.8 accurately reflects a diagnosis that encompasses COPD with emphysema since it is assigned for "other emphysema." This code describes a category of respiratory conditions where emphysema is present alongside COPD, emphasizing the chronic nature of the pulmonary obstruction that characterizes these diseases. Other options reference different types of respiratory conditions; for instance, 491.x pertains to chronic bronchitis, while 493.x codes are indicative of asthma-related conditions. Hence, 492.8 is the appropriate choice due to its specific linkage to emphysema, clarifying the nature of the patient's condition accurately within the coding standards used in medical documentation.
