Final answer:
The correct CPT code for a returning patient diagnosed with pneumonia following a CT Chest with contrast is 99214, as it matches the requirements for a detailed examination and medical decision-making of moderate complexity. Option C is correct.
Step-by-step explanation:
The question pertains to the proper coding for a return patient visit in a medical setting, where a diagnostic imaging procedure—a CT Chest with contrast—was performed, and a diagnosis of pneumonia was established. In the context of the American Medical Association's Current Procedural Terminology (CPT) codes, which are used for billing purposes, the codes mentioned (99215, 99213, 99214, 99204, 99205) represent different levels of office or other outpatient visit services.
For a returning patient diagnosed with pneumonia after a CT Chest with contrast, the appropriate code would generally depend on the complexity of the medical decision-making, the amount of time spent with the patient, and the detailed nature of the examination. Among the choices provided, code 99214 is the correct option for an outpatient or office visit that includes a detailed history, a detailed examination, and medical decision-making of moderate complexity.
It is important to note that coding should always be done based on the individual circumstances of the patient's visit and the documentation provided by the healthcare provider. Coders need to ensure that all the requirements are met for the specific CPT code chosen.
