Final answer:
The statement is true; conditions are not coded in diagnostic test reports unless confirmed by a physician.
Step-by-step explanation:
The statement that conditions listed in diagnostic test reports are not coded unless the diagnosis is confirmed by a physician is true. Medical professionals utilize a variety of diagnostic methods to ascertain the cause of a patient's symptoms. While signs and symptoms can guide healthcare providers toward a preliminary diagnosis, few diseases present with unique symptoms that are exclusive to them. Consequently, it is often crucial to confirm the disease or condition with additional direct or indirect diagnostic methods. Final coding of a diagnosis in a patient's medical records usually awaits confirmation from a physician, who can certify the diagnosis after interpretation of the test results and clinical assessment.
