Final answer:
It is true that additional signs and symptoms that are not commonly associated with a disease should be coded when they are present, as they could provide a more complete understanding of the patient's health.
Step-by-step explanation:
It is true that additional signs and symptoms not routinely associated with a disease process should be coded when present. Medical professionals analyze signs and symptoms extensively when diagnosing a disease and determining the appropriate treatment plan. While some diseases might not produce unique symptoms, making diagnosis complex, it is vital to recognize and document even atypical signs and symptoms as they could reveal a more comprehensive understanding of the patient's condition. For instance, asymptomatic diseases may not present noticeable signs or symptoms, but deviations in test results like antibody presence can indicate a condition that requires attention and potentially different therapeutic approaches.
