Final answer:
ICD codes are found in medical laboratories where tests are identified and in health-care management systems for verifying treatment alignment. Additionally, they are used by medical coders and billers, on death certificates, and in public health research.
Step-by-step explanation:
When attempting to identify two locations where you might find an ICD code, it is critical to understand that these codes are extensively used in the health care environment. One primary location where an ICD code is likely to be used is in a medical laboratory. Here, ICD codes help to identify tests that must be performed to confirm a patient's diagnosis. Another important location is within the health-care management system, where ICD codes enable verification that all treatments and laboratory work are aligned with the patient's diagnosis.
Medical coders and billers also heavily rely on ICD codes. Coders assign the appropriate code for procedures performed during a patient visit, while billers utilize these codes to process insurance claims for reimbursement. Moreover, vital-records keepers reference ICD codes for recording the cause of death on death certificates, which are a matter of public record. Additionally, epidemiologists employ these codes when calculating morbidity and mortality statistics, essential for public health monitoring and research.
