Final answer:
G Codes are used for collecting functional data. ICD-10 codes are utilized for diagnostic purposes and can be found on death certificates and medical laboratory test orders.
Step-by-step explanation:
The coding system used as a method of collecting functional data is the G Codes. These codes are part of the Medicare system and are used to report functional data, which provides information about a patient's functional limitations and the progress being made during the course of therapy services.
On the other hand, ICD-10 codes are used for diagnostic purposes, tracking the incidence and prevalence of diseases and other health problems. They are found on patients' medical records, such as their health summary and laboratory test orders. Medical professionals routinely use ICD codes when a patient is treated for conditions like viral infections. These codes guide the necessary laboratory tests and treatments and are used by various entities in the healthcare industry, from medical coders and billers to vital-records keepers and epidemiologists.
Two locations where you would likely find an ICD code are on death certificates and in medical laboratories. On death certificates, ICD codes record the cause of death, while medical laboratories use these codes to identify and perform the correct diagnostic tests.
