Question: For PET/CT CPT codes 78814-78816, ACR recommends a glucose check prior to the scan. Is there a way to avoid this test's being a CMS write-off due to medical necessity? Answer: Probably not -- many facilities treat the blood glucose test as part of the price of performing the PET/CT scan.

Arguing that the test is diagnostic -- in the sense of diagnosing or treating an illness -- would be tough, which is why Medicare doesn't cover it.
