Embolus detection code 93892 requires specialized equipment (hardware and software) and training by the physician to detect embolic events. The physician applies a small amount of water–soluble gel to the skin over the area to be examined, generally the base of the skull and the area over the ears. The physician holds a transducer in place on the skin's surface to record blood flow information. In 93892, the physician checks for emboli signals in the Doppler waveform, without the use of microbubble injection.
TCD is a noninvasive diagnostic ultrasound evaluation of the intracranial arteries. Neurologists and other physicians may order the test to determine whether there is an artery occlusion or stenosis that could result in cerebrovascular diseases such as stroke and brain hemorrhages. This test is used to search for emboli, intravascular masses capable of clogging arterial capillary beds. CPT codes 93890–93893 don't represent components of the complete TCD code. To the contrary, the services 93890–93893 represent require expertise, lab time, and equipment not included in the complete and limited codes.
