I have a question regarding visual field testing. There is a provider who employs a technician. This technician is doing the visual field testing for the provider and it is being billed out incident-to with the global fee because the provider owns the equipment. The visual field tests are said to only require "general supervision". The catch is that the provider is out of the country when these tests are being done, I wouldn't consider this general supervision. Does anyone have any information that could assist with this?
