My primary care Dr told me to go to the ER. He said if he had attempted to order all the necessary test and work up required, it would have been a nightmare to get the approvals through my insurance. Although I was in the ER for 4 hours, I was able to get a complete work up, X-rays, CT scan with contrast, all blood work, consultation with an infectious disease expert and a pneumenologist, all without flack from my insurance company.
