You would have to see if the timeline fits as this person was tested very late:

Pope Francis falls ill day after supporting people with coronavirus

Pope Francis has missed a planned Mass with clergy in Rome due to an unspecified illness. The Vatican said the pontiff, 83, had a ‘slight indisposition’ and would proceed with the rest of his planned work today but ‘preferred to stay near Santa Marta’, the Vatican hotel where he lives. There was no word from the Vatican about the nature of his illness, but the pope was seen coughing and blowing his nose during the Ash Wednesday Mass.

I found at least a somewhat plausible reason that the CDC might not have tested. It seems we have NL63 floating about:
This case was diagnosed Dec 23:

another coronavirus that attacks the heart:

2-3 days intubated in the initial hospital/transfer to Sacto, 5 days from transfer for CDC to test, report, and another 2 days to go public?
so, maybe a minimum of 20 days ago for infection? (mortality at 28 days avg?) So less than a week after the China nationals travel cutoff, which was lackadaisical for a week (as we saw/ heard).
Obviously the UCD patient can't talk. But he can't be an island, either. If this patient doesn't have any relatives who can tell us anything, what about an employer or landlord? Does he have a cellphone - can we do ping tracking? Is this person an illegal, migrant worker? or had contact with a person from a country that we hadn't yet added to the screen list the first week of Feb? Mystery Man.
