Are you referring to ICD-10 code U07.01? I thought the US had to wait for the WHO to add the code, so I'm not clear on how our health system was worse than other countries in that respect.
Yes, U07.1. I was not aware of the WHO aspect (only that it had to be accelerated.) Prior to April 1 there were several CDC guidances for covid that unfortunately were complicated by existing code re-use.
