I.C.1.g.1)(a)

Code only confirmed cases

Code only a confirmed diagnosis of the 2019 novel coronavirus disease (COVID-19) as documented by the provider. For a confirmed diagnosis, assign code U07.1, COVID-19. This is an exception to the hospital inpatient guideline Section II, H. In this context, “confirmation” does not require documentation of a positive test result for COVID-19; the provider’s documentation that the individual has COVID-19 is sufficient.

If the provider documents "suspected," "possible," "probable," or “inconclusive” COVID-19, do not assign code U07.1. Instead, code the signs and symptoms reported. See guideline I.C.1.g.1.g.
