Official Coding Guidelines

COVID-19—code only confirmed cases; suspected/possible/probable/inconclusive

g. Coronavirus infections 1) COVID-19 infection (infection due to SARS-CoV-2) (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.

COVID-19 sequencing—U07.1 first when principal diagnosis unless exceptions

(b) Sequencing of codes When COVID-19 meets the definition of principal diagnosis, code U07.1, COVID-19, should be sequenced first, followed by the appropriate codes for associated manifestations, except when another guideline requires that certain codes be sequenced first, such as obstetrics, sepsis, or transplant complications.
