- Pneumonia – Assign codes U07.1, COVID-19, and J12.82, Pneumonia due to coronavirus disease 2019.
- Acute bronchitis – Assign codes U07.1, and J20.8, Acute bronchitis due to other specified organisms. Bronchitis not otherwise specified (NOS) due to COVID-19 should be coded using code U07.1 and J40, Bronchitis.
- Lower respiratory infection – If the COVID-19 is documented as being associated with a lower respiratory infection, not otherwise specified (NOS), or an acute respiratory infection, NOS, codes U07.1 and J22. If the COVID-19 is documented as being associated with a respiratory infection, NOS, codes U07.1 and J98.8.
- Acute respiratory distress syndrome – For acute respiratory distress syndrome (ARDS) due to COVID-19, assign codes U07.1, and J80.
- Acute respiratory failure – For acute respiratory failure due to COVID-19, assign code U07.1, and code J96.0-.

- Exposure to COVID-19 – For asymptomatic individuals with actual or suspected exposure to COVID-19, assign code Z20.822, Contact with and (suspected) exposure to COVID-19. For symptomatic individuals with actual or suspected exposure to COVID-19 and the infection has been ruled out, or test results are inconclusive or unknown, assign code Z20.822, Contact with and (suspected) exposure to COVID-19.
- Screening for COVID-19 – During the COVID-19 pandemic, a screening code is generally not appropriate. Do not assign code Z11.52, Encounter for screening for COVID-19. For encounters for COVID-19 testing, including preoperative testing, code as exposure to COVID-19 (guideline I.C.1.g.1.e).
- Signs and symptoms without definitive diagnosis of COVID-19 – Assign the appropriate code(s) for each of the presenting signs and symptoms (ex. R05 Cough, R06.02 Shortness of breath, R50.9 Fever, unspecified)
- Asymptomatic individuals who test positive for COVID-19 – For asymptomatic individuals who test positive for COVID-19, see guideline I.C.1.g.1.a. The individual has tested positive and is considered to have the COVID-19 infection.
- Personal history of COVID-19 – Assign code Z86.16, Personal history of COVID-19.

- Encounter for antibody testing – Assign Z01.84, Encounter for antibody response examination.
- Multisystem Inflammatory Syndrome – For individuals with multisystem inflammatory syndrome (MIS) and COVID-19, assign code U07.1 and M35.81. If MIS develops as a result of a previous COVID-19 infection, assign codes M35.81 and B94.8. If an individual with a history of COVID-19 develops MIS and the provider does not indicate the MIS is due to the previous COVID-19 infection, assign codes M35.81 and Z86.16. If an individual with a known or suspected exposure to COVID-19, and no current COVID-19 infection or history of COVID-19, develops MIS, assign codes M35.81 and Z20.822.
Vaping-related disorders – Page 58-59
For patients presenting with condition(s) related to vaping, assign code U07.0, Vaping-related disorder, as the principal diagnosis. For lung injury due to vaping, assign only code U07.0.

During pregnancy, childbirth or the puerperium, when COVID-19 is the reason for admission/encounter, code O98.5-, Other viral diseases complicating pregnancy, childbirth and the puerperium, should be sequenced as the principal/first-listed diagnosis, and code U07.1, COVID-19, and the appropriate codes for associated manifestation(s) should be assigned as additional diagnoses.
