

1.C.1.g.1.a.

Code only a confirmed diagnosis of the 2019

novel coronavirus disease (COVID-19) as documented by

the provider, or documentation of a positive COVID-19 test

result, or a presumptive positive COVID-19 test result. 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 the type of test performed; the

provider’s documentation that the individual has COVID-19

is sufficient.



1.C.1.g.1.a. continued

Presumptive positive COVID-19 test results should be coded as

confirmed. A presumptive positive test result means an individual

has tested positive for the virus at a local or state level, but it has

not yet been confirmed by the Centers for Disease Control and

Prevention (CDC). CDC confirmation of local and state tests for

COVID-19 is no longer required.

If the provider documents "suspected," "possible," "probable," or

“inconclusive” COVID-19, do not assign code U07.1. Assign a

code(s) explaining the reason for encounter (such as fever) or

Z20.828, Contact with and (suspected) exposure to other viral

communicable diseases.

Instead, code the signs and symptoms

reported. See guideline I.C.1.g.1.g.

1.C.1.g.1.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 in the

case of obstetrics patients as indicated in Section . I.C.15.s. for

COVID-19 in pregnancy, childbirth, and the puerperium.

except

when another guideline requires that certain codes be sequenced

first, such as obstetrics, sepsis, or transplant complications.

See Section I.C.16.h. for COVID-19 infection in newborn

For a COVID-19 infection in a lung transplant patient, see Section

I.C.19.g.3.a. Transplant complications other than kidney.

Acute respiratory illness due to manifestations of

The following conditions are examples of common respiratory manifestations of COVID-19.

(i) Pneumonia

For a patient with pneumonia case confirmed as due to the 2019 novel coronavirus (COVID-19), assign codes U07.1, COVID-19, and J12.89, Other viral pneumonia.

manifestation (e.g., viral enteritis) of COVID-19, assign code U07.1, COVID-19, as the principal/first-listed diagnosis and assign code(s) for the

manifestation(s) as additional diagnoses.

1.C.1.g.1.e. Exposure to COVID-19

For cases where there is a concern about a possible exposure to COVID-19, but this is ruled out after evaluation, assign code Z03.818, Encounter for observation for suspected exposure to other biological agents ruled out.

For asymptomatic individuals with actual or suspected exposure to COVID-19, assign code Z20.828, Contact with and (suspected) exposure to other viral communicable diseases.

For cases where there is an symptomatic individuals with actual or suspected exposure to someone who is confirmed or suspected (not ruled out) to have to COVID-19, and the exposed individual either tests negative or the test results are unknown, and the infection has been ruled out, or test results are inconclusive or unknown, assign code Z20.828, Contact with and (suspected) exposure to other viral communicable diseases. If the exposed individual tests positive for the COVID-19 virus, see guideline a). See guideline I.C.21.c.1, Contact/Exposure, for additional guidance regarding the use of category Z20 codes.

For asymptomatic individuals who are being screened for COVID-19 and have no known exposure to the virus, and the test results are either unknown or negative, assign code Z11.59, Encounter for screening for other viral diseases. For individuals who are being screened due to a possible or actual exposure to COVID-19, see guideline d).

If an asymptomatic individual is screened for COVID-19 and tests positive, see guideline g).

During the COVID-19 pandemic, a screening code is generally not appropriate. For encounters for COVID-19 testing, including preoperative testing, code as exposure to COVID-19 (guideline I.C.1.g.1.e).

Coding guidance will be updated as new information concerning any changes in the pandemic status becomes available.

has an actual or suspected contact with or exposure to someone

who has COVID-19, assign Z20.828, Contact with and (suspected)

exposure to other viral communicable diseases, as an additional

code. This is an exception to guideline I.C.21.c.1,

Contact/Exposure.

 2.C.1.g.1.h. Asymptomatic individuals who test positive for COVID-19

For asymptomatic individuals who test positive for COVID-19,

the individual is asymptomatic, the individual has tested positive

I.C.10.e. Vaping-related disorders

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. Assign additional codes for other manifestations, such as acute respiratory failure (subcategory J96.0-) or pneumonitis (code J68.0).

Associated respiratory signs and symptoms due to vaping, such as cough, shortness of breath, etc., are not coded separately, when a definitive diagnosis has been established. However, it would be

appropriate to code separately any gastrointestinal symptoms, such as diarrhea and abdominal pain.

1.C.21.c.3. Status

Z79 Codes from this category indicate a patient’s continuous

use of a prescribed drug (including such things as aspirin

therapy) for the long-term treatment of a condition or for

prophylactic use. It is not for use for patients who have

addictions to drugs. This subcategory is not for use of

medications for detoxification or maintenance programs to

prevent withdrawal symptoms in patients with drug

dependence (e.g., methadone maintenance for opiate

dependence). Assign the appropriate code for the drug

dependence instead.

I.C.21.c.6 Observation

The observation codes are primarily to be used as principal/first-listed diagnosis only. An observation code may be assigned as a secondary

diagnosis code when the patient Is being observed for a condition that is ruled out and is unrelated to the principal/first-listed diagnosis (e.g., patient presents for treatment following injuries sustained in a motor vehicle accident and is also observed for suspected COVID-19 infection that is subsequently ruled out). The only exception to this is Also when the principal diagnosis is required to be a code from

category Z38, Liveborn infants according to place of birth and type of delivery, then Then a code from category Z05, Encounter for

observation and evaluation of newborn for suspected diseases and conditions ruled out, is sequenced after the Z38 code. Additional codes may be used in addition to the observation code, but only if they are unrelated to the suspected condition being observed.
