Examples of ICD 10 Covid 19 cases with answers

Example #1
 Question: Inpatient is tested for COVID and the test comes back negative, but positive for pneumonia and the flu. Should we be using the Z code in addition to the diagnosis of flu and pneumonia?
 Answer:
Assign codes for the flu and pneumonia
Z20.828, Contact with and (suspected) exposure to other
viral communicable diseases

Examples #2
 Question: Patient was admitted for liver transplant rejection and 10 days into the admission the patient develops new onset cough, runny nose and tests positive for coronavirus. Documentation shows COVID-19 with very mild symptoms. How should this be sequenced?
Answer:
Principal diagnosis: T86.41, Liver transplant rejection
Secondary diagnosis: U07.1, COVID-19

Example #3
 Question: Patient is admitted with pneumonia due to COVID-19 which then progresses to viral sepsis. How should this be reported?
Answer:
Principal diagnosis: U07.1, COVID-19
Secondary diagnosis:
A41.89, Other specified sepsis
J12.89, Other viral pneumonia

Example #4
 Question: If a patient is admitted with sepsis due to COVID-19 pneumonia. Would code U07.1 be assigned as the principal diagnosis?
Answer:
Principal diagnosis: A41.89, Other specified sepsis
Secondary diagnosis: U07.1, COVID-19
J12.89, Other viral pneumonia

Example #5
 Question: Does code U07.1 apply to all healthcare settings? For example, can it be used as the primary code for home health services or rehab facilities?
Answer: Code U07.1, COVID-19, has part of the official ICD-10-CM code set effective April 1, 2020. As such, it is the HIPAA code set standard for diagnosis coding in all care settings.
If the reason for the encounter is COVID-19, then code U07.1 may be applied, depending on the circumstances of admission/encounter.

Example #6
 Question: Does a provider need to explicitly link the results of the COVID19 test to the respiratory condition as the cause of the respiratory illness?
Patients are being seeing in our ED and if results are not available, we are reluctant to query the physicians to go back and document the linkage when the results come back.
Answer: No, the provider does not need to explicitly link the test result to the respiratory condition, as long as there is documentation of a positive COVID-19 test result in the record.
We recommend that providers consider developing facility-specific coding guidelines to hold back coding of inpatient admissions and outpatient encounters until the test results for COVID-19 testing are available.
This advice is limited to cases related to COVID-19
