- Follow the same rules as usual for Primary Admit Diagnosis; that way our long term reporting doesn't get any weird discontinuities and if we need to report something for COVID we can still find that it was associated with the same priority:
- it's only the primary if it meets the criteria in Primary Admit Diagnosis, e.g. if they also have a stroke or trauma COVID might not be related to primary at all
- code the infection as primary, not the pathogen
- This is a code for a viral pathogen officially called "SARS-COV-2". It causes a disease called "COVID-19", that has multiple infectious manifestations, with more likely to be identified over time.
- The main manifestation known as of January 2021 is a viral pneumonia which can evolve into ARDS (noncardiogenic pulmonary edema). To code this viral pneumonia, use Pneumonia, viral with the bug being COVID-19 (SARS-COV-2).
- If as may be the case, there is a viral encephalopathy due to this bug, then you'd code it as Encephalitis, meningoencephalitis, myelitis, encephalomyelitis, viral with the bug being the same.
- If you have an asymptomatic patient who has tested positive, you can link this with Carrier of infectious disease, unspecified.
- If you have a covid positive patient with GI symptoms only, you can combine with Gastrointestinal infection (gastroenteritis, colitis), viral
- Once active infection is gone (even if manifestations such as respiratory fibrosis and respiratory failure remain and continue to be coded) we will NOT use this code. Specifically, we do not have a coded for past history of COVID-19.
- Thus, this code should not be used as a comorbid diagnosis.
- Also, do not use this to code non-infectious complications or sequelae of COVID-19 -- see Post COVID-19 condition
- The majority of COVID Pos patients have myalgias, fatigue, or malaise. We do not collect this as per Template:ICD10 Guideline Signs Symptoms Test Results not needed when cause known
Data Collection Instructions
Will be used for MCHP (Manitoba Center for Health Policy)
Data about COVID is sent to MCHP so please adhere to the guidelines below closely so our data is well understood.
Coding Suspected infection
If patient is a COVID suspect- combine COVID-19 (SARS-COV-2) with Observation for suspected infection NOS linked with the same number (don’t link it with any other infection code if not confirmed) Leave the code in, even if they later come up as a negative.
This should be coded on admission (if applicable) but subsequent swabs sent during the admission should not be coded as acquired diagnosis, unless the Swab is positive, then follow the usual guidelines for coding an acquired infection.
Coding symptomatic infection
Coding asymptomatic infection
Coding hospital acquired COVID
Add Nosocomial_infection,_NOS to what you would already code for this infection (ie might be different if symptomatic or not, or suspected etc, use the rules described elsewhere for that part).
Enter CCI Isolation, infectious if it is happening
- As we do with all infections, we do the best possible to identify the bug. Sometimes we're left without a clear, laboratory identification of the bug and then we use one or another of the "wastebasket codes"
If the team believes that this is COVID-19 (even without clear cut lab confirmation), then use COVID-19 (SARS-COV-2) as the organism - of course anybody seeking to do definitive analysis of all COVID-19 cases will need to obtain and use the data on confirmed cases from Cadham.
Done by Cadham Lab
Delayed lab results
- Regarding people who either die or are discharged from hospital with their COVID-19 lab test still pending, follow the usual rules i.e: Lab_and_culture_reports#How_long_to_wait_for_a_result or Attribution of infections
- Note that this test is done by Cadham Lab and not by the usual DSM lab.
When info about COVID status is found out long after locations are entered
When Reviewing a chart in MR and you find a COVID positive or COVID suspect patient that occurred BEFORE the new COVID positive/suspect wards were opened, use Service Location home ward location and use the appropriate COVID-19 (SARS-COV-2) or Observation for suspected infection NOS code.
When reviewing a chart in MR and you find a COVID suspect patient on your home ward and the patient is transferred to another location where the diagnosis of COVID positive is made, check the date/time the swab was sent. If it was sent less than 48 hours after admission code this as an Admit Diagnosis, if the swab was sent greater than 48 hours after admission code this as an Acquired Diagnosis
Alternate ICD10s to consider coding instead or in addition
Only use this for COVID-19 (SARS-CoV-2) - not other Coronavirus
