Additional Info

For people who are admitted with Covid-19 pneumonia, should COVID-19 be the primary diagnosis or pneumonia, viral? I would normally do pneumonia not the organism, but I'm wondering for COVID data collection if the process is different. |
- This is intrinsically a code for a viral pathogen officially called "SARS-COV-2". It causes a disease called "COVID-19", that has multiple manifestations, with more likely to be identified over time.
- The main manifestation known as of April 2020 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 Viral infection, NOS.
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.
Coding symptomatic infection
COVID positive patients- combine COVID-19 (SARS-COV-2) with other appropriate diagnosis such as Pneumonia, viral, ARDS (noncardiogenic pulmonary edema)
Coding asymptomatic infection
Combine COVID-19 (SARS-COV-2) with Viral infection, NOS
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).
Isolation
Enter CCI Isolation, infectious if it is happening
Infection status
- 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"
- For example if the team believes this is likely a virus but doesn't know which one then use Virus, NOS
- For example if the team doesn't know what kind of bug it is, but believes it is infectious then use Infectious organism, unknown
Presumed infections
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.
Confirmed infections
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.
Cohorting in HSC ICUs
As of 2020-04-01 at HSC all CC patients with an "unknown" contact history (even traumas and emergent OR's) are admitted to MICU first, and once their COVID swab comes back negative they are moved to SICU where they normally would be admitted (tracked in ICUotherService).
To show that a patient like this is in MICU rather than SICU, code Observation for suspected infection NOS with COVID-19 (SARS-COV-2) as one of the later codes, but still code the Primary Admit Diagnosis as the thing that put them in an ICU, ie. the trauma or the emergent OR.
Special Circumstances
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
