== Additional Info ==
*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 [[{{PAGENAME}}]] 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]]
