Coronavirus (COVID-19)

In light of the current Coronavirus (COVID-19) outbreak, the Trust wants to reach out to you with the enclosed Coronavirus (COVID-19) Fact Sheet that our telemedicine partner SwiftMD Physicians have put together for all plan participant members. SwiftMD doctors can provide consults for members who are suffering from symptoms of upper respiratory illness and are concerned they might have COVID-19. Our doctors can answer questions about COVID-19 and help a member assess their risk factors, such as whether they have traveled to a high-risk area or been exposed to anyone who has traveled to a high-risk area or has tested positive for COVID-19.  For most patients, the illness will be mild and our doctors recommend that patients with minor symptoms stay home to recover rather than go in to be tested. There is currently no antiviral treatment or vaccine for COVID-19, but our doctors can provide supportive care to alleviate symptoms. SwiftMD Physicians cannot definitively diagnose COVID-19 via telemedicine and cannot order tests for the virus. For a definitive diagnosis of COVID-19, members will need to contact their PCP’s office to arrange for the necessary testing through their local health department, LabCorp or Quest Diagnostics. If their symptoms become severe, members should seek care in person at an ER.  If a member does get a COVID-19 diagnosis, their PCP or specialist physicians should manage their ongoing care and recovery, including providing the FMLA paperwork that would be needed for a longer term absence.
