Monoclonal Antibody Treatment

Medstar can provide monoclonal antibody (MAB) Bamlanivimab & Estesevimab and REGEN to high-risk COVID-19 patients.

A physician must complete this cover sheet and referral form and fax it with a face sheet that includes the patient's phone number to 586-371-5080. Patients covered by a Medicare Advantage plan must also include their Medicare number found on their Medicare card.

Upon receiving the completed referral and paperwork, Medstar will schedule the appointment with the patient.

Please note: our average turnaround time right now is three days after Medstar receives the completed paperwork and verifies the patient's information and eligibility; however, it may be longer based on demand.

The MAB treatment takes 15-30 minutes, and the Medstar clinician monitors the patient for an hour afterward. After the visit, Medstar will send the referring physician the completed form and chart from the appointment upon request.

It is the patient’s responsibility to check with their healthcare insurance provider about MAB coverage, co-pays, and deductibles. We recommend patients ask their healthcare insurance provider about coverage before their physician submits a referral.
