Below are a few of the most common questions we hear from new members.
If you sign up during the Annual Enrollment Period (AEP), your ID card should arrive in late December. If you enroll at another time, you’ll usually get your cards about two weeks before your coverage starts—but this can vary depending on the day you signed up. Your Flexible Benefit Card should arrive approximately three weeks after your enrollment is accepted.
Your Supplemental Benefit card is a paper card you cut out from one of the last pages of your Welcome Guide. This card should be presented to a provider when obtaining supplemental benefits like dental, hearing, and vision care. Your Supplemental Benefit card number is the same as your primary member ID. If you can't find your Supplemental Benefit card, use your member ID card wherever you receive care.
You can download a replacement Supplemental Benefit card here.
The Flexible Benefit Card is a Mastercard preloaded with allowances to use for over-the-counter (OTC), wellness, and non-emergency transportation supplemental benefits. This card is active on your first day of coverage and will be sent to you upon enrollment.
To use: Swipe your card and select credit. Each card is pre-assigned a PIN for situations where merchants require it. If prompted to enter a PIN, ask the merchant to process the transaction as credit so you can sign for your purchase instead. To request a PIN or view your available balance, visit mgbflexiblebenefits.org.
Your card can be used to purchase preapproved items at mgbflexiblebenefits.org or in person at participating retailers. For a complete list of eligible items and coverage details, please refer to your Evidence of Coverage (EOC) or contact Convey at 800-695-5306 (TTY: 711) Monday-Friday from 8 a.m. to 11 p.m. ET.
If you're having trouble with your flex card and make a purchase with your own money, you can fill out and submit a Flexible Benefit Card Reimbursement form, available on our Forms & Resources page.
If your plan has a premium and you are not set up for Social Security deduction, you will recieve a monthly paper bill. Payments are due by the first of the month for the previous month. For example: January payments are due February 1st. To pay your bill online or set up auto pay, visit Member.MGBHP.org, select Bill Payment, then Manage Bills.
If your premium is $300 or more per month, the Social Security Administration will not allow you to deduct your premiums from your Social Security wages.
If you are seeing an out-of-network dental provider, ask the provider to submit the claim directly to DentaQuest for payment. If the provider does not bill DentaQuest, you may request reimbursement by submitting a Reimbursement Form to DentaQuest Claims.
Before scheduling a dental procedure, please be aware, in-network providers should not be collecting money prior to insurance submission. Out-of-network providers may require you to pay for services up front. We will only reimburse out-of-network providers for services provided to you up to the in-network allowed amount. You may be required to pay the difference between the in-network allowed amount and the fee being charged by your provider, as well as any applicable cost-sharing.
To download and complete a Dental Reimbursement Form, visit our Forms & Resources page. View the DentaQuest tip sheet and Dental Plan Benefit Summary Procedure Codes here.
Mass General Brigham Health Plan gives you access to On Demand for convenient, high-quality urgent care. You can have an interactive video visit with a doctor right from your home, office, or anywhere in the US.

You can access the On Demand website on the Member Portal or via the MGB Health Plan On Demand app available for Android and iOS.

Once you’re registered, you’ll be able to see the next available provider.
You may get an extended (up to a 100-day) supply for many drugs through our mail order pharmacy. You can view which drugs do not allow an extended supply by searching the drug list within the Member Portal or by visiting our Rx Information page. Medications that do not allow an extended supply are marked as NDS in the drug list.
