About your plan
Your Medicare Advantage plan is insured and administered by Mass General Brigham Health Plan. We will manage your membership and support you in accessing your benefits. You’ll receive all of your benefit information and claims from Mass General Brigham Health Plan.
As a new member, one of our Care Guides will reach out by phone for a Welcome Call to help you get started with your new plan. They’ll explain your new benefits and help you access them. They can also help you find a primary care doctor and answer any questions about your medical, pharmacy, vision, dental, and wellness benefits. If you need to get in touch with a Care Guide again, you can request a call using the form at the bottom of this page or by calling Customer Service.

Frequently asked questions
Below are a few of the most common questions we hear from new members.
Your supplemental ID 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 ID number is the same as your primary member ID. If you can't find your supplemental ID card, use your member ID card wherever you get care.
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 MGBAdvantageOTC.org.
Your card can be used to purchase preapproved items at MGBAdvantageOTC.org or in person at participating retailers. For a complete list, please see your plan documents or contact Convey at (800) 695-5306 (TTY: 711) Monday - Friday from 8 a.m. to 11 p.m. ET.
For a full list of eligible items and coverage details, please refer to your Evidence of Coverage (EOC) or call Member Services for a copy.
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: July payments are due by August 1. To pay your bill online or set up auto pay, visit Member.MGBHP.org, select Bill Payment, and then Manage Bills.
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 claim to the plan.
Before scheduling a dental procedure, please be aware, we reimburse up to the Medicare Rate. This is the amount Medicare would pay for services and is generally less than the full amount a provider bills. You are responsible for any cost sharing for the visit, like copay or coinsurance, plus any difference between the Medicare Rate and the charged amount.
To download and complete a Medicare Dental Reimbursement Form, visit our Forms & Resources page.
