Learn about our 2027 plan changes

You can enroll in another Mass General Brigham Health Plan Medicare Advantage plan, select a Medicare Advantage plan from another insurer, or return to Original Medicare. We can help you understand these options and determine which may best meet your needs.

If you are interested in switching to another Mass General Brigham Medicare Advantage plan, our Medicare Advisors can walk you through available plan options, network providers, and benefits. You can also compare all Medicare coverage options by contacting Medicare directly at 800-MEDICARE or visiting Medicare.gov. 

You can make changes to your Medicare health coverage during certain times of the year, including the Annual Enrollment Period from October 15 through December 7 and the Medicare Advantage Open Enrollment Period from January 1 through March 31. 

Many members will still have access to the providers they know and trust through our available Medicare Advantage plan options. Provider networks can vary by plan, so we can help you review whether your current doctors, specialists, or care team participate in the plan you are considering.

You can use our provider directory to search for your doctor, specialist, hospital, or other healthcare provider. If your provider practices at multiple locations, check the specific location where you plan to receive care, as network participation may vary. If you need assistance, please contact Member Services. 

The main difference is how the plans are structured and how you access care. With an HMO-POS plan, you will need to choose a primary care provider and obtain referrals for certain specialist services. Out-of-network coverage may be limited depending on your plan type. Premiums, cost sharing, prescription drug coverage, and additional benefits can also vary. 

A referral comes from your primary care provider and directs you to see a specialist. A prior authorization is approval from the health plan that may be required before certain services, procedures, or medications are covered. 

You can still see an out-of-network specialist, however your cost sharing will be higher than if you see an in-network provider. Contact us and we'll help you understand your coverage and any costs you may be responsible for.

Emergency and urgently needed care are covered regardless of where they occur. Coverage for routine care depends on your plan's network and benefits. We can review any specific hospitals or providers if you'd like. 

You can still see an out-of-network specialist, however your cost sharing will be higher than if you see an in-network provider. Contact us and we'll help you understand your coverage and any costs you may be responsible for.

As a Medicare Advantage member, you have the right to raise concerns, ask questions, file complaints (called grievances), and request a review of certain coverage or payment decisions through the appeals process. You can contact Member Services for help understanding your options and submitting a grievance or appeal. Member Services can explain the process, answer questions, and provide any needed forms. 

You received separate letters that address separate changes, which may affect your coverage in 2027. One letter explains changes to our Medicare Advantage plan offerings, while the other covers provider network changes involving Dana-Farber Cancer Institute. Federal Medicare rules require health plans to notify members about these changes on different timelines. We coordinated the mailings as closely as possible within those requirements so you would receive timely information, understand your options, and make informed decisions about your coverage and care.
