Tufts Health One Care (HMO D-SNP)

We are happy to have you as a member and to be a part of your health care journey.

Starting January 1, 2026, Tufts Health One Care will be a Dual Eligible Special Needs Plan (HMO D-SNP). Tufts Health One Care will still combine the benefits of your MassHealth (Medicaid) and Medicare coverage through one health plan. But there will be some important changes and new benefits.

This page is your guide for what you need to know. Be sure to read your 2026 Tufts Health One Care member materials for more information. 

You will receive a new member ID number and ID card in the mail, so please keep an eye out for it. Keep using your current ID card through December 31, 2025. On January 1, 2026, you can throw away your current member ID card and begin using the new card you receive in October or later if you’re a new Tufts Health One Care member. 

 

Here's what your 2025 Tufts Health One Care ID card looks like. Please use this card through December 31, 2025. You can throw out your old card after this date.

 

 

Here's what your 2026 Tufts Health One Care ID card will look like. Please start using this ID card on January 1, 2026. Show your new card at your doctors' offices or pharmacy.

 

Your new ID card will have a gold bar on the bottom of the card. Your member ID number is also changing for 2026.

Instant Savings Card

Members receive a quarterly allowance to spend on select over-the-counter (OTC) health, hygiene and grocery products at participating retailers. The Instant Savings card gives you $155 per quarter or a total of $620 per year. You can use the card to buy Medicaid and Medicare approved items, such as adhesive bandages, toothbrushes, sunscreen, shampoo, select groceries and more!

How it works:

At the beginning of each of the four calendar quarters (in January, April, July and October), your Instant Savings card is automatically loaded with $155.

Your balance does not carry over, so try to spend the full amount before the end of each calendar quarter.

Don’t throw out your card. It will be reloaded at the start of each calendar quarter. 

Watch your mail. Your Instant Savings Card will be mailed to you this December, or shortly after you enroll. You can begin using your card on or after January 1, 2026. 

Dental benefits

Dental health is essential for your overall health and wellbeing. Learn about new dental benefits coming in 2026, including our new implants benefit. Find more information in your Member Handbook.

Members who wear eyeglasses can enjoy more covered options when choosing new lenses and frames in 2026. Find more information in your Member Handbook.

2026 member plan materials

All of your 2026 member materials are available online. Visit TuftsHealthOneCare.org to see your Member Handbook, Summary of Benefits, List of Covered Drugs, Provider and Pharmacy Directory and Annual Notice of Changes. 

Care management

You will continue to receive Care Management services through Cityblock Health. Cityblock is your dedicated team of doctors, nurses, mental health advocates and social workers who will work with you, listen, and do whatever it takes to get you the care you need.

In 2022, the Centers for Medicare and Medicaid Services (CMS) announced the decision to convert all Medicare-Medicaid Plans, like Tufts Health One Care, to Dual Eligible Special Needs Plans. To be eligible for Tufts Health One Care, you still will need to be eligible for MassHealth (Medicaid) and Medicare. 

Current Tufts Health One Care members will be given new ID numbers that are effective January 1, 2026. Members will be mailed new member ID cards with their new member ID number in October 2025.

Members will get new benefits in 2026, including an Instant Savings Card for eligible purchases, and enhanced dental and vision benefits. Please see your 2026 Tufts Health One Care Member Handbook for more details. 

The images below show the differences between the 2025 and 2026 member ID cards. Your new ID card will have a gold bar on the bottom of the card. Your member ID number is also changing for 2026.

Any active PA existing Tufts Health One Care members have in place will continue in 2026. If you have PA to see an out-of-network provider, make sure your PA is active before you seek care from that provider to ensure that you are not liable for any out-of-pocket costs. When in doubt, ask your care coordinator or call Member Services.

No. Current Tufts Health One Care members are not required to re-enroll with the plan or MassHealth (Medicaid).
