If a blue envelope from MassHealth landed in your mailbox, the agency could not confirm your eligibility from its own records and needs you to complete the MassHealth annual eligibility renewal form inside. You have 45 days from the date printed on the enclosed notice to review the pre-filled form, correct anything that has changed, and return it online, by mail, or by fax. Miss that deadline and your coverage can end.
The form you received depends on your age. Members under 65 get a version built on the standard ACA-3 application. Members 65 and older get the Senior Renewal Application, which also asks about assets. Either way, the fastest way to submit is online.
What’s in the Blue Envelope
The packet runs about 56 pages, roughly 40 of which are the actual form. It arrives pre-populated with the information MassHealth had on file the last time it confirmed your eligibility. Your job is to read every pre-filled field, fix anything out of date, and fill in what’s missing.
The deadline is printed on the notice inside. You have 45 days from that date. If the envelope never showed up or was lost, request a replacement by calling MassHealth at (800) 841-2900 (TDD/TTY: 711), or start your renewal through the online portal. Don’t wait until the deadline is close; gaps in coverage take time to fix.
Documents to Gather Before You Start
Pull everything together before you sit down with the form. What you need depends on which version you received.
If You’re Under 65
This form focuses on income, household composition, and access to other insurance. Have ready:
- Social Security numbers, addresses, and dates of birth for every household member on the form.
- Pay stubs or wage statements from the last four weeks showing gross pay for each working household member.
- Your most recent federal tax return with Schedule C if anyone is self-employed, showing net profit or loss.
- Award letters or statements for Social Security, unemployment, pensions, or other unearned income.
- Your most recent IRS Form 1040, which shows who you claimed as dependents. MassHealth uses this to define your household.
- Details about any employer-sponsored insurance available to household members, plus notes on any recent household changes such as a pregnancy or a birth.
Eligibility for this group is calculated using modified adjusted gross income (MAGI), which starts from line 11 of your Form 1040 and adds back items like tax-exempt interest and non-taxable Social Security benefits.
If You’re 65 or Older
The Senior Renewal Application (formally the MassHealth Renewal Application for Certain Seniors Living in the Community) asks for the income documents above plus financial records, because eligibility for this group includes an asset test. Also gather:
- Recent statements for all checking, savings, and investment accounts.
- Life insurance policy documents showing face value and any cash surrender value.
- Deeds or tax assessments for any real estate you own beyond your primary home.
- Documentation of any irrevocable burial funds or prepaid funeral plans.

Online submission is the quickest option and gives you an instant confirmation number.
Under 65

If you have an account but forgot your credentials, the site lets you reset your username and password. Once you’re in, the renewal appears with your pre-filled information. Work through each screen, update anything that’s changed, and submit. On the attestation page you provide an electronic signature, and a confirmation number appears immediately.1Mass.gov. Renew Your MassHealth Coverage
65 and Older
If your renewal notice includes an e-Submission number, complete the Senior Renewal Application at the MassHealth eSubmission portal (mhesubmission.ehs.mass.gov). Enter the e-Submission number to open your form, make your updates, and submit.1Mass.gov. Renew Your MassHealth Coverage If your notice doesn’t include an e-Submission number, you’ll need to submit on paper.
Submitting on Paper
If you’d rather use paper or don’t have online access, three options work. Whichever you choose, keep a full photocopy of what you send.
- Mail your signed form and supporting documents to Health Insurance Processing Center, P.O. Box 4405, Taunton, MA 02780.1Mass.gov. Renew Your MassHealth Coverage
- Fax everything to (857) 323-8300. The transmission receipt is your proof of submission.2Mass.gov. Health Coverage Mail/Fax Cover Sheet
- Drop it off in person at a MassHealth Enrollment Center during business hours. Enrollment centers accept in-person forms but don’t process mailed applications, so don’t send your packet to a local office.
Older MassHealth materials listed a P.O. Box in Charlestown and a different fax number. The Taunton address and (857) 323-8300 fax above are the current ones on the official page. Follow whatever specific instructions came with your notice, since the agency updates its processing locations from time to time.
If Someone Else Needs to Handle It
You can designate an authorized representative by completing the Authorized Representative Designation Form on mass.gov (available in PDF, Word, and Adobe Sign formats).3Mass.gov. Authorized Representative Designation Form Both you and the representative must sign, and the form has to be submitted with your renewal for the designation to take effect.
Once designated, that person can complete and sign your renewal, receive MassHealth notices (which may include health and financial information), and act on your behalf with the agency, including at an appeal hearing.4Mass.gov. 130 CMR 501.000 – MassHealth General Policies If a court-appointed guardian or someone with power of attorney is handling the renewal, include a copy of the legal documents.
Parents or legal guardians sign for household members under 18. If you only want someone to receive your mail but not sign or discuss case details, the form lets you set that narrower scope.
What Happens After You Submit
MassHealth checks the information you provided against its electronic data sources and mails a written notice confirming the submission is under review. If everything matches, you’ll receive a formal Eligibility Determination Notice and your coverage continues.
If something is missing or doesn’t line up, the agency sends a Request for Information (RFI) specifying what it needs. You have 90 days to respond.5Massachusetts Health Connector. MassHealth Health Connector Webinar That’s a generous window, but responding quickly keeps your coverage from slipping and spares you a last-minute document hunt.
If you don’t respond to an RFI or don’t return the renewal by the deadline, MassHealth can end your coverage. The agency must send a termination notice first, and that notice starts the clock on your right to appeal.
If You Miss the Deadline or Get Terminated
Losing coverage over a missed renewal isn’t permanent. You can reapply at any time with a new application, and there’s no waiting period. But medical expenses that fall between the termination date and the approval of your new application won’t be covered.
If you think the termination was wrong, say you sent your renewal on time and MassHealth has no record of it, you can request a fair hearing. The Board of Hearings must receive your signed request within 60 calendar days of the date you received the termination notice.6Mass.gov. How to Appeal a MassHealth Decision You can also ask that your coverage continue while the appeal is pending, which avoids a gap.
To file, complete the Fair Hearing Request Form on mass.gov and submit it within that 60-day window.7Commonwealth of Massachusetts Executive Office of Health and Human Services. Fair Hearing Request Form The form asks you to explain why you disagree with the decision and what outcome you want. You can represent yourself, bring a lawyer, or send your authorized representative. If the hearing officer finds MassHealth made a mistake, the agency has to correct the decision and restore any benefits you lost.
One Change on the Horizon
The annual renewal you’re doing now still applies to every MassHealth member for the 2026 cycle. Beginning with renewals scheduled on or after January 1, 2027, most adults enrolled through the Medicaid expansion group will need to complete redeterminations every six months instead of annually, under Section 71107 of the Working Families Tax Cut Act.8Centers for Medicare & Medicaid Services. Implementation of Eligibility Redeterminations, Section 71107 of the Working Families Tax Cut Legislation If you’re in that group, keep your income documents organized so the switch is easier when it arrives.
