How to Join a Pooled Income Trust in New York

Enrollment has four real steps: sign and notarize a Joinder Agreement with a non-profit trust organization, submit that agreement plus a disability-determination request to your local Department of Social Services, provide medical evidence if the state's disability review team asks for it, and confirm the Medicaid rebudgeting notice uses the correct effective date. Most of the paperwork is document-gathering, not decision-making — this page lists exactly what's needed at each step, in the order it actually happens.

Before you start

Pick a trust organization first (see the list on the Pooled Income Trust overview) — you'll need their specific Joinder Agreement form and their current enrollment fee before step one. Every organization runs its own version of this process on the same underlying legal structure, so confirm the details below against the paperwork your chosen trust actually sends you.

The four steps

1. Enroll with a trust organization

   Submit a signed, notarized Joinder Agreement to the non-profit trust organization, along with a copy of the applicant's Social Security award letter and the initial deposit (a cashier's check, certified check, or money order — the trust organization will specify the guaranteed-funds format it requires).

2. Submit the trust documents to Medicaid, with disability proof

   Send your local Department of Social Services the Master Trust Agreement, the signed Joinder Agreement, verification of your monthly deposits, the trust's acceptance letter, Form MAP-751W (if you're already Medicaid-enrolled), the Disability Determination Request (Form MAP-3177), and a HIPAA authorization (OCA Form 960) — with a cover letter asking DSS to eliminate the spend-down and, where applicable, enroll you in a Medicare Savings Program.

3. Provide medical evidence if the state requests it

   If the NYS Disability Review Team needs more than the initial MAP-3177 to confirm disability status, they will request the Medical Report for Determination of Disability (DOH-5143), a year of medical records, the Disability Questionnaire (DOH-5139), and a state HIPAA form (DOH-5173).

4. Confirm the rebudgeting notice is correct

   When Medicaid sends the rebudgeting notice, check that the effective date matches the month you first began depositing your excess income into the trust — not a later month. An incorrect effective date is a real, documented error worth catching, and the fix is requesting a Fair Hearing if DSS won't correct it directly.

The documents, at a glance

• Joinder Agreement — Notarized agreement with the trust organization — the core enrollment document.
• MAP-751W — Filed if the applicant is already enrolled in Medicaid.
• MAP-3177 — Disability Determination Request — submitted together with the trust documents.
• OCA Form 960 — HIPAA authorization.
• DOH-5143 — Medical Report for Determination of Disability (replaces the older DSS-486T).
• DOH-5139 — Disability Questionnaire (replaces the older DSS-1151).
• DOH-5173 — State HIPAA authorization form.

If you're using Power of Attorney

A prior requirement for a Statutory Gift Rider when using POA to establish a pooled trust was eliminated by GIS 20 MA/03 (confirms a Statutory Gift Rider is not required to use a Power of Attorney to establish a pooled trust). If a trust organization or caseworker tells you otherwise, that's worth double-checking against current guidance directly rather than assuming the older requirement still applies.
