To apply for New Mexico Medicaid long-term care, start at the YesNM portal (yes.state.nm.us) or call the Income Support Division at 1-800-283-4465. If your gross income exceeds $2,982 per month, you must establish a Miller Trust before you submit the application, or it will be denied. This guide walks through every channel, the trust gate, the documents, the 45-day clock, and what to do if you are denied.

How to Apply for New Mexico Medicaid: Which Application You Need

New Mexico Medicaid runs under the name Centennial Care and is administered by the New Mexico Health Care Authority, formerly the Human Services Department. Its Income Support Division (ISD) determines eligibility for aged, blind, and disabled (ABD) residents and for anyone of any age who needs long-term care.

The "apply online" route most families find first is built for the MAGI population (children, parents, pregnant individuals, and expansion adults). A senior applying for nursing-facility or home- and community-based services (HCBS) coverage applies on the aged, blind, and disabled track, where two extra gates sit in front of the decision that the MAGI flow never mentions:

  • A financial gate. If gross monthly income is over the cap, a Miller Trust must already exist when you file.
  • A clinical gate. Long-term-care Medicaid requires a finding of nursing-facility level of care (NFLOC), a clinical determination assessed against activities of daily living, skilled-nursing needs, and cognitive impairment. Each state sets its own instrument, and the assessment runs alongside the financial review.

Getting on the right track from the start is the single biggest thing you can do to avoid a stalled or denied application.

Before You Apply: The Miller Trust Gate

New Mexico is an income-cap state. It does not offer a medically needy spend-down pathway for nursing-facility or HCBS-waiver applicants. If your gross monthly income exceeds $2,982, you do not simply pay the difference. You are ineligible unless you first establish a Qualified Income Trust, which New Mexico officially calls an Income Diversion Trust and which most families know as a Miller Trust.

A Miller Trust is authorized under federal law (Section 1917(d)(4)(B) of the Social Security Act) for applicants whose income exceeds the state's cap. The $2,982 cap is the Special Income Level: 300% of the 2026 Supplemental Security Income (SSI) Federal Benefit Rate of $994.

Mechanically, only the applicant's own income may be deposited into the trust; resources and savings cannot be used to fund it. The trust pays toward the cost of care each month, and Medicaid covers the remainder. Key points for New Mexico:

If your income is at or below $2,982, you can skip this step and apply directly.

How to Apply for New Mexico Medicaid

The Income Support Division takes applications through two main channels: online through YesNM or by phone.

Online Through YesNM

The YesNM portal (yes.state.nm.us) is the fastest way to apply. You can start an application, upload documents, and track your case status from one account.

1
Step 1

Create your YesNM account

Go to the YesNM portal (yes.state.nm.us) and create an account or log in.

2
Step 2

Start a Medicaid application

Select "Apply for Benefits" and choose Medicaid.

3
Step 3

Complete the application

It covers household composition, income, assets, and care needs. Have your documents ready before you start (see the documents section below).

4
Step 4

Upload your supporting documents

Attach them directly through the portal. This is the fastest way to satisfy the verification step.

5
Step 5

Submit and save your case number

You will receive a confirmation and a case number when the application is filed.

After you submit, log back in periodically to check whether ISD has requested additional documents. Requests often appear in the portal before the paper notice arrives.

By Phone or In Person Through the Income Support Division

Call 1-800-283-4465 to apply with an ISD caseworker who takes the application over the phone, or apply in person at a local ISD field office. Phone and in-person applications work the same way as the online one, but you will still need to submit scanned or paper documents. Find your nearest field office through the New Mexico Health Care Authority.

Applying on Behalf of Someone Else

If the applicant has dementia or cannot manage the process, an authorized representative can apply for them. An agent under a valid power of attorney, a legal guardian, or a representative the applicant designates in writing can file the application, submit documents, and speak with ISD. Have the power-of-attorney or guardianship paperwork ready, because ISD will ask for proof of the representative's authority.

The Documents You Will Need

Gather these before you apply. Missing documents are the most common reason applications stall.

Identity and residency:

  • Social Security card
  • U.S. passport, birth certificate, or Certificate of Naturalization
  • New Mexico driver's license or state ID
  • Proof of New Mexico residency (utility bill, lease, or similar)

Income:

  • Social Security award letter or SSA-1099
  • Pension and annuity statements
  • Any other monthly income documentation

Assets and financial accounts:

  • Bank statements for all checking and savings accounts. For nursing-facility or HCBS-waiver applications, ISD reviews up to 60 months (five years) of account history to apply the look-back rules.
  • Statements for retirement accounts, CDs, and investment accounts
  • Life insurance policies (cash surrender value, if any)
  • Vehicle title or registration

Property:

For Miller Trust applicants:

  • A copy of the executed trust document, signed by the grantor and trustee and notarized

Medical:

  • Medicare card (if applicable)
  • Health insurance cards
  • Medical bills if you are documenting care need or unreimbursed expenses

Spousal Protections

If one spouse applies for nursing-facility or HCBS-waiver Medicaid while the other remains at home, New Mexico follows federal spousal impoverishment rules under 42 USC 1396r-5.

  • Community Spouse Resource Allowance (CSRA): the at-home spouse may keep between $32,532 and $162,660 in countable assets, depending on the couple's total countable resources at the time of application.
  • Minimum Monthly Maintenance Needs Allowance (MMMNA): the at-home spouse is allowed a protected monthly income of at least $2,705.00 (effective 7/1/2026) and up to $4,066.50 (effective 1/1/2026). If the at-home spouse's own income falls short, part of the institutionalized spouse's income can be redirected to make up the difference.
  • Personal Needs Allowance: the nursing-facility resident keeps $97 per month for personal expenses, among the highest figures in the country.

The 60-Month Look-Back

When you apply for nursing-facility or HCBS-waiver Medicaid, ISD reviews the past 60 months (five years) of financial records for gifts or asset transfers made below fair market value. If a disqualifying transfer is found, ISD calculates a penalty period during which Medicaid will not pay for care, by dividing the transferred value by the state's average monthly private-pay nursing-facility cost.

Some transfers do not trigger a penalty. The federal exceptions include transfers between spouses and a transfer of the home to a son or daughter who lived in the home for at least two years immediately before the parent was institutionalized and provided care that let the parent stay at home (the caregiver-child exception under 42 USC 1396p(c)(2)(A)(iv)). Transfers to certain disabled individuals are also exempt under 42 USC 1396p(c)(2).

If you made any transfers in the past five years, consult an elder law attorney before applying. The timing and structuring of the application can affect whether a penalty applies.

How Long It Takes, and Why the Date You Apply Matters

Federal law caps how long the agency may take. Under 42 CFR 435.912, ISD must decide an application within 45 days, or within 90 days when the application is based on disability. Those are ceilings, not promises. Long-term-care determinations often run longer because they pair the financial review with a clinical level-of-care assessment, so the practical advice is to respond to every document request immediately to keep your case moving.

The date you apply also sets a coverage window. Federal law requires retroactive eligibility: once you are approved, coverage reaches back to covered services furnished in or after the third month before the month you applied, as long as you would have been eligible then. That is why families with bills already piling up should not delay filing.

One forward change is worth knowing. Under Public Law 119-21, for applications filed on or after January 1, 2027, the retroactive window shrinks to two months before the application month for most enrollees (and one month for the Medicaid expansion adult group). If care has already started, applying sooner rather than later protects more of the back-coverage.

If Your Application Is Denied

You have up to 90 days from the date of a denial notice to request a fair hearing. To request one, contact the Income Support Division by mail, in person at an ISD office, or by phone at 1-800-283-4465.

Common reasons for denial, and what to do:

A separate rule helps current beneficiaries facing a termination or reduction: federal "aid paid pending" continues benefits during an appeal only when the hearing is requested before the action's effective date. At the hearing, a hearing officer reviews your case and issues a written decision; if you disagree, you can appeal to district court.

You do not have to navigate the application alone. Several New Mexico programs offer free, one-on-one help with Medicaid applications, the Miller Trust gate, and appeals.

Frequently Asked Questions

Can I apply for New Mexico Medicaid if my income is above $2,982 per month?

Yes, but you must set up a Miller Trust (Qualified Income Trust) before you submit the application. The trust redirects the income above $2,982 each month toward the cost of care. A Miller Trust is authorized under Section 1917(d)(4)(B) of the Social Security Act, and only the applicant's own income may go into it. An elder law attorney can prepare the trust document; once it is in place, you can apply through YesNM or by phone.

How long does it take to get a decision on a New Mexico Medicaid application?

Under 42 CFR 435.912, ISD must decide within 45 days, or within 90 days when the application is based on disability. Document verification is the most common source of delay, so respond immediately to any request from ISD and upload documents through YesNM to keep your case moving.

Does New Mexico's Medicaid look at my past bank accounts?

Yes. For nursing-facility and HCBS-waiver Medicaid, ISD reviews 60 months (five years) of financial records to check for gifts or below-market asset transfers. You will need to provide bank statements going back five years. If you made any transfers in that window, consult an elder law attorney before applying to understand whether a penalty period applies.

Does the date I apply affect my coverage?

Yes. Federal law requires retroactive eligibility, so once you are approved, coverage can reach back to covered services furnished in or after the third month before the month you applied, if you would have been eligible then. For applications filed on or after January 1, 2027, that window shrinks to two months for most enrollees under Public Law 119-21, so filing sooner protects more back-coverage.

Can someone apply for New Mexico Medicaid on a parent's behalf?

Yes. An authorized representative, such as an agent under a power of attorney, a legal guardian, or someone the applicant designates in writing, can file the application, upload documents, and speak with ISD. Have the power-of-attorney or guardianship paperwork ready, because ISD will ask for proof of the representative's authority before discussing the case.
