On July 1, 2024, the program that paid for almost 800,000 New Mexicans’ Medicaid coverage changed its name. “Centennial Care” — the managed-care brand New Mexico had used since 2014 — became “Turquoise Care.” Most enrollees noticed only that their member cards got replaced and the website looked different. But underneath the rebrand was a substantive restructure of long-term services and supports, the home-care benefit, and most consequentially for the state’s tribal populations, the way Medicaid coordinates with Indian Health Service and Tribal 638 facilities.1

New Mexico is, by population share, the most American Indian state in the country: roughly 12% of residents are members of one of the 23 federally-recognized tribes in NM, including the Navajo Nation, the 19 Pueblos, and the Jicarilla and Mescalero Apache. For an adult child supporting a parent who lives on tribal land — where IHS provides primary medical care, state Medicaid may or may not be in the picture, and the tribal long-term-care system layers on top — the Turquoise Care transition is the most consequential policy change to engage with. This piece walks through what changed in the rebrand, what stayed the same, and the four planning questions families with parents on tribal lands should work through in 2026.

What changed in the transition

The headline rebrand was cosmetic, but the underlying waiver renewal made four substantive policy moves:

1. The Community Benefit replaced CLTSS

Under Centennial Care, the home- and community-based LTSS program was called Coordinated Long-Term Services and Supports. Turquoise Care renamed it the Community Benefit and reworked the menu of services. The biggest practical change for caregivers is in participant-directed services: the new framework expanded who can be paid as a family caregiver, increased the allowable hours, and contracted with a single financial management services (FMS) entity to handle payroll for family caregivers across all four MCOs.4

2. The MCO contracts were re-bid

The four-MCO structure carried forward (BCBSNM, Presbyterian, United, Molina), but the contract terms tightened on care coordination, prior authorization turnaround, and provider-network adequacy requirements.2 Members were allowed a 90-day window after July 1, 2024 to change MCOs without restriction; the standard annual open-enrollment window resumed thereafter.

3. The tribal-overlay pathway was formalized

For Native American Medicaid members, Turquoise Care formalized the option to enroll with the Native American Care Coordination unit rather than a standard MCO. The NACC unit, which sits within HSD, coordinates with IHS and Tribal 638 health programs in a way that’s conceptually similar to MCO care management but culturally and procedurally adapted. The option existed informally under Centennial Care; Turquoise Care made it an explicit enrollment choice with documented procedures.

4. The behavioral-health carve-out moved

Behavioral-health services that had been carved out into a separate statewide entity under earlier Centennial Care phases are now integrated back into MCO benefits under Turquoise Care. For families dealing with a parent’s dementia diagnosis or post-stroke depression, this consolidates care management within a single MCO rather than spreading it across multiple administrative entities.

The IHS / Tribal LTC interaction

This is the part of New Mexico Medicaid that almost no general-purpose guide covers correctly, and it’s the part most consequential for the roughly 12% of NM residents who are tribal members.

IHS is the federal agency that provides health care to members of federally-recognized tribes. IHS facilities (and Tribal 638 facilities, which are tribally-operated under self-determination contracts) deliver primary medical care, hospital care, and a varying menu of specialty services. For long-term services and supports — nursing home care, assisted living, in-home personal care, adult day health — the menu is much thinner. Most tribal members who need LTSS eventually route into the state Medicaid system for those services even when their primary medical care remains IHS.

The fiscal mechanism behind this is the 100% FMAP rule: when a tribal Medicaid member receives a service at an IHS or Tribal 638 facility, the federal government reimburses the state for 100% of the cost.3The state has no fiscal reason to push tribal members out of IHS care; in fact the opposite. The challenge isn’t fiscal — it’s coordination, eligibility documentation, and the practical reality that IHS facilities in the Four Corners region are often hours from the nearest state- contracted nursing facility.

The four planning questions for tribal-land families

For an adult child supporting a parent who lives on tribal land in New Mexico, the four questions worth working through with a Medicaid-experienced advocate are:

  1. Is the parent enrolled with the Native American Care Coordination unit or with a standard MCO? The choice has material consequences for how care coordination works, who the case manager is, and how referrals to specialty care outside the IHS service array get processed. NACC is generally the better fit for parents whose primary medical home is IHS; a standard MCO may be the better fit when the parent lives primarily off-reservation or routinely uses non-IHS providers.
  2. Where does LTSS come from? IHS does not generally provide custodial nursing-home care, in-home personal care, or adult day health. These services come through the state Medicaid Community Benefit program, regardless of whether the parent uses IHS for primary care. The Community Benefit application is filed with HSD; eligibility is determined under state rules; the service plan is built through the MCO or NACC case manager.
  3. Is the family caregiver paid through the Community Benefit?Under Turquoise Care’s expanded participant-directed model, an adult child can be paid to provide personal care to a parent who qualifies for the Community Benefit. The payment rate varies by region and authorized hours; for tribal-land families this is often the most accessible LTSS option given the geographic isolation of many communities.4
  4. What about asset and look-back planning? New Mexico applies the standard 60-month federal look-back to Medicaid LTSS applications.5 Tribal trust property generally is not a countable Medicaid asset (it’s held in trust by the federal government), and certain per-capita distributions from gaming compacts are excluded under federal Medicaid rules. The interaction is specific to each tribe and to the parent’s own asset picture; an attorney familiar with both NM Medicaid and federal Indian law is the right consultation here.

What the 2024 transition didn’t change

Three things to watch that didn’t change in the Turquoise Care transition, in case the rebranding gives a misleading sense of broader reform:

The bottom line

The Turquoise Care transition was, on balance, a modest-positive change for New Mexico Medicaid LTSS participants. The participant-directed care expansion and the formalized tribal-overlay pathway are real improvements. The MCO recontracting tightened some accountability provisions without dislocating the existing network. The behavioral-health re-integration is the change most likely to be revisited in 2029.

For families with parents on tribal lands, the most important practical step is to confirm enrollment with either the NACC unit or a chosen MCO, understand which LTSS services come through which path, and — if family caregiving is in the picture — pursue the Community Benefit’s participant-directed option deliberately rather than letting it default. The system rewards documentation and planning; it does poorly when families navigate it for the first time in a crisis.6
