Medicaid enrollment growth during the COVID pandemic
The COVID pandemic pushed enrollment quite a bit higher: By November 2021, enrollment in New Mexico Medicaid was 88% higher than it had been in late 2013. And by the end of 2021, New Mexico Medicaid enrollment had grown to 954,491, including nearly 300,000 people enrolled in Medicaid expansion under the ACA.
Enrollment growth during the pandemic was driven primarily by the Families First Coronavirus Response Act, which provides states with additional federal Medicaid funding, but on the condition that coverage not be terminated for any enrollees during the public health emergency period. So the normal periodic eligibility redeterminations have been paused since March 2020.
Nationwide, millions of people could lose their Medicaid coverage once the public health emergency period ends. New Mexico officials estimate that about 85,000 New Mexico Medicaid enrollees will be ineligible for Medicaid at that point, and are working to ensure that these individuals do not become uninsured. Roughly half are expected to be eligible for employer-sponsored health insurance, while the other half will be eligible for subsidized coverage in the New Mexico marketplace/exchange.
Accepting Medicaid expansion
Before 2014, Medicaid was generally only available for the aged, blind, disabled, pregnant women, children, and some low-income parents. But the expanded guidelines provide coverage for adults 19-64 with household incomes up to 133% of poverty (138% counting the five percent income disregard).
On January 9, 2013, then-Governor Susana Martinez announced that New Mexico would participate in Medicaid expansion, describing expansion as “what is best for New Mexicans.” At the time, Martinez was only the second Republican governor to accept Medicaid expansion.
New Mexico’s Medicaid program was renamed Centennial Care starting January 1, 2014. Most of the previously enrolled members of New Mexico Medicaid were eligible to remain covered under Centennial Care, but the newly expanded guidelines meant that many more people were also eligible to join the program in 2014.
Centennial Care was designed to be a modernized overhaul of many aspects of the legacy New Mexico Medicaid system. The new program aims to teach enrollees to become better healthcare consumers and take a more active role in their own health. It’s also focused on integrated care and better case management for the sickest members. In addition, it’s transitioning away from a fee-for-service model towards a payment system that rewards providers based on outcomes.

Centennial Care insurers: Blue Cross Blue Shield of New Mexico, Presbyterian, and Western Sky
Under a Medicaid managed care model like Centennial Care, the state contracts with private insurers rather than directly providing Medicaid coverage to residents. The state pays the insurers, and the insurers provide Medicaid benefits to enrollees. As of 2022, there are three insurers in the Centennial Care Medicaid managed care program: Blue Cross Blue Shield of New Mexico, Presbyterian, and Western Sky Community Care.
Four insurers had Centennial Care contracts through the end of 2018: Blue Cross Blue Shield of New Mexico, Molina, Presbyterian, and UnitedHealthcare. But Molina and UnitedHealthcare were not selected to continue to provide Medicaid managed care services in New Mexico starting in 2019. Presbyterian and Blue Cross Blue Shield had their contracts renewed, and Western Sky Community Care also won a contract with Centennial Care. Those three insurers are continuing to provide Medicaid managed care in 2020.
Molina filed a lawsuit against the state, alleging that Western Sky’s bid win may have been tainted by an official with a conflict of interest, but a judge threw out the lawsuit. Molina initially said that if they couldn’t remain in the Centennial Care program, they may leave the state entirely (including the exchange market), because Medicaid managed care is the “most significant portion” of Molina’s business in New Mexico. But that did not come to pass, and Molina still offers coverage in the New Mexico exchange.
New Mexico Medicaid enrollment
From the fall of 2013 through July 2016, total enrollment in New Mexico Medicaid increased by 303,355 people, or 66%, and reached 761,033. As was the case in most states, enrollment grew sharply in 2014 and 2015, but had mostly leveled off by 2016. By the end of 2017, New Mexico Medicaid enrollment had dropped slightly, and total enrollment growth stood at 63%
But as of November 2021, total New Mexico Medicaid and CHIP enrollment had grown by another 100,000 people, and stood at 861,297. This was an 88% increase over 2013 (pre-ACA expansion) levels. This large jump in enrollment since 2016 is mostly due to the COVID-19 pandemic and the Families First Coronavirus Response Act, which provides additional federal Medicaid funding as long as states do not disenroll anyone from Medicaid during the COVID public health emergency.
According to U.S. Census data, the uninsured rate in New Mexico fell from 19.6% in 2010 to 10% in 2019 — a drop of almost 50%, versus the national average drop of about 40%.
New Mexico opted for state subsidies instead of Medicaid buy-in
In 2017, Nevada lawmakers passed legislation that would have allowed for Medicaid buy-in, but Governor Brian Sandoval vetoed it. If he had approved it, New Mexico would have been the first state with a Medicaid buy-in program.
U.S. Representative, Ben Ray Lujan, who represents New Mexico’s 3rd Congressional District, supports the idea of Medicaid buy-in. And Governor Michelle Lujan Grisham, who was a U.S. Representative until winning her 2018 gubernatorial race, introduced legislation at the federal level in 2017 that would have allowed people to buy into Medicaid. The Health Care Choices and Affordability Act did not advance at the federal level, but creating a Medicaid buy-in program may end up being more feasible at the state level.
In early 2018, lawmakers in New Mexico passed two legislative memorials (SM3 and HM9) calling for a cost analysis of a potential Medicaid buy-in program in New Mexico. Lawmakers wanted to get a good idea of the costs of allowing New Mexico residents who aren’t eligible for Medicaid to purchase Medicaid instead of obtaining private coverage or remaining uninsured. They also wanted feedback from stakeholders in terms of the implications and pros and cons of a Medicaid buy-in program in New Mexico.
New Mexico reconsidered the buy-in program in 2019, but it didn’t pass. Instead, the state pivoted to focus on the idea of using state funds to provide additional subsidies for people who buy their own health insurance. In 2021, the state enacted legislation to reinstate the health insurance tax in NM (at the state level rather than the federal level) and use the money to create a Health Care Affordability Fund
