New Mexico Medicaid Costs Rose as Enrollment Fell, LFC Analysts Find
New Mexico Medicaid spending more than doubled through fiscal 2026 even as enrollment fell after its fiscal 2023 peak, putting attention on per-member costs, hospital payments and managed-care accountability.
New Mexico Medicaid spending more than doubled from fiscal year 2017 through fiscal year 2026 even as enrollment fell by more than one-fifth after its fiscal 2023 peak, according to Legislative Finance Committee analysis. The finding shifts the central budget question from how many people are enrolled to how much care costs for each person who remains covered.
The LFC presented the cost-driver analysis in a June 2026 review included in the committee’s July materials. A separate overview of New Mexico’s health care system was presented July 22, 2026. Together, the documents describe a program with major consequences for state and federal budgets, hospitals, managed-care companies and hundreds of thousands of residents.
Per-member costs drove about $6.7 billion in growth
LFC estimated that rising costs per member added approximately $6.7 billion to Medicaid spending between FY2017 and FY2026. The decline in enrollment would have reduced spending by roughly $600 million if costs per member had remained unchanged. The resulting net increase was about $6.2 billion.
The analysis does not say enrollment fell continuously throughout the period. It compares spending through FY2026 and identifies a decline after the FY2023 peak, when temporary federal pandemic-era rules limited disenrollment. KUNM reported that enrollment reached about 992,000 during the 2023 budget year and later fell after people were required to complete renewal paperwork. About 818,000 New Mexicans remained enrolled as of June, according to Health Care Authority data cited in the report.
LFC says the remaining population is sicker on average, which raises costs even as the number of covered people declines. Long-term services and supports are particularly expensive: the presentation shows managed-care spending for that population rising from $1,916 per member per month in FY2020 to $3,169 in a preliminary FY2026 figure.
Hospital payments and prescription drugs add pressure
Hospital reimbursement is one of the largest identified drivers. New Mexico’s Healthcare Delivery and Access Act created directed payments intended to raise Medicaid hospital reimbursement toward average commercial rates. The LFC presentation identifies approximately $1.9 billion in directed payments above base Medicaid hospital payments in FY2024, with about 75% funded through federal dollars. Its ranking of recurring cost drivers estimates the HDAA’s annual impact at roughly $1.36 billion to $1.46 billion.
The presentation also points to specialty drugs and GLP-1 medicines, higher wages for medical and behavioral-health workers, general medical inflation and increased use of care by a higher-acuity population. In the broader commercial market, LFC found that gross drug costs doubled between 2017 and 2024, while net pharmacy spending rose from 15% to 20% of claims.
Those pressures matter beyond Medicaid. The July 22 LFC overview said government-subsidized coverage accounts for about 75% of all coverage in New Mexico, although people with more than one type of coverage mean the categories do not add to 100%. Medicaid alone accounts for about 32% of coverage in the presentation’s payer mix.
Managed-care payments raise an accountability question
New Mexico pays managed-care organizations a fixed amount per member, known as capitation. LFC reported that total managed-care cost per member per month rose from $576 in FY2020 to $735 in FY2025, with a preliminary FY2026 figure of $883. The FY2026 number is based on a partial year and is not final.
Turquoise Care contracts require plans to meet a 90% Medicaid medical-loss-ratio floor. LFC describes that floor as a requirement that at least 90% of the adjusted premium denominator be represented by medical claims; if a plan falls below the floor, it must return the difference. The Medicaid measure is distinct from the commercial-market loss ratios discussed elsewhere in the presentation.
LFC cautioned that the measure tracks claims spending, not whether members received timely appointments or experienced better health outcomes. Meeting the floor can show that money was directed to claims, but it does not by itself establish that access improved or that patients became healthier.
The contracts also contain performance withholds and gain-and-loss provisions. LFC says up to 5% of capitation can be tied to separate delivery-system and quality measures, while the gain-and-loss corridor divides financial risk between managed-care plans and the state. Under the contract mechanics described in the presentation, plans retain most gains within a specified corridor, while the state absorbs a larger share of losses beyond certain thresholds. That is an analysis of contract terms, not a finding that a plan violated its contract or acted unlawfully.
What residents should watch next
For residents, the immediate issue is not a change in Medicaid eligibility announced by the LFC presentations. The documents are legislative analysis and oversight materials, not a new law, rule or final policy decision.
Future federal changes remain important. KUNM reported that new work requirements and more frequent eligibility checks are expected to take effect later, and that the New Mexico Health Care Authority is preparing for them. Those changes should not be treated as currently implemented in the state.
The next accountability questions are whether state officials will publish clearer measures of appointment access and health outcomes, whether lawmakers revisit managed-care risk-sharing terms, and how the state plans for future changes in federal funding. Enrollment totals, provider participation, behavioral-health access, hospital payment policy and managed-care performance reports will show whether higher spending is translating into better care.
