331 Fraud Cases. 2 Convictions. Is New Mexico Catching Medicaid Fraud?

In May, Vice President JD Vance gave all 50 states an ultimatum: fully comply with federal antifraud laws or risk losing federal Medicaid money. His White House fraud task force made Minnesota its poster child and named California, Illinois, New York, Maine and Colorado as states of concern.

New Mexico isn't on the list. Going by the federal government's own numbers, maybe it should be.

The money

New Mexico spent $10.47 billion on Medicaid in federal fiscal year 2025, according to the HHS Office of Inspector General. That's about $28.7 million a day.

No state covers a bigger share of its people. Legislative analysts have called it the largest Medicaid program per capita in the country. Among children, 57.3 percent of New Mexicans under 19 are covered by Medicaid or similar public insurance. In 28 of 33 counties, most kids are on it.

When this much money moves through one system, some of it gets stolen. That's true in every state. What matters is how much of it gets caught.

The funnel

Every state has a Medicaid Fraud Control Unit. In New Mexico, it sits in the Attorney General's office. The unit investigates providers who bill for care they never gave, pad their claims or pay kickbacks.

In FY2025, the New Mexico unit opened 331 fraud investigations. That's more than twice the national rate per dollar spent, so the unit is busy.

Here is where those cases ended up:

• 331 fraud investigations
• 7 fraud indictments
• 2 fraud convictions

That's 1 conviction for every 165 investigations. Nationally, about 1 in 15 fraud investigations ends in a conviction. New Mexico ranked 50th of 53 fraud units.

Next door, Arizona opened 121 fraud investigations and won 43 fraud convictions, about 1 in 3.

The four-hour year

New Mexico's fraud unit recovered $4.94 million in FY2025, counting criminal and civil cases together.

Stack that against daily spending ($28.7M/day) and a full year of recoveries equals about four hours of New Mexico Medicaid spending.

Put another way, for every $100 New Mexico spends on Medicaid, fraud enforcement brings back about 5 cents. The national average is 19 cents. Arizona gets back 22 cents and Texas 28.


Criminal recoveries, the money clawed back from people actually convicted, totaled $38,278 for the entire year. That's about the price of a new pickup truck, taken out of a $10.5 billion program.

The unit itself cost $4.33 million to run. It returned $1.14 for every dollar spent on it. Nationally, fraud units return $4.64.

The errors nobody calls fraud

A separate federal audit, the CMS error-rate study, estimates New Mexico made about $240 million in improper Medicaid payments, an error rate of 3.7 percent.

Not every improper payment is fraud. Many are paperwork failures. But the gap stands out: roughly $240 million in estimated bad payments against $4.9 million recovered by fraud enforcement.

It fits a pattern. In 2024, federal auditors found the state had failed to recoup $168.6 million it overpaid to its Medicaid managed-care companies. The state later covered that money in the budget instead of clawing it back. A 2019 federal review found the state wasn't independently checking the overpayment figures those companies reported. And in 2011, the Legislative Finance Committee called New Mexico's fraud oversight "fragmented" and said the state got a "poor return on its investment."

What happened next door

Arizona is the warning. Starting around 2019, fake sober-living homes recruited Native Americans, often straight off reservations, and billed Arizona Medicaid for treatment they never provided. Some billed more than $8,000 per patient per day. The losses are estimated at $2.8 billion. People died.

The same populations live on the New Mexico side of the line. McKinley, San Juan and Cibola counties combine heavy Medicaid enrollment with some of the highest poverty in the state. Child Medicaid coverage runs 77.7 percent in McKinley and 78.8 percent in Cibola.

Minnesota shows how fast it can happen. A housing program budgeted at about $2.5 million a year cost more than $104 million by 2024 before the state shut it down. Federal prosecutors have charged dozens of people in Minnesota autism and housing schemes.

Neither state caught its fraud early. Both were caught by outsiders.

What the numbers don't say

Low recoveries can mean two things: there's little fraud to find, or the state isn't finding it. The data alone can't prove which.

New Mexico isn't dead last on every measure. Oklahoma recovers less per dollar, and the median state isn't far ahead. One big case can swing a small state's totals from year to year.

New Mexico also has a history of getting this wrong in the other direction. In 2013, the state froze payments to 15 behavioral health providers over "credible allegations of fraud." The Attorney General later cleared them, and the state paid settlements.

But consider what New Mexico brings to the table: the largest per-capita program in America, a neighbor that just lost billions, documented failures to recover overpayments, and a fraud unit that turned 331 investigations into two convictions. Believing the problem is small takes a lot of faith.

The Vance task force is asking states to prove they're protecting Medicaid dollars. Going by the federal data, New Mexico would have a hard time making that case.
