Louisiana paid $1.23 billion for Medicaid care that never happened

The easy explanation for a Medicaid beneficiary who files no claims for years is that they're healthy and simply don't need care.▸ The Louisiana Legislative Auditor -- the state legislature's independent watchdog over how agencies spend public money -- tested that explanation⧉ against the state's own Medicaid data and found it doesn't survive contact with the numbers. Between January 2018 and December 2024, the Louisiana Department of Health (LDH) paid its six managed care organizations (MCOs) -- private insurers LDH hires, and pays a flat monthly fee per enrollee, to run the state's Medicaid coverage -- $1,233,547,133 to manage the care of 50,299 beneficiaries who appear to have been continuously enrolled for 36 to 84 months, three to seven years, without a single recorded service. That flat fee is the mechanism: an MCO gets paid the same whether an enrollee sees a doctor or not, so a beneficiary nobody is watching costs the state exactly as much as one getting full care. LDH itself has never run the analysis that would catch this. The auditor had to build it from scratch, for the second time in eighteen months.

Some of the 50,299 probably are exactly what the healthy-and-uninsured-elsewhere theory predicts: 9,927 of them (19.7%)⧉ carried third-party private or Medicare coverage in every month the auditor checked, and a further chunk are young adults in the Medicaid Expansion group who may simply not have gotten sick.▸ But that theory gets harder to credit as the population narrows.

6,338 of the flagged beneficiaries -- 12.6% -- are enrolled as aged, blind, or disabled⧉, categories the auditor specifically flags as unlikely to go years without needing any medical services at all; LDH paid $245,505,419 to manage their care regardless.▸ Another 11,127 (22.1%) live in a rural parish⧉, where the auditor notes access to a provider, not health, may be the real explanation. And 4,526 (9.0%)⧉ are on the rolls only because the Social Security Administration deemed them eligible for Supplemental Security Income -- LDH certifies that group automatically, at application and at every renewal, without asking a single follow-up question.

Louisiana's Medicaid MCOs are paid a fixed monthly premium -- a per-member-per-month (PMPM) rate -- to manage each enrollee's care, whether or not that person files a single claim.▸ That structure means the $1.23 billion isn't money that vanished; it's money the six insurers kept regardless of what they did with it. United Healthcare Community Plan collected $299,267,652⧉ for 20,192 beneficiaries who filed nothing, the largest single share of the six, trailed closely by Healthy Blue at $286,295,532 and Louisiana Healthcare Connections at $278,335,722. Every MCO's contract requires it to monitor and manage enrollee care; none of the six, per the auditor, reported these no-service patterns back to LDH on its own.

Federal rule already sets the baseline LDH is supposed to meet: 42 CFR 438.340 requires the agency to run a written quality strategy assessing exactly this -- whether MCO-managed beneficiaries are actually getting care.▸ This is the second time the Legislative Auditor has had to build that missing analysis rather than review one LDH already produced. A May 2024 report first found the same pattern⧉ at a shorter enrollment window and recommended LDH start running it routinely. As of March 2025 -- ten months later -- LDH told auditors it still had not implemented the recommendation⧉, saying it was still developing a process to check twice a year. LDH's stated position, per the auditor, is that identifying these beneficiaries is the MCOs' job. The MCOs told the auditor the opposite: they already run this kind of claims analysis internally for their own outreach, but consider it "an eligibility issue" that belongs to LDH -- and said LDH had never asked them for the results before this review. Neither side had been checking, and the gap between them is where $1.23 billion sat unexamined.

The auditor's own follow-up work shows the flag doesn't fix the problem by itself.▸ Of the 50,299 people identified, 23,123 (46.0%) were still enrolled in Louisiana Medicaid as of June 2025⧉ -- found, but not yet acted on. A separate companion audit adds one more data point against the benign explanation: 161 of the flagged beneficiaries had already been identified as deceased⧉ in the Legislative Auditor's own August 2025 report on deceased Medicaid beneficiaries -- a small slice of the 50,299, but proof that at least some of this population isn't healthy and elsewhere. They're gone, and Louisiana was still paying to manage their care.
