Three States, One Leak: $876M in Medicaid Paid for the Ineligible

Between September 2025 and January 2026, three state audit offices published three separate examinations of three separate Medicaid managed-care programs -- and reached the same finding.▸ Kentucky paid MCOs $836,364,425.pdf) over 2019-2022 for 103,907 people concurrently enrolled in another state's Medicaid program. West Virginia paid $31.7 million⧉ for 94,214 incarcerated-individual cases and $770,016 more for 15,346 deceased-individual cases over the same four fiscal years. Maryland paid $7.8 million⧉ for 2,452 incarcerated enrollees -- a finding its auditors marked Repeated, because the preceding report had already flagged roughly $14 million of the same thing. The instrument differs by state; the mechanism does not: capitation is a fixed per-member-per-month premium, and once a person should have left the rolls, every additional month is money paid for coverage no one can use.

The three ledgers are independent.▸ Kentucky's Auditor of Public Accounts ran a 2025 special examination.pdf) using national T-MSIS enrollment data supplied through a partnership with HHS's Office of Inspector General, transmitted federally as report A-09-23-02005⧉ -- the first time the state could see its enrollees' simultaneous enrollment across 48 other states. West Virginia's Legislative Auditor matched Bureau for Medical Services capitation records against Division of Corrections and vital-statistics data⧉ in an audit that began in September 2022 and was presented October 7, 2025. Maryland's Office of Legislative Audits independently matched incarceration records from July 2017 through March 2025⧉ against HealthChoice enrollment in a fiscal-compliance audit published January 2026.

The combined current findings total $876.6 million.pdf) -- 95% of it Kentucky's concurrent-enrollment payments, which the APA notes equaled 2.06% of the state's $40.6 billion in total capitation.pdf) over the period.▸ For scale within the pattern's own terms: Kentucky's leak alone exceeds West Virginia's entire documented four-year overpayment roughly 26 times over. And Kentucky's was growing -- concurrent-enrollment capitation rose from $125.4 million in 2019 to $318.6 million in 2022.pdf), a 2.5× increase across the four calendar years examined.

Behind the premiums are 215,919 enrollee cases across the four current findings: 103,907 unique Kentuckians.pdf) covered by two states at once, 94,214 West Virginia incarcerated-individual cases and 15,346 deceased-individual cases⧉ (the WV report cautions cases are not deduplicated individuals across MCOs and years), and 2,452 incarcerated Marylanders⧉.▸ In Kentucky's 19-beneficiary deceased subgroup, $237,123 in capitation was paid after death -- for all 19.pdf). West Virginia's three MCOs split their incarcerated-case overpayments almost evenly: Aetna $10.87 million, The Health Plan $9.81 million, Unicare $10.99 million⧉ -- the uniformity itself suggesting a system-level gap rather than one bad contractor.

Federal regulation already answers each finding.▸ 42 CFR 435.1009⧉ bars federal financial participation for inmates of public institutions outright. 42 CFR 438.608⧉ requires every MCO contract to report identified overpayments to the state within 30 calendar days and to promptly notify the state of eligibility-affecting changes -- naming 'the death of an enrollee' explicitly. The ledgers read differently: West Virginia's corrections effort began only when the audit did, in September 2022, and its October 2025 report still counts $32.4 million potentially uncorrected⧉ against about $2.37 million recovered⧉. Maryland's disagreement is with its own record: the December 14, 2023 report flagged approximately $14 million and the agency's corrective machinery followed; the January 2026 report marks the identical finding Repeated⧉ with $7.8 million more. Kentucky's is structural: a state cannot stop paying for enrollees it cannot see are enrolled elsewhere, and until HHS-OIG supplied T-MSIS data, Kentucky's own processes had not identified the 48-state overlap⧉ at anything near its actual scale.

Each document sets its own clock.▸ West Virginia's Legislative Auditor directed BMS to continue correcting the historical overpayments and to report in writing to the Post Audits Subcommittee on completion⧉. Maryland's OLA repeat-finding process keeps the incarcerated-enrollee match on the audit cycle -- the next MCPA report will show whether Repeated becomes Not Repeated. Kentucky's examination stands as the first T-MSIS-scale test of concurrent enrollment; the APA's framing invites the obvious replication, since the same federal dataset exists for every state⧉. Three ledgers in four months is a sample, not a census: the pattern's documented floor is $876.6 million, and no document yet says where its ceiling is.
