The billion-dollar question nobody can answer

What the documents actually say

Start with the two poles. Illinois runs the textbook version: two percent of capitation withheld, returned in equal halves — one percent against pay-for-performance results on measures organized into pillars (adult behavioral health, child behavioral health, maternal and child health, equity, community and health promotion), and one percent against the accuracy of the plan’s reporting itself [IL HFS, P4P/P4R Performance Methodology, HEDIS MY2025]. New York, by contrast, withholds nothing: its Quality Incentive awards a tiered bonus of up to three percent on top of premium, scored 80 percent on quality of care and 20 percent on member experience, with deductions for compliance deficiencies [NY DOH, Quality Incentive Report 2023]. Same policy goal; opposite behavioral frame. One threatens a loss, the other offers a prize — and whether that difference matters is precisely the kind of question the public record has never been assembled to answer.

Between the poles sits everything else. Texas places up to three percent of medical premium at risk and — nearly alone among states — publishes what happened next: its annual quality report lists actual recoupments collected, by program and plan [TX HHSC, P4Q; Annual Report on Quality Measures and VBP, Dec. 2024]. California layers a capitation withhold on top of a sanctions regime with real teeth: in December 2024, the state announced monetary sanctions against twenty of its twenty-four Medi-Cal managed care plans for missing minimum performance levels — and posted the individual sanction letters publicly [DHCS, MCAS Enforcement, Dec. 2024]. Maryland ran a value-based purchasing program for two decades, then sunset it after measurement year 2021 in favor of a redesigned Population Health Incentive Program [MD HealthChoice §1115 reports]. Pennsylvania has operated pay-for-performance since 2005 and does publish results — inside annual technical reports that run to hundreds of pages [PA DHS, HealthChoices ATR 2025–26].

So why can’t anyone answer the question?

Because the record is public the way a scattered archive is public. The design lives in contract appendices and rate methodologies; the results live in external quality review reports that federal advisors have themselves described as difficult for most audiences to find and comprehend; the dollars live in budget documents; and almost nothing is assembled across states or across years. Three questions that should be trivially answerable mostly are not: How much money was actually at stake last year? Which plans earned it back? Did the measures that carried dollars improve faster than the ones that didn’t?

In a minority of states — Texas and California foremost — you can begin to answer from published documents. In most, you cannot. That asymmetry is itself a finding, and it is about to collide with federal policy: rules finalized in 2024 will push every state toward a public quality rating system for its Medicaid plans. States that already show their receipts will look prescient. States that cannot say where the withhold went will be asked.

What we’re doing about it

This fall, The Chuma Institute publishes the Medicaid Quality Withhold Scorecard — the first systematic grading of these programs across twenty states, scored on six dimensions: dollars at stake, measure selection, benchmark rigor, equity linkage, transparency, and program stability. Every grade will cite the primary documents it rests on, and where a state’s documentation cannot be found publicly, that absence will be reported as the finding it is. Between now and then, this weekly series walks the evidence one state at a time. Next week: the full anatomy of the Illinois withhold — including the quiet redistribution rule that moves real dollars when a measure goes not-applicable.
