Medicaid's Blank Check Just Got Canceled: CMS's Crackdown on SDP

May 21, 2026  |  Medicaid, CMS, State-Directed Payments (SDP)

Mike Rawaan, Founder and Managing Director

CMS just pulled the emergency brake on the Medicaid Gravy train. On May 20, CMS proposed what it is calling a "sweeping crackdown" on state-directed payments (SDPs) in Medicaid, which is the financing mechanism states have quietly weaponized for years to pull down federal dollars far beyond their actual share. The proposed rule, formally titled the Medicaid Managed Care State Directed Payments and Medicaid Fee-for-Service Targeted Practitioner Payments Proposed Rule (CMS-2449-P), would cap payments to Medicare-equivalent rates and is projected to save $775 billion over 10 years, including $510 billion in federal savings.

What Is a State-Directed Payment — and Why Does It Matter?

In Medicaid managed care (Managed Care Organizations or MCOs), states direct health plans on how to pay providers. In theory, SDPs allow states to boost provider rates, improve access, and reward quality. In practice, many states have used them as a federal matching funds arbitrage play. However, that's not how the money is often used.

Here is the scheme: states impose provider taxes or arrange intergovernmental transfers to generate the "non-federal share" of Medicaid funding. That money goes back into the system - often through the same providers who paid it - while simultaneously unlocking a much larger federal match. A 2024 MACPAC report confirmed that more than half of directed payments are financed through these mechanisms. The state contributes relatively little. The federal government picks up the tab. Providers, particularly large hospital systems, see inflated payments with no corresponding improvement in care delivery.

The greatest evidence is in the growth trajectory: just two states used SDPs in 2016. By fiscal year 2025, 41 states had adopted them, and these payments account for more than a quarter of all Medicaid managed care spending. Without intervention, annual SDP spending would balloon from $107 billion in FY2024 to $296 billion by FY2034, which is simply unsustainable, and that's why CMS has intervened.

What the Rule Actually Does

CMS is moving to reform both managed care and fee-for-service simultaneously:

Tying Medicaid to Medicare rates. For rating periods beginning on or after July 4, 2025, SDPs for hospital, nursing facility, and academic medical center practitioner services would be capped at 100% of Medicare rates in Medicaid expansion states and 110% in non-expansion states. By January 1, 2029, the rate cap extends to all SDP categories across all states, Washington, D.C., and territories. If no comparable Medicare rate exists, the cap defaults to the state plan-approved rate. This is the defining structural shift which anchors Medicaid rates to a federal benchmark vs. whatever a state can engineer.

Phasing out "uniform increase" arrangements. These broad, blunt-instrument payment increases have been among the most abused SDP structures. CMS proposes eliminating this category over time.

Grandfathering with a sunset. Certain existing SDPs that meet specific criteria may qualify for a temporary grandfather period, but the relief is not permanent. Starting January 1, 2028, grandfathered payments would phase down by 10 percentage points annually until they reach the new rate limits. States cannot lock in today's inflated payment structures indefinitely.

FFS supplemental payment limits. On the fee-for-service side, targeted Medicaid practitioner payments face the same 100%/110% Medicare rate cap. States currently operating above those limits must submit a state plan amendment to comply by the first state fiscal year beginning on or after January 1, 2029.

The Policy Context: This Doesn't Stand Alone

Industry analysts would be wrong to read this rule in isolation. It is the second major Medicaid financing reform move in as many months.

On April 2, CMS finalized a separate rule closing the provider tax loophole, which bans states from imposing higher tax rates on Medicaid business than non-Medicaid business, and blocking indirect tax structures designed to route around those limits. Provider taxes generate over $24 billion annually for state budgets, with one state alone pulling in more than $13 billion through these arrangements.

Together, these two rules form a coordinated offensive on the financing mechanisms states use to draw down disproportionate federal Medicaid dollars. Add in the One Big Beautiful Bill Act (OBBBA), which legislatively mandated the SDP payment limits CMS is now formalizing, and the policy environment could not be clearer. Congress acted. CMS is executing. States need to adapt.

Who Gets Hit and Who Should be Watching

The provider community has reason to pay close attention. The American Hospital Association has already weighed in, affirming the importance of Medicaid's fiscal integrity while raising pointed questions about implementation, transition timelines, and the risk to access for vulnerable populations. Large health systems, particularly those in states with generous SDP programs, face direct revenue pressure. HCA Healthcare, for example, has already projected a $250 to $400 million decline in net benefit from SDPs in 2026 alone.

States face a harder planning environment. Those that have built Medicaid supplemental payment structures on top of provider tax financing now have a shrinking runway to restructure their programs — or accept a significant reduction in provider payment capacity.

Managed care organizations face margin compression in the near term as payment floors fall. Plans that have structured their actuarial models around inflated SDP-driven rates will need to recalibrate.

The 60-day comment period is open. But stakeholders should not mistake a comment period for a change in direction. The statutory mandate from OBBBA is in place, and the CMS guidance issued in September 2025 already telegraphed this rule's core provisions.

The Bottom Line

Medicaid was never designed to be a federal matching funds arbitrage instrument. For years, sophisticated states and large health systems found the seams in the program and exploited them at an enormous cost to federal taxpayers and to the program's long-term viability.

CMS is correcting the course. The rule puts a Medicare-based ceiling on what Medicaid pays, phases out the financing structures that allowed payment inflation without accountability, and forces states to confront the real cost of their Medicaid commitments.

This is the right policy call. However, the implementation details - grandfathering terms, phase-down timelines, access safeguards - deserve rigorous scrutiny during the comment period. But the directional is set.

Medicaid's blank check has been canceled. The real work now is figuring out what comes next.
