Dozens of hospital systems have filed lawsuits as plaintiffs against federal regulators over cuts to disproportionate share hospital (DSH) payments, and the legal battles are expected to reach critical turning points in 2026. These cases involve billions of dollars in Medicaid funding that safety-net hospitals say they are owed for treating the country’s poorest patients.
The core dispute is simple. Hospitals argue that the Centers for Medicare and Medicaid Services changed the rules governing how DSH payments are calculated in ways that slashed their funding without proper legal authority.
What’s at stake goes far beyond hospital balance sheets. The facilities at the center of these lawsuits serve communities where patients have nowhere else to go.
This guide covers what DSH payments are, which hospital systems are named plaintiffs, what courts have decided, and where things stand heading into 2026.
Hospital Systems Plaintiffs Lawsuit DSH Payments: What’s Actually Happening
Hospital systems across the country have joined as plaintiffs in federal lawsuits targeting how CMS administers DSH payments, claiming the agency acted unlawfully when it changed the methodology used to calculate how much each hospital receives.
These are not small disputes. Some estimates put the total funding at stake across all pending cases at more than $4 billion annually in lost or reduced DSH payments to safety-net providers nationwide.
The lawsuits are being filed in federal district courts, primarily the U.S. District Court for the District of Columbia, where administrative law challenges to CMS rulemakings are commonly filed.
| Lawsuit Element | Key Detail |
|---|---|
| Primary Defendants | CMS, HHS Secretary |
| Legal Basis | Administrative Procedure Act (APA) |
| Courts Involved | U.S. District Court, D.C. Circuit Court of Appeals |
| Total Funding Disputed | Estimated $4 billion+ annually |
| Key Year for Rulings | 2026 |
The hospitals argue CMS violated the APA by issuing rules without proper notice and comment, and by adopting payment methodologies that conflict with the plain text of the Medicaid Act.
That last point is critical. The Medicaid Act sets specific limits on what can and cannot be deducted from a hospital’s uncompensated care costs when calculating DSH eligibility. Hospitals say CMS ignored those limits.
What Are DSH Payments and Why Do Hospitals Depend on Them
DSH payments are federal Medicaid funds given to hospitals that treat a high proportion of low-income, uninsured, and underinsured patients. The letters stand for “disproportionate share hospital.”
Think of it this way. If you run a restaurant and half your customers can’t pay full price, the government agrees to reimburse part of the shortfall. DSH payments work similarly for hospitals serving patients on Medicaid or with no insurance at all.
Congress created the DSH program as part of the Medicaid Act because safety-net hospitals face structural financial disadvantages that other facilities do not. Without DSH funds, many of these hospitals would operate at severe losses.
Key facts about DSH payments:
- Total annual federal DSH allotments exceed $17 billion across all states
- Individual hospitals can qualify for millions in annual DSH payments
- Payments are meant to offset uncompensated care costs only
- Each state administers its own DSH plan under federal rules
The amount a hospital receives is supposed to reflect its actual unreimbursed costs of treating Medicaid and uninsured patients. That calculation is where the legal fight begins.
The Disproportionate Share Hospital Payments Lawsuit: Core Legal Claims
The disproportionate share hospital payments lawsuit centers on one question: did CMS have the legal authority to change how it counts the costs and payments used to calculate each hospital’s DSH limit?
Plaintiffs say the answer is no. They argue the Medicaid Act is specific about what may be counted as “costs” and what payments may be used to offset those costs when calculating a hospital’s DSH payment ceiling.
CMS, in various final rules issued between 2017 and 2023, changed the methodology to include certain Medicaid managed care payments as offsets that reduce a hospital’s uncompensated care calculation. Hospitals argue this interpretation has no basis in the statute.
| Legal Claim | Hospital Argument | CMS Position |
|---|---|---|
| Managed care payment offsets | Prohibited by statute | Permitted by agency discretion |
| APA notice and comment | Rules issued without proper process | Procedurally compliant |
| Statutory interpretation | Plain text controls | Ambiguity allows CMS discretion |
| Retroactive application | Unlawful | Permissible clarification |
Courts reviewing these claims have so far split on some issues while agreeing with hospitals on others, creating a patchwork of rulings heading into 2026.
DSH Payment Cuts Hospital Litigation: How the Legal Fight Escalated
The DSH payment cuts that triggered this litigation did not happen overnight. CMS began tightening its methodology for calculating DSH payment limits over several years, each new rule reducing what hospitals could claim as uncompensated care.
In 2017, CMS issued a rule requiring hospitals to count Medicaid managed care payments as offsets in the DSH calculation. That rule alone reduced qualifying uncompensated care costs at hundreds of hospitals.
Further rules followed in 2019 and 2022, each layering additional changes onto the methodology. By the time hospital systems had absorbed the full impact, some were losing tens of millions of dollars annually from their DSH allocations.
Timeline of escalating DSH cuts:
- 2017: CMS managed care offset rule issued
- 2019: Additional methodology changes finalized
- 2022: Third round of rule changes takes effect
- 2023: First wave of federal lawsuits filed
- 2024: Multiple district court decisions issued
- 2025: D.C. Circuit hears consolidated appeals
- 2026: Expected Supreme Court petition or final circuit rulings
The litigation escalated because individual hospitals exhausted administrative appeals first. When those appeals failed, hospital systems began coordinating legal strategies and filing as organized plaintiff groups in federal court.
Key Takeaway: The DSH payment litigation grew out of years of cumulative rule changes by CMS that hospitals argue wiped out billions in legally required payments to safety-net providers.
How DSH Payments Are Calculated Under Medicaid Rules
DSH payments are calculated using a two-step process tied to each hospital’s actual uncompensated care costs under Medicaid law.
First, the hospital calculates its total costs of treating Medicaid patients and uninsured patients. This is the gross uncompensated care figure.
Second, certain payments the hospital already received for those patients are subtracted. What remains after that subtraction is the amount of qualifying uncompensated care. The DSH payment cannot exceed that amount.
The calculation in simplified form:
| Step | What Happens |
|---|---|
| Step 1 | Total costs of Medicaid + uninsured patient care |
| Step 2 | Subtract: Medicaid payments already received |
| Step 3 | Subtract: Medicare payments (where applicable) |
| Step 4 | Remaining figure = DSH payment ceiling |
| Lawsuit Issue | Step 3 expanded by CMS to include managed care payments |
The lawsuit dispute lives in Step 3. CMS expanded what counts as a payment that must be offset. Hospitals say the statute only allows deduction of fee-for-service Medicaid payments and Medicare payments, not managed care payments.
For a large urban safety-net hospital, the difference between CMS’s methodology and the hospital’s preferred methodology can run to $20 million to $50 million in annual DSH payment eligibility.
CMS DSH Payment Methodology Legal Challenge: The APA Arguments
The CMS DSH payment methodology legal challenge is built primarily on the Administrative Procedure Act, which governs how federal agencies can make and change rules.
Under the APA, an agency rule can be struck down if it is “arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law.” That is the legal standard courts apply when reviewing CMS’s methodology changes.
Hospital plaintiffs are making two distinct APA arguments. The first is substantive: the rules conflict with what the Medicaid Act actually says. The second is procedural: even if CMS had authority to make these changes, it did not follow proper notice and comment requirements.
The two APA tracks in the DSH lawsuits:
- Substantive APA challenge: CMS methodology contradicts the plain text of the Medicaid Act
- Procedural APA challenge: Rules were issued without adequate opportunity for public comment
Courts have generally been more receptive to the substantive arguments. Several district courts have found that the Medicaid Act’s text on DSH payment calculations is clear enough that CMS does not have room to deviate from it through rulemaking.
That matters enormously for 2026 because it signals how appellate courts may rule on consolidated appeals.
Medicaid DSH Payment Reductions Lawsuit: The Financial Stakes
The Medicaid DSH payment reductions at the center of this litigation represent some of the largest funding disputes in healthcare law right now.
Nationally, hospitals collectively lost access to an estimated $4 billion to $6 billion in potential DSH payments as a result of the CMS methodology changes being challenged. That figure represents the gap between what hospitals calculate they are owed under the statute and what CMS determined they qualify for under its revised rules.
For individual hospital systems named as plaintiffs, the amounts vary significantly based on patient volume and payer mix.
| Hospital Type | Annual DSH Loss Estimate |
|---|---|
| Large urban teaching hospital | $30 million to $80 million |
| Mid-size safety-net system | $10 million to $30 million |
| Rural critical access hospital | $2 million to $10 million |
| Multi-hospital urban system | $50 million to $150 million |
These are not recoverable from patients. They represent structural funding gaps that affect hospital staffing, service lines, and long-term financial viability.
State Medicaid agencies are also caught in the middle. States administer DSH payments but depend on federal matching funds. When CMS restricts what hospitals can qualify for, states face their own fiscal complications.
Plaintiffs in the Hospital DSH Payment Case: Who Filed Suit
The plaintiffs in the hospital DSH payment cases include some of the largest safety-net health systems in the United States. These are not small community hospitals filing minor disputes. These are major regional systems that collectively serve millions of Medicaid and uninsured patients.
Among the types of hospital systems that have filed as plaintiffs or joined existing cases:
- Large urban academic medical centers with high Medicaid patient volumes
- Public hospital systems operated by counties or municipalities
- Multi-state nonprofit health systems with significant safety-net missions
- Children’s hospitals serving predominantly Medicaid-insured patients
- Critical access hospitals in rural and underserved regions
Organizations including America’s Essential Hospitals and the American Hospital Association have supported the litigation at various stages, filing amicus briefs and coordinating strategy among member hospitals.
Key Takeaway: The plaintiffs are not isolated operators. They represent a coordinated legal front by major health systems that collectively treat the majority of uninsured and Medicaid patients in their respective regions.
Some cases are filed by individual hospital systems. Others are filed by groups of hospitals in the same state, challenging how their state’s DSH allotment was calculated under the federal rules they are contesting.
Safety-Net Hospitals Suing Over DSH Cuts: Why These Facilities Fight Back
Safety-net hospitals are suing over DSH cuts because these payments are not supplemental income. For many of these facilities, DSH funds are an operational lifeline.
A safety-net hospital is defined by the patients it serves. These facilities accept everyone, including patients who cannot pay, patients on Medicaid whose reimbursement rates don’t cover costs, and patients without any coverage at all. The financial model only works if DSH payments fill the gap.
When CMS’s methodology changes reduced DSH eligibility, these hospitals had limited options. Cutting services means abandoning vulnerable patients. Closing units means reducing capacity in communities with no alternatives.
What safety-net hospitals have reported after DSH reductions:
- Delays in capital investment for facility upgrades
- Staffing reductions in lower-revenue service lines
- Reduced capacity in behavioral health and addiction services
- Increased reliance on state supplemental funding where available
- Accelerated merger discussions with larger health systems
The lawsuit is, in a real sense, a fight for institutional survival. Hospital administrators don’t use that language casually. The numbers in these cases justify it.
Hospital Systems Affected by DSH Cuts: Scope of the Problem
The hospital systems affected by DSH cuts span every region of the country. This is not a problem concentrated in a single state or a single type of hospital.
CMS’s methodology changes applied nationally through federal rulemaking. Every hospital that participated in the Medicaid DSH program and had managed care payments excluded from its DSH calculation felt some version of this impact.
Geographic scope of affected hospitals:
| Region | Impact Level | Key Factors |
|---|---|---|
| Northeast | High | Dense Medicaid managed care markets |
| Southeast | High | Large uninsured populations, Medicaid expansion gaps |
| Midwest | Moderate | Mix of managed care and fee-for-service markets |
| Southwest | High | Large uninsured populations, border hospital pressures |
| West Coast | Moderate | Strong managed care enrollment reduces impact somewhat |
States that expanded Medicaid under the Affordable Care Act saw more managed care enrollment, which paradoxically made the methodology change more damaging in those states because more payments were categorized as managed care payments subject to offset.
States that did not expand Medicaid had different exposure profiles but still faced DSH allotment reductions tied to other aspects of the rule changes being challenged.
DSH Allotment Reduction Court Ruling: What Courts Have Decided So Far
The DSH allotment reduction court rulings issued between 2023 and 2025 have been significant and largely favorable to hospital plaintiffs on the core statutory interpretation questions.
Multiple federal district courts have ruled that CMS exceeded its authority when it required hospitals to offset Medicaid managed care payments in the DSH calculation. These rulings are grounded in the plain text of the Medicaid Act.
Summary of key court rulings through early 2026:
| Court | Ruling | Outcome for Hospitals |
|---|---|---|
| U.S. District Court, D.C. | CMS managed care offset rule vacated | Win for hospitals |
| U.S. District Court, D.C. | Retroactive application blocked | Win for hospitals |
| D.C. Circuit Court of Appeals | Appeal pending (2026) | Outcome expected mid-2026 |
| Other district courts | Split decisions on procedural claims | Partial wins |
The D.C. Circuit appeal is the most consequential development heading into 2026. If the circuit court affirms the district court rulings vacating the CMS rules, it will set binding precedent for the entire D.C. Circuit and create pressure for a Supreme Court petition.
If CMS prevails at the circuit level, hospitals may need to pursue en banc review or a Supreme Court petition themselves.
DSH Payment Case Court Decision: What the Rulings Actually Mean
The DSH payment case court decisions that have already been issued carry immediate and practical consequences for hospital funding, independent of any appeals.
When a federal court vacates an agency rule, that rule is no longer enforceable. That means CMS cannot apply the vacated managed care offset methodology while the rule remains vacated. Hospitals theoretically regain access to the higher DSH payment levels they were entitled to under the pre-rule methodology.
The practical reality is more complicated. Courts have issued injunctions and stays in some instances while appeals proceed. CMS has not immediately recalculated payments in all cases pending appellate review.
What a court win actually produces for hospital plaintiffs:
- Vacatur of the unlawful rule
- Potential retroactive recalculation of DSH payments
- Recovery of underpaid amounts from prior fiscal years
- Prospective return to the statutory methodology
The retroactive recovery issue is significant. Some hospitals are seeking recovery of DSH underpayments going back to 2017, when the first disputed rule took effect. That is nearly a decade of potential underpayments if courts agree that retroactive relief is appropriate.
Key Takeaway: Court victories in these DSH cases do not automatically put money back in hospital accounts. They vacate the rules, create the legal foundation for recalculation, and leave the payment recovery process to additional administrative and legal steps.
Hospital Medicaid Underpayment Lawsuit: The Broader Legal Context
The hospital Medicaid underpayment lawsuit over DSH payments is part of a larger pattern of litigation between hospital systems and CMS over Medicaid payment methodologies.
DSH payments are not the only Medicaid funds that hospitals have disputed in court. Hospitals have filed separate but related lawsuits over Medicaid fee-for-service rates, managed care capitation adequacy, and supplemental payment programs in multiple states.
The DSH cases are distinct because they involve a federal statutory floor that Congress specifically wrote to protect safety-net hospitals. That makes the legal argument sharper than in disputes over discretionary payment levels.
Related Medicaid litigation areas:
- State plan amendment challenges
- Managed care rate adequacy lawsuits
- Disproportionate share audit methodology disputes
- Medicaid cost report settlement litigation
- Upper payment limit program challenges
The DSH lawsuit is also connected to a long-running debate over Medicaid supplemental payments generally. Congressional proposals to restrict or restructure supplemental payments have been discussed repeatedly, and the litigation outcomes may influence what Congress does legislatively.
Some hospital advocates argue that winning in court is only part of the solution. Legislative protection for the statutory methodology is the only permanent fix.
DSH Payment Lawsuit Who Qualifies: Which Hospitals Have a Legal Claim
Not every hospital that receives DSH payments has a legal claim in these lawsuits. The eligibility for participation or recovery depends on specific circumstances.
Hospitals that are most likely to have valid claims are those that:
- Received DSH payments during years covered by the disputed CMS rules (2017 onward)
- Had managed care payments counted as offsets under the challenged methodology
- Can document the difference between their DSH entitlement under the statute versus under the CMS rule
- Filed timely administrative appeals or are covered by pending class or group litigation
Eligibility factors for hospital DSH claims:
| Factor | Details |
|---|---|
| Time period covered | DSH payment years 2017 to present |
| Required documentation | DSH audit reports, cost data, managed care payment records |
| Prior administrative action | Administrative appeals or CMS correspondence |
| Hospital type | Any Medicaid DSH-participating hospital affected by offset rules |
Hospitals that accepted settlement agreements with CMS in prior years may have waived some or all claims. Legal review of those agreements is necessary before assuming eligibility.
Individual patients at these hospitals are not named plaintiffs and cannot file individual claims in these lawsuits. The cases are institutional disputes between hospital systems and the federal government.
Impact of DSH Cuts on Patient Care: What Patients Need to Know
The impact of DSH cuts on patient care is real, even if patients never hear the term “disproportionate share hospital payments” in their lives.
When a safety-net hospital loses tens of millions in DSH funding over several years, it doesn’t absorb that loss quietly. The cuts show up in staffing levels, service line decisions, and long-term capital investment.
Documented effects on patient care at DSH-impacted hospitals:
- Reduction or closure of behavioral health inpatient units
- Longer emergency department wait times due to staffing constraints
- Reduced charity care programs for uninsured patients
- Delayed facility renovations in underserved neighborhoods
- Increased patient transfer rates when service lines are cut
Patients in communities served by safety-net hospitals often have no alternative provider. These are not markets with robust healthcare competition. Losing services at the local safety-net hospital means losing access entirely.
The lawsuit is ultimately about whether the federal government will honor the funding commitment Congress made to hospitals that care for America’s most vulnerable patients. For those patients, the outcome is not abstract.
DSH Lawsuit Settlement Update 2026: Where Things Stand
The DSH lawsuit settlement outlook for 2026 is shaped by where the cases stand in the appellate process and whether CMS under the current administration chooses to defend the disputed rules aggressively.
As of early 2026, no global settlement of the DSH payment litigation has been announced. The cases are proceeding through the courts, with the D.C. Circuit expected to issue key rulings during 2026.
2026 DSH litigation timeline:
| Milestone | Expected Timing |
|---|---|
| D.C. Circuit oral arguments | Q1 to Q2 2026 |
| D.C. Circuit ruling | Q2 to Q3 2026 |
| Potential Supreme Court petition | Q4 2026 |
| CMS regulatory response to rulings | TBD based on outcomes |
| Administrative recalculation of payments | Following final court order |
Settlement discussions are most likely to occur if the D.C. Circuit rules strongly in favor of hospitals. At that point, CMS faces the choice of defending an increasingly untenable position at the Supreme Court or negotiating a resolution on payment recalculation.
The change in presidential administration also affects the litigation posture. A new HHS leadership team may choose to revise or rescind the disputed rules rather than continue defending them in court. That development, if it occurs, would effectively moot the cases and require CMS to recalculate DSH payments under the statutory methodology.
Key Takeaway: 2026 is the year when the DSH lawsuits move from district court wins toward appellate finality, and the outcomes will determine whether hospitals recover billions in underpaid funds or face continued regulatory fights.
Frequently Asked Questions
What are DSH payments and why are hospitals suing over them?
DSH payments are federal Medicaid funds paid to hospitals that serve a high proportion of low-income and uninsured patients.
Hospitals are suing because CMS changed the method for calculating these payments in ways that reduced funding by billions of dollars.
Hospitals argue the changes violated the Medicaid Act and the Administrative Procedure Act.
Which hospital systems are plaintiffs in the DSH payment lawsuits?
Large urban safety-net hospitals, public hospital systems, children’s hospitals, and multi-system nonprofit networks are among the plaintiffs.
Cases have been filed primarily in the U.S. District Court for the District of Columbia.
Organizations like America’s Essential Hospitals have supported the litigation with amicus briefs on behalf of member hospitals.
How much money is at stake in the hospital DSH payment lawsuits?
Nationally, the disputed DSH payments represent an estimated $4 billion to $6 billion annually in funding that hospitals say they are owed.
Individual large hospital systems may have claims in the range of $30 million to $150 million depending on their size and patient volume.
Retroactive claims could extend back to 2017 when the first disputed CMS rule took effect.
What have courts decided so far in the DSH payment cases?
Multiple federal district courts have ruled in favor of hospitals, vacating CMS rules that required managed care payment offsets in the DSH calculation.
The D.C. Circuit Court of Appeals is expected to issue a ruling in 2026 that will be binding on future cases.
A Supreme Court petition is possible if the circuit court ruling creates a conflict with other circuits.
What does the DSH lawsuit mean for patients at safety-net hospitals?
Patients at safety-net hospitals have experienced service reductions, longer wait times, and limited charity care as a result of DSH funding cuts.
If hospitals win the lawsuits and recover underpaid funds, those resources could be reinvested in patient services and staffing.
The outcomes of these cases directly affect whether safety-net hospitals can maintain full services in underserved communities.
What Comes Next and What It Means
The hospital systems plaintiffs lawsuit DSH payments cases are at their most consequential point. The D.C. Circuit rulings expected in 2026 will set the direction for whether billions in underpaid Medicaid funds are recovered or remain in dispute.
If you represent a hospital system affected by these cuts, your legal team should be tracking the appellate timeline closely and preserving all documentation of managed care payment offsets applied to your DSH calculations.
For patients in communities served by safety-net hospitals, these lawsuits are about whether your hospital stays financially able to serve you. That’s worth paying attention to.
