Ballad Health’s Medicare Advantage Dispute With UnitedHealth Sent to Arbitration

A federal judge has dismissed Ballad Health’s lawsuit against UnitedHealth Group over alleged Medicare Advantage claim denials and underpayments, ruling that the dispute must proceed through arbitration rather than in federal court. The rural health system had accused UnitedHealthcare of improperly denying medically necessary care and underpaying hospitals serving patients across the Appalachian region.

The ruling does not resolve the underlying allegations. Instead, it determines that the contractual disputes between the organizations must be handled through arbitration.

• Ballad Health sued UnitedHealth in October 2025, seeking more than $65 million in damages.
• The health system alleged that UnitedHealthcare improperly denied or delayed Medicare Advantage claims and post-acute care.
• Ballad also accused UnitedHealth of using Medicare Advantage practices that overstated patients’ illnesses while limiting payment for care.
• UnitedHealth argued that contracts signed by Ballad’s predecessor organizations require disputes to be resolved through arbitration.
• A federal judge ruled September 14 that the case must proceed through arbitration.
• Ballad has previously said it will not renew its UnitedHealthcare Medicare Advantage contract after it expires on June 30, 2027.

Ballad Accused UnitedHealthcare of Systematic Claim Denials

Ballad Health filed the lawsuit in the U.S. District Court for the Eastern District of Tennessee in October 2025. The health system operates 19 hospitals across Northeast Tennessee and Southwest Virginia, serving a largely rural population in the Appalachian region.

In its complaint, Ballad alleged that UnitedHealthcare had systematically denied, delayed or underpaid claims for care that the health system’s physicians determined was medically necessary.

The health system claimed the disputed practices had caused it more than $65 million in damages over five years, with additional losses continuing to accumulate.

Ballad also alleged that UnitedHealthcare denied or limited coverage for post-acute services for Medicare Advantage members, potentially leaving patients in hospitals for longer periods while arrangements for rehabilitation or other post-acute care were delayed.

Lawsuit Raised Broader Medicare Advantage Concerns

Ballad’s complaint went beyond individual payment disputes.

The health system alleged that UnitedHealth had simultaneously benefited from Medicare Advantage payments based on higher reported levels of patient illness while denying certain medically necessary services.

Medicare Advantage insurers receive payments from the federal government that are adjusted according to beneficiaries’ health status. Ballad alleged that UnitedHealth subsidiaries had used aggressive coding practices to increase those payments while applying restrictive approaches to claims and post-acute care.

Those allegations remain unproven and were contested by UnitedHealth.

Ballad argued that the combination of higher risk-adjusted payments and claims denials created financial pressure for rural hospitals and could affect patients’ access to care.

Post-Acute Care Was a Major Point of Dispute

A significant part of Ballad’s complaint concerned patients who required rehabilitation or other post-acute services after hospitalization.

The health system alleged that UnitedHealthcare had denied coverage for post-acute care recommended by clinicians, resulting in some patients remaining in hospital beds longer than medically necessary while providers worked through coverage disputes.

Ballad said prolonged stays could increase pressure on hospital capacity and potentially expose patients to additional risks associated with longer hospitalizations.

The complaint also alleged that UnitedHealthcare had previously agreed to reimburse Ballad for patients who remained hospitalized longer than anticipated but had failed to make payments the health system believed were owed.

UnitedHealth Challenged the Lawsuit’s Venue

UnitedHealth responded by seeking to compel arbitration.

The insurer pointed to agreements signed by Mountain States Health Alliance and Wellmont Health System, the two organizations that merged in 2018 to create Ballad Health. According to UnitedHealth, those agreements contained provisions requiring disputes to be submitted to arbitration.

UnitedHealth argued that the contractual arbitration provisions covered the disputes raised by Ballad and that the federal lawsuit should therefore not proceed in court.

Ballad challenged that position, arguing that the arbitration provisions should not prevent the health system from pursuing its allegations in federal court. The health system also sought to invalidate the arbitration provisions on public-policy grounds.

Judge Orders Dispute Into Arbitration

U.S. District Judge Clifton Corker ruled September 14 that the contractual arbitration requirements must be enforced.

The judge acknowledged the seriousness of Ballad’s allegations but concluded that the health system had agreed to resolve relevant disputes through arbitration and had not identified a legal basis under Tennessee law that would allow the court to disregard that agreement.

As a result, the federal lawsuit has been dismissed in favor of arbitration.

The decision does not establish whether UnitedHealthcare improperly denied claims, underpaid Ballad or violated Medicare Advantage rules. Those substantive allegations would have to be addressed through the arbitration process.

Ballad Plans to End UnitedHealthcare Medicare Advantage Contract

Even before the latest court ruling, Ballad had announced that it would not renew its Medicare Advantage agreement with UnitedHealthcare when the contract expires on June 30, 2027.

The decision applies specifically to the Medicare Advantage relationship. Ballad said it intends to continue working with UnitedHealth on its commercial, Medicaid and Affordable Care Act exchange plans when those agreements come up for renewal.

Ballad CEO Alan Levine previously said the health system’s decision reflected financial and operational challenges associated with providing care under the Medicare Advantage arrangement.

Broader Scrutiny of Medicare Advantage Denials

The dispute comes amid broader federal scrutiny of coverage denials in Medicare Advantage.

A June 2026 report from the Department of Health and Human Services’ Office of Inspector General found that Medicare Advantage insurers sometimes denied requests for post-acute care that met Medicare coverage rules. The report also found that insurers frequently reversed those decisions when beneficiaries or providers appealed.

The OIG findings included scrutiny of post-acute care decisions involving NaviHealth, a UnitedHealth subsidiary that evaluates certain care requests for insurers.

The federal findings are separate from Ballad Health’s lawsuit and do not establish that UnitedHealthcare violated the law in its dealings with Ballad.

What Happens Next

The federal court proceeding is now closed following the arbitration ruling, but the underlying dispute has not necessarily ended.

Ballad’s claims will have to be pursued through the contractual arbitration process rather than through the federal lawsuit. The arbitration could determine whether the parties’ agreements were breached and whether Ballad is entitled to financial compensation.

Meanwhile, Ballad’s decision not to renew its Medicare Advantage agreement means the dispute could have longer-term implications for how UnitedHealthcare serves Medicare Advantage members in the Appalachian communities covered by the health system.

For now, the court’s ruling addresses how the dispute will be resolved, not who is ultimately responsible for the alleged claims denials and underpayments.

Ballad Health’s Medicare Advantage dispute with UnitedHealth is moving from federal court to arbitration after a judge dismissed the health system’s lawsuit. The ruling came on September 14, 2026, after UnitedHealth argued that contractual agreements required disputes between the organizations to be resolved through arbitration.

Ballad Health’s Medicare Advantage Dispute

Ballad Health’s lawsuit, filed in October 2025, alleged that UnitedHealth had improperly denied, delayed, or underpaid certain Medicare Advantage claims. The health system sought more than $65 million in damages.

Ballad Health also alleged that UnitedHealth misrepresented the severity of patients’ illnesses to federal regulators to obtain higher Medicare Advantage payments. These are allegations made by Ballad Health and have not been established as findings against UnitedHealth.

The dispute centers partly on agreements signed by organizations that later became part of Ballad Health. UnitedHealth argued that those agreements contained arbitration provisions covering disputes between the parties.

U.S. District Judge Clifton Corker concluded that the arbitration agreements were valid and that the case should proceed according to those contractual provisions rather than continue in federal court.

Ballad Health’s Claims Against UnitedHealth

Ballad Health’s original complaint alleged that UnitedHealth had engaged in a pattern of claim denials, payment delays, and failures to meet payment obligations. The complaint stated that the alleged conduct had caused the health system significant financial damages.

Ballad Health also challenged the arbitration provisions, arguing that the Medicare Advantage-related dispute involved broader public-policy and transparency concerns. UnitedHealth disputed those arguments and sought to enforce the arbitration agreements.

Ballad Health’s Medicare Advantage Contract

The dispute also has implications for the organizations’ future relationship. Ballad Health previously stated that it would not renew its Medicare Advantage contract with UnitedHealthcare when the agreement expires on June 30, 2027. The health system said it planned to continue working with UnitedHealth on commercial, Medicaid, and ACA plans.

Broader Healthcare Implications

Ballad Health’s case illustrates the contractual and financial disputes that can arise between healthcare providers and Medicare Advantage insurers over claims, reimbursement, and payment policies.

Ballad Health’s Arbitration Process

Ballad Health’s move toward arbitration shifts the dispute into a private dispute-resolution process. Arbitration generally involves an independent arbitrator or panel reviewing contractual claims and arguments presented by the parties.

For Ballad Health’s case, the process is expected to focus on contractual obligations surrounding Medicare Advantage claims and reimbursement. Both sides will have an opportunity to present their positions and supporting evidence.

Ballad Health’s Financial Concerns

Ballad Health’s lawsuit sought more than $65 million in damages connected to allegations concerning Medicare Advantage payments. Disputes over reimbursement can have significant financial implications for healthcare systems because payment levels affect operating resources.

The allegations against UnitedHealth remain contested. The arbitration process will provide an opportunity for both parties to present evidence concerning the disputed claims and contractual obligations.

Ballad Health’s Relationship With UnitedHealth

Ballad Health’s dispute with UnitedHealth occurs within a broader contractual relationship involving multiple types of health coverage. The Medicare Advantage agreement is at the center of the dispute, while other insurance relationships may continue.
