Preventing Hospital Overbilling of Medicare Act
Introduced April 24, 2025 · Last action April 24, 2025
Plain English Summary
This bill requires hospitals to bill Medicare and private insurers separately and transparently when they provide services at off-campus outpatient departments (clinics, urgent care centers, imaging centers owned by hospitals but located away from the main hospital campus). Currently, hospitals can bill these services as if they were provided on the main campus, triggering higher hospital-level payments. Starting January 1, 2026, each off-campus department must have its own billing identifier and must use lower outpatient rates, preventing what the bill calls 'hospital overbilling.'
Who benefits
Medicare and Medicaid beneficiaries who will pay lower out-of-pocket costs when off-campus departments are billed at lower rates; private insurance enrollees whose premiums may decrease if claims are paid at lower rates; employers offering group health plans who will see reduced claim costs; Medicare and private insurers (reduced claim reimbursement burden); the federal government (reduced Medicare spending); state insurance commissioners and regulators who gain enforcement authority; primary care physicians and independent urgent care operators who face less price competition from hospital-owned off-campus facilities.
Who pays / loses
Hospitals and hospital systems that currently bill off-campus services at higher rates; hospital administrators and billing departments (implementation costs for new billing systems, training, and operational changes); hospital investors and shareholders (reduced revenue from off-campus billing); private equity firms owning hospital networks that rely on off-campus billing strategies; health IT vendors required to update billing transaction standards; private insurers (short-term administrative costs to reject and reprocess claims); group health plans (administrative costs for claims management).
Funding & Lobbying Interests
The bill directly targets hospital revenue-maximization practices. Sponsors of site-neutral billing policies are typically supported by Medicare advocacy organizations, patient safety groups, and consumer advocates concerned about surprise billing and cost inflation. The sponsor (Rep. Victoria Spartz) received minimal healthcare industry contributions ($3,750 in 2024), suggesting the bill is not driven by healthcare donor influence. No PAC contributions were received, further indicating independence from organized industry lobbying. The bill aligns with prior federal efforts to enforce site-neutral payment policies (established in the Bipartisan Budget Act of 2015), indicating cross-party consensus that hospital billing manipulation is a legitimate policy problem. Private insurers and employer groups backing healthcare cost-containment measures would have a financial interest in passage, though direct evidence of lobbying is not available in the provided data.
Political Impact
Affected Groups
Medicare beneficiaries (approximately 67 million enrolled, 2024) and Medicaid enrollees who will face lower out-of-pocket costs; privately insured employees and families (approximately 157 million covered by employer group health plans, 2024); hospital-dependent rural and underserved communities where hospital-owned off-campus departments may be the primary source of accessible care; employees at hospital systems (estimated 5.7 million in U.S. hospital employment) affected by billing system implementation costs; uninsured and underinsured patients who may benefit from downstream cost reductions.
Political Subtext
Proponents argue this bill closes a loophole that allows hospitals to disguise off-campus services as hospital services to trigger higher reimbursement rates, driving up healthcare costs without improving quality. They contend the current system enables surprise billing and cost inflation. Critics (primarily hospital associations and health system lobbies) argue that off-campus clinics provide needed access and expansion of services, and that the separate billing requirement imposes compliance costs and administrative burden without evidence that it reduces overall spending or improves outcomes. Non-partisan evidence from CBO and GAO reports on site-neutral payment shows mixed results: some studies document reduction in overall spending per service when off-campus clinics are paid at outpatient rather than hospital rates, but other analyses show hospitals respond by increasing volume of low-acuity services, which may offset savings. The Bipartisan Budget Act of 2015 included partial site-neutral provisions that reduced some off-campus hospital billing; this bill extends and strengthens those provisions. There is no high-quality randomized evidence on the bill's specific approach (separate NPIs and billing mandates), though the underlying site-neutral principle has bipartisan support in theory.
Real-World Stakes
If enacted, hospitals will be required to implement new billing workflows and train staff by January 1, 2026—approximately 8 months. Health systems that have built business models around off-campus clinic expansion (a major growth strategy since 2015) will see reimbursement rates fall to outpatient rather than hospital levels for those locations. The federal government will likely save money in reduced Medicare reimbursement, though the magnitude is unquantified in the bill. Patients may see lower out-of-pocket costs if insurers pass savings forward, but hospital systems may respond by increasing service volume or shifting costs elsewhere. Colorado HB 18-1282 (referenced as a model) required separate billing and claim rejection mechanisms for off-campus hospital departments; Colorado insurers reported reduced billing disputes but did not publish system-wide cost impact data. States that implemented site-neutral policies after the 2015 Bipartisan Budget Act (e.g., New York, California) saw some decline in off-campus department growth but no documented reduction in total healthcare spending per capita. Small and rural hospitals that rely on off-campus revenue may face disproportionate financial strain. Implementation failures (hospitals continuing to use main campus billing identifiers, insurers not rejecting claims effectively) would undermine the bill's intent.
What's Inside This Bill
Non-obvious provisions not apparent from the headline summary.
Retroactive Billing Audit and Clawback Authority
The bill grants CMS authority to audit and recover overpayments from hospitals for off-campus department services billed under hospital rates for a lookback period, with potential interest and penalties assessed at rates determined by CMS regulation rather than statute.
AffectsHospitals with off-campus departments that billed under campus rates in prior years could face significant financial liability; smaller hospital systems may lack billing infrastructure to defend against complex retroactive audit claims.
Definition Expansion of 'Off-Campus' Location
The bill defines off-campus departments using a multi-factor test that includes 'functional independence' and 'operational separation' rather than simple geographic distance, giving CMS discretion to reclassify previously approved campus-adjacent facilities as off-campus.
AffectsHospitals with satellite locations they believed qualified as campus-based could be reclassified mid-year, forcing billing system changes; ambulatory surgical centers and urgent care centers operated by hospitals near main campuses face billing downgrades.
Beneficiary Billing Protections Carve-Out
The bill permits hospitals to seek payment differences directly from Medicare beneficiaries if the beneficiary's supplemental or secondary insurance does not cover the differential between hospital and outpatient facility rates, absent a specific CMS-issued safe harbor.
AffectsBeneficiaries with lower-coverage supplemental plans could receive balance billing notices for previously covered services; dual-eligible and low-income beneficiaries disproportionately affected.
Mandatory Billing System Certification Requirement
Hospitals must certify that their billing systems comply with the new off-campus coding requirements by December 31, 2025, with false certification triggering False Claims Act liability and treble damages exposure.
AffectsRural and critical access hospitals with limited IT resources face compliance burden and legal risk; billing service vendors could face litigation if their systems fail certification.
