Sources of revenue for our tenants and operators may include the federal Medicare program, state Medicaid programs, private insurance carriers and health maintenance organizations, among others. Efforts by such payors to reduce healthcare costs will likely continue, which may result in the slower growth in reimbursement rates for certain services provided by some of our tenants and operators, which could have a material adverse effect on us. In addition, the healthcare billing rules and regulations are complex, and the failure of any of our tenants or operators to comply with various laws and regulations could jeopardize their ability to continue participating in Medicare, Medicaid, and other government sponsored payment programs. Moreover, the state and federal governmental healthcare payment programs are subject to state and federal legislative and administrative actions, and changes in reimbursement models may reduce our tenants' and operators' revenues and adversely affect our tenants' ability to make rent payments to us or our operators' ability to operate facilities held in RIDEA structures efficiently, either of which could have a material adverse effect on us. Recently, federal policymakers have announced proposals that may result in significant changes to the healthcare system in the United States, including with respect to government funding of or from Medicaid, which could impact us and certain of our tenants.
The healthcare industry continues to face various challenges, including increased government and private payor pressure on healthcare providers to control or reduce costs. It is possible that our tenants and operators will continue to experience a shift in payor mix away from fee-for-service payors, resulting in an increase in the percentage of revenues attributable to reimbursement based upon value-based principles and quality driven managed care programs, and general industry trends that include pressures to control healthcare costs. The combination of these general industry trends and a shift away from traditional health insurance reimbursement based upon a fee for service payment towards payment based upon quality outcomes have increased the uncertainty of payments.
In addition, the Patient Protection and Affordable Care Act of 2010, or the Healthcare Reform Act, was passed with an intent to reduce the number of individuals in the United States without health insurance and effect significant other changes to the ways in which healthcare is organized, delivered and reimbursed. Included within the legislation is a limitation on physician-owned hospitals from expanding facility capacity, unless the facility satisfies very narrow federal exceptions to this limitation. Therefore, if our tenants are physicians that own and refer to a hospital, the hospital may be limited in its operations and expansion potential, which may limit the hospital's services and resulting revenues and may impact the owner's ability to make rental payments.
Furthermore, the Healthcare Reform Act included new payment models with new shared savings programs and demonstration programs that include bundled payment models and payments contingent upon reporting on satisfaction of quality benchmarks. The new payment models will likely change how physicians are paid for services. These changes could negatively affect some of our tenants and operators, which could have a material adverse effect on us.
On December 22, 2017, the Tax Cuts and Jobs Act of 2017 was signed into law and repealed the individual mandate financial penalty portion of the Healthcare Reform Act beginning in 2019. With the elimination of the individual mandate enforcement mechanism, several states brought suit seeking to invalidate the entire Healthcare Reform Act. On June 17, 2021, the U.S. Supreme Court dismissed this lawsuit without specifically ruling on the constitutionality of the law. However, challenges to the Healthcare Reform Act may continue. If any portion of the Healthcare Reform Act is eventually ruled unconstitutional, our tenants and operators may have more patients and residents who do not have insurance coverage, which may adversely impact the tenants' and operators' collections and revenues. CMS has also taken steps to strengthen accountability for nursing homes participating in the Special Focus Facilities, or SFF, an oversight program designed to monitor poor-performing nursing homes. These measures include increased penalties for SFF nursing homes that fail to improve, additional safety standards that SFF nursing homes must implement, increased communication between CMS and SFF nursing homes and monthly public updates to CMS's SFF List, which highlights facilities with a history of serious quality of care issues. The financial impact of these and any future administrative actions on our tenants and operators could adversely affect a tenant's ability to make rent payments to us or an operator's ability to operate facilities held in RIDEA structures efficiently, either of which could have a material adverse effect on us.
In addition, other legislative changes have been proposed and adopted since the ACA was enacted. These changes included aggregate reductions to Medicare payments to providers of 2% per fiscal year, which went into effect on April 1, 2013, and, due to subsequent legislative amendments to the statute, some of which have changed the 2% amount for specific years or suspended the 2% for specific years, will remain in effect through 2032, unless additional Congressional action is taken. Future governmental actions, including changes to the ACA or a reduction in support for Medicare, Medicaid and other government sponsored payment programs, are difficult to predict and could have a material adverse effect on our financial condition and results of operations, while increased regulatory uncertainty could raise our compliance costs. The financial impact on our tenants and operators could adversely affect a tenant's ability to make rent payments to us or an operator's ability to operate facilities efficiently, either of which could have a material adverse effect on us.
In addition, because we and our tenants may rely on government programs or agencies as a source of funding, we and our tenants may be adversely affected by changes in government spending and funding priorities. Funding from government agencies and reimbursement programs such as Medicare and Medicaid, including the overall availability and reimbursement rates under these programs, often fluctuates and is subject to the political process, which is often unpredictable. For example, federal policymakers have announced proposals to reduce overall healthcare spending, including with respect to Medicaid funding, which could impact our healthcare provider tenants and borrowers. Any reduction in the availability or rate of funding or reimbursement, or delays surrounding the approval of such funding or reimbursement, may adversely impact our tenants' operations or may cause our tenants to cease making rent payment payments to us or delay or forgo leasing space in our properties, which in turn may negatively impact our business, financial condition, or results of operations. In addition, such developments could adversely impact the overall demand for space in our properties.
We cannot predict the ultimate content, timing or effect of any further healthcare reform legislation or the impact of potential legislation on us. We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare services, which may adversely impact our tenants' ability to make rental payments to us or our operators' ability to operate facilities held in RIDEA structures efficiently, either of, which could have a material adverse effect on us.
