Medicaid And Hospital Stays: What's The Connection?

Medicaid is a joint federal and state program that helps cover medical costs for certain low-income people, including families, children, pregnant women, the elderly, and people with disabilities. It is funded by both federal and state governments and administered by individual states, with eligibility criteria varying from state to state. While Medicaid typically covers inpatient hospital services, including overnight or longer stays, the specific services covered and the length of coverage for hospital stays can vary depending on the state and the individual's Medicaid plan. Understanding the extent of Medicaid coverage for hospital stays is crucial for beneficiaries, as it can impact their access to necessary healthcare services.

Medicaid coverage for hospital stays is not limited to a specific duration

Medicaid is a joint federal and state program that covers medical costs for certain low-income individuals, families, children, pregnant women, the elderly, and people with disabilities. It also covers medical costs for other adults. While the specific services covered by Medicaid may vary by state and the individual's plan, it typically includes hospital stays, doctor visits, prescription medications, and more.

However, it is important to note that Medicaid coverage for inpatient hospital services is subject to certain limitations and exceptions. For example, prior authorization may be required for non-emergency hospital stays to ensure that the services are medically necessary. There may also be length-of-stay restrictions in some cases. These limitations and exceptions can vary depending on the state and the individual's Medicaid plan.

As of 2025, Medicaid accounts for one-fifth of healthcare spending and more than half of spending on long-term care. It is a major source of funding for the US healthcare system, covering 19% of all healthcare spending and hospital spending. Medicaid expansion has been identified as a factor that will influence hospitals' financial viability in the future.

To determine if Medicaid covers hospital stays in a specific state, it is important to review the eligibility criteria, application process, and specific limitations or exceptions of the Medicaid plan in that state. This information can be obtained from the state's Medicaid agency or online resources.

Medicaid eligibility criteria and income limits

Medicaid is a joint federal and state program that provides health coverage to over 77.9 million Americans, including children, pregnant women, parents, seniors, and individuals with disabilities. To be eligible for Medicaid, individuals must meet specific criteria, including financial and non-financial requirements.

Financial Eligibility Criteria

Financial eligibility for Medicaid is typically determined based on income and assets. The income limits vary by state, type of Medicaid, and the applicant's marital status. For example, Nursing Home Medicaid may have a different income limit than Medicaid Home and Community-Based Services. Additionally, some states have more restrictive eligibility criteria than others.

During the pandemic, some states, like Minnesota, suspended the asset limit for Medical Assistance (MA) eligibility. However, asset limits typically apply, and individuals with more assets than the limit may still have options, such as working with a Certified Medicaid Planner. Assets considered for Medicaid eligibility may include cars, checking and savings accounts, financial investments, and in some cases, an individual's home.

Non-Financial Eligibility Criteria

Non-financial eligibility criteria for Medicaid include factors such as age, residency, citizenship or immigration status, and health or disability status. For example, young adults who are former foster care recipients are eligible for Medicaid at any income level. Additionally, children with adoption assistance agreements under Title IV-E of the Social Security Act are automatically eligible.

Income Limits by State

Medicaid income limits vary by state, and individuals can refer to their state-specific guidelines to determine their eligibility. For instance, Minnesota has published income guidelines for 2025, and households above 200% of the federal poverty guidelines may qualify for a tax credit. However, it's important to note that these guidelines are approximate, and completing an application is necessary to determine actual eligibility.

Supplemental payments and policy changes

Medicaid is a joint federal and state program that covers medical costs for certain low-income groups, including families and children, pregnant women, the elderly, and people with disabilities. It is jointly financed by states and the federal government but administered by states within broad federal rules. While all states are required to provide some Medicaid benefits, many others are optional, including vision services, dental care, and most home care. The rules around eligibility differ across states, with each state setting its own income limits.

Medicaid payments to hospitals play a significant role in providers' finances, impacting beneficiaries' access to care. Historically, Medicaid payments have been below costs, resulting in payment shortfalls. However, these payments are often supplemented by Disproportionate Share Hospital Payments (DSH) and other supplemental payments, which can result in hospitals receiving excess compensation. State budget pressures have led to an increasing reliance on supplemental payments, but upcoming policy changes aim to reduce and restrict their use, causing concern among hospitals dependent on this revenue. Federal officials argue that reforms are necessary to increase transparency, target payments more effectively, and align with delivery system reforms to reduce healthcare costs and improve access to care.

To address funding shortfalls, some states have expanded coverage of behavioral health services and benefits to tackle social determinants of health, such as nutrition and housing. Additionally, nine states have used Medicaid Section 1115 demonstration waivers to fund state uncompensated care pools, with the intention of supporting services for Medicaid beneficiaries, low-income uninsured individuals, and promoting provider participation.

While Medicaid coverage for hospital stays is not limited to a specific duration, it depends on medical necessity and the individual's healthcare needs. Prior authorization may be required for non-emergency hospital stays, and coverage for inpatient hospital services is subject to limitations and exceptions, including length of stay restrictions. Medicaid also covers outpatient hospital services, which are medical services received without an overnight admission. Understanding the specific services covered under an individual's Medicaid plan is crucial for making informed healthcare decisions.

Medicaid beneficiaries' access to care

Ensuring beneficiaries can access covered services is a critical function of the Medicaid program. In 2021, Executive Order 14009 established the policy objective to protect and strengthen Medicaid and the Affordable Care Act (ACA) and to make high-quality healthcare accessible and affordable for every American. The following year, Executive Order 14070 directed agencies to identify ways to continue to expand the availability of affordable health coverage, improve the quality of coverage, strengthen benefits, and help more Americans enrol in quality health coverage.

Medicaid payments to hospitals and other providers play an important role in these providers' finances, which can, in turn, affect beneficiaries' access to care. States have a great deal of discretion to set payment rates for hospitals and other providers. Like other public payers, Medicaid payments have historically been (on average) below costs, resulting in payment shortfalls. However, hospital payment rates are often bolstered by additional supplemental payments in the form of Disproportionate Share Hospital Payments (DSH) and other supplemental payments. After accounting for these payments, many hospitals receive Medicaid payments that may be in excess of costs.

The volume of Medicaid beneficiaries enrolled in a managed care program has grown from 81% in 2016 to 85% in 2021, with 74.6% of Medicaid beneficiaries enrolled in comprehensive managed care organizations. The remaining individuals received all of their care or some services carved out of managed care through FFS. Current access regulations are neither comprehensive nor consistent across delivery systems or coverage authorities. For example, regulations relating to access to care, service payment rates, and Medicaid provider participation in rate-setting apply only to certain types of care delivery systems.

The Ensuring Access to Medicaid Services Final Rule (CMS-2442-F) takes a comprehensive approach to improving access to care, quality, and health outcomes, and better addressing health equity issues in the Medicaid program across fee-for-service (FFS), managed care delivery systems, and home and community-based services (HCBS) programs. These improvements increase transparency and accountability, standardize data and monitoring, and create opportunities for states to promote active beneficiary engagement in their Medicaid programs, with the goal of improving holistic access to care.

Medicaid coverage for emergency room visits

Medicaid is a partnership between federal and state agencies, with the federal government establishing nationwide regulations and providing funding for the program. While laws require that all states' Medicaid programs cover outpatient hospital services, including emergency room visits, the way this care is covered can vary by state. For example, some states may exclude certain services performed in an ER from coverage and require you to pay out of pocket. Some states have also established copay policies, which can be a flat fee or a percentage of the Medicaid reimbursement amount. For instance, the copay for an ER visit was $3 in Mississippi and $4 in Oklahoma.

It's important to note that states have discretion in setting payment rates for hospitals and other providers, and Medicaid payments have historically been below costs, resulting in payment shortfalls. However, hospital payment rates are often supplemented by additional payments, such as Disproportionate Share Hospital Payments (DSH). After accounting for these supplemental payments, many hospitals may receive Medicaid payments that exceed their costs.

In certain situations, a state Medicaid program must provide coverage and care to a beneficiary from another state. This typically occurs when the necessary services and resources are more readily available in the visiting state or when it is common for beneficiaries in one area to receive medical services in a bordering state.

States may also impose specific requirements for Medicaid coverage of emergency room visits. For example, some states mandate prior approval or a "medically necessary" designation by a doctor. Understanding the specific rules and requirements of your state's Medicaid program is essential, as is knowing how much your test, item, or service will cost. While Medicaid coverage for emergency room visits is guaranteed by law, the specific financial details can vary significantly depending on your location and the nature of the treatment provided.
