Examples of U.S. health policies include the Affordable Care Act, Medicare, Medicaid, HIPAA, COBRA, the No Surprises Act, the Mental Health Parity and Addiction Equity Act, EMTALA, FDA drug and device rules, and environmental laws like the Clean Air Act. These are the federal laws and programs that decide how you get medical care, what your insurance has to cover, how your health information is protected, and what happens when you can’t pay or your provider is out of network. The list below walks through the biggest ones and what each does for you.
Rules That Shape Private Health Insurance
The Affordable Care Act (ACA), signed in 2010, is the single largest set of rules governing private coverage. Its best-known protection stops insurers from denying you coverage or charging you more because of a pre-existing condition.1HHS.gov. Pre-Existing Conditions Before the ACA, individual-market insurers routinely did both.
Non-grandfathered individual and small-group plans must cover ten categories of essential health benefits:2Office of the Law Revision Counsel. 42 USC 18022 – Essential Health Benefits Requirements
- Outpatient care
- Emergency services
- Hospitalization
- Maternity and newborn care
- Mental health and substance use disorder treatment
- Prescription drugs
- Rehabilitative and habilitative services and devices
- Laboratory services
- Preventive and wellness services and chronic disease management
- Pediatric services, including dental and vision
Most plans also have to cover a defined set of preventive services with no copay, coinsurance, or deductible when you see an in-network provider, covering things like immunizations and screening tests.3HealthCare.gov. Preventive Health Services
On the employer side, the ACA requires businesses with 50 or more full-time equivalent employees to offer affordable coverage that meets a minimum value standard to at least 95 percent of their full-time workforce. For 2026, affordable means the employee’s share of the lowest-cost self-only premium can’t exceed 9.96 percent of household income, and a plan meets minimum value when it covers at least 60 percent of total allowed costs. Employers that fall short face penalties of $3,340 per full-time employee under the general coverage requirement, or $5,010 per full-time employee who ends up getting subsidized marketplace coverage because the employer’s plan didn’t qualify.
The law also created the health insurance marketplaces where you can shop for coverage and receive premium tax credits based on income. Enhanced subsidies that had been in place since 2021 expired at the start of 2026, so the income cap for eligibility reverted to 400 percent of the federal poverty level and household contribution percentages went up.4Congressional Research Service. Enhanced Premium Tax Credit and 2026 Exchange Premiums
Government-Run Insurance Programs
Several federal programs cover people who would otherwise go without care. Each targets a different group.
Medicare
Medicare covers people 65 and older, and younger people with certain disabilities, End-Stage Renal Disease, or ALS.5Medicare.gov. Get Started with Medicare Most people pay no premium for Part A because they or a spouse paid Medicare taxes for at least 10 years.6Medicare.gov. Medicare Costs The program has four parts: Part A for hospital, skilled nursing, hospice, and some home health; Part B for outpatient care, physician services, and medical equipment; Part C (Medicare Advantage) for receiving Parts A and B through a private plan, often with added vision or dental; and Part D for prescription drugs.
Starting in 2026, negotiated prices took effect for the first ten drugs selected under the Medicare Drug Price Negotiation Program, created by the Inflation Reduction Act. If those prices had applied during 2023, Medicare would have saved an estimated $6 billion in net prescription drug costs, and enrollees are projected to save roughly $1.5 billion under the new prices.7Centers for Medicare & Medicaid Services. Negotiated Prices for Initial Price Applicability Year 2026
Medicaid and CHIP
Medicaid is a federal-state partnership that covers low-income individuals and families. States run their own programs within federal guidelines and receive federal matching funds.8Medicaid.gov. Eligibility Policy Federal law requires states to cover certain groups, including low-income families, qualified pregnant women and children, and people receiving Supplemental Security Income. The ACA also gave states the option to expand Medicaid to most low-income adults under 65.
The Children’s Health Insurance Program (CHIP) covers kids in families who earn too much for Medicaid but can’t easily afford private coverage.9Medicaid.gov. CHIP Eligibility and Enrollment Every state’s CHIP program must cover well-child care, dental, behavioral health, and vaccines.10Centers for Medicare & Medicaid Services. CHIP Fact Sheet
VA Health Care
The Veterans Health Administration covers eligible veterans who served in the active military, naval, or air service and did not receive a dishonorable discharge.11Veterans Affairs. Eligibility for VA Health Care Eligible veterans receive most care and services, though certain added benefits like dental are limited to specific groups.12Veterans Affairs. About VA Health Benefits
Health Coverage Tied to Your Job
Federal law also controls what your employer plan looks like, what happens if you lose your job, and what happens when you take medical leave.
ERISA
The Employee Retirement Income Security Act sets minimum standards for most employer-sponsored plans in private industry. It requires plans to give participants information about features and funding, sets rules for how plan assets are managed, and creates a grievance and appeals process. ERISA also gives you the right to sue for benefits or for breaches of the plan administrator’s duties.13U.S. Department of Labor. ERISA It generally does not cover plans maintained by government entities or churches.
COBRA
COBRA lets you keep employer coverage for a limited time after job loss or a cut in hours. It applies to private-sector employers with 20 or more employees and to state and local government plans.14U.S. Department of Labor. FAQs on COBRA Continuation Health Coverage for Workers After a qualifying event like termination for reasons other than gross misconduct, you get at least 60 days to decide whether to elect coverage. It typically lasts up to 18 months after job loss or reduced hours, and up to 36 months for other qualifying events. A Social Security-recognized disability can extend it to 29 months, though the premium can rise to 150 percent of the plan’s cost during the extension. Otherwise, the premium can’t exceed 102 percent of what the plan costs for similarly situated active employees.
FMLA
The Family and Medical Leave Act does more than protect your job during qualified leave. It requires your employer to keep your group health coverage on the same terms as if you had never left. If you had family coverage before leave, it continues. If the employer changes plans or benefits for active employees while you’re out, you get the same updated coverage.15eCFR. 29 CFR 825.209 – Maintenance of Employee Benefits When you return, you’re entitled to reinstatement without any new qualifying period or pre-existing condition exclusion.
Protection From Surprise Medical Bills
The No Surprises Act took effect in January 2022. It bars surprise bills for most emergency services, including follow-up stabilization care, at out-of-network hospitals and freestanding emergency departments.16Centers for Medicare & Medicaid Services. No Surprises Act Overview of Key Consumer Protections
It also reaches non-emergency care. If you go to an in-network hospital for a scheduled procedure and an out-of-network specialist like an anesthesiologist or radiologist treats you, that provider generally can’t balance-bill you unless they gave you advance written notice and you consented. Out-of-network air ambulance services are covered too; ground ambulance services are not.16Centers for Medicare & Medicaid Services. No Surprises Act Overview of Key Consumer Protections When the law applies, your cost-sharing is calculated at in-network rates, based on the lesser of the provider’s billed charge or a Qualifying Payment Amount tied to the median in-network rate in your area.
Equal Treatment for Mental Health
The Mental Health Parity and Addiction Equity Act (MHPAEA) says health plans that offer mental health or substance use benefits can’t make those benefits harder to access than comparable medical or surgical benefits.17Centers for Medicare & Medicaid Services. The Mental Health Parity and Addiction Equity Act
Copays for therapy have to be comparable to copays for a specialist visit. Visit limits on mental health care can’t be more restrictive than limits on medical visits. Prior authorization for substance use treatment can’t be more burdensome than for surgical care.18U.S. Department of Labor. Mental Health and Substance Use Disorder Parity If the plan covers out-of-network medical care, it has to cover out-of-network mental health and substance use care too. The ACA reinforced this by making mental health and substance use one of the ten essential benefit categories.
Privacy of Your Medical Records
The HIPAA Privacy Rule sets national standards for protecting your medical records and other individually identifiable health information, called protected health information (PHI). It applies to health plans, healthcare providers that transmit information electronically, healthcare clearinghouses, and their business associates.19HHS.gov. Summary of the HIPAA Privacy Rule The rule limits when your health information can be used or disclosed without your authorization, and it gives you the right to see and receive copies of your medical records with limited exceptions.20HHS.gov. Individuals’ Right Under HIPAA to Access Their Health Information 45 CFR 164.524
HIPAA also sets breach notification deadlines. A covered entity has to notify you in writing within 60 days of discovering a breach of unsecured PHI. Breaches affecting 500 or more people also require notice to the HHS Secretary within 60 days and a press release to media in the affected area. Smaller breaches can be reported to HHS annually, no later than 60 days after year-end. Business associates have to notify the covered entity within the same 60-day window.21HHS.gov. Breach Notification Rule
Safety of Drugs, Devices, and Vaccines
The Food and Drug Administration regulates the safety of the medical products you use, mostly under the Federal Food, Drug, and Cosmetic Act, which requires drugs and medical devices to demonstrate safety and effectiveness before sale.22Congressional Research Service. Medical Product Regulation – Drugs, Biologics, and Devices
Medical devices are classified by risk. Class I (low-risk items like tongue depressors) face the lightest controls. Class II (moderate-risk items like powered wheelchairs) have to meet added performance standards. Class III (high-risk items like pacemakers and heart valves) require premarket approval based on valid scientific evidence from clinical trials.23eCFR. 21 CFR Part 860 – Medical Device Classification Procedures
Vaccines go through rigorous review of laboratory and clinical data before approval and may face additional post-market studies on safety, effectiveness, and side effects.24U.S. Food and Drug Administration. Vaccines After approval, FDA and CDC jointly monitor safety through passive systems like the Vaccine Adverse Event Reporting System (VAERS) and active surveillance through large healthcare data systems.25U.S. Food and Drug Administration. COVID-19 Vaccine Safety Surveillance
Public Health and Environmental Rules
Some of the most important health policies never mention doctors or insurance. They keep harmful substances out of the air, water, and consumer products.
The Clean Air Act directs the EPA to set National Ambient Air Quality Standards for pollutants that endanger public health. Six criteria pollutants are currently regulated: ozone, carbon monoxide, sulfur dioxide, particulate matter, nitrogen dioxide, and lead.26Cornell Law School. Clean Air Act (CAA) Each pollutant has to stay below a level that protects public health with an adequate margin of safety.
The Clean Water Act works similarly for water. It prohibits pollutant discharges into U.S. waters from any point source without a National Pollutant Discharge Elimination System (NPDES) permit, which sets facility-specific discharge limits and monitoring rules.27US EPA. NPDES Permit Basics
Federal law also sets the minimum age for buying any tobacco product at 21, with no exception for military members or veterans. It covers cigarettes, e-cigarettes, smokeless tobacco, cigars, hookah, pipe tobacco, and any product containing nicotine regardless of source. Retailers have to check photo ID for anyone who looks under 30, and vending machine sales are banned in any facility where people under 21 are allowed.28U.S. Food and Drug Administration. Tobacco 21
Emergency Room Access and Telehealth
The Emergency Medical Treatment and Labor Act (EMTALA) is why no hospital emergency room can turn you away. Any Medicare-participating hospital with an emergency department has to provide a medical screening exam to anyone who requests care, regardless of ability to pay or insurance status.29Office of the Law Revision Counsel. 42 USC 1395dd – Examination and Treatment for Emergency Medical Conditions and Women in Labor If the exam reveals an emergency condition, the hospital has to stabilize you or arrange an appropriate transfer. Screening and treatment can’t be delayed to check insurance, and you can’t be transferred or discharged before stabilization unless you request it or a physician certifies the benefits outweigh the risks.
Telehealth rules are still in transition. Through December 31, 2027, Medicare beneficiaries can receive telehealth services from anywhere in the United States, without the older geographic restrictions.30Centers for Medicare & Medicaid Services. Telehealth FAQ Starting in 2028, most non-behavioral-health telehealth visits will revert to requiring the patient to be in a medical facility in a rural area. Behavioral health telehealth is permanently exempt from those geographic and location restrictions.
For controlled substances, the Ryan Haight Act normally requires an in-person evaluation before a provider can prescribe through telemedicine. A temporary rule extends COVID-era flexibility through December 31, 2026, allowing prescriptions for Schedule II through V medications without that initial face-to-face visit. If you rely on telehealth for a controlled prescription, plan for that flexibility to expire.
