What Are Essential Health Benefits?
Under the Affordable Care Act (ACA), every health insurance plan sold on the individual or small group market— including all plans on Healthcare.gov—must cover 10 categories of services known as Essential Health Benefits (EHBs). These are not optional add-ons. They are federally mandated, guaranteed coverage areas.
Texas uses the federal government's "benchmark" EHB standard, meaning plans in Texas must cover the same core benefits as those in most other states. However, the specific services, medications, and providers within each category can vary by plan and carrier.
The 10 Essential Health Benefits
Ambulatory Patient Services
Outpatient care you receive without being admitted to a hospital. Includes doctor visits, clinic care, same-day surgery, and diagnostic services. This is the most frequently used category.
Emergency Services
Trips to the emergency room (ER) for acute conditions. Federal law prohibits prior authorization for ER visits and requires plans to cover emergency care at in-network levels regardless of whether the hospital is in your plan's network. You cannot be charged more for going to an out-of-network ER.
Hospitalization
Inpatient care, including surgeries, overnight hospital stays, and medical procedures. Includes room and board, nursing care, and hospital-based medications during your stay.
Pregnancy, Maternity, and Newborn Care
Complete prenatal care, childbirth services (vaginal and C-section), and postnatal care for mother and baby. All ACA plans must cover maternity and newborn care—even before pregnancy begins. No plan can exclude pregnancy as a pre-existing condition.
Mental Health and Substance Use Disorder Services
Outpatient and inpatient behavioral therapy, counseling, and substance abuse treatment. The Mental Health Parity and Addiction Equity Act (MHPAEA) requires plans to cover mental health and substance use treatment at the same level as physical health care. This means deductibles, copays, and visit limits cannot be more restrictive than those for medical/surgical care.
Prescription Drugs
Coverage for generic and brand-name medications. Every EHB-compliant plan must cover at least one drug in every U.S. Pharmacopeia (USP) therapeutic category and class. This means you can find covered alternatives for most conditions, though specific brand-name drugs may require prior authorization or step therapy.
Rehabilitative and Habilitative Services
Devices and therapies that help people recover from injuries, surgeries, or manage chronic illnesses and disabilities. Includes physical therapy, occupational therapy, speech therapy, and durable medical equipment (wheelchairs, walkers, prosthetics).
Laboratory Services
Diagnostic testing including blood work, urinalysis, pathology, and imaging such as X-rays, MRIs, CT scans, and PET scans. These services are essential for diagnosis and treatment monitoring.
Preventive and Wellness Services
Routine health checks, immunizations, and cancer screenings (mammograms, colonoscopies, Pap smears). These must be covered at 100% with $0 out-of-pocket cost when you see an in-network provider. Includes well-child visits, flu shots, blood pressure screening, cholesterol checks, and depression screening.
Pediatric Services
Medical care for children, including oral (dental) and vision (eye) care. Unlike adult dental and vision—which are not EHBs—pediatric dental and vision are mandatory. This includes routine dental cleanings, fluoride treatments, eye exams, and corrective lenses for dependents under age 19.
What This Means for Texans
If you buy an ACA-compliant plan in Texas—whether on Healthcare.gov or off-exchange—you are guaranteed all 10 EHBs. No lifetime or annual dollar limits apply to these benefits. Your plan cannot drop you for getting sick, and pre-existing conditions must be covered without waiting periods.
What plans DON'T have to cover:
- Adult dental and vision (unless the plan chooses to include it)
- Cosmetic surgery
- Weight loss surgery (unless medically necessary)
- Alternative medicine (acupuncture, chiropractic may be limited)
- Long-term care/nursing home care
How to Verify Your Plan's EHB Coverage
- Request a Summary of Benefits and Coverage (SBC) from your insurer or broker
- Check the plan's drug formulary to see if your medications are covered
- Verify that your preferred doctors and hospitals are in-network
- Ask specifically about mental health parity and habilitative services (these are often under-covered despite legal requirements)
Short-Term Plans vs. ACA Plans: The EHB Gap
Short-term health plans and health sharing ministries are not required to cover EHBs. This is why they cost 50-70% less—but it's also why they can exclude maternity coverage, cap mental health benefits, or refuse pre-existing conditions. If you need comprehensive protection, an ACA-compliant plan is the only way to guarantee all 10 EHBs.
