- The Employer-Plan Parallel: What Your Group Insurance Also Must Do
Every ACA-compliant plan — Marketplace, most employer, Medicaid-alternative and exchange-adjacent products — is built on a federal floor called the essential health benefits (EHBs). Knowing that floor turns plan brochures from soup into signals: you can see instantly what is guaranteed, what varies by state benchmark, and what a plan can lawfully leave out. This guide details the ten benefit categories, the 2026 dollar caps, the metal-tier math, and the fine print that decides real-world claims.
The Ten Essential Health Benefits
Congress defined ten categories that every individual and small-group plan must cover. One: ambulatory (outpatient) services — doctor visits, urgent care, outpatient surgery. Two: emergency services, with the federal rule that plans cannot charge more for out-of-network emergency rooms or require prior authorization for screening a true emergency. Three: hospitalization — inpatient care, surgery, overnight stays. Four: maternity and newborn care, before, during and after birth, with no waiting period. Five: mental health and substance-use disorder services, required at parity with medical benefits in both coverage limits and cost sharing. Six: prescription drugs — every plan maintains a formulary covering, at minimum, one drug per category and class in each state’s benchmark. Seven: rehabilitative and habilitative services and devices — physical therapy, speech therapy, prosthetics, and notably habilitation (skills-building for developmental conditions), which pre-ACA plans often skipped. Eight: laboratory services, from blood panels to screenings. Nine: preventive and wellness services plus chronic disease management — the USPSTF A and B screenings, ACIP immunizations and HRSA guidelines, covered with zero cost sharing in-network. Ten: pediatric services including oral and vision care for children.
What the Floor Does Not Standardize
EHBs define categories, not exact scope. Each state chose a benchmark plan defining how much habilitation therapy, how many PT visits, which bariatric surgery indications, and which fertility services (usually none) are included. That is why an autism ABA therapy benefit differs between Nevada and Alabama, and why IVF is a covered benefit almost nowhere on the exchanges. The floor is genuinely strong; the ceiling is state-specific.
The 2026 Out-of-Pocket Maximums
The most consumer-protective number in the statute is the annual out-of-pocket maximum: in 2026, $10,600 for self-only coverage and $21,200 for family. Once your in-network deductibles, copays and coinsurance sum to that figure, the plan pays 100% of in-network essential-benefit costs for the rest of the year. Family plans carry an embedded-versus-aggregate distinction that matters: embedded plans cap each member at the self-only maximum even mid-family-year, while aggregate plans count the family together — check which design your plan uses, because a single catastrophic illness hits differently under each.
Three things do not count toward the cap: monthly premiums, out-of-network charges (in non-PPO designs, unlimited), and non-essential services such as adult dental or cosmetic care. The cap protects against network catastrophe, not against geography.
Metal Tiers: The Actuarial Value Ladder
Plans are labeled by expected cost sharing: Bronze pays about 60% of covered costs for a standard population, Silver 70%, Gold 80%, Platinum 90%. The label is an average, not a promise — your personal share depends on usage. A Bronze plan with a $7,000 deductible behaves like 60% coverage only if you run through the whole deductible; for light users it behaves like a disaster policy, which is precisely its job. Catastrophic plans — available to under-30s and hardship exemptions — carry the $10,600 deductible and three primary-care visits free, functioning as a pure safety net.
Cost-sharing reductions (CSRs) are the hidden fourth tier: households between 100% and 250% of poverty buying Silver receive enhancements that push actuarial value to 73%, 87% or 94% while the Silver label stays. A CSR-94 Silver plan has a lower deductible than most Platinum plans — the single strongest reason lower-income enrollees should filter for Silver rather than chase Bronze’s lower premium.
Preventive Care: The Zero-Dollar Layer
Roughly one hundred services are covered without deductible or copay in-network: annual physicals, blood pressure and cholesterol screening, mammograms from 40, colonoscopy from 45, cervical screening, diabetes and depression screening, all ACIP-recommended vaccines, contraception, and prenatal care protocols. The no-cost guarantee applies to in-network delivery; out-of-network preventive care can be billed normally, and “preventive procedure that turns diagnostic” — a screening colonoscopy where a polyp is removed — can generate cost sharing. The exceptions are documented, not discretionary.
What Compliant Plans May Still Exclude
Grandfathered plans (kept since 2010 without material change) may skip some EHBs. All plans may exclude adult dental and vision (buy separate coverage), long-term care, cosmetic surgery, and — the classic surprise — air ambulance in many designs. Off-exchange but ACA-compliant plans must still carry EHBs and the caps; “non-compliant” products (short-term, fixed indemnity, sharing ministries) carry none of these guarantees and are the source of most horror-story claims.
Using the Floor as a Buying Tool
When comparing plans, verify four numbers against this guide: the out-of-pocket maximum (must not exceed $10,600/$21,200), the metal tier (expect the actuarial value within a few points), the formulary tier of your prescriptions, and the CSR level if income-qualified. A plan that clears all four checks is legally identical in protection to every other plan that does — the differences left are networks, service quality and price, which is exactly the comparison worth spending an hour on.
Reading a Summary of Benefits and Coverage in Three Minutes
Every compliant plan ships a standardized Summary of Benefits and Coverage (SBC), and the standardization is the point: the same six comparison rows appear for every plan in America. Scan in this order: the “common medical events” table — simple fracture, diabetes care, repair of a torn ligament — showing your actual cost under each event; the deductible line, noting whether it is embedded or aggregate for families; the out-of-pocket maximum line against the 2026 caps; the “exclusions” box, which legally must state coverage limitations plainly; the coverage-example page (the standard “peggy” scenario) that quantifies plan generosity on a real $2,200 and $55,000 claim; and the uniform glossary pointer. Two plans with identical metal tiers can differ 30% in the SBC’s torn-ligament row — the row that actually predicts your year. The SBC is a legal document with defined definitions, which makes it the fastest honest comparison tool in the industry and the antidote to brochure adjectives.
Appeals, External Review and the Rights Behind the Benefits
The EHB floor comes with an enforcement ladder. When a plan denies a service as “not medically necessary” or “not a covered benefit,” you first demand the denial reason in writing — plans must state the specific rule applied. Internal appeal: file within 180 days; the plan must acknowledge, allow you to submit supporting records, and decide on a full-and-fair review, with urgent cases decided within 72 hours. External review: if the internal appeal fails, an independent review organization — not the insurer — evaluates clinical necessity under your state’s external review program or the federal IRO process, and its decision binds the plan. Pre-service denials of EHB-categorized care win external review roughly 40% of the time, which makes the paperwork the highest-yield hour in patient advocacy. The floor is only as strong as the claimant who invokes it: keep every EOB, denial letter and call reference number, and remember that “the plan said no” is a procedural event with a next step, not a verdict.
Habilitation, Autism Therapy and the Benefits That Vary Most
The habilitative category — services that help a person acquire skills for the first time, as distinct from rehabilitation after loss — is where state benchmarks diverge most, and where families feel it most. Speech therapy for a toddler with a language delay, applied behavior analysis (ABA) for autism, occupational therapy for developmental coordination: every compliant plan covers the category, but the state benchmark defines visit limits, age bands and medical-necessity criteria. States with strong autism mandates (Indiana, Kansas, New York among the early adopters) push benchmarks toward broad ABA coverage — 25-plus hours weekly where medically necessary — while benchmarks built from lean HMO plans cap habilitation at 20-30 visits per year regardless of diagnosis. The practical navigation: identify your state’s EHB benchmark (published on CMS’s state EHB page), read the habilitation and pediatric lines, and if your child’s needs exceed the benchmark, look for plans that offer state-mandate riders beyond the floor, and pair coverage with school-based services (IDEA Part B services are delivered by school districts at no cost and do not consume insurance visits). Families relocating should treat the habilitation line as a top-three plan criterion — the difference between benchmarks is routinely the difference between coverage for the therapy year and out-of-pocket five-figure spend.
Frequently Asked Questions
Can a plan drop me after a big claim? No. ACA-compliant plans are guaranteed-renewable; cancellation for claims or health status is unlawful.
Is maternity covered on every plan? Yes, as an essential benefit, with no waiting period — including Marketplace, most employer, and Medicaid/CHIP.
What is the worst-case spending in 2026? $10,600 self-only / $21,200 family in-network, after which essential benefits are covered at 100% for the plan year.
Are annual limits legal? Not on essential health benefits — the dollar caps Congress prohibited in 2010 remain fully in force for compliant plans.
Does the out-of-pocket max include premiums? No — premiums, out-of-network charges and non-essential services sit outside the cap by design.
The Employer-Plan Parallel: What Your Group Insurance Also Must Do
The EHB floor applies to nearly all employer plans too, which is why the two markets feel similar at the benefit level. Grandfathered group plans (a shrinking few percent of the market) may skip some categories, and self-insured large employers must cover the categories but may self-fund without state-mandate add-ons. The consumer consequences: your 2026 open-enrollment booklet from work shows the same out-of-pocket caps, the same preventive-care guarantee and the same parity rules as a Marketplace plan; the differences concentrate in network breadth, formulary design and contribution levels. That convergence is deliberate — Congress built one floor for the whole private market precisely so that changing jobs would not change the guarantee. When you compare an employer offer against a Marketplace quote, you are comparing networks and prices, not benefit rights; the statutory floor underneath both is the same slab of concrete.
