Patient Protection and Affordable Care Act (PPACA)

Why This Topic Matters on the Exam

A&H exam: 8 of 75 questions

Questions on this topic test both direct recall and applied understanding. You may be given a real-world scenario and asked to identify the correct product, provision, or regulatory requirement — not just define a term. Candidates who score well on this section understand how concepts interact in practice, not just what they mean in isolation.

Key Concepts

These are the core ideas you need to understand for this topic. Each one represents a concept that can appear on the California CDI licensing exam — either directly tested or embedded in scenario questions.

1. The ACA (Affordable Care Act) uses a metal tier system to standardize individual and small group health plans by their actuarial value — the percentage of covered medical costs the plan pays on average across all enrollees. Bronze plans pay 60% of covered costs (enrollee pays ~40%); Silver plans pay 70% (enrollee pays ~30%); Gold plans pay 80% (enrollee pays ~20%); Platinum plans pay 90% (enrollee pays ~10%). Higher-tier plans have higher monthly premiums but lower out-of-pocket costs when you use medical services. The right tier depends on how much healthcare you expect to use and your financial ability to pay out-of-pocket costs.
2. The ACA requires all individual and small group health plans sold in the U.S. to cover 10 Essential Health Benefits (EHBs): (1) ambulatory (outpatient) patient services, (2) emergency services, (3) hospitalization, (4) maternity and newborn care, (5) mental health and substance use disorder services, (6) prescription drugs, (7) rehabilitative and habilitative services and devices, (8) laboratory services, (9) preventive/wellness services and chronic disease management, and (10) pediatric services including oral and vision care. Importantly, ACA plans cannot impose annual or lifetime dollar limits on any EHB — coverage continues no matter how expensive the ongoing treatment becomes.
3. Guaranteed issue is one of the ACA's most transformative rules: insurers in the individual and small group markets cannot deny coverage to any applicant based on pre-existing health conditions, current health status, claims history, or any other health-related factor. Before the ACA, a person with cancer, diabetes, or a prior serious illness could simply be refused individual health insurance. Under the ACA, every applicant must be accepted — and premium variation is only allowed based on age, geographic area, tobacco use, and plan metal tier. This protection applies to all ACA-compliant plans sold in California.
4. The ACA requires health insurance plans that cover dependent children to allow those dependents to remain on a parent's plan until age 26 — regardless of whether the young adult is in school, married, financially dependent on the parent, or living at home. This rule applies to all individual and group health plans that offer dependent coverage, with no exceptions. The young adult's own availability of employer-sponsored coverage is not relevant — they can stay on the parent's plan even if their employer offers coverage. At age 26, they lose eligibility for the parent's plan and have a Special Enrollment Period to obtain their own coverage.
5. Medi-Cal is California's Medicaid program — free or low-cost health coverage for low-income Californians. Under the ACA's Medicaid expansion (which California adopted), adults aged 19 to 64 with household income up to 138% of the Federal Poverty Level (FPL) qualify for Medi-Cal at no cost. Children under 19 can qualify at income levels up to 266% FPL. People who qualify for Medi-Cal are generally not eligible for premium subsidies through Covered California — they go directly into Medi-Cal instead. Understanding the Medi-Cal threshold helps agents guide clients to the right program.
6. APTCs (Advanced Premium Tax Credits) are federal subsidies that reduce the monthly premium cost of health insurance purchased through Covered California (the state exchange). APTCs are available to households with income between 100% and 400% of the Federal Poverty Level (FPL), and due to extensions from the American Rescue Plan Act (ARPA) and Inflation Reduction Act (IRA), households above 400% FPL can also receive credits through 2025. The credit is paid directly to the insurer — reducing the premium the enrollee must pay each month. If the enrollee's actual income at year-end differs from what they estimated, the APTC is reconciled on their tax return.
7. CSRs (Cost Sharing Reductions) are additional subsidies available to Covered California enrollees with household income between 138% and 250% of FPL. CSRs reduce the deductibles, copayments, and out-of-pocket maximums the enrollee must pay — making care significantly more affordable when actually using medical services. The critical rule: CSRs are only available on Silver plans. An eligible enrollee who chooses a Bronze, Gold, or Platinum plan instead of Silver will receive no CSR benefit, even if their income qualifies them. Agents must make sure income-eligible clients choose Silver to access this important additional subsidy.
8. The MLR (Medical Loss Ratio) is the ACA's requirement that health insurers spend a minimum percentage of premium revenue on actual medical care (claims and quality improvement activities). Individual and small group market insurers must maintain an MLR of at least 80% — meaning at least 80 cents of every premium dollar must go toward medical care, not administrative costs and profit. Large group market insurers must maintain an 85% MLR. If an insurer fails to meet the MLR threshold in a given year, it must rebate the excess to policyholders. MLR rules promote efficiency and limit administrative overhead.
9. Agents who want to sell Qualified Health Plans (QHPs — the ACA-compliant health plans sold through Covered California) must complete a separate Covered California agent certification in addition to holding a valid California health insurance license. The certification involves training on ACA rules, subsidies, and enrollment processes. Without this certification, an agent with a valid health license cannot assist clients with Covered California enrollment. The certification must be renewed each year. This is a distinct requirement from the standard California insurance license.
10. CCSB (Covered California for Small Business) is the small employer health insurance exchange where businesses with 2 to 50 employees can shop for group health plans. Employers can offer employees a choice among multiple carriers and metal tiers. Small businesses with 25 or fewer full-time equivalent employees (FTEs) and average wages below an IRS threshold may qualify for the federal Small Business Health Care Tax Credit — worth up to 50% of the employer's premium contribution — but only if coverage is purchased through CCSB. The credit phases out as employer size and average wages increase.
11. The OEP (Open Enrollment Period) is the annual window during which individuals can enroll in or change their Covered California health plan for the upcoming plan year. California's OEP runs from November 1 through January 31 (California has an extended window compared to most states). Outside of OEP, enrollment is only allowed during a Special Enrollment Period (SEP), which is triggered by a qualifying life event such as losing other coverage, getting married, having a baby, moving to a new service area, or gaining citizenship. Without a qualifying event, individuals who miss OEP must wait until the next annual enrollment window.
12. California has its own individual health insurance mandate (effective 2020), separate from the federal mandate. California residents who do not maintain Minimum Essential Coverage (MEC — any ACA-compliant health plan, Medicare, Medicaid/Medi-Cal, or certain other qualifying coverage) must pay a state tax penalty when filing their California state income tax return. The penalty is the greater of: $850 per uninsured adult ($425 per uninsured dependent under 18 per year), or 2.5% of household income above the California filing threshold. The state mandate gives California residents an additional financial incentive to maintain coverage beyond the federal requirement.
13. The American Rescue Plan Act (ARPA, 2021) and Inflation Reduction Act (IRA, 2022) temporarily expanded eligibility for APTCs (Advanced Premium Tax Credits). Normally, APTCs are only available to households with income between 100% and 400% FPL. Under ARPA and IRA extensions, households above 400% FPL also became eligible for credits — with no upper income cap — through the end of 2025. This means even higher-income individuals and families who would otherwise buy coverage on their own may qualify for reduced premiums through Covered California. Agents should check APTC eligibility for all clients, not just those below 400% FPL.
14. ACA-compliant health plans are required to cover a list of preventive services with absolutely no cost-sharing — no deductible, no copay, no coinsurance — when provided by in-network providers. Covered preventive services include: USPSTF (U.S. Preventive Services Task Force) A- and B-rated recommendations (such as certain cancer screenings, blood pressure checks, and HIV screening); ACIP (Advisory Committee on Immunization Practices) recommended vaccines; and a set of women's preventive services and pediatric preventive care guidelines. The intent is to remove cost as a barrier to getting preventive care that catches diseases early and reduces long-term healthcare costs.
