Massachusetts is the distinctive health-insurance state, so the exam expects you to know the Massachusetts story on top of the national basics. This standalone guide reviews how medical plans work nationally—HMO/PPO/EPO/POS/indemnity, cost-sharing, group vs. individual, and the ACA floor—then makes Massachusetts law the spine: the state pioneered near-universal coverage in 2006 with "Chapter 58," the model the federal ACA later copied, and it still runs an individual mandate, the Health Connector exchange, and MassHealth. Treat the Massachusetts overlay as the centerpiece—it shows up everywhere.

The national base: types of medical plans

Most health questions begin with plan design:

• HMO (Health Maintenance Organization) — care coordinated through a primary care physician (PCP) with referrals; in-network only except emergencies. Prepaid, managed care.
• PPO (Preferred Provider Organization) — a network with lower cost in-network but out-of-network access without referrals.
• EPO (Exclusive Provider Organization) — network-only like an HMO, but usually no referrals required.
• POS (Point of Service) — hybrid: a PCP/referrals like an HMO, but out-of-network allowed at higher cost.
• Indemnity/fee-for-service — traditional reimbursement, use any provider; now rare.

Cost-sharing vocabulary is the same everywhere: premium, deductible, copay, coinsurance, and an out-of-pocket maximum. Coverage is sold to groups (employer plans, with the employer as policyholder and employees as certificate holders) or to individuals.

The ACA floor

Federal law (the Affordable Care Act) sets the minimum every plan must meet:

• Guaranteed issue — insurers must accept eligible applicants.
• No health rating — premiums cannot be based on health status.
• Pre-existing conditions covered — no exclusions or waiting periods.
• Essential health benefits (EHBs) — a defined set of core services every plan must include.
• Dependent coverage to age 26.

Massachusetts meets all of this and then exceeds it, because the state built its own near-universal system before the ACA existed.

The Massachusetts overlay: Chapter 58 and the individual mandate

This is the headline. In 2006, Massachusetts enacted Chapter 58, achieving near-universal coverage and becoming the model for the federal ACA. Two pieces matter most for the exam:

• Individual mandate — Massachusetts requires most adult residents to carry coverage meeting minimum creditable coverage (MCC) standards or face a state tax penalty. This Massachusetts mandate still exists under state law even though the federal ACA penalty was zeroed out—a classic exam point.
• Minimum creditable coverage (MCC) — the state's benchmark for what counts as adequate coverage to satisfy the mandate.

The Massachusetts Health Connector

The state-based marketplace is the Massachusetts Health Connector—the first-in-the-nation health exchange, created under Chapter 58 and copied by the ACA marketplaces nationwide. It is where individuals and small employers shop for plans and where eligible residents access subsidized coverage.

MassHealth (the Medicaid program)

Massachusetts calls its Medicaid program MassHealth—memorize that name. MassHealth covers low-income residents, children, seniors, and people with disabilities, blending federal Medicaid with state-funded programs. On the exam, if a Massachusetts question mentions income-based public coverage, the answer is usually MassHealth.

Mandated benefits

Massachusetts is a strong-mandate state—insured medical plans must cover a long list of services that often exceed the federal floor. You don't memorize the whole list; know the concept and a few representative examples:

• Maternity and newborn care.
• Mental health and substance-use disorder benefits with parity.
• Cancer screenings such as mammography.
• Diabetes supplies and education.
• Infertility/IVF coverage (a long-standing Massachusetts mandate often cited on exams).

If asked whether Massachusetts requires more than federal minimums, the answer is generally yes.

Continuation: mini-COBRA and federal COBRA

When group coverage would otherwise end, employees may continue it:

• Federal COBRA applies to employers with 20 or more employees, generally up to 18 months (longer for disability or certain events).
• Massachusetts "mini-COBRA" (small-group continuation) fills the gap for employers below the federal 20-employee threshold, so small-firm employees still get continuation rights. Treat the exact length as the current statutory figure—commonly cited around 18–36 months depending on the qualifying event; verify.

The memory hook: 20+ → federal COBRA; smaller employers → Massachusetts mini-COBRA.

Conversion privilege

Beyond continuation, Massachusetts preserves a conversion privilege—the right to convert group coverage to an individual policy when continuation ends, without new evidence of insurability. With guaranteed-issue marketplace coverage through the Health Connector, many people now move to a Connector plan instead, but the conversion concept remains a tested fundamental.

Provisions and timelines

Standard health-policy provisions still apply and carry Massachusetts-flavored figures (verify exact current numbers):

• Grace period — time to pay an overdue premium before lapse.
• Free look — right to return a new policy for a refund, commonly 10 days.
• Incontestability — after a set period (commonly 2 years), the insurer generally cannot void the policy for misstatements.
• Prompt-pay — insurers must pay or deny clean claims within set timeframes, with interest on late payments.

Key Massachusetts numbers to memorize

Common exam traps

• Saying the individual mandate is gone. The federal penalty is zero, but the Massachusetts mandate still exists under state law.
• Forgetting Massachusetts came first. Chapter 58 (2006) preceded and modeled the ACA.
• Naming the exchange generically. It is the Massachusetts Health Connector, the first-in-nation exchange.
• Calling Medicaid "Medicaid" on a Massachusetts question. Use MassHealth.
• Applying federal COBRA to a 10-employee firm. Small employers use Massachusetts mini-COBRA.
• Forgetting conversion is without new underwriting.
• Assuming Massachusetts only meets federal minimums. It adds mandated benefits.

Quick recap

Massachusetts medical plans use the national skeleton—HMO/PPO/EPO/POS/indemnity, standard cost-sharing, group vs. individual, and the ACA floor (guaranteed issue, no health rating, pre-existing covered, EHBs, dependents to age 26). But Massachusetts law dominates: Chapter 58 (2006) built near-universal coverage and became the model for the ACA, the individual mandate still exists under state law (meet minimum creditable coverage or pay a state penalty), the marketplace is the first-in-nation Massachusetts Health Connector, and Medicaid is MassHealth. The state adds strong mandated benefits, offers mini-COBRA for small employers below the federal 20-employee COBRA threshold plus a conversion privilege, and enforces standard provisions (grace, free look, incontestability, prompt-pay)—all under the Massachusetts Division of Insurance. Learn the Massachusetts overlay and the medical-plans section becomes reliable points.
