Missouri health-insurance questions blend national medical-plan design with a layer of Missouri-specific continuation, conversion, and mandated-benefit rules. This guide reviews the building blocks every health agent needs—plan types and cost-sharing—then makes the Missouri overlay the spine: the state's group continuation ("mini-COBRA"), the conversion privilege, Medicaid through MO HealthNet, and the policy provisions the Missouri Department of Commerce & Insurance (DCI) enforces.

The national base: types of medical plans

Most health questions begin with how a plan balances cost, choice, and network:

• Indemnity / fee-for-service — pays a share of covered charges with broad provider choice; now uncommon.
• HMO (Health Maintenance Organization) — lowest cost, network-only care through a primary care physician (PCP) who acts as a gatekeeper with referrals to specialists; often paid by capitation.
• PPO (Preferred Provider Organization) — a network with lower in-network cost but out-of-network access, usually without referrals.
• EPO (Exclusive Provider Organization) — network-only like an HMO but typically no PCP/referral requirement.
• POS (Point of Service) — a hybrid using a PCP gatekeeper like an HMO while allowing out-of-network care like a PPO.

Universal cost-sharing terms apply across all designs: the premium (what you pay to have coverage), the deductible (paid before the plan shares), the copay (a flat per-visit charge), coinsurance (a percentage split after the deductible, e.g., 80/20), and the out-of-pocket (OOP) maximum (the annual cap after which the plan pays 100% of covered, in-network care). A high-deductible health plan (HDHP) pairs lower premiums with higher deductibles and can be combined with a tax-advantaged Health Savings Account (HSA); an FSA lets employees set aside pretax dollars for eligible expenses. Coverage is also sold group (employer-sponsored via a master policy with employee certificates, lower cost, limited or no individual underwriting) versus individual (bought directly, now guaranteed issue under federal law).

The ACA floor (federal minimums)

The Affordable Care Act sets a national floor every Missouri plan must meet:

• Guaranteed issue — insurers cannot decline an applicant for health reasons.
• No health rating — premiums vary only by age, geography, tobacco use, and family size, not health status.
• Pre-existing conditions covered — no exclusions or waiting periods for prior conditions.
• Essential health benefits — ten required categories (e.g., hospitalization, maternity, prescriptions, mental health, preventive care).
• Dependents to age 26 — adult children may stay on a parent's plan.

Missouri builds on top of this floor; it does not subtract from it.

Missouri mandated benefits

Like every state, Missouri requires insured (non-self-funded) health plans to include certain state-mandated benefits that often exceed the federal minimum. Treat these by category rather than memorizing dollar caps, which change:

• Mental health and substance use coverage consistent with parity rules.
• Mammography and other cancer screenings; childhood immunizations.
• Maternity and newborn care, including minimum post-delivery stays.
• Diabetes self-management, supplies, and education.
• Autism spectrum disorder treatment, subject to statutory limits.

Self-funded ERISA plans are generally exempt from state mandates—a common exam distinction.

Missouri group continuation ("mini-COBRA")

Federal COBRA applies to employers with 20 or more employees and allows continuation generally up to 18 months (or 36 months for certain events such as divorce, death, or a dependent aging out). Missouri fills the gap below the federal threshold with its own group continuation law, often called "mini-COBRA":

• Who: employees of small employers under 20 who therefore are not covered by federal COBRA.
• Eligibility: generally requires a period of prior continuous coverage (verify the current figure).
• How long: Missouri continuation runs for a limited period that is shorter than federal COBRA (frequently cited as a number of months—verify the current duration).
• Cost: the participant pays the full premium themselves.
• Notice/election: the employee must elect within the statutory window after notice of the right.

The exam loves the size split: 20+ employees → federal COBRA; under 20 → Missouri mini-COBRA.

Conversion privilege

Separate from continuation, Missouri group health coverage generally carries a conversion privilege. When group coverage (or continuation) ends, the insured may convert to an individual policy on a guaranteed-issue basis—without new evidence of insurability. Conversion coverage may offer narrower benefits, but it preserves access. On the exam, distinguish continuation (keeping the same group plan temporarily) from conversion (moving to an individual policy).

Missouri Medicaid (MO HealthNet) and the ACA marketplace

• Medicaid in Missouri is called MO HealthNet, administered by the Department of Social Services (MO HealthNet Division)—the income- and asset-based public program (distinct from Medicare). Social Services, not the DCI, runs MO HealthNet, and Missouri has implemented Medicaid expansion (verify current eligibility rules).
• The ACA marketplace in Missouri is the federally facilitated exchange at HealthCare.gov, rather than a state-run exchange (verify the current operational status).

Required policy provisions and timelines

The Missouri DCI enforces standard health-policy provisions, many drawn from the Uniform Individual Accident & Sickness Policy Provisions, including:

• Entire contract — the policy plus the attached application form the whole agreement.
• Grace period — extra time to pay a late premium before the policy lapses (length varies by payment mode).
• Time limit on certain defenses — like incontestability, it restricts contesting the policy (often after 2 or 3 years) for misstatements.
• Reinstatement, notice of claim, claim forms, proof of loss, time of payment of claims, and legal actions provisions govern the claim process.
• Free look — a window (commonly cited around 10 days for many health policies) to return the policy for a full refund; verify the exact figure.
• Outline of coverage — commonly required at delivery for individual health policies.

Key Missouri numbers to memorize

Common exam traps

• Confusing COBRA and mini-COBRA. Federal COBRA = 20+ employees; Missouri mini-COBRA covers employers under 20.
• Mixing up continuation and conversion. Continuation keeps the group plan temporarily; conversion moves to an individual policy with no new evidence of insurability.
• Sending Medicaid questions to the DCI. Missouri Medicaid is MO HealthNet, run by the Department of Social Services.
• Assuming the ACA floor can be undercut. Guaranteed issue, no health rating, and pre-existing coverage are federal minimums Missouri cannot reduce.
• Asserting exact mandate caps or durations. Treat figures as statutory and subject to change—hedge.
• Forgetting self-funded ERISA plans are usually exempt from state mandates.

Quick recap

Missouri medical-plan questions start with national design—HMO, PPO, EPO, POS, and indemnity—and the universal cost-sharing terms (premium, deductible, copay, coinsurance, OOP max), plus the ACA floor: guaranteed issue, no health rating, pre-existing coverage, essential health benefits, and dependents to age 26. The Missouri overlay is the spine: mini-COBRA continuation for employers under 20 (where federal COBRA's 20+ rule does not reach), a conversion privilege to individual coverage on a guaranteed-issue basis, Medicaid through MO HealthNet, and the HealthCare.gov marketplace. Round it out with required provisions the DCI enforces—entire contract, grace period, time limit on defenses, ~10-day free look, and the standard claim provisions—and verify any specific number, and the Missouri health section becomes manageable.
