Health Insurance Basics

  • Risk pooling spreads individual loss costs across a group; the premium equals expected claims plus expenses, reserves, and margin.

  • Insurable risk requires a large number of similar exposure units, accidental and measurable loss, and losses that are not catastrophic to the insurer.

  • Indemnity principle: benefits restore the insured to approximate pre-loss financial position, not profit; this underlies benefit limits and coordination.

  • Adverse selection occurs when higher-risk individuals buy more coverage; underwriting, waiting periods, and exclusions are common countermeasures.

  • Moral hazard is behavior change caused by having coverage; deductibles and coinsurance shift cost to the insured to reduce it.

  • Premium = pure premium (expected claims) + expense loading + risk/contingency margin; loss ratio = incurred claims divided by earned premium.

  • Law of large numbers: as group size grows, actual loss experience converges toward expected experience, improving rate predictability.

  • Reinsurance transfers catastrophic or excess risk from a primary insurer to a reinsurer; it does not directly insure the individual member.

Health Insurance Policy Provisions

  • Entire contract clause: the policy plus attached endorsements and the application constitute the whole agreement; agents cannot orally modify it.

  • Incontestability: after the policy has been in force typically two years, the insurer cannot void coverage for misstatements except fraudulent ones or nonpayment.

  • Grace period: premium may be paid after due date without lapse; typically 7 days (weekly), 10 days (monthly), or 31 days (other modes).

  • Reinstatement provision restores a lapsed policy on evidence of insurability and payment of overdue premium; new contestable period may apply to statements.

  • Free-look provision allows the policyholder to return the policy within a stated period (commonly 10-30 days) for a full premium refund.

  • Coordination of benefits determines order of payment when a person is covered by multiple plans; the primary plan pays first, the secondary pays the balance.

  • Pre-existing condition limitation restricts coverage for conditions treated or diagnosed before the effective date; HIPAA limits its use for creditable coverage groups.

  • Claim provisions require written proof of loss within a stated period (often 90 days) and payment within a stated period (often 30-45 days) after proof.

Health Insurance Providers and Products

  • Indemnity (fee-for-service) plans pay a percentage of covered charges after deductible; insured may use any provider but bears balance billing.

  • HMO: closed panel, gatekeeper primary care, capitation-style provider payment, generally no out-of-network coverage except emergencies.

  • PPO: network of contracted providers with discounted rates; in-network care costs less, out-of-network allowed with higher cost sharing.

  • POS plan blends HMO and PPO features: in-network care managed by a PCP, out-of-network care permitted with referral and higher cost sharing.

  • HDHP paired with an HSA requires minimum deductible and maximum out-of-pocket limits set annually; HSA funds are tax-advantaged and portable.

  • Disability income insurance replaces a percentage of income (commonly 50-70%); own-occupation is broader than any-occupation definition.

  • Long-term care covers custodial care for chronic conditions; benefit triggers typically include inability to perform 2 of 6 ADLs or cognitive impairment.

  • Critical illness and accident policies pay lump sums on defined events; they are supplemental and do not coordinate like major medical coverage.

Government Health Insurance Programs

  • Medicare Part A covers inpatient hospital, skilled nursing facility, hospice, and some home health; financed through payroll taxes.

  • Medicare Part B covers physician and outpatient services; Part C (Medicare Advantage) delivers A and B benefits through private plans; Part D covers prescriptions.

  • Medicare eligibility generally begins at age 65 with sufficient work history, or through disability after 24 months of Social Security disability benefits.

  • Medicaid is jointly funded by federal and state governments, state-administered, and income/asset tested; eligibility varies by state.

  • CHIP provides coverage to low-income children whose family income exceeds Medicaid thresholds but is below state limits.

  • TRICARE provides health coverage to active duty, retired military members, and eligible dependents; VA covers eligible veterans separately.

  • COBRA allows continuation of group coverage after a qualifying event for up to 18 months (29 months if disabled), with the individual paying full premium.

  • HIPAA guarantees portability of group coverage, limits pre-existing condition exclusions for creditable coverage, and protects health information privacy.

Health Insurance Underwriting and Rating

  • Underwriting classifies risk using age, gender, health history, occupation, and lifestyle; the goal is to place applicants in homogeneous rating classes.

  • Field underwriting is the agent's role: complete the application accurately, report known material facts, and collect the initial premium if required.

  • Attending physician statement, medical exam, and prescription history are common underwriting tools for individual health applications.

  • Community rating charges the same rate to all members of a pool regardless of health status; experience rating adjusts rates to a group's own claims.

  • Manual (class) rating uses published rates by class; experience rating and retrospective rating modify rates based on actual group loss experience.

  • Loss ratio = incurred losses divided by earned premiums; a combined ratio above 100% indicates underwriting loss.

  • Rate components include expected claims, administrative expense, commissions, taxes, and a risk/profit margin.

  • Guaranteed renewable policies require renewal at the insured's option with premium increases allowed only by class, not individual health.

Quick reference

Health Insurance Claims and Benefits

  • Claim process: notice of claim, proof of loss, benefit determination, and payment; timely filing limits are stated in the policy.

  • Deductible is the amount the insured pays before benefits begin; coinsurance is the insured's percentage share after deductible.

  • Out-of-pocket maximum caps the insured's cost sharing for covered in-network services in a benefit period.

  • Usual, reasonable, and customary (URC) limits payment to prevailing charges in a geographic area; charges above URC may be balance billed.

  • Coordination of benefits order: the plan covering the person as employee is primary over the plan covering them as dependent; birthday rule applies to dependent children.

  • Subrogation allows the insurer to recover paid benefits from a third party responsible for the loss.

  • Appeals: internal appeal review by the insurer, then external independent review; ERISA and ACA rules set timelines for group health plans.

  • Explanation of benefits (EOB) itemizes charges, allowed amounts, insurer payment, and patient responsibility; it is not a bill.

Quick reference

Health Insurance Regulation and Ethics

  • McCarran-Ferguson Act leaves insurance regulation primarily to the states; state insurance departments license insurers, agents, and enforce market conduct.

  • State guaranty associations protect policyholders if an insurer becomes insolvent, subject to statutory coverage limits.

  • Producer licensing requires prelicensing education, a state exam, and continuing education; a producer must be licensed in the state where the risk is located.

  • Fiduciary duty: premiums collected on behalf of an insurer are held in trust; commingling with personal funds is prohibited.

  • Twisting is misrepresentation that induces a policyholder to lapse or surrender coverage; churning is replacement solely to generate commissions.

  • Rebating-offering part of the commission or anything of value not in the policy as inducement-is prohibited in most states.

  • NAIC model regulations guide state rules on advertising, replacement, privacy, and unfair trade practices but are not federal law.

  • Unfair claim settlement practices include misrepresenting policy provisions, unreasonable delay, and failing to investigate claims promptly.

Health Insurance Basics (Supplemental)

  • Copayment is a fixed dollar amount per service; coinsurance is a percentage; both are forms of cost sharing distinct from the deductible.

  • A rider or endorsement modifies the base policy; it must be attached and is part of the entire contract.

  • Waiting (elimination) period is the time before benefits begin after the effective date or after a loss occurs.

  • Reserves are funds set aside for incurred but not reported (IBNR) claims and future obligations; adequacy affects solvency.

  • Risk retention means the insured keeps part of the loss exposure (e.g., deductible); risk transfer shifts it to the insurer via premium.

Quick reference

Health Insurance Policy Provisions (Supplemental)

  • Change of beneficiary provisions allow the policyholder to change the beneficiary unless irrevocable designation applies.

  • Legal actions provision sets the minimum time (often 60 days) after proof of loss before the insured may sue the insurer.

  • Time limit on certain defenses limits the insurer's ability to contest statements after a stated period, reinforcing incontestability.

  • Payment of claims provision directs how and to whom benefits are paid, including facility or provider payment where applicable.

  • Insuring clause states the insurer's promise to pay covered benefits in exchange for premium.

  • Consideration clause states the premium and the statements in the application as the basis of the contract.

Health Insurance Providers and Products (Supplemental)

  • Exclusive provider organization (EPO) covers only network providers except emergencies; no referral is required.

  • Group health plans are employer-sponsored and typically guarantee issue during open enrollment; individual plans are medically underwritten in many states.

  • Short-term medical plans offer limited duration coverage with exclusions for pre-existing conditions; they are not ACA-compliant major medical.

  • Hospital indemnity and specified disease policies pay fixed benefits and are not substitutes for comprehensive major medical coverage.

  • Medicare supplement (Medigap) plans fill gaps in Original Medicare cost sharing; plans are standardized by letter in most states.

Quick reference

Health Insurance Underwriting and Rating (Supplemental)

  • Attained-age rating increases premium as the insured ages; issue-age rating sets premium based on age at purchase and does not increase with age.

  • Experience modification adjusts a group's manual premium based on its own loss history relative to expected losses.

  • Premium rate must be adequate (cover losses and expenses), not excessive, and not unfairly discriminatory among similar risks.

  • Risk classification must be based on objective, verifiable factors; arbitrary or unfair discrimination among like risks is prohibited.

  • Occupational classification rates higher-risk jobs; avocations and hazardous hobbies may also affect underwriting.

Quick reference

Health Insurance Claims and Benefits (Supplemental)

  • Incurred but not reported (IBNR) claims are estimated liabilities for losses that occurred but have not yet been submitted.

  • Precertification (prior authorization) requires insurer approval before non-emergency services; failure may reduce benefits.

  • Concurrent review monitors ongoing care to determine medical necessity and continued benefit eligibility.

  • Case management coordinates care for high-cost or chronic conditions to improve outcomes and control costs.

  • Benefit period and calendar year are distinct accumulation periods; deductibles and out-of-pocket maximums usually reset each calendar year.

Quick reference

Health Insurance Regulation and Ethics (Supplemental)

  • ERISA governs employer-sponsored benefit plans and preempts many state laws; it sets fiduciary and reporting standards.

  • ACA market reforms include guaranteed issue, prohibition of pre-existing condition exclusions, and essential health benefits for individual and small group markets.

  • State insurance department market conduct exams review claims practices, advertising, and producer conduct.

  • An agent must not commingle premium funds, must remit premiums promptly, and must disclose commissions and conflicts where required.

  • Privacy rules (HIPAA) limit use and disclosure of protected health information by covered entities and their business associates.

Quick reference

Government Health Insurance Programs (Supplemental)

  • Medicare Advantage plans must provide at least the same benefits as Original Medicare and may offer extra benefits.

  • Medicaid eligibility is based on modified adjusted gross income under ACA expansion in participating states.

  • Workers' compensation provides medical and disability benefits for work-related injuries and is state-regulated.

  • Social Security disability insurance (SSDI) provides income benefits and can lead to Medicare eligibility after the waiting period.
