Health insurance Study Guide

📖 Core Concepts Health insurance: a contract that pays all or part of a person’s medical expenses; risk is spread across a risk pool of many insured individuals. Premium: regular payment (monthly/annual) made by the policyholder or sponsor to obtain coverage. Deductible: the amount the insured must pay out‑of‑pocket before the insurer starts sharing costs. Co‑payment (copay): a fixed fee the insured pays each time a specific service is received (e.g., $45 for a doctor visit). Coinsurance: a percentage of the bill the insured pays after the deductible is met (e.g., 20 % of a surgery cost). Out‑of‑Pocket Maximum: the ceiling on the insured’s total cost‑sharing; once reached, the insurer pays 100 % of further covered expenses. Network: In‑Network: providers with contracts that give discounted rates and lower patient cost‑sharing. Out‑of‑Network: providers without contracts; patients may face full charges plus any cost‑sharing. Prior Authorization: insurer’s pre‑approval required before a service is delivered; guarantees payment for the authorized service. Formulary: the list of prescription drugs that a plan agrees to cover. Explanation of Benefits (EOB): statement from the insurer showing what was covered, amounts paid, and the patient’s remaining responsibility. Public vs. Private Funding: Public plans are financed by taxes or mandatory premiums (e.g., Medicare, NHS, Dutch basic insurance). Private plans are paid by individuals, employers, or a mix of premiums and savings accounts. --- 📌 Must Remember Risk pooling allows insurers to set premiums based on the average risk of the covered population. Under the Affordable Care Act (ACA), premiums are adjusted for age, location, tobacco use, family size, and plan tier; tax credits may offset costs. Capitation: a fixed amount paid by an insurer to a provider for caring for all members of the plan. Netherlands: mandatory basic insurance, same premium for all ages/health statuses, no copays, caps, or deductibles on the basic package; risk‑adjusted payments come from an equalisation pool. Singapore – MediShield Life: covers public‑hospital B2/C wards; private‑hospital or higher‑class wards require supplemental Integrated Shield plans or MediSave funds. Switzerland: basic premiums cannot exceed 8 % of personal income; subsidies cover the excess for low‑income earners. United States: private insurance dominates (≈ 69 % of adults); public programs include Medicare (seniors/disabled) and Medicaid (low‑income families/children). Out‑of‑Pocket Maximum ends the insured’s cost‑sharing; any further covered services are paid in full by the insurer. --- 🔄 Key Processes Receiving Care Check if the provider is in‑network → lower rates. Verify prior authorization if required. Cost‑Sharing Flow Apply deductible (if not yet met). Apply coinsurance on the remaining amount. Add any copayment for the specific service. Tally the payment toward the out‑of‑pocket maximum. Risk‑Adjustment in the Netherlands Each insurer receives a per‑person payment from the equalisation pool. Payments are larger for high‑risk enrollees, ensuring no adverse‑selection loss. Supplemental Insurance Decision (Netherlands, Singapore, Switzerland) Identify services not covered by the basic plan. Compare supplemental premium vs. expected out‑of‑pocket cost for those services. --- 🔍 Key Comparisons Public vs. Private Funding Public: taxes/mandatory premiums, universal access (e.g., NHS, Dutch basic). Private: individual/employer premiums, may include cost‑sharing (deductibles, copays). In‑Network vs. Out‑of‑Network In‑Network: discounted rates, lower patient cost‑sharing. Out‑of‑Network: full provider charges plus any patient cost‑sharing. Deductible vs. Copayment vs. Coinsurance Deductible: fixed dollar amount paid first. Copayment: fixed dollar amount per service after deductible. Coinsurance: fixed percentage of the bill after deductible. Basic Mandatory vs. Supplemental Insurance (Netherlands, Singapore, Switzerland) Basic: required by law, uniform premium, limited benefits. Supplemental: optional, higher premiums, broader or higher‑level coverage. US Medicare vs. Medicaid vs. Private Plans Medicare: federal program for seniors/disabled; pays many services but often includes cost‑sharing. Medicaid: joint federal‑state program for low‑income individuals; covers a broader set of services with minimal cost‑sharing. Private: employer‑sponsored or marketplace; premiums and cost‑sharing vary by plan tier. --- ⚠️ Common Misunderstandings Deductible includes copays – the deductible is separate; copays are charged in addition to any deductible still owed. All premiums vary by health status – in the Netherlands and Swiss basic plans, premiums are the same for everyone in the same age/region bracket. Out‑of‑network care is always covered – many plans either deny coverage or apply higher cost‑sharing; the patient may pay the full amount. Medicare covers all medical expenses – it still requires deductibles, copays, and coinsurance, and does not cover everything (e.g., most dental, vision). Universal coverage means no cost‑sharing – even universal systems (e.g., Singapore’s MediShield Life) employ deductibles, coinsurance, and copayments to encourage personal responsibility. --- 🧠 Mental Models / Intuition “Bucket” model: The insurer’s risk pool is a bucket of many people’s contributions (premiums). The insurer draws money from the bucket to pay individual “holes” (medical bills) after each person’s personal “layer” (deductible, copay, coinsurance) is filled. Network as a “fast lane”: In‑network providers are the fast lane with lower tolls (cost‑sharing). Out‑of‑network is the slow lane where you pay the full toll. Risk‑adjustment as a “scale”: The equalisation pool adds weight (funds) to insurers with heavier loads (high‑risk members) to keep the scale balanced. --- 🚩 Exceptions & Edge Cases Netherlands basic insurance: No copays, caps, or deductibles allowed; premiums are identical regardless of health. Singapore MediShield Life: No coverage for overseas treatment, pre‑existing conditions within 12 months, congenital anomalies, cosmetic surgery, pregnancy, or mental illness. Switzerland: Basic‑plan premiums cannot exceed 8 % of personal income; excess is subsidised. US ACA‑non‑compliant plans: Carry higher risk than federal estimates and may lack essential health benefits. Capitation contracts: Fixed provider payment irrespective of actual service volume; may incentivize efficiency but risk under‑service. --- 📍 When to Use Which Choose In‑Network whenever possible to minimise out‑of‑pocket costs. Select a high‑deductible, low‑premium plan if you expect low annual utilization and have a Health Savings Account (HSA) to cover the deductible. Add supplemental coverage in the Netherlands, Singapore, or Switzerland if you anticipate needing services excluded from the basic package (e.g., dental, private‑ward hospital stays). Use Medicare for seniors/disabled; supplement with Medigap or Medicare Advantage for broader coverage. Consider Medicaid if income is below eligibility thresholds and you need comprehensive coverage with minimal cost‑sharing. --- 👀 Patterns to Recognize Cost‑sharing sequence: Questions that mention a deductible, then a percentage, then a fixed dollar amount → apply deductible → then coinsurance → then copay. Risk‑adjustment language (equalisation pool, risk‑adjusted funding) → points to the Netherlands system. “Mandatory basic” + “same premium for all” → Dutch or Swiss basic insurance. “Out‑of‑Pocket Maximum reached” → insurer pays 100 % of any further covered services. “Prior authorization required” → expect a delay before service and guaranteed payment once approved. --- 🗂️ Exam Traps Trap: Assuming a deductible covers copays → remember they are separate layers. Trap: Selecting “premium varies with health status” for Dutch basic insurance → premiums are uniform. Trap: Believing Medicare eliminates all patient cost‑sharing → deductibles, coinsurance, and copays still apply. Trap: Choosing “out‑of‑network care is fully covered” → many plans limit or deny coverage; patient may owe full bill. Trap: Interpreting “formulary” as the EOB – the formulary lists covered drugs; the EOB explains what was actually paid for a claim. ---
