  • 1. NUR 751:Healthcare Economicsfor the DNPThe Market forHealth InsuranceDewar, D. (2010). Essentials of health economics. Sudbury, MA:Jones & Bartlett Learning Co.Tony Umadhay, PhD., CRNABarry University
  • 2. The Insurance Market• People buy insurance because they are risk-averse– Buying insurance allows a person to pay a certainknown amount in order to transfer the risk of a muchlarger expenditure (in the case of an adverse event)to an insurer, known as a third party payer• There are a number of types of risk associated withhealth– Risk to one’s health and life associated with illness ordisease– Risk that if one undertakes treatment, it may or maynot cure or alleviate symptoms of disease– The costs associated with the treatments of illnessand disease
  • 3. The Insurance Market• People can insure themselves against some or allof the financial loss associated with the treatmentof illness by buying health insurance policies– Even people with extensive wealth buyinsurance due to the fact that most people are“risk-averse”• Economists define risk aversion as a characteristic ofpeople’s utility functions:– People are more likely to buy insurance for low probabilityevents involving large losses than high probability eventsassociated with small losses.– Lottery (low probability of winning a large amount)• That is a situation of risk aversion
  • 4. Setting Insurance Premiums• The price that an insurance company chargesfor an insurance policy, or premium, is based onthe expected payout (amount paid out onaverage for a large group of insured persons),plus administrative costs, reserve funds, andprofits or surpluses of the insured company– Premiums charged generally exceed the fairvalue of the risk that the insurance companyhas assumed, where the fair value is theexpected payout
  • 5. Setting Insurance Premiums• The part of the insurance premium that exceedsthe fair value of the insurance is called the“loading fee”• Suppliers of insurance will be more willing toenter market situations where they can make areasonable estimate of what their payouts willbe, or where they can assess the degree of riskthey are assuming
  • 6. Experience versus CommunityRating• One common method of pricing insurance isexperience rating– Insurance companies base premiums on pastlevels of payouts, which is often done in thecase of car or homeowners’ insurance.• Community rating applies when each memberof an insurance pool pays the same premiumper person or per family for the same coverage– Community rating is inefficient in the sensethat the price of insurance to an individualsubscriber does not reflect the marginal costsof that individual to the insurer.
  • 7. Moral Hazard• Moral hazard refers to the phenomenon of aperson’s behavior being affected by his or herinsurance coverage– Moral hazard is known to exist is in all typesof insurance markets• People may be more careless with propertythat is insured• The main way that moral hazard comesinto play in the health insurance market isthrough an increase in demand forhealthcare services utilized
  • 8. Moral Hazard and the Structure ofHealth Insurance Contracts• The reason that moral hazard operatesdifferently in the health insurance market than inother insurance markets is that health insurancecontracts differ from most other forms ofinsurance– Instead of paying a sum of money to theinsured in the case of an adverse event, theyreduce the price of the health care associatedwith the adverse event or illness
  • 9. Moral Hazard and the Structure ofHealth Insurance Contracts• Major healthcare services contracts also differfrom most types of insurance in that theygenerally cover more than just unlikelycatastrophic events, also fulfilling a functionanalogous to that of a service contract on anautomobile– they also include reimbursement for annualphysical exams, vaccinations, treatment forchronic conditions, and various types ofroutine tests
  • 10. Cost Sharing to Offset Effects ofMoral Hazard• Deductibles. A deductible is a level expenditurethat must be incurred before any benefits arepaid out– Health insurance policies generally haveyearly deductibles, which is less effective inremoving moral hazard• Coinsurance. Coinsurance is the proportion ofthe total expenditure that is paid by the insured– Coinsurance helps to reduce the moralhazard factor for the insured that have spentmore than their deductible because healthcare is not free to them
  • 11. Cost Sharing to Offset Effects ofMoral Hazard• Use of Usual, Customary Fees to Limit Payments. Ithas become common practice for insurance policiesthat reimburse on the basis of fee-for-service to limitpayment for covered services to customary or usualfee within given geographic markets• Managed Care. Care is actually managed orrationed using such mechanisms as “gatekeepers,”who are primary care physicians that make allreferrals to specialists, limit coverage to serviceproviders with whom the insurance company has acontractual agreement, and require precertificationor approval from the insurance company beforeservices are rendered
  • 12. Cost Sharing to Offset Effects ofMoral Hazard–Controls are on the supply side as wellas the use of risk-sharing arrangementswith providers of health care• Stop-Loss Provisions. Many policies alsohave annual limits on out-of-pocketexpenditures (per person or per family)that must be borne by the insured
  • 13. Adverse Selection• Adverse selection exists when people with differenthealth-related characteristics than the average personincrease the amount of health insurance purchased– People know more about their own health status thaninsurers, and this inequality of information is the basis forrisk to insurers• In the health insurance market, high risk people are thosewith more severe health problems than the average person– These people would be overrepresented in theinsurance markets, particularly those markets with moreinclusive policies• This would drive up the premium because the highrisk persons would use more health care and drive offthose with better health from buying the insurancepolicies
  • 14. Insurers’ Responses to SelectionProblems• Insurers engage in positive selection, where thecompanies structure coverage to both avoidadverse selection and also to attract lower-than-average risk subscribers• The disappearance of insurance options due tothe spiraling costs associated with adverseselection has been a serious problem in themarket for individual direct pay policies inregions that require community rating
  • 15. Offsetting Adverse Selection• Some economists have questionedwhether health insurance markets canreach equilibrium, given the role ofadverse selection• Consumers no longer have much of theinformation advantage in choosing thebest package of insurance to cover theirfuture expenditures
  • 16. Employer-Based Insurance• Advantages of employer-based insurance– Group insurance is important for offsettingadverse selection• Community rating applies within theemployment group, which results in somedegree of risk sharing• Economies of scale in administrative ratesare lower than those for individual or directpay policies– Insurance companies may still use experiencerating to charge higher prices to higher-riskgroups .
  • 17. Employer-Based Insurance• Disadvantages of Employer-Based Insurance– When health insurance is tied to employment,job loss involves the risk of losing access toaffordable health insurance– The Consolidated Omnibus BudgetReconciliation Act of 1985 (COBRA) requiresemployers to offer former employees anoption of purchasing their former group healthinsurance coverage for up to 18 months aftertermination of employment• This provides only a temporary solution andmay be unaffordable because theemployee must pay the entire premiumplus a two percent fee
  • 18. Employer-Based Insurance– Tying of health insurance to employmentreduces labor mobility and results in what isconsidered to be job lock. Researchconcludes that employer-provided insurancehas reduced labor mobility by about 25 to 30percent• Health Insurance Portability andAccountability Act (HIPAA) of 1996addresses part of the problem by making itillegal for insurers to exclude any employeefrom a group plan on the basis of health-related factors or past claims history
  • 19. Tax Treatment of Employer-Based Health Insurance• Under federal and state income tax law, health insurancepremiums paid by employers as part of the workers’compensation package have been tax-free income toemployees and tax-deductible labor costs for firms since1954– This has led to worker preferences for higherproportions of their compensation packages in theform of health insurance, because firms can offerworkers’ compensation that represents more after-taxbenefits that a cash wage package costing the firm anequal amount
  • 20. Optimal Insurance Contracts• Constructing an optimal insurance policy is challengingwhen considering the issue of adverse selection– Where there is a menu of health insurance plansavailable, the less healthy people will be attracted to themore generous plans• Optimal insurance also needs to consider the degree ofrisk sharing between healthcare providers and insurers– Optimality requires a balance such that the providersneither provide more than medically appropriate norwithhold care– One problem in modeling the optimal insurance contractis that the degree of moral hazard may vary by type ofillness or type of healthcare service
  • 21. Reimbursement• The method of reimbursement relates to the wayin which healthcare providers are paid for theservices they provide• Retrospective Reimbursement– Retrospective reimbursement at full costmeans that hospitals receive payment in fullfor all healthcare expenditures incurred insome prespecified period of time.Reimbursement is retrospective in the sensethat not only are hospitals paid after they haveprovided treatment, but also in that the size ofthe payment is determined after treatment isprovided•
  • 22. Reimbursement• Prospective Payment– Prospective payment implies that payments areagreed upon in advance and are not directly related tothe actual costs incurred– With global budgeting, the size of the budget paid tothe hospital is set prospectively across the wholerange of treatments provided• This provides a financial incentive to constrain totalexpenditure– With prospectively set costs per case, the amountpaid per case is determined before treatment isprovided
  • 23. Integration Between Third PartyPayers and Healthcare Providers• There are three different kinds of integration between thirdparty payers and healthcare providers– First, the third party payer and provider are separateentities with separate aims and objectives– Second, there is selective contracting, with the third-party payer agreeing to steer individuals insured on theirplans to selected providers, and, in turn, the selectedproviders charge lower prices to the insurers– Third, there is vertical integration in which theinsurance provider and healthcare provider merge tobecome different parts of the same organization
  • 24. Managed Care• Managed care organizations (MCOs) have arisenpredominantly in the private health insurance sector in theUnited States as a means to control spiraling healthcarecosts arising from the traditional private health insurancemodel (sometimes called the indemnity plan)– Health care is provided by an MCO to a definedpopulation at a fixed rate per month– Payments made by individuals are lower than the directout-of-pocket payment or indemnity plans• In return for lower premiums, enrollees are requiredto receive health care from a limited number ofproviders with whom the MCO has negotiated lowerreimbursement rates– There are three broad types of MCOs, reflectingthe extent of integration between third-partypayers and healthcare providers
  • 25. Preferred Provider Organizations• In return for payment of the insurance premium,preferred provider organizations (PPOs) provide insuredindividuals with two options when they require treatment– They can use the PPO’s providers—those with whichit contracts selectively in return for lowerreimbursement rates• By using a preferred provider, individuals facelower user charges, and so the reduced costs ofcare with the preferred provider are passed on tothe consumer• Alternatively, individuals may choose to use a differentprovider outside of the network of preferred providers,but will incur higher user charges– Patients can choose freely because there are nogatekeepers restricting the choices, however there isa clear financial incentive to stay within the network ofpreferred providers
  • 26. Health Maintenance Organizations• In its simplest form the main feature of a healthmaintenance organization (HMO) is that theinsurance company and the healthcare providervertically integrate to become different parts ofthe same organization– The HMO provides health care to theindividual in return for a fixed fee, thereforecombining the role of the third party payer andthe healthcare provider
  • 27. Health Maintenance Organizations• There are four broad types of HMOs, reflectingdifferent relationships between the third partypayer and the healthcare provider– In the staff model, the HMO employsphysicians directly– In the group model, the HMO contracts with agroup practice of physicians for the provisionof care– In the network model, the HMO contracts witha network of group practices– In the case of independent practiceassociations, physicians in small independentpractices contract to service HMO members.
  • 28. Point-of-Service Plans• Point-of-Service (POS) plans are a mixture of PPOsand HMOs– As with the PPOs, in return for payment of aninsurance premium, patients have two optionswhen they require treatment:• use the preferred provider network and paylower charges• use the non-networked providers on lessfavorable financial terms– Unlike PPOs, however, POS plans employprimary care physician gatekeepers whoauthorize any health care provided by thepreferred provider network• In this way, POS plans are like HMOs
  • 29. Options for Healthcare Financing• Private Health Insurance– Individuals enter into contracts with insuranceproviders voluntarily and pay premiums out-of-pocketor are paid by their employers as part of their salarypackage or both. Private health insurance isusually supplied by providers for profit, though itcan also be offered by public bodies or by nonprofitorganizations– The size of the insurance premium is usually basedon the risk status of the insured individual– Patients may be required to pay user charges, in theform of copayments or deductibles to cover all or partof the costs of their health care
  • 30. Options for Healthcare Financing• Social Insurance– Workers, employers, and government all contribute tothe financing of health care by paying into a socialinsurance fund– Payments by employees can be fixed, or related tothe size of their income, but not to their individual risk– Membership in social insurance funds may beassigned according to occupation or region ofresidence, or individuals may be free to choose a fund– Contributions can be made into social insurancefunds for retired and unemployed individuals either bythe state, or via pension funds and unemploymentfunds.
  • 31. Health Insurance and theConsumption of Healthcare• Insurance Coverage and Time Costs– When insurance coverage lowers the monetary costs ofhealthcare services to people, the time cost becomes amore important component of total cost• This will tend to increase the time-price elasticity ofdemand for health care, with the result being thatconsumers may shift to using healthcare servicesthat have higher monetary costs, but less time costs(e.g., waiting time or travel time)• Insurance Coverage and the Market Price of HealthCare– More extensive insurance coverage on the part of acommunity will tend to increase the quantity of healthcare that will be consumed at a given market price• This implies that there will be a shift in demand.
  • 32. Insurance Trends• Over the past twenty years there has been a noticeabledecrease in the amount that employers are willing to payfor insurance premiums– Firms increasingly offer only base-level insuranceplans and give employees the option of paying thedifferences for more extensive coverage if they sochoose• Health insurance coverage has declined in large partbecause workers have not exercised options to purchaseit– The rise in insurance premiums and the cutback inthe proportion of the premiums that the employers arewilling to pay have left many workers withoutaffordable premium costs
  • 33. Summary• The demand for health insurance exists because of theuncertainty associated with a person’s state of healthand the risk of very large expenditures in the case ofillness– Health insurance provides risk sharing between theinsured and insurer, pooling risks among the insured,and sometimes risk sharing between the insurer andhealthcare providers• Insurance increases the demand for health care, as wellas its price• After decades of discussion, questions still remain aboutthe welfare effects of subsidizing employer-basedinsurance through favorable tax treatment
