Insurance's Impact: Driving Up Healthcare Costs

how does insurance drive up healthcare

The cost of healthcare is a pressing issue, with the US spending around $3.5 trillion on health-related services in 2017. Insurance companies are key players in the US healthcare system, and their influence on affordable care is a topic of increasing interest. While insurance is important to the millions of Americans who receive coverage through their jobs, the way some commercial insurance companies operate creates significant overhead for hospitals and dangerous care delays for patients. This is due to a variety of factors, including inappropriate use of prior authorization, stringent utilization reviews, and demanding high deductibles and copays. These factors contribute to rising healthcare costs and impact patient access to care.

Prior authorization and step therapy add unnecessary administrative costs and cause treatment delays

Prior authorization (PA) and step therapy are practices used by insurance companies to control costs and ensure appropriate use of medications. PA is the process by which physicians must obtain advance approval for a device, supply, or medication from the patient's insurance plan to ensure coverage for the recommended service. This time-consuming process burdens family physicians and their staff, diverting resources away from patient care and leading to adverse health outcomes. The American Academy of Family Physicians (AAFP) believes that the growing number of PAs should be scrutinized for their impact on patient care and that PAs should be standardized and converted to more efficient electronic processes to promote conformity, improve timeliness, and reduce administrative burdens.

Step therapy, also known as "fail-first" therapy, is a type of PA that requires patients to try lower-cost or insurer-preferred medications before progressing to more expensive or brand-name drugs. While insurers promote step therapy as a way to control prescription drug costs and find the most appropriate treatments for patients, critics argue that it can cause unnecessary delays in treatment and allow medical conditions to worsen. For example, a patient with severe eczema became suicidal when their insurer wouldn't approve a new treatment, and a seventh-grader with juvenile rheumatoid arthritis was denied a drug that could have slowed the disease's progression.

The AAFP joins other medical organizations in supporting policies that reduce the negative impact of PA and step therapy. They argue that these protocols can create significant barriers to delivering timely and evidence-based patient care, lower adherence to recommended treatments, and lead to adverse health consequences. Decisions in response to PA and step therapy requests should be made in a timely manner, with denials including clinical rationale and allowing physicians to provide supporting documentation.

The proposed Safe Step Act, with bipartisan support, aims to create more transparency about step therapy rules and cover more patients, including those with employer-based health insurance plans. Additionally, new laws targeting step therapy aim to address concerns about treatment delays and the interruption of successful treatment plans. These laws would speed up the exception process for patients who have already tried and failed on a required drug or if delays could lead to severe or irreversible consequences.

Insurers' market power concentration allows hospitals to demand higher prices

The US health insurance industry is highly concentrated, with a few large, nationwide insurers dominating the market. This concentration has been driven by consolidation, mergers, and acquisitions among existing insurance companies, as well as the exit of some insurers from the market. As a result, markets have become less competitive, leading to higher premiums and decreased access to affordable health insurance for consumers.

In a market with a high concentration of insurers, hospitals' ability to exercise their market power and raise prices is reduced. This is because insurers have stronger bargaining power and can negotiate lower payment rates with hospitals. However, when there are only a few dominant insurance companies, hospitals can use their strong bargaining position to command higher prices. This is especially true if the hospital is the dominant player in the market, as insurers must include it in their plans to remain competitive.

Research has found that in markets with a median level of insurer concentration, a hospital with high concentration can charge significantly more per procedure than a hospital in a market with lower concentration. The difference in prices between hospitals in the 75th and 25th percentiles of concentration is much smaller when the concentration of insurers is high. This suggests that insurer market power plays a crucial role in hospital pricing.

The impact of insurer concentration on hospital pricing is complex and depends on various factors, including the level of competition in the local market and the bargaining power of both insurers and hospitals. While insurer market power can lead to higher premiums, it may also enable them to negotiate lower provider prices and partially offset these increases. Overall, the concentration of power among insurers and hospitals can have significant effects on healthcare costs, and it is important to consider both supply- and demand-side characteristics of the market to understand the full impact.

Insurers' stringent utilization reviews and excessive claims denial processes limit healthcare usage and payment

The cost of healthcare in the United States is significantly higher than in other developed countries, and insurance companies play a major role in driving up these costs. Private health insurance is the most common source of health coverage in the US, with 91.4% of Americans insured in 2022, compared to 99-100% in other industrialised countries.

Insurers employ various strategies to limit healthcare usage and payment, including stringent utilisation reviews and excessive claims denial processes. For instance, insurers often require prior authorisation, where providers must obtain approval from the insurer before delivering a treatment. While this is intended to ensure patients receive appropriate care covered by their plan, insurers often overuse prior authorisation, delaying treatment and increasing administrative costs for healthcare providers.

Insurers also enforce narrow provider networks, high deductibles and copays, and issue denials for essential services, creating barriers to timely and affordable care. They frequently cite "medical necessity" to decline treatment, often based on flawed or stringent policies that are not shared with doctors. This results in additional costs and delays for patients and providers, as they must navigate complex appeals processes.

The lack of transparency around denial rates further exacerbates the issue. Insurers closely guard this information, making it difficult for consumers to know their likelihood of being denied coverage. Despite regulators having the power to address this, they have largely failed to do so, leaving consumers in the dark.

The impact of these practices is significant. They not only hinder patients' access to timely and necessary care but also increase costs for the healthcare system as a whole. Streamlining processes, improving transparency, and holding insurers accountable for wrongful denials are crucial steps towards addressing these issues and making healthcare more accessible and affordable for Americans.

Insurers' employer-sponsored plans and expensive group plans leave employees in a financial bind

Employer-sponsored health insurance, or group health insurance, is a common way for people to receive health coverage, with over 54% of insured Americans enrolled in such plans. Typically, employers pay over half of the premiums, and may also contribute to health savings accounts for employees. However, the cost of healthcare in the US is rising, and employer-sponsored plans and group plans can leave employees in a financial bind.

Firstly, the number of private health insurance companies in each state has decreased over the last decade, leading to market concentration. This concentration can result in higher premiums, decreased access to affordable health insurance, and fewer options for consumers. In concentrated markets, three or fewer insurance companies hold at least 80% of the market share of enrollment. This can make it difficult for new insurers to enter the market and foster less competitive practices.

Secondly, the way some commercial insurance companies operate creates significant administrative costs for hospitals and delays in patient care. For example, the overuse of prior authorization and step therapy adds unnecessary costs in terms of staff time, technology, and software. Prior authorization is intended to ensure patients receive the right care and that it is covered by their plan. However, the process is often manual and time-consuming, delaying treatment. Step therapy, or "fail first" policies, require patients to try the insurer's recommended treatment first, which may not be what their doctor initially prescribes. This can result in adverse health outcomes and increased costs of subsequent care.

Thirdly, commercial insurers often decline to approve or pay for treatments, citing "medical necessity" based on flawed or stringent policies that are not always shared with doctors and hospitals. This interferes with patient care and adds costs to the system, especially if patients and providers must then undergo an arduous appeals process.

Finally, employer-sponsored plans often require higher estimated contributions from those covered compared to marketplace plans. For example, deductible spending may require enrollees to finance high expenses all at once. Those with hospitalizations or chronic conditions often incur higher cost-sharing over the year. For instance, individuals with a diabetes diagnosis incurred costs of $1,585 in 2017. Large group enrollees faced an average of $779 in cost-sharing, but this can vary depending on health services used.

Insurers' narrow provider networks restrict patient choice and impose financial burdens

The American healthcare system is facing challenges due to the increasing concentration of the private health insurance market in the hands of a few large companies. This trend has resulted in higher premiums, reduced access to affordable health insurance, and limited options for consumers. The issue is further exacerbated by the decline in the number of private health insurance companies in each state, with a few dominant firms insuring most private policyholders.

Narrow provider networks, offered by many health plans, restrict patient choice and impose financial burdens. These networks limit patients' access to their preferred doctors or hospitals, and they can also lead to excessive appointment wait times. In some cases, patients are denied coverage for specific procedures or treatments due to religious or secular restrictions imposed by the insurance company. For instance, a woman was denied a tubal ligation due to Catholic hospital policy when her insurance provided no alternative options.

The use of prior authorization and step therapy by commercial insurance companies adds unnecessary administrative costs and delays in patient care. Prior authorization requires providers to obtain approval from insurers before delivering a treatment, and its overuse can hinder timely care. Step therapy mandates that patients first try the insurer's recommended drug treatment, which may contradict the doctor's clinical expertise. These practices can interfere with the doctor-patient relationship and, in some cases, cause irreversible harm to patients.

To address these concerns, the American Medical Association (AMA) has advocated for "any willing provider" legislation, aiming to enable physicians to establish successful practices and deliver quality care without restrictions imposed by insurance companies. The AMA also emphasizes the need for regulatory oversight, including meaningful standards, transparency, and effective monitoring to ensure network adequacy and reduce the burden on physicians and patients.
