Today's High Coinsurance Health Plans: Poor Protection Against Medical Expenses & Will Not Survive Obamacare

38% of health insurance plans do not include their deductible within their Out-of-Pocket limit

“Coinsurance” is a familiar concept for consumers who have purchased health insurance in the individual and family market. As a percentage of medical costs paid out-of-pocket by consumers, coinsurance is often used by a health plan as a method of cost-sharing for more expensive services such as hospitalization, inpatient and outpatient surgeries, child birth, and emergency care. If a plan, for example, had a 15% coinsurance for a particular medical service and that service cost $10,000 then a consumer enrolled in the plan would pay $1,500.

HealthPocket analyzed 9,711 plans that used coinsurance rates to determine the average coinsurance charge across the nation. HealthPocket’s analysis revealed that the average coinsurance rate for existing individual and family health plans was 20%. Three quarters of plans had coinsurance at or below the 20% national average, leaving a quarter of plans with a coinsurance rate above the national average.

Upon closer inspection of the data, HealthPocket also found a surprising relationship between the coinsurance rate required of plan members and the annual limit health plans placed on out-of-pocket costs.

Coinsurance Range Average Annual Out-of-Pocket Limit
Up to 10% $4,286
11% through 20% $5,138
21% through 30% $7,251
31% through 40% $7,518
Above 40% $8,825

HealthPocket found that those plans with the highest average coinsurance expense for consumers also averaged the least financial protection against annual out-of-pocket expenses. For example, plans with coinsurance rates up to 10% capped annual out-of-pocket expenses1 at $4,286 on average with this average rising to $8,825 for plans with coinsurance rates above 40%.

While a direct correlation existed between coinsurance rates and out-of-pocket limits that resulted in a shift of healthcare costs to consumers, a similar relationship did not exist when examining coinsurance rates and deductible amounts.

Coinsurance Range Average Deductible
Up to 10% $3,784
11% through 20% $2,839
21% through 30% $4,349
31% through 40% $3,989
Above 40% $4,432

Plans With Both High Co-Insurance and Annual Out of Pocket Limit Should Be a Concern for Consumers

Plans with coinsurance rates above 40% and a high out of pocket limit were offered by a variety of insurance companies across the U.S. including certain well-known brands. The Health Net’s PPO Advantage 6500 in California is an example of such a plan.

The Health Net PPO Advantage 6500 charges enrollees “50 percent coinsurance for hospital and surgery services after calendar year deductible is met. Most other services covered 100% after annual out-of-pocket maximum is met.”2 Prior to the annual out-of-pocket maximum being satisfied, the enrollee “pays 100% on most services.”3 The out-of-pocket maximum, however, is $9,500 for an individual and $19,000 for a family.4

Given the combination of a high coinsurance rate and a high out-of-pocket limit, consumers considering such a health plan should be financially prepared for high out-of-pocket costs in the event they need extensive medical services during the year. The Affordable Care Act will prevent insurance companies from offering new health plans similar to this Health Net example beginning in 2014.

Changes Coming for Coinsurance and Deductibles Under The Affordable Care Act

The study of coinsurance and deductibles for current plans raises the question of how they will compare to the coinsurance and deductibles of the new health plans created by the Affordable Care Act. The Kaiser Family Foundation commissioned Aon Hewitt to model some potential out-of-pocket cost designs for the upcoming Bronze Plan and Silver Plan.5 The below table compares the average coinsurance rate for current individual and family health insurance to the Aon Hewitt examples of upcoming Bronze and Silver designs.

Plan Coinsurance % Deductible Annual Out-of-Pocket Limit6
Averages for Existing Plans 20% $3,533 $5,595
bronze Bronze Plan – Example 1 20% $4,375 $6,350
bronze Bronze Plan – Example 2 40% $3,475 $6,350
silver Silver Plan – Example 1 20% $2,050 $6,350
silver Silver Plan – Example 2 40% $650 $6,350

When examining the Bronze and Silver plan designs with the same coinsurance rate as the current national average, we find that the Bronze Plan has both a higher deductible and a higher out-of-pocket limit than the averages for existing plans. The Silver Plan, on the other hand, has a significantly lower deductible for the 20% coinsurance plan design, nearly $1,500 less than the average deductible for existing plans. Like the Bronze Plan, though, the Silver Plan’s annual out-of-pocket limit was higher than the current average amount.

The deductible amount decreased as the coinsurance rate was increased within the plan designs provided by Aon Hewitt. For the Bronze and Silver plan designs with a 40% coinsurance, we find the deductibles for both plans beneath the average deductible for existing plans. The Silver Plan with a 40% coinsurance rate had the most significant difference in deductible amounts with its deductible being ⅕ the average seen for existing plans. The Bronze Plan with a 40% coinsurance rate, in contrast, was less than $100 lower than the average seen for existing plans.

For both the Bronze and Silver plans, the increase in coinsurance rate did not accompany a decrease in protections against annual out-of-pocket costs as is the case in the present individual and family health insurance market. The annual out-of-pocket limits remained at the same level as the plan designs with a 20% coinsurance rate. Moreover, the new plans of the Affordable Care Act will always include their deductibles within the annual out-of-pocket limit. A previous study by HealthPocket found that 38% of existing individual and family health insurance plans did not include their deductible within their out-of-pocket limit.7

It is important to note in this discussion of coinsurance rates, deductibles, and out-of-pocket limits that the new Bronze and Silver plans will cover more medical services than the existing plans to which they are being compared. Accordingly, some individuals may find that they will pay a coinsurance charge or copayment where previously they were responsible for the total costs of a previously uncovered medical service such as pediatric dental care. As HealthPocket’s previous research revealed, the average individual and family health insurance plan has only 76% of the benefits that will be included in the new Affordable Care Act plans.8

Concluding Observations on Co-Insurance and Healthcare Transparency

There is nothing inherently wrong a health plan that has an above average coinsurance as long as the consumer evaluates their coinsurance obligation with the other financial aspects of the plan. In fact, exposing consumers to a greater degree of medical expenses through coinsurance has the potential to drive down the costs for American healthcare if it encourages consumers to shop prices comparatively among medical providers and, and this is a big “and,” the market develops widely available mechanisms to access provider prices easily. Without price transparency in the healthcare market, consumerism cannot effectively drive down prices through competition. Currently, we are far from this situation. A 2013 study published by the Journal of the American Medical Association9 found that 40% of hospitals contacted in the study could not provide a complete cost estimate for a hip replacement. The lack of consumer awareness in pricing differences resulted in an enormous difference in potential costs. The least expensive provider charged $11,100 while the most expensive charged more than $125,000.

Of equal importance as transparent pricing information is the matter of medical service quality. Without data indicating the quality of clinical outcomes for various services, consumers could be pushed forward in ‘a race to the bottom’ where medical costs are reduced at the expense of quality of care.


Results of the study were based on an analysis of 9,711 health insurance plans listing coinsurance percentages for beneficiary cost sharing. Flat fee copayments were not analyzed. Health plans were limited to the individuals and family insurance market for consumers under the age of 65. Health plans from the Medicare, Medicaid, and employer-based health insurance markets were not included within this study. The data used in this study was obtained from insurance records made public by the Department of Health & Human Services. The data was collected on March 13, 2013.

All analysis assumes the accuracy of the underlying government data. While every effort was made towards a comprehensive collection of plans, HealthPocket makes no representation that every plan within the individual insurance market or in an individual state was included in this study. Percentages are rounded according to standard industry practices.
