1 Pricing Variations in the Consumer Market for Diagnostic Imaging Services / Prepared by: Reginald D. Williams II, Amy Rousseau, and Jon Glaudemans, For: CareCore National December 2005

2 Prices for healthcare services are frequently a mystery to even the most informed consumers. Increasingly, as insurance companies and HMOs continue their move away from fixed dollar co-payments to percentage co-payments, consumers and patients first glimpse into the cost of a service comes when they receive a bill in the mail from the healthcare provider or the insurance company. As more and more patients seek ways to shop for expensive healthcare services, they face a set of frustrating and bewildering barriers to obtaining accurate projections of their expected out-of-pocket expenses for a given service. Some of these are personal: many people are uncomfortable asking their physician or local hospital for a price list. Other barriers are more institutional: many insurance companies and physicians either refuse or are reluctant to disclose the prices for individual services. A recent analysis of prices among competing providers of high-cost diagnostic imaging services reveals significant variation among these providers, and suggests that consumers are likely to experience widespread differences in out-of-pocket costs, depending entirely on where they obtain the imaging service. Is the healthcare marketplace prepared to offer consumers the pricing information to make meaningful choices? In particular, can a wouldbe patient today effectively shop for high-cost medical services such as magnetic resonance imaging (MRI) and computerized tomography (CT) scans the way they would for another high-cost purchase? There is broad consensus that would-be purchasers of high-cost healthcare services, including diagnostic imaging, would be stymied today in their search for accessible, easy-to-understand measures of quality, performance, and overall value. Despite new price transparency efforts that have been launched by various managed care organizations, information on the actual cost of healthcare services is not widely available to most consumers. The absence of data is particularly troubling for individuals facing significant out-ofpocket expenses for healthcare, either because they have an insurance plan that imposes percentage co-payment requirements, or, increasingly, because they are enrolled in a so-called consumer-directed health plan, where the consumer faces significant first-dollar exposure for most healthcare services. Consumer-Directed Health Plans on the Rise Consumer-directed health plans (CDHPs) are based on the premise that consumers will actively seek out and use information on quality and cost to make better healthcare decisions if they face direct and personal financial consequences for their decisions. For members of CDHPs this level of financial responsibility is significant. Consumers enrolled in CDHPs typically buy into high-deductible health insurance products, coupled with individual accounts for health expenses. These accounts are similar to 401Ks. 1

3 How real is the rise of CDHPs? The passage of the Medicare Prescription Drug Improvement and Modernization Act of 2003 increased the momentum of the CDHP movement by introducing tax-advantaged Health Savings Accounts (HSAs). A 2005 survey estimated that the number of employers offering high-deductible CDHPs has increased from 5% in 2003 to 20% in Within the past year, the number of enrollees in CDHPs has doubled. According to America s Health Insurance Plans, in September 2004, only 438,000 consumers were in CDHPs. As of March 2005, over one (1) million people were enrolled in these plans. 2 With no easing of rising healthcare costs in sight, and more consumers seeking to assert increased control over their own healthcare, industry analysts have projected that CDHPs will cover 22 million lives in the commercially insured market by In 2005, deductibles averaged $1,901 for single-person coverage and $4,070 for family coverage in high-deductible health plans with an individual account. The maximum out-of-pocket liability for cost sharing averaged $2,551 for single-person and $4,661 for family coverage. In CDHPs, that couple high-deductible insurance coverage with HSAs, healthy individuals needing expensive services, such as diagnostic imaging, are likely to incur the entire cost of those services before reaching their maximum liability. For example, a healthy jogger who needs one MRI for an injured knee could be exposed to an out-of-pocket cost of over a thousand dollars, depending on the choice of providers. Against this possibility, what tools do consumers need to make informed decisions? Regardless of whether the patient is in a CDHP, or, alternatively, in a percentage co-pay traditional plan, patients need help to navigate the healthcare system s invisible pricing system. CDHPs Meet Diagnostic Imaging / The Challenges of Shopping for High-Cost Medical Services Diagnostic imaging modalities, such as MRI and CT, are widely available in the United States. As these technologies improve and more indications are found for their use, diagnostic imaging will play an increasingly important role in improving people s health. The rise in utilization of noninvasive diagnostic imaging procedures has proved to be a leading cost driver in overall U.S. healthcare expenditures. The Blue Cross and Blue Shield Association estimated that about $70 billion was spent on diagnostic imaging in In Medicare alone, spending for imaging 1 Kaiser Family Foundation (KFF) and Health Research and Educational Trust (HRET).

4 services grew from $5.7 billion in 1999 to $9.3 billion in 2003 an increase of over 60 percent, and one of the fastest-growing portions of the Medicare budget. 5 The majority of patients who require diagnostic imaging services are currently shielded from the full costs associated with them because they are enrolled in either traditional managed care or indemnity plans. These plans limit patient liability to a modest deductible and percentage copayment arrangements, where the patient is required to pay 20-50% of the insurance companies negotiated rates. Traditional theories of insurance suggest that such patients have little incentive to seek out cost-effective imaging providers. Under both percentage co-payment plans and under CDHP plans, patients referred for high-cost diagnostic imaging have a strong incentive to exercise prudent purchasing. However, to date, they have typically lacked the information on cost to help them make an informed decision. Consumers need accurate tools to access this information, and educational support to evaluate it. What Would You Do? A Glance at Diagnostic Imaging in New Jersey A new analysis conducted by Avalere Health, using data provided by one of the nation s leading diagnostic imaging management companies, examines the dilemma facing an average patient in New Jersey shopping for a provider of diagnostic imaging services. This detailed analysis reviews the cost of imaging services performed at a variety of imaging facilities under contract to two large managed care plans in These facilities offer a range of services including those that involve two of the most costly and commonly used imaging modalities CT and MRI. Table 1 shows the top five imaging procedures (identified by CPT 5 Code) in New Jersey for each of these two modalities CT and MRI and arrays the charge data (what the facilities would typically charge a walk-in patient without access to insurance or insurance company-negotiated rates). Throughout the paper, dollar amounts represent the sum of the technical (cost of the machine) and professional (cost of the physician) components of an imaging service. As Table 1 shows, a walk-in patient s out-of-pocket exposure can vary by as much as 950%. Clearly, with these substantial differentials among the imaging providers charges, information on prices would be useful data for the consumer. 6 Miller, Mark.

Patients willingness to travel long distances for care especially care that is relatively routine is limited. Thus, our analysis further examined the market from the patient s perspective, and focused on facilities in each of two separate counties, X and Y. We use counties as a proxy for patients local communities. Table 2 presents the mean price variation in provider charges for the top 5 CT and MRI procedures, in each of these two counties, and displayed in two groups: highand low-cost facilities, with the figures again, rounded to the nearest $50 increment. The figures in Table 2 are charge levels and typically represent the retail price faced by the self-insured or uninsured patient. The higher-cost facilities tend to be hospitals (designated by an H preceding their identifying number) and the lower-cost facilities tend to be free-standing imaging centers (designated by FS preceding their identifying number). Even within a county, there exist significant charge disparities among providers. Again, a consumer facing significant out-of-pocket exposure under a high-copayment plan or a CDHP would experience major variations in cost, even when limiting her search to providers within a relatively tight geographic market. 4

7 All insurance plans and most CDHPs offer their enrollees access to negotiated rates that are often well below facilities charges. Recognizing that many consumers have access to the plan s negotiated rates, Table 3 arrays the median negotiated rates, rounded to the nearest $100 increment. Again, the variation is striking and differences between providers in excess of 300% are not uncommon. Table 3.

8 In both cases charges and negotiated rates there are significant variations between facilities, suggesting that negotiation may reduce the absolute level of payment but not the variance in payment rates. Consumers are, on average, better off using negotiated rates. But significant disparities among providers offer little comfort to the uninformed consumer seeking best value for their healthcare dollar. Finally, to address the legitimate possibility that facilities with different prices may offer different levels of quality, the analysis compared groups of high-cost and low-cost facilities that happen to use the same radiologists to oversee and interpret the images. For each county, we created facility pairs, where the only difference between the two facilities was site of service. For each, given pair, the same radiology group performs the test and interprets the image. This analysis eliminated a major possible source for pricing discrepancies: variation in the quality of the physician. Table 4 displays these paired facilities. Table 4. Variation in Charges Between Pairs of Facilities Using the Same Group of Radiologists Radiologists in X County High Cost Facility Low Cost Facility Percent Group A CPT 5 # Charges # Charges Difference CT-Head H1 $1,800 FS2&3 $ % CT-Chest H1 $2,150 FS2&3 $ % CT-Pelvis H1 $2,150 FS2&3 $ % Group B CT-Sinuses H3 $800 FS1 $700 14% CT-Chest a H3 $900 FS1 $700 29% MRI-Upper Extremity Joint H3 $1,300 FS1 $1,000 30% Radiologists in Y County Group C CT-Head H5 $1,550 FS4 $ % CT-Chest H5 $1,950 FS4 $ % CT-Pelvis H5 $2,300 FS4 $ % Group D MRI-Brain a H4 $3,100 FS5 $1,650 88% MRI-Back H4 $2,050 FS5 $1,100 86% MRI-Lower Extremity Joint H4 $2,150 FS5 $1,100 95% Based on a sample of charge data from two health plans in X and Y counties in New Jersey; data rounded to nearest $50 to avoid revealing competitively useful information. a With contrast, a substance used to enhance the quality of diagnostic imaging SOURCE: CareCore National 7

9 Again, the price variations are striking. Even when the same radiologist oversees a head CT scan for a patient in X County, the out-of-pocket exposure for a walk-in patient visiting Hospital 1 (H1) is nearly 140% more than a similar patient s exposure visiting either free-standing Facility 2 or 3 (FS2&3). Recall that such variation exists with negotiated rates as well, even if negotiated rates tend to be lower than charges. These results demonstrate how confusing it can be for patients to evaluate cost and quality differentials for similar services. Yet, as more patients face higher co-payment levels, and as CDHP enrollment rises, healthcare consumers will surely demand better information and tools to assist them in making important healthcare decisions. 8

10 What s Next? Employers, insurers, and the imaging industry can work together to help consumers make empowered, data-based decisions in the marketplace. There is a real opportunity to develop valuable tools that assist consumers and patients in choosing the appropriate providers of care. Absent clear and accurate information on quality differences between providers, a useful first step may to provide patients and consumers with accurate cost information. Insurance plans and providers that choose to offer cost data to enrollees who need diagnostic imaging procedures will help their members and patients make better decisions by increasing their ability to select costeffective, high-quality providers. Providing enrollees with selected cost information will not guarantee a more efficient market for diagnostic imaging procedures. A more comprehensive approach would combine three essential services for a patient: an independent assessment of the appropriateness of the recommended imaging procedure; assurance that the recommended or chosen facility meets a rigorous set of quality and service metrics; and timely and accurate information on the out-of-pocket prices across competing facilities. 9
