At the risk of economic oversimplification, it is difficult to sustainably provide a service when payment for it is less than the cost to perform it. But that is one reality exposed by Hevesi et al. in the May 15, 2019 issue of The Journal. Using National Inpatient Sample and ACS-NSQIP data, the authors compared the average costs and 30-day complication rates for revision total hip arthroplasties (THAs) performed for 3 different indications—fractures, wear/loosening, and instability—at both a local and national level. They found that the average hospitalization costs associated with a revision THA related to a fracture were 33% to 48% higher (p < 0.001) than the cost of revision THAs related to wear or instability.
However, the authors emphasize that all 3 of these indications for revision THA are reimbursed at the same rate based on Medicare Diagnosis-Related Group (DRG) codes. DRGs take into account patient comorbidities to determine reimbursement levels—but they do not adjust payments for THA revision according to indication. Hevesi et al. note that the only DRG reimbursement level that would cover the average cost of a revision THA for a fracture would be one performed on a patient with severe medical comorbidities or a major complication. Not surprisingly, patients who underwent a revision THA to treat a fracture were found to have a higher age and more medical comorbidities than those undergoing a revision for wear or instability.
The authors use this data to make a very compelling case that DRGs for revision THA should be changed so they are indication-specific, taking into account the underlying reason for the revision. They observe that “a DRG scheme that does not distinguish between indications for revision THA sets the stage for disincentivizing the care of fracture patients and incentivizing referrals to other facilities.” Those “other facilities” usually end up being large tertiary-care centers, which the authors claim “perform a higher percentage of the costlier revision THA indications.”
This problem of reimbursement inequality is not unique to revision THAs and requires further investigation in many fields. Unless “the system” addresses these subtle but important differences, tertiary referral centers may be inundated with patients who need procedures that cost more to perform than the institutions receive in reimbursement—an unsustainable scenario.

It is not often that The Journal of Bone & Joint Surgery publishes an article about data-linkage efforts. To even raise the topic with most readers of The Journal would elicit a yawn and quick dismissal of the abstract without a second thought. With this fact duly noted, the possibility of linking health-system joint-replacement registries with Medicare claims data is a first step in a potentially game-changing approach to achieving the long-term clinical research our specialty needs.
In the June 20, 2018 issue of JBJS, Raman et al. detail their successful linkage of a total ankle arthroplasty (TAA) registry with Medicare data without the use of unique patient identifiers. Among 280 TAA patients over the age of 65, 250 had their registry data linked with their Medicare record with exact matches for date of procedure, date of birth, and sex. Of the linked records, 214 (76.4%) had ≥3 years of postoperative claims data.
Why are these findings so important? The answer is follow-up. Every clinician and/or researcher who has attempted to follow patients beyond the first year after a procedure understands how difficult long-term follow-up is. We live in a mobile society in which informative posttreatment data is easily lost. The younger the patient group, the more difficult it usually is to locate patients as time passes. If patients are doing well, many stop coming to our offices, no matter how strongly we recommend annual follow-ups. Everyone is busy—including retirees—and most have better things to do than drive to their surgeon’s office or even complete a web-based questionnaire. Additionally, some patients care only about their own outcomes; they are not as focused as we are on contributing to the advancement of the profession and improving outcomes at the population level.
By linking patient data from a local health-system registry to nationwide claims data, we can gain a better understanding of long-term patient progress. We can use the patient- and implant-specific data housed in the registry and essentially substitute the information from follow-up visits that did not take place within the registry system with the data contained within the Medicare system, which follows beneficiaries wherever they live.
The marriage of registry and claims data is not perfect, though, because patients who are still working probably have private insurance coverage that is not captured by the Medicare system. (Of course, if universal coverage were to come to pass, that issue would be eliminated.) Furthermore, any time claims data are used, uncertainty about the accuracy of coding must be considered. These real-world limitations notwithstanding, the linkage of registry data with claims data does have great potential for enhancing our ability to analyze—and improve—long-term orthopaedic outcomes.

The bundled-payment model has found some early success within the field of orthopaedic surgery, most notably in joint replacement (see related OrthoBuzz post), However, more robust risk-adjustment methods are needed, especially in terms of patient factors. That is the message delivered by Cairns et al. in their retrospective analysis of Medicare data from 2008 to 2012 published in the February 21, 2018 edition of JBJS. The authors make a compelling case for improved risk stratification of hip- and femur-fracture patients to ensure that all patient populations have and retain access to appropriate care.
The authors analyzed reimbursements for the surgical hospitalization and 90 days of post-discharge care among nearly 28,000 patients who met inclusion criteria for the Surgical Hip and Femur Fracture Treatment (SHFFT) model proposed by the Centers for Medicare and Medicaid Services (CMS). Their findings highlighted various inconsistencies that could have unintended consequences if not accounted for in the bundled-payment model. For example, reimbursements were $1000 to $2000 lower for patients in their 80s, who tend to have more comorbidities that require more care, than for younger patients. CMS proposed using Diagnosis Related Groups (DRGs) and geographic location to adjust for risk in its SHFFT bundled-payment model, but Cairns et al. identify several other factors (such as patient age and gender, ASA and Charlson Comorbidity Index scores, and procedure type) that could provide a more realistic stratification of risk.
The article clearly articulates how risk adjustments that don’t include more specific patient factors could lead to a multitude of unintended consequences for patients, providers, and the entire healthcare system. These findings could remain relevant now that CMS has announced an “advanced” voluntary bundled-payment model after the Trump administration cancelled SHFFT in late 2017.
Whatever bundled-payment model takes hold, the totality of the orthopaedic literature strongly suggests that the best outcomes are derived from making specific treatment plans for each patient based on the individual characteristics of his or her case. It seems reasonable that the best bundled-payment plans would do the same.

In the February 7, 2018 issue of The Journal, Lalezari et al. provide a detailed analysis of the variability in state-based Medicaid reimbursements to physicians for 10 common orthopaedic procedures, including hip and knee replacement and 5 spinal surgeries. The discrepancies in reimbursements between states, even bordering states in the same geographic region, are substantial and do not seem to follow any pattern. This phenomenon of reimbursement variability has been mentioned in podium presentations and some less comprehensive reports in the past. However, the authors of this study used a careful, methodological approach to accurately report these differences in a manner that is easy for readers to understand.
There is simply no way to rationalize this degree of variation in Medicaid reimbursement; the magnitude cannot be explained by differences in workload or practice costs because Lalezari et al. adjusted for cost of living and relative value units (RVUs). Nor does Medicaid-reimbursement variability seem to be related to Medicare reimbursement rates, as some states had Medicaid reimbursements that were higher than Medicare reimbursements for all procedures analyzed.
The orthopaedic community should not react directly to the reimbursement discrepancies presented in this article. Rather, orthopaedic surgeons, health system administrators, and patients alike should bring the variability of Medicaid reimbursements to the attention of state and federal policy makers.
Alas, I am not optimistic that this issue will gain a lot of traction given the long list of healthcare-related issues currently on the desks of state and federal lawmakers. Moreover, as the authors mention, these state-based reimbursement rates are likely related to many variables, and Lalezari et al. further observe that “health policy intended to improve access to specialty care should not solely focus on physician reimbursement.” However, consistent communication with elected officials to help explain the impact that these variable rates can have on patient care, accompanied by updated studies like this one every 2 to 4 years, would seem to be a rational response to these data.

Are you confused and frustrated by Medicare’s Quality-Incentive Programs, such as the Merit Based Incentive Payment System (MIPS), Comprehensive Care for Joint Replacement (CJR) program, and the Surgical Hip and Femur Fracture Treatment (SHFFT) model? If so, this webinar is for you.
On Tuesday, August 15, 2017 at 8:00 PM EDT, The Journal of Bone & Joint Surgery (JBJS) and the American Orthopaedic Association (AOA) will host a complimentary LIVE webinar featuring the following speakers and topics:
- Brian McCardel, MD will discuss choosing MIPS-related quality measures, improving performance on those measures, and qualifying for bonuses.
- Thomas Barber, MD, FAOA will focus on managing clinical care including how to deliver low-cost high-quality care for high-risk orthopaedic patients.
- Alexandra Page, MD will discuss partnering with hospitals and post-acute organizations to improve patient care and reap financial rewards.
Moderated by Douglas Lundy, MD, FAOA, the webinar will include a live Q&A session between the audience and panelists.
According to Medscape (registration required) and other media reports, President-Elect Donald Trump has tapped Rep. Tom Price, MD (R-GA) to be the next secretary of the US Department of Health and Human Services (HHS).
Dr. Price, an orthopaedic surgeon, became chair of the House Budget Committee in 2014, and he is a member of the GOP Doctors Caucus, which has vigorously opposed the Affordable Care Act (ACA). Dr. Price has introduced ACA-replacement legislation called the Empowering Patients First Act. Among other things, Dr. Price’s legislation would allow Medicare-eligible people to opt out of the program and purchase private health insurance using tax credits. In the bill’s latest form, people between 18 and 35 years of age would also be eligible to receive $1200 in tax credits to buy health coverage on the individual market.
Dr. Price has taken other stands on health care policy that are consistent with a small-government approach, although he did vote for the Medicare Access and CHIP Reauthorization Act (MACRA), which gradually shifts Medicare from a fee-for-service to pay-for-value system.
HHS Secretary nominees face a confirmation vote in the Senate, but by all accounts, Dr. Price’s personality will not get in the way of that. Donald Palmisano, Jr., executive director of the Medical Association of Georgia, told Medscape that Dr. Price is “approachable and accessible to political friends and foes alike.”

In a recent issue of JAMA, Dummit et al. analyzed cost and quality results from the Centers for Medicare & Medicaid Services (CMS) Bundled Payment for Care Improvement (BPCI) initiative. The authors compared joint-replacement results between hospitals that voluntarily participate in the BPCI program versus matched comparison hospitals that do not participate. Nearly 60,000 lower extremity joint replacement procedures from each hospital type were included in the analysis.
Medicare payments declined over time in both groups of hospitals, but the authors noted a greater decline in costs among the BPCI hospitals, primarily due to reduced utilization of post-institutional acute care. There were no statistical differences in quality between the BPCI hospitals and comparison hospitals, as measured by unplanned admissions, emergency department visits, and mortality at both 30 and 90 days. These results echo those reported by other pilots in the United States and suggest that similar programs could reduce cost per episode of care without compromising quality.
However, even proponents of the new programs are cautious. For example, in his JAMA editorial, Elliot Fisher, MD warns readers that because BPCI is a voluntary program, the results may not reflect the true impact of a more widespread bundled-payment model. The incentives, he argues, could end up contributing to volume increases or shifts toward healthier—and “more profitable”—patients. As Fisher concludes, “Bundled payments leave the overarching incentive to increase volume solidly in place.”
In a separate JAMA Viewpoint article, Ibrahim et al. warn that another CMS program, the Comprehensive Care for Joint Replacement (CJR) model, could unintentionally amplify already existing racial disparities in elective joint replacement. CJR is a mandatory initiative in 67 randomly selected US metropolitan areas. The authors say that CJR might improve postoperative quality of care for minority patients after joint replacement, but that the program could also end up favoring healthier, well-insured patients.
Overall, at this early stage, these two CMS models offer promising, comprehensive approaches to joint replacement that may prove cost-saving without comprising quality of care. Results like the ones published by Dummit et al. are hopeful, but longer-term, outcomes-based, and cost-focused studies that include epidemiologic and racial impact must be performed as we move forward carefully.

The answer to that question depends largely on how much the 90-day episode of care actually costs. Virk et al., in the August 17, 2016 edition of JBJS, provide benchmark data that could help policymakers design bundled payments for cervical fusions that are economically viable for providers.
The authors analyzed the Medicare 5% National Sample Administrative Database and found that 4,506 patients in that cohort underwent a one to two-level anterior cervical discectomy and fusion (ACDF) for cervical radiculopathy from 2005 to 2012. The mean cost per patient of the procedure plus the 90-day postoperative period was $15,417. The physician reimbursement represented 20.4% of that total, with the surgeon receiving 18% of the total. Reimbursements for hospitals for inpatient care represented nearly 73% of the total reimbursement. The study did not account for reimbursements from “Medigap” plans or private payers.
The authors also analyzed data from the same database for 90-day episodes of care related to total knee arthroplasty (TKA). The mean per-patient reimbursement for TKA patients was $17,451. The authors noted significant regional variation in reimbursement for ACDF, with the lowest rates in the Northeast and Midwest and the highest rates in the West.
Among the conclusions made by Virk et al. is the following: “Although payments to physicians have been implicated in the rise of health-care costs, the data suggest that the greater opportunity for reducing expenses involves hospital-related reimbursement.”

The March 16, 2016 JBJS includes a careful incidence, treatment, and outcome analysis by Pearson et al. of CMS data regarding C2 cervical-spine fractures that occurred in the Medicare population from 2000 to 2011. The study’s methodological quality comes as no surprise, as the group hails from Dartmouth, the home of the renowned Dartmouth Atlas of Health Care, which has posed many vexing clinical and cost questions for the orthopaedic community.
Pearson et al. found that while the incidence of C2 fractures in the elderly increased 135% from 2000 to 2011, the rate of surgical treatment for this injury remained essentially unchanged. I find that static rate of surgical treatment troubling, because, after controlling for potential confounders, the authors found that surgical treatment was associated with a nearly 50% decrease in 30-day mortality and a 37% decrease in one-year mortality, relative to nonoperative approaches.
I believe that our apparent reluctance to perform surgery in these cases is due to the underlying belief that upper C-spine fixation/fusion in the elderly presents a prohibitively high risk. I question that general proposition because we think quite the opposite nowadays when managing hip fractures and many other metaphyseal fractures with high complication profiles in older people. Certainly, the major risks with upper C-spine surgery are potentially fatal neurologic and vascular injuries, but this well-done analysis demonstrates that the mortality outcomes are markedly better with surgery. In addition, JBJS recently published a paper by Joestl et al. on the outcomes of C2 fusions in geriatric patients with a dens fracture nonunion, which confirmed good outcomes and a favorable risk profile (see related OrthoBuzz post).
I think it is time for the orthopaedic, neurological-spine, and rehabilitation communities to seriously reconsider our approach to elders with C2 fractures. As Pearson et al. conclude, until an RCT is performed on this question (if ever), “surgeons and patients should use the available data in a shared decision-making model to choose the treatment consistent with an individual patient’s values.”

Starting on April 1, 2016, Medicare will implement its Comprehensive Care for Joint Replacement (CJR) model in about 800 hospitals in 67 metropolitan areas around the United States. Finalized in November 2015, the CJR initiative is intended to enhance value for patients undergoing lower extremity joint replacement (LEJR) by motivating institutions to achieve quality improvement via cost control. (For a complete discussion of “value” in orthopaedics, see “Measuring Value in Orthopaedic Surgery” in JBJS Reviews.)
Medicare hopes CJR will promote standardized, coordinated care that takes each LEJR patient seamlessly through an “episode of care” that maximizes outcomes at a reduced cost. Episodes are triggered by hospital admission and are limited to admissions resulting in a discharge paid under MS-DRG 469 or 470. For CJR purposes, episodes last for 90 days following discharge.
Initially, episode target prices will be based on historical hospital-specific reimbursements, but over time, the target prices will increasingly reflect regional averages. If a hospital’s average LEJR episode cost is below the target price, it can receive a “bonus” from CMS. If its average cost is above the target price, it will owe CMS the difference. CMS has designed a gradual rollout plan to mitigate downside risk in the first year and provide current and future participants adequate time to implement evidence-based, cost-effective care and other quality programs in their institutions.
Richard Iorio, MD, chief of adult reconstruction at NYU-Langone Medical Center’s Department of Orthopaedic Surgery, says, “There will be definite winners and losers in CJR. Once geographic pricing becomes the dominant metric for target prices, there will be intense price competition in geographic areas and potential access problems for high risk patients.” At the moment, CJR stratifies risk based only on MS-DRG code and whether a patient has a hip fracture. Unless a more robust risk stratification method is implemented, “cherry-picking” patients may become a significant issue. (See related OrthoBuzz post “Tool for Pre-TJA Risk Stratification.”)
If you are an orthopaedic surgeon who performs LEJR, ask your department head or health system about CJR, because strategies that minimize cost and maximize quality may vary from hospital to hospital. Alignment of hospitals and surgeons is probably the most critical success factor with CJR. To that end, gainsharing— a key component of well-functioning hospital-surgeon partnerships within any bundled-payment environment —for individual orthopaedic surgeons is specifically allowed within the CJR final rule.
