High deductibles are associated with severe disease, catastrophic out-of-pocket payments for emergency surgical conditions.
This retrospective analysis of claims data examined the association of a high-deductible health insurance plan (HDHP) with severe disease and catastrophic out-of-pocket payments for emergency surgical conditions (e.g., appendicitis, cholecystitis, diverticulitis, and intestinal obstruction). Primary outcome was disease severity at presentation-determined using ICD-10-CM diagnoses codes and based on validated measures of anatomic severity (e.g., perforation, abscess, diffuse peritonitis). The secondary outcome was catastrophic out-of-pocket spending, defined by the World Health Organization as out-of-pocket spending >10% of annual income. Among 43,516 patients [mean age 48.4 years; 51% female], 41% were enrolled in HDHPs. Despite being younger, healthier, wealthier, and more educated, HDHP enrollees were more likely to present with more severe disease (28.5% vs 21.3%); even after adjusting for relevant demographics. HDHP enrollees were also more likely to incur 30-day out-of-pocket spending that exceeded 10% of annual income (20.8% vs 6.4%).

Incorporating added therapeutic benefit and domestic reference pricing into Medicare payment for expensive part B drugs.
The objective of this retrospective analysis was to identify expensive Part B drugs and to consider the evidence for each drug's added benefit in order to model a reimbursement policy for Medicare that integrates added benefit assessment and domestic reference pricing. Data were taken from a nationally representative sample of traditional Medicare Part B claims. The analysis showed that more than one-third of the expensive Part B drugs prescribed in 2019 offered low added benefit. The authors concluded that reference pricing based on added benefit assessment could be used to address the launch prices for expensive Part B drugs with low added benefit.

Opportunities for savings in risk arrangements for oncologic care.
High spending for cancer care is a target for savings as the United States hastens adoption of alternative payment through global payment models such as Accountable Care Organizations (ACOs) or Medicare Advantage (MA). The purpose of this study was to quantify the level at which Accountable Care Organizations ACOs and other risk-bearing organizations operating in a specific geographic area could realize savings by directing patients to efficient medical oncology practices. The incident cohort included 1,309,825 patients Options for directing differed across markets; the top quartile market had 10 or more oncology practices, but the bottom quartile had 3 or fewer oncology practices. Total spending (including Medicare Part D) in the incident cohort increased from a mean of $57,314 in 2009 to 2010 to $66,028 in 2016 to 2017. Within markets, total spending for practices in the highest spending quartile was 19% greater than in the lowest quartile. Hospital spending was the single largest component of spending in both time periods followed by Part B (infused) chemotherapy. Correlations in practice-level spending between the first-year (2009) and second-year (2010) spending were high.

Optimal care for kidney health: development of a Merit-based Incentive Payment System (MIPS) value pathway.
This article detailed the iterative consensus-building process used by the American Society of Nephrology Quality Committee to develop the Optimal Care for Kidney Health Merit-based Incentive Payment System (MIPS) Value Pathway (MVP). The Optimal Care for Kidney Health MVP, published in the 2023 Medicare Physician Fee Schedule Final Rule, included measures related to angiotensin-converting enzyme inhibitor and angiotensin receptor blocker use, hypertension control, readmissions, acute kidney injury requiring dialysis, and advance care planning. The MVP nephrology’s goal was to streamline measure selection in MIPS and served as a case study of collaborative policymaking between one professional organization and national regulatory agencies.

How does the effect of the comprehensive Care for Joint Replacement model vary based on surgical volume and costs of care?
This article described differences in costs, quality, and patient selection between hospitals that continued to participate in the comprehensive Care for Joint Replacement (CJR) program after the CMS policy revision and those that withdrew from CJR before and after the implementation of CJR. Study subjects were Medicare beneficiaries who had undergone elective lower extremity joint replacement from 2013 to 2017. The results indicated that hospitals that continued to participate in CJR achieved a greater cost reduction. The authors noted that these the cost reductions were partly attributable to the avoidance of potential higher-cost patients.

Interhospital variability in health care-associated infections and payments after durable ventricular assist device implant among Medicare beneficiaries.
The purpose of this study was to examine differences in durable ventricular assist device implantation infection rates and associated costs across hospitals. The researchers utilized clinical data for 8,688 patients who received primary durable ventricular assist devices from the Society of Thoracic Surgeons Interagency Registry for Mechanically Assisted Circulatory Support (Intermacs) hospitals (n = 120) and merged that data with post-implantation 90-day Medicare claims. The primary outcome included infections within 90 days of implantation and Medicare payments. The study found that 27.8% of patients developed 3982 identified infections. The median adjusted incidence of infections (per 100 patient-months) across hospitals was 14.3 and differed according to hospital. Total Medicare payments from implantation to 90 days were 9.0% more in high versus low infection tercile hospitals. The researchers concluded that health-care-associated infection rates post durable ventricular assist device implantation varied according to hospital and were associated with increased 90-day Medicare expenditures.

Health care leaders' perspectives on the Maryland all-payer model.
The purpose of this study was to examine perspectives on the implementation of the Maryland All-Payer Model (MDAPM) among health care leaders who participated in its design and execution. Findings identified key themes: expectations, autonomy, communication, actionable data, global budget calibration, and shared commitment to change. Together, these themes suggested that implementing the payment model followed an evolving and collaborative process that required stakeholder communication, data to guide decisions, and commitment to operating within the new payment system.

Geographic variation in Medicare fee-for-service health care expenditures before and after the passage of the Affordable Care Act.
This cross-section study examined geographic variation in Medicare fee-for-service health care expenditures before and after the passage of the Affordable Care Act. The study included all fee-for-service Medicare enrollees aged 65 and older from 2007 to 2018 using data from the Medicare Geographic Variation Public Use File. Hospital referral regions (HRRs) were grouped in each year into deciles (10 equal groups) based on per-beneficiary total spending. Geographic variation was stable from 2007 to 2011 and declined steadily from 2012 through 2018. In specific spending categories, only home health had statistically significant reductions in geographic variation. The ratio of home health spending among HRRs in the top to bottom deciles of total Medicare spending fell from 5.14 in 2007 to 3.45 in 2018.

Preparing for bundled payments: impact of complications post-coronary artery bypass grafting on costs.
This study examined the impact of complications on bundled payments for coronary artery bypass grafting (CABG) for care provided from admission through 90 days post-discharge. The authors linked clinical and internal cost data for patients undergoing CABG from 2014 to 2017 at a single institution. They performed multivariable linear regression to evaluate drivers of high costs, adjusting for preoperative and intraoperative characteristics and postoperative complications. They reviewed records of 1789 patients undergoing CABG with an average of 2.7 vessels. A large proportion of patients were diabetic and obese. Factors associated with increased adjusted costs were preoperative renal failure, diabetes and body mass index, postoperative stroke, prolonged ventilation, rebleeding requiring reoperation, and renal failure with varying magnitude.

Payment incentives and the use of higher-cost drugs: a retrospective cohort analysis of intravenous iron in the Medicare population.
Researchers examined prescribing patterns in the context of intravenous (IV) iron, for which multiple similarly safe and efficacious formulations exist, with wide variations in price. Using Medicare data, they found an increase in the dispensing of a higher-priced IV iron formulation associated with a shortage of a less expensive drug that persisted once the shortage ended. They concluded that their findings in IV iron have broader implications for Part B drug payment policy because the price of the drug determines the physician and health system payment.

Association between specialist compensation and Accountable Care Organization performance.
This study’s objective was to determine whether Medicare Shared Savings Program Accountable Care Organizations (ACOs) using cost reduction measures in specialist compensation demonstrated better performance. National cross-sectional survey data on ACOs from 2013-2015 was linked to public-use data on ACO performance from 2014-2016. Out of 160 ACOs surveys, 26% reported using cost reduction measures to help determine specialist compensation. However, these ACOs did not have savings in the short term.

New evidence of state variation in Medicaid payment policies for dual Medicare-Medicaid enrollees.
The authors developed the first longitudinal database of state Medicaid policies for paying the cost sharing in Medicare Part B for services provided to dual Medicare-Medicaid enrollees (duals), and an index summarizing the impact of these policies on payments for physician office services. Information from 2004-2018 was consolidated from online Medicaid policy documents, state laws, and policy data reported to them by state Medicaid programs. The database showed that in 2018 42 states had policies to limit Medicaid payments of Medicare cost sharing when Medicaid’s fee schedule was lower than Medicare’s. This was an increase from 36 such states in 2004. In most states, combined Medicare and Medicare payments for evaluation and management services provided to duals averaged 78% of the Medicare allowed amount for these services.

Is it time for ACOs to start tackling the high costs of surgery?
This article discusses an article appearing in the same issue revisiting the impact of Medicare Shared Savings Program (MSSP) accountable care organizations (ACOs) on surgery expenditures. The author suggests that, in order to engage even more surgeons, it is likely that MSSP ACOs will have to work with surgeons in the various Medicare bundled payment programs for surgery. He concludes that the next stage is to examine how these different programs can work together to produce even more savings in surgical care.

Can vertically integrated health systems provide greater value: the case of hospitals under the comprehensive care for joint replacement model?
The authors sought to assess whether system providers perform better than non-system providers under an alternative payment model that incentivizes high-quality, cost-efficient care. Using CMS data linked to AHRQ’s Compendium of US Health Systems, along with secondary sources, they found that when operating under alternative payment model incentives, vertical integration may enable hospitals to lower costs with similar quality scores.

Kennedy G, Lewis VA, Kundu S, Mousqués J, Colla CH. Accountable care organizations and post-acute care: a focus on preferred SNF networks.
This study examined the relationship between accountable care organizations (ACOs) and skilled nursing facilities (SNFs) for patients who are discharged from a hospital into a SNF. A mixed-method design was used and survey data was examined from 366 respondents to the National Survey of ACOs along with 16 semi-structured interviews with ACOs who performed well on cost and quality measures. Over half of ACOs had no formal relationship with SNFs; however the majority of ACO interviewees had preferred SNF networks. These preferred networks are beginning to transform the ACO post-acute care landscape.

Do financial incentives matter? Effects of Medicare price shocks on skilled nursing facility care.
The authors provided new evidence on how Medicare payment changes affect the amount of skilled nursing facility (SNF) care provided to Medicare patients. They found that increases in Medicare payment rates to SNFs increased the total number of Medicare resident days at SNFs. Further, the effects were asymmetric; although Medicare payment increases affected Medicare days, payment decreases did not. They conclude that their results have important implications for policies that alter the Medicare base payment rates to SNFs and other health care providers.

Reference-based benefits for colonoscopy and arthroscopy: large differences in patient payments across procedures but similar behavioral responses.
This study examined how reference-based benefits (RBB) affect out-of-pocket payments across outpatient procedures. The California Public Employees’ Retirement System (CalPERS) applied RBB only to outpatient procedures performed in a hospital outpatient department (HOPD) and not to outpatient procedures performed in a lower cost ambulatory surgery center. Claims from 2009-2013 on arthroscopy and colonoscopy services were analyzed. CalPERS patients paid an average of 63.9% more for HOPDs than ambulatory surgery centers in 2012, but for arthroscopy there was no statistically different cost sharing. This led to high-priced HOPDs being less likely to be chosen by CalPERS patients for both procedures.

"Surprise" out-of-network billing in orthopedic surgery: charges from surprising sources.
This study examined “surprise” out-of-network billing in orthopedic surgery. Data was analyzed from the Clinformatics DataMart on commercial insured patients undergoing 4 different elective orthopedic procedures from 2012 to 2017: arthroscopic meniscal repair, lumbar discectomy, total knee replacement and total hip replacement. They defined surprise bills as out-of-network bills for procedures done at in-network hospitals. The rate of potential surprise bills was 24.8% for total knee replacement, 24.5% lumbar discectomy, 23.5% for total hip replacement, and 12.5% for meniscal repair. The largest number of surprise bills came from anesthesiologists (39% of all episodes), and durable medical equipment (15%). Per episode, the largest bills came from nonphysician surgical assistants, neurologists, and physician assistants.

Challenges of measuring costs of care for US practices.
Investigators sought to describe the feasibility of applying claims-based cost measures included in Merit-based Incentive Payment System (MIPS) to practices nationwide, and to assess whether feasibility varies by practice size or specialty mix. They found that most practices that qualify for MIPS are small, specialist-only practices that are unable to meet minimum case requirements for MIPS’ two required cost measures, due to a combination of size and provider mix, suggesting that clinicians in small, specialist-only practices are less likely to be evaluated on cost. They stressed the importance of identifying alternative approaches to ensure that value - both quality and cost - is rewarded.

In this paper the authors discuss payment reform, global budget models and why incentives differ for health system versus physician group ACO’s. They indicate that incentives in new payment models are closely connected to the structure of the health care delivery system and that policies that ignore this relationship and focus only on the risk terms of payment contracts may miss opportunities for progress.

Differences between public and private hospital payment rates narrowed, 2012-16.
In 2000-12 payments for inpatient hospital stays, emergency department visits, and outpatient hospital care for privately insured patients grew much faster than payments for Medicare and Medicaid patients. This widening of private-public payment gaps slowed or even reversed itself in 2012-16. In this paper, the author discusses the differences between public and private hospital payment rates, 2012-2016.

The impact of Medicare copayments for skilled nursing facilities on length of stay, outcomes, and costs.
The objective of this study was to investigate the impact of Medicare's skilled nursing facility (SNF) copayment policy, with a large increase in the daily copayment rate on the 20th day of a benefit period, on length of stay, patient outcomes, and costs. The investigators concluded that Medicare's SNF copayment policy was associated with shorter lengths of stay and worse patient outcomes, suggesting the copayment policy had unintended and negative effects on patient outcomes.

Assessment of out-of-network billing for privately insured patients receiving care in in-network hospitals.
This retrospective analysis used data from the Clinformatics Data Mart database (Optum) to examine out-of-network billing among privately insured patients with an inpatient admission or emergency department (ED) visit at in-network hospitals. The investigators found that out-of-network billing appeared to have become common for privately insured patients even when they soughttreatment at in-network hospitals. They indicated that the mean amounts billed appeared to be sufficiently large that they may create financial strain for a substantial proportion of patients.

Changes in screening colonoscopy following Medicare reimbursement and cost-sharing changes.
This study examined changes in screening colonoscopy rates after Medicare reimbursement and cost-sharing changed when the Affordable Care Act (ACA) was implemented. A 20% random sample of fee-for-service (FFS) Medicare claims from 2002-2012 was used in this study. Screening colonoscopy rates did increase after 2001 when cost-sharing was eliminated but the amount varied depending on the algorithm used to classify the indication.
