 Introduction This study assesses the associations between the recent implementation of robust features of state Prescription Drug Monitoring Programs and the abrupt discontinuation of long-term opioid therapies. Methods Data were from a national commercial insurance database and included privately insured adults aged 18–64 years and Medicare Advantage enrollees aged ≥65 years who initiated a...

 ABSTRACT Objectives: Anesthesiology services are a focal point of policy making to address surprise medical billing. However, allowed amounts and charges for anesthesiology services have been understudied due to the specialty's unique conversion factor (CF) unit of payment and complex provider structures involving anesthesiologists and certified registered nurse anesthetists (CRNAs). This st...

ABSTRACT Objectives: To describe the association between the form of hospitals' contracts—either markup from a benchmark or a discount from a list price—and performance: price, charge, cost, and length of stay. Study Design: Retrospective observational study using administrative claims data matched with hospital characteristics from the American Hospital Association Annual Survey and the Healthcar...

Abstract: Patients with sickle cell disease (SCD) or cancer with bone metastasis often present to the emergency department (ED) for treatment of severe pain, and opioid analgesics remain first-line therapies for acute pain in the ED or after discharge. Policies aimed at improving the safety of opioid prescribing, such as state legislative mandates that prescribers register with or u...

Abstract:  IMPORTANCE  By 2020, nearly all states had adopted oncology parity laws in the US, ensuring that patients in fully insured private health plans pay no more for orally administered anticancer medications (OAMs) than infused therapies. Between 2013 and mid-2017, 11 states implemented parity with out-of-pocket spending caps, which may further reduce patient out-of-pocket spending...

Summary The price of childbirth in New York City varies multifold, depending on where a woman delivers. This variation in price across boroughs, and across providers within boroughs, might make sense if it corresponded to higher-quality care. But higher prices do not always signify better quality. This report examines variation in what is paid for childbirth in each of the five boroughs of New Yor...

Abstract: Private equity firms have increasingly acquired physician practices, and particularly dermatology practices. Analyzing commercial claims from the Health Care Cost Institute (2012–17), we used a difference-in-differences design within an event study framework to estimate the prevalence of private equity acquisitions and their impact on dermatologist prices, spending, utilization, and volu...

Abstract: We analyze selection into screening in the context of recommendations that breast cancer screening start at age 40. Combining medical claims with a clinical oncology model, we document that compliers with the recommendation are less likely to have cancer than younger women who select into screening or women who never screen. We show this selection is quantitatively important: shifting th...

 Abstract:  Objectives: To quantify the proportion of health plan spending on services for which surprise billing is common—provided by radiologists, anesthesiologists, pathologists, emergency physicians, emergency ground ambulances, and emergency outpatient facilities—and estimate the potential impact of proposed policies to address surprise billing on health insurance premiums. Study D...

Abstract:  Changes in the way health insurers pay healthcare providers may not only directly affect the insurer's patients but may also affect patients covered by other insurers. We provide evidence of such spillovers in the context of a nationwide Medicare bundled payment reform that was implemented in some areas of the country but not in others, via random assignment. We estimate that ...

Abstract: There is abundant literature on efforts to reduce opioid prescriptions and misuse, but comparatively little on the treatment provided to people with opioid use disorder (OUD). Using claims data representing 12–15 million nonelderly adults covered through commercial group insurance during the period 2008–17, we explored rates of OUD diagnoses, treatment patterns, and spending. We found th...

Abstract:  We analyzed the relationship between prices paid to 30,549 general internal medicine physicians and the cost and quality of care for 769,281 commercially insured adults. The highest-price physicians were paid more than twice as much per service, on average, as the lowest-price physicians were. Total annual costs for patients of the highest-price physicians were $996 (20 percent) hi...

Abstract:  Any Willing Provider (AWP) regulations require insurers to allow health care providers network membership, eliminating an insurer's ability to commit to a limited network of providers. We study the effect of AWP on prices negotiated between insurers and providers by exploiting the introduction of a regulation targeting retail pharmacies in the state of Maine. Using insurance c...

Abstract:  Patients treated at in-network facilities can involuntarily receive services from out-of-network providers, which may result in "surprise bills." While several studies report the surprise billing prevalence in emergency department and inpatient settings, none document the prevalence in ambulatory surgery centers (ASCs). The extent to which health plans pay a portion or all of out-o...

Spending per person in employer-sponsored plans reaches all-time high of $6,335 Health care spending for the average New Yorker with employer-sponsored health insurance is increasing faster in New York State than the rest of the country, according to a new analysis released today by the New York State Health Foundation (NYSHealth) and the Health Care Cost Institute (HCCI). Per-person spending grew...

Abstract: We compare health care spending in public and private Medicare using newly available claims data from Medicare Advantage (MA) insurers. MA insurer revenues are 30 percent higher than their health care spending. Adjusting for enrollee mix, health care spending per enrollee in MA is 9 to 30 percent lower than in Traditional Medicare (TM), depending on the way we define "comparable" enrolle...

Abstract Background: Area-level deprivation is associated with multiple adverse birth outcomes. Few studies have examined the mediating pathways through which area-level deprivation affects these outcomes. The objective of this study was to investigate the association between area-level deprivation and preterm birth, and examine the mediating effects of maternal medical, behavioural, and psyc...

ABSTRACT We examined the growth in health spending on people with employer-sponsored private insurance in the period 2007–14. Our analysis relied on information from the Health Care Cost Institute data set, which includes insurance claims from Aetna, Humana, and UnitedHealthcare. In the study period private health spending per enrollee grew 16.9 percent, while growth in Medicare spending per fee-f...

​Abstract: In 2014, insurers paid an average of 13–14 percent less for in-network mental health services in their commercial and Medicare Advantage plans than fee-for-service Medicare paid for identical services—despite paying up to 12 percent more than Medicare when the same services were provided by other physician specialties. However, patients went out of network more frequently for mental hea...

Abstract: Evidence suggests that growth in providers' prices drives growth in health care spending on the privately insured. However, existing work has not systematically differentiated between the growth rate of hospital prices and that of physician prices. We analyzed growth in both types of prices for inpatient and hospital-based outpatient services using actual negotiated prices paid by insure...

 Abstract Background: More than half of all medical procedures performed in the United States occur in an outpatient setting, yet few studies have explored how competition among ambulatory surgery centers (ASCs) and hospitals affects prices for commercially insured outpatient services. Objectives: We examined the association between prices for commercially insured outpatient procedu...

ABSTRACT   BACKGROUND: The health care costs associated with treating autism spectrum disorder (ASD) in children can be substantial. State-level mandates that require insurers to cover ASD-specific services may lessen the financial burden families face by shifting health care spending to insurers. METHODS: We estimated the effects of ASD mandates on out-of-pocket spending, insurer spendi...

Executive Summary: High and rising health care prices play a major role in the persistent increases in health care spending. This study, undertaken by the American Academy of Actuaries Health Practice Council, explores the potential for reference pricing to counter high health care prices and contain health care spending growth. Reference pricing is a system in which an insurer selects a price it ...

Abstract: Intensity-modulated radiation therapy (IMRT) is an important driver of rising costs in oncology care, but the level of evidence supporting its routine use varies across disease sites, including breast, lung, and prostate. While Medicare Advantage (MA) plans have incentives to reduce health care spending, the effect of MA enrollment on utilization of high-cost medical services and quality...

 ABSTRACT: Policies and practices have proliferated to optimize prescribers' use of their states' prescription drug monitoring programs, which are statewide databases of controlled substances dispensed at retail pharmacies. Our study assessed the effectiveness of three such policies: comprehensive legislative mandates to use the program, laws that allow prescribers to delegate its use to offi...
