In a handful of cases, health insurers reversed denials after physicians or patients posted complaints on social media
Prior authorization requirements by health insurers have long been a thorn in the side of medical laboratories, as well as physicians. But now, doctors and patients are employing a new tactic against the practice—turning to social media to shame payers into reversing denials, according to KFF Health News (formerly Kaiser Health News).
Genetic testing lab companies are quite familiar with prior authorization problems. They see a significant number of their genetic test requests fail to obtain a prior authorization. Thus, if the lab performs the test, the payer will likely not reimburse, leaving the lab to bill the patient for 100% of the test price, commonly $1,000 to $5,000. Then, an irate patient typically calls the doctor to complain about the huge out-of-pocket cost.
“There are times when you simply must call out wrongdoings,” she wrote in an Instagram post, according to the outlet. “This is one of those times.”
In response, an “escalation specialist” from BCBSIL contacted her but was unable to help. Then, after KFF Health News reached out, Nix discovered on her own that $36,000 in outstanding claims were marked “paid.”
“No one from the company had contacted her to explain why or what had changed,” KFF reported. “[Nix] also said she was informed by her hospital that the insurer will no longer require her to obtain prior authorization before her infusions, which she restarted in July.”
“I think we’re on the precipice of really improving the environment for prior authorization,” said Todd Askew, Senior Vice President, Advocacy, for the American Medical Association, in an AMA Advocacy Update. If this was to happen, it would be welcome news for clinical laboratories and anatomic pathology groups. (Photo copyright: Nashville Medical News.)
Physicians Also Take to Social Media to Complain about Denials
Some physicians have taken similar actions, KFF Health News reported. One was gastroenterologist Shehzad A. Saeed, MD, of Dayton Children’s Hospital in Ohio. Saeed posted a photo of a patient’s skin rash on Twitter in March after Anthem denied treatment for symptoms of Crohn’s disease. “Unacceptable and shameful!” he tweeted.
Two weeks later, he reported that the treatment was approved soon after the tweet. “When did Twitter become the preferred pathway for drug approval?” he wrote.
Eunice Stallman, MD, a psychiatrist from Boise, Idaho, complained on X (formerly Twitter) about Blue Cross of Idaho’s prior authorization denial of a brain cancer treatment for her nine-month-old daughter. “This is my daughter that you tried to deny care for,” she posted. “When a team of expert [doctors] recommend a treatment, your PharmD reviewers don’t get to deny her life-saving care for your profits.”
However, in this case, she posted her account after Blue Cross Idaho reversed the denial. She said she did this in part to prevent the payer from denying coverage for the drug in the future. “The power of the social media has been huge,” she told KFF Health News. The story noted that she joined X for the first time so she could share her story.
Affordable Care Act Loophole?
“We’re not going to get rid of prior authorization. Nobody is saying we should get rid of it entirely, but it needs to be right sized, it needs to be simplified, it needs to be less friction between the patient and accessing their benefits. And I think we’re on really good track to make some significant improvements in government programs, as well as in the private sector,” said Todd Askew, Senior Vice President, Advocacy, for the American Medical Association, in an AMA Advocacy Update.
However, KFF HealthNews reported that Kaye Pestaina, JD, a Kaiser Family Foundation VP and Co-Director of the group’s Program on Patient and Consumer Protections, noted that some “patient advocates and health policy experts” have questioned whether payers’ use of prior authorization denials may be a way to get around the Affordable Care Act’s prohibition against denial of coverage for preexisting conditions.
“They take in premiums and don’t pay claims,” family physician and healthcare consultant Linda Peeno, MD, told KFF Health News. “That’s how they make money. They just delay and delay and delay until you die. And you’re absolutely helpless as a patient.” Peeno was a medical reviewer for Humana in the 1980s and then became a whistleblower.
The issue became top-of-mind for genetic testing labs in 2017, when Anthem (now Elevance) and UnitedHealthcare established programs in which physicians needed prior authorization before the insurers would agree to pay for genetic tests.
Dark Daily’s sister publication The Dark Report covered this in “Two Largest Payers Start Lab Test Pre-Authorization.” We noted then that it was reasonable to assume that other health insurers would follow suit and institute their own programs to manage how physicians utilize genetic tests.
At least one large payer has made a move to reduce prior authorization in some cases. Effective Sept. 1, UnitedHealthcare began a phased approach to remove prior authorization requirements for hundreds of procedures, including more than 200 genetic tests under some commercial insurance plans.
However, a source close to the payer industry noted to Dark Daily that UnitedHealthcare has balked at paying hundreds of millions’ worth of genetic claims going back 24 months. The source indicated that genetic test labs are engaging attorneys to push their claims forward with the payer.
Is Complaining on Social Media an Effective Tactic?
A story in Harvard Business Review cited research suggesting that companies should avoid responding publicly to customer complaints on social media. Though public engagement may appear to be a good idea, “when companies responded publicly to negative tweets, researchers found that those companies experienced a drop in stock price and a reduction in brand image,” the authors wrote.
However, the 2023 “National Customer Rage Survey,” conducted by Customer Care Measurement and Consulting and Arizona State University, found that nearly two-thirds of people who complained on social media received a response. And “many patients and doctors believe venting online is an effective strategy, though it remains unclear how often this tactic works in reversing prior authorization denials,” KFF Health News reported.
Federal Government and States Step In
KFF Health News reported that the federal government is proposing reforms that would require some health plans “to provide more transparency about denials and to speed up their response times.” The changes, which would take effect in 2026, would apply to Medicaid, Medicare Advantage, and federal Health Insurance Marketplace plans, “but not employer-sponsored health plans.”
KFF also noted that some insurers are voluntarily revising prior authorization rules. And the American Medical Association reported in March that 30 states, including Arkansas, California, New Jersey, North Carolina, and Washington, are considering their own legislation to reform the practice. Some are modeled on legislation drafted by the AMA.
Though the states and the federal government are proposing regulations to address prior authorization complaints, reform will likely take time. Given Harvard Business Review’s suggestion to resist replying to negative customer complaints in social media, clinical labs—indeed, all healthcare providers—should carefully consider the full consequences of going to social media to describe issues they are having with health insurers.
Referral-kickback and bribery schemes that included medical laboratory tests bilked private insurers and government health plans out of $150 million over six-year period
Andrew Hillman, former co-owner of Next Health LLC, a network of drug and genetic-testing laboratories and pharmacies based in Dallas, who pleaded guilty in 2018 to violating federal anti-kickback laws, has been sentenced to 66 months in prison and ordered to pay $3 million in restitution for his role in Medicare fraud, money laundering, healthcare bribes, and doctor kickbacks, reported The Dallas Morning News.
Dark Daily’s sister publication The Dark Report (TDR) previously reported on the federal lawsuit filed by UnitedHealthcare (NYSE:UNH) against Next Health in 2017 for allegedly running fraudulent drug testing and doctor kickback schemes from 2012-2018 in Dallas.
The two owners of Next Health, Andrew Hillman and Semyon Narosov, pleaded guilty to “multiple medical kickback schemes in Dallas in which doctors were paid to steer patients to certain hospitals,” The Dallas Morning News reported. One scheme involved clinical laboratory test specimens that “were sent to the Next Health labs for a battery of unnecessary and expensive tests under the guise of a wellness study, court records say, and doctors were paid kickbacks for referring patients.”
Hillman and Narosov admitted to defrauding both government and private insurance through the phony “wellness” program and through a separate physician kickback scheme in which doctors were paid to refer patients to the now-closed Forest Park Medical Center (FPMC) in Dallas. In court filings, they admitted that “Next Health billed private and government health insurance plans more than $450 million between 2012 and 2018 and collected about $150 million in fraudulent proceeds,” Dallas Morning News reported.
Though Hillman’s guilty plea could have resulted in a
15-year prison sentence, he cooperated with federal investigators in the FPMC
bribery scheme investigation and for that he received a reduced sentence.
Narosov also pleaded guilty in both cases, but he has not yet been
sentenced.
Clinical laboratories were at the center of the Next Health money laundering scheme, which involved multiple shell companies, limited liability companies (LLCs) and umbrella corporations to shield the unlawful conduct from detection. And it worked for five years until 2017, when UnitedHealthcare (UHC) filed a $100 million federal lawsuit against Dallas-based Next Health and its subsidiary labs:
Additionally, two individuals also were charged: former Next
Health marketing representative Erik Bugen and Kirk Zajac.
As outlined in the lawsuit, UnitedHealthcare initially uncovered the fraud during a review of routine medical laboratory test claims to identify abnormal testing activity. Upon a deeper investigation, the insurer discovered an array of bribes and kickbacks and other potential crimes. In one illicit arrangement, Next Health sales consultants provided $50 gift cards to people who provided urine samples in a Whataburger bathroom as part of the “wellness study.”
Clinical laboratory specimens were sent to Next Health
laboratories for “multiple unnecessary and expensive drug tests that were later
billed to United and its customers,” the lawsuit states.
The lawsuit contends the defendants:
Paid bribes and kickbacks to referral sources,
including physicians, sober homes and sales consultants, in exchange for
requesting out-of-network lab services;
Billed for lab services that were not ordered by
medical providers;
Inflated claims by utilizing standing protocols
for blanket testing, regardless of patients’ medical histories, clinical
conditions, or needs;
Billed for services the defendants did not
perform; and
Billed charges the defendants never intended to
collect from patients.
Other Healthcare Frauds and Kickback Schemes Against
UnitedHealthcare
As TDR detailed in “Allegations in UHC Health Insurance Fraud Case Involve Multiple Defendants,” January 22, 2018, Hillman and several other defendants were not novices in devising healthcare kickback schemes. TDR noted the UnitedHealthcare lawsuit was the “visible tip of a large iceberg,” with the insurance giant the latest victim in a pattern of potential fraud and abuse that extended back almost a decade. Included in the laundry list of other allegedly illegal schemes was one distinctly similar to the Next Health fraud.
A year earlier, the US Attorney’s Office of the Northern District of Texas brought indictments against 21 persons affiliated with the physician-owned Forest Park Medical Center in Dallas. Next Health’s Hillman and Narosov were also included in that indictment, as well as 38 subsidiaries of U.S. Health Group, an earlier incarnation of Next Health.
The pair’s ownership and management positions within Next
Health and its subsidiaries created “an illegal scheme that was similar to the
one in place at Forrest [sic] Park,” UnitedHealthcare stated in its complaint.
The indictment alleged FPMC paid approximately $40 million
in bribes and kickbacks to physicians, recruiters, and others in exchange for
referring lucrative patients—particularly those with high-reimbursing, private
health insurance or benefits under certain federal programs—to the
out-of-network hospital.
Hillman, who was among 10 defendants who pleaded guilty before the FPMC case went to trial, testified for the government, the federal Department of Justice (DOJ) said in a statement.
In addition, seven others were convicted of conspiracy to pay or receive healthcare bribes.
“The verdict in the Forest Park case is a reminder to healthcare practitioners across the District that patients—not payments—should guide decisions about how and where doctors administer treatment,” US Attorney for the Northern District of Texas Erin Nealy Cox, JD, said in a press release announcing the guilty verdicts.
US District Court Judge John Parker,
JD, who served as US Attorney for the Northern District of Texas when the
FPMC indictments were handed down, explained the impact of fraud on the
healthcare system.
“Medical providers who enrich themselves through bribes and kickbacks are not only perverting our critical healthcare system, but they are committing a serious crime,” Parker said in a statement announcing the FPMC indictments. “Massive, multi-faceted schemes such as this one, built on illegal financial relationships, drive up the cost of healthcare for everyone and must be stopped.”
The lesson for clinical laboratory leaders is that vigilance
is key to spotting bad actors who wish to defraud the healthcare system. This
is double critical at a same time when labs are under increased scrutiny from
payers, federal and state regulators, and law enforcement.
As hospitals are forced to innovate, anatomic pathologists and medical laboratories will need to adapt to new healthcare delivery locations and billing systems
As new challenges threaten the survival of many hospitals worldwide, medical laboratories may be compelled to adapt to the needs of those transforming organizations. Those challenges confronting hospitals are spelled out in a recent report from management consulting firm McKinsey and Company with the provocative title, “The Hospital Is Dead, Long Live the Hospital!”
A team of analysts led by McKinsey senior partner Penny
Dash, MB BS, MSc, looked at nine trends affecting hospitals in North America,
Europe, Asia, and other regions. These trends, the authors contend, will force
hospitals to adopt innovations in how they are structured and how they deliver
healthcare.
Here are nine challenges hospitals face that have
implications for medical laboratories:
1. Aging Patient Populations
“Patient populations are getting older, and their needs are becoming more complex,” McKinsey reports, and this is imposing higher cost burdens. The US Census Bureau projects that by 2030 approximately 20% of the US population will be 65 or older compared with about 15% in 2016.
The federal Centers for Medicare and Medicaid Services (CMS) reports that this age group accounts for a disproportionate share of healthcare costs. In 2014, CMS states, per-capita healthcare spending was $19,098 for people 65 or older compared with $7,153 for younger adults.
2. Patients Are Behaving More Like Consumers
“Patients—along with their families and caregivers—expect to
receive more information about their conditions and care, access to the newest
treatments, and better amenities,” McKinsey reports.
Clinical advances are increasing the range of treatments that can be performed in outpatient settings, McKinsey reports. The authors point to multiple studies suggesting that patients can receive better outcomes when more care is delivered outside the hospital. Dark Daily has often reported on the impact of this trend, which has reduced demand for in-hospital laboratory testing while increasing opportunities for outpatient services.
4. Move Toward High-Volume Specialist Providers
Compared with general hospitals, specialized, high-volume “centers
of excellence” can deliver better and more cost-effective care in many
specialties, McKinsey suggests. As evidence, the report points to research
published over the past 12 years in specialist journals.
Some US employers are steering patients to top-ranked providers as part of their efforts to reduce healthcare costs. For example, Walmart (NYSE:WMT) pays travel costs for patients to undergo evaluation and treatment at out-of-state hospitals recognized as centers of excellence, which Dark Daily reported on in July.
UnitedHealthcare’s new preferred lab network also appears to be a nod toward this trend. As The Dark Report revealed in April, the insurer has designated seven laboratories to be part of this network. These labs will offer shorter wait times, lower costs, and higher quality of care compared with UnitedHealthcare’s larger network of legacy labs, the insurer says.
5. Impact of Clinical Advances
Better treatments and greater understanding of disease
causes have led to significantly lower mortality rates for many conditions,
McKinsey reports. But the authors add that high costs for new therapies are
forcing payers to contend with questions about whether to fund them.
As Dark Daily has often reported, new genetic therapies often require companion tests to determine whether patients can benefit from the treatments. And these also face scrutiny from payers. For example, in January 2018, Dark Daily reported that some insurers have refused to cover tests associated with larotrectinib (LOXO-101), a new cancer treatment.
6. Impact of Disruptive Digital Technologies
The McKinsey report identifies five ways in which digital
technologies are having an impact on hospitals:
Automation of manual tasks;
More patient interaction with providers;
Real-time management of resources, such as use of hospital beds;
Real-time clinical decision support to enable more consistency and timeliness of care; and
Use of telemedicine applications to enable care for patients in remote locations.
All have potential consequences for medical laboratories, as Dark Daily has reported. For example, telepathology offers opportunities for pathologists to provide remote interpretation of blood tests from a distance.
7. Workforce Challenges
Many countries are contending with shortages of physicians,
nurses, and allied health professionals, McKinsey reports. The authors add that
the situation is likely to get worse in the coming decades because much of the current
healthcare workforce consists of baby boomers.
An investigation published in JAMA in May indicated that, in the US, the number of active pathologists decreased from 15,568 to 12,839 between 2007 and 2017. In January, Dark Daily reported that clinical laboratories are also dealing with a generational shift involving medical technologists and lab managers, as experienced baby boomers who work in clinical laboratories are retiring.
8. Financial Challenges
In the United States and other countries, growth in
healthcare spending will outpace the gross domestic product, the McKinsey
report states, placing pressure on hospitals to operate more efficiently.
9. More Reliance on Quality Metrics
McKinsey cites regulations in Canada, Scandinavia, and the UK that require hospitals to publish quality measurements such as mortality, readmittance, and infection rates. These metrics are sometimes linked to pay-for-performance programs, the report states. In the United States, Medicare regularly uses quality-of-care metrics to determine reimbursement, and as Dark Daily reported in July, a new Humana program for oncology care includes measurements for medical laboratories and anatomic pathology groups.
The McKinsey report reveals that several trends in
healthcare are forcing healthcare leaders to adopt new strategies for success.
The report’s authors state that their “results show that contemporary
healthcare providers around the world are facing several urgent imperatives: to
strengthen clinical quality; increase the delivery of personalized,
patient-centered care; improve the patient experience; and enhance their
efficiency and productivity.”
These pressures on hospitals typically also require
appropriate responses from clinical laboratories and anatomic pathology groups
as well.
“Pathologists and medical laboratories may have to demonstrate efficiency and effectiveness to stay in the insurer’s networks and get paid for their services
In recent years, Medicare officials have regularly introduced new care models that include quality metrics for providers involved in a patient’s treatment. Now comes news that a national health insurer is launching an innovative cancer-care model that includes quality metrics for medical laboratories and anatomic pathology groups that deliver diagnostic services to patients covered by this program.
Anatomic pathologists and clinical laboratories know that cancer patients engage with many aspects of healthcare. And that, once diagnoses are made, the continuum of cancer care for these patients can be lengthy, uncomfortable, and quite costly. Thus, it will be no surprise that health insurers are looking for ways to lower their costs while also improving the experience and outcomes of care for their customers.
To help coordinate care for cancer patients while simultaneously addressing costs, Humana, Inc., (NYSE:HUM) has started a national Oncology Model-of-Care (OMOC) program for its Medicare Advantage and commercial members who are being treated for cancer, Humana announced in a press release.
What’s important for anatomic pathologists and clinical
laboratories to know is that the program involves collecting performance
metrics from providers and ancillary services, such as clinical laboratory,
pathology, and radiology. These metrics will determine not only if doctors and
ancillary service providers can participate in Humana’s networks, but also if
and how much they get paid.
Anatomic pathologists and medical laboratory leaders will want to study Humana’s OMOC program carefully. It furthers Humana’s adoption of value-based care over a fee-for-service payment system.
How Humana’s OMOC Program Works
According to Modern Healthcare, “Humana will be looking at several measures to determine quality of cancer care at the practices including inpatient admissions, emergency room visits, medications ordered, and education provided to patients on their illness and treatment.”
As Humana initiates the program with the first batch of
oncologists and medical practices across the US, it also will test performance criteria
that anatomic pathologist groups will need to meet to participate in the
insurer’s network and be paid for services.
The insurer’s metrics address access to care, clinical status assessments, and patient education. Physicians can earn rewards for enhancing their patients’ navigation through healthcare, while addressing quality and cost of care, reported Health Payer Intelligence.
Humana claims its OMOC quality and cost measurements are
effective in the areas of:
inpatient admissions,
emergency room visits,
medical and pharmacy drugs,
laboratory and pathology services, and
radiology.
To help cover reporting and other costs associated with
participation in the OMOC program, Humana is offering physician practices
analytics data and care coordinating payments, notes Modern Healthcare.
“The practices that improve their own performance over a one-year period will see the care coordination fee from Humana increase,” Julie Royalty, Humana’s Director of Oncology and Laboratory Strategies, told Modern Healthcare.
Value-Based Care Programs are Expensive
Due to the cost of collecting data and increasing staff capabilities to meet program parameters, participating in value-based care models can be costly for medical practices, according to Scottsdale, Ariz.-based Darwin Research Group (DRG), which studies emerging payer models.
Some of the inaugural medical practices in the Humana OMOC
include:
Southern Cancer Center, Alabama;
US Oncology Network, Arizona;
Cancer Specialists of North Florida;
Michigan Healthcare Professionals;
University of Cincinnati Physicians Company; and
Center for Cancer and Blood Disorders, Texas.
Other Payers’ Value-Based Cancer Care Programs
“Depending upon which part of the country you’re in,
alternative payment models in oncology are becoming the norm not the exception,”
noted the DRG study. “Humana is a little late to the party.”
Darwin Research added that Humana may realize benefits from
having observed other insurance company programs, such as:
Humana has developed other value-based bundled payment
programs as well. It has episode-based
models that feature open participation for doctors serving Humana Medicare
Advantage members needing:
total hip or knee joint replacement (available
nationwide since 2018); and
spinal fusion surgery (launched in 2019).
Humana also started a maternity episode-of-care bundled
payment program last year for its commercial plan members.
In fact, more than 1,000 providers and Humana value-based
relationships are in effect. They involve more than two-million Medicare
Advantage members and 115,000 commercial members.
Clearly, Humana has embraced value-based care. And, to
participate, anatomic pathology groups and medical laboratories will need to be
efficient and effective in meeting the payer’s performance requirements, while
serving their patients and referring doctors with quality diagnostic services.
Clinical laboratories could offer services that complement SDH programs and help physicians find chronic disease patients who are undiagnosed
Insurance companies and healthcare providers increasingly consider social determinants of health (SDH) when devising strategies to improve the health of their customers and affect positive outcomes to medical encounters. Housing, transportation, access to food, and social support are quickly becoming part of the SDH approach to value-based care and population health.
For clinical laboratory managers and pathologists this rapidly-developing trend is worth watching. They can expect to see more providers and insurers in their communities begin to offer these types of services to individuals and patients who might stay healthier and out of the hospital as a result of SDH programs. Clinical laboratories should consider strategies that help them provide medical lab testing services that complement SDH programs.
Medical laboratories, for example, could participate by offering
free transportation to patient
service centers for homebound chronic disease patients who need regular
blood tests. Such community outreach also could help physicians identify people
with chronic diseases who might otherwise go undiagnosed.
Anthem Offers Social
Determinants of Health Package
In fact, health benefits giant Anthem, Inc. (NYSE:ANTM) partly attributes its 2019 first quarter 14% increase of Medicare Advantage members to a new “social determinants of health benefits package” comprised of healthy meals, transportation, adult day care, and homecare, according to Forbes.
“Our focus on caring for the whole person is designed to deliver
better care and outcomes, reduce costs, and ultimately accelerate growth,” Gail Boudreaux,
Anthem President and CEO, stated in a call to analysts, Forbes reports.
An Anthem news release states that SDH priorities for payers, providers, and other stakeholders should focus on enhancing individuals’ access to food, transportation, and social support.
CMS Expands Medicare
Advantage Plans to Include Social Determinants of Health
The Centers for Medicare and Medicaid Services announced that, effective in 2019, Medicare Advantage plans can offer members benefits that address social determinants of health. Medicare Advantage members may be covered for services such as adult day care, meal delivery, transportation, and home environmental services that relate to chronic illnesses.
Humana’s ‘Bold Goal’
Humana, Inc. (NYSE:HUM) calls its SDH focus the BoldGoal. The program aims to improve health in communities it serves by 20% by 2020.
“The social barriers and health challenges that our Medicare Advantage members and others face are deeply personal. This requires us to become their trusted advocate that can partner with them to understand, navigate, and address these barriers and challenges,” said William Shrank, MD, Humana’s Chief Medical Officer, in a news release.
UnitedHealthcare
Investing More than $400 Million in Housing
Meanwhile, since 2011, UnitedHealthcare (NYSE:UNH) also has invested in affordable housing and social determinants of health, Health Payer Intelligence reported.
In a news release, UnitedHealthcare, the nation’s largest health insurer, described how it is investing more than $400 million in 80 affordable US housing communities, including:
$12 million, PATH Metro Villas, Los Angeles;
$11.7 million, Capital Studios, Austin;
$14.5 million allocated to Minneapolis military
veterans housing;
$7.9 million, New Parkridge (in Ypsilanti, Mich.)
affordable housing complex;
$21 million earmarked to Phoenix low- and moderate-income
families needing housing and supportive services;
$7.8 million, Gouverneur Place Apartments, Bronx,
New York; and
$7.7 million, The Vinings, Clarksville, Tenn.
“Access to safe and affordable housing is one of the
greatest obstacles to better health, making it a social determinant that
affects people’s well-being and quality of life. UnitedHealthcare partners with
other socially minded organizations in helping make a positive impact in our
communities,” said Steve Nelson,
UnitedHealthcare’s CEO, in the news
release.
According to the American Hospital Association (AHA) and the Health Research and Educational Trust (HRET), housing, or lack of it, impacts health. In “Housing and the Role of Hospitals,” the second guide in the organizations’ “Social Determinants of Health Series,” AHA and HRET state that 1.48 million people are homeless each year, and that unstable living conditions are associated with less preventative care, as well as the propensity to acquire diabetes, cardiovascular disease, chronic obstructive pulmonary disorder, and other healthcare conditions.
Social determinants of health programs are gaining in
popularity. And as they become more robust, proactive clinical laboratory
leaders may find opportunities to work with insurers and healthcare providers
toward SDH goals to help healthcare consumers stay healthy, as well as reducing
unnecessary hospital admissions and healthcare costs.
