Monterey DA Prosecutes Biggest Fraud Case Yet

Several years ago, Monterey County Managing Deputy District Attorney Ed Hazel obtained grant funding from the California Department of Insurance for the DA’s office to create a Disability and Healthcare Fraud Unit to combat this specialized criminal issue. The unit pursues cases involving billing fraud, false disability claims, embezzlement, identity theft to secure healthcare benefits, prescription fraud, inflated or falsified pharmacy billing, outpatient surgery center fraud, and more.

According to the report in the Californian, some of the most common cases that the unit handles involve pharmacy fraud and identity theft in which someone will go to a hospital and pretend to be someone else in order to get treatment or a prescription under the other person’s name. This can create expensive problems for the actual person whose insurance is billed and even potentially dangerous issues as medical problems are recorded for a person when they don’t apply to them in reality.

“Identity theft has the clearest example where the real danger lies,” Hazel said. “It could lead to somebody being diagnosed with something that they don’t have. It could lead to a misdiagnosis.”

In July 2014, police officers responded to the Community Hospital of the Monterey Peninsula after a doctor noticed that a person seeking emergency care had been treated before under a different name. The man, Julian Rosario, continued to ask for Vicodin and eventually admitted to using a false name to receive treatment and avoid paying the hospital bill that included charges totaling $16,829.

Two weeks later, the same doctor recognized Rosario again and called police. After further investigation, it was found that Rosario had used pharmacy fraud and identity theft to receive treatments totaling $73,653. In the end, he pleaded guilty to six felonies and three misdemeanors and was sentenced to five years of probation in a plea deal.

Monterey County District Attorney Dean D. Flippo selected Deputy District Attorney Amy Patterson as the prosecutor for the unit, and for the past three years, Patterson has prosecuted 28 cases related to healthcare fraud, many of which are fairly complex and time-consuming.

The unit is now involved with its biggest case so far with Dr. Steven Mangar, who has been charged with 37 felonies related to healthcare fraud and unlawful prescriptions. Mangar’s office manager Maria “Aloha” Eclavea also faces 23 felonies related to the alleged health insurance fraud scheme. Their preliminary hearing is scheduled for August. That case alone involved about two years of investigation as well as the review of tens of thousands of pieces of evidence.

Lengthy investigation is often necessary “to grasp the intricacies of the fraud that may happen,” Patterson said, and as such, the unit may only prosecute one or two of the larger cases each year. “Sometimes we have to triage to decide how to do the most with our resources,” Hazel added, and if the problem becomes greater than the unit can handle, additional investigators may be brought in.

Study Says 570 Clinics Offer “Unapproved” Stem Cell Procedures

According to a new study.more than 300 companies are marketing unapproved stem cell procedures at more than 500 clinics in the U.S.

Found in embryos, umbilical cord blood and adult bone marrow, stem cells have the potential to develop into any type of specialized cell in the body. Stem cells can be used to help repair areas damaged by disease or injury, according to the U.S. Department of Health and Human Services.

In the U.S., stem cell therapies generally require Food and Drug Administration approval before they can be marketed, and the FDA has only approved one product so far, for blood disorders.

But, according the study summarized in Reuters Health, many clinics in the U.S. now advertise a variety of stem cell treatments that have not been approved, ranging from cosmetic procedures like facelifts and breast enlargement, to therapies for neurological diseases or sports injuries, according to the new study. “Many of these marketing claims raise significant ethical issues given the lack of peer-reviewed evidence that advertised stem cell interventions are safe and efficacious for the treatment of particular diseases,” the researchers write in the journal Cell Stem Cell.

Searching the internet, the researchers found 351 companies marketing unapproved stem cell procedures at 570 clinics in the U.S., most commonly in California, Florida, Texas, Colorado, Arizona and New York.

These procedures are not heavily regulated because they use cells from a patient’s own body. But earlier this year, the FDA issued draft guidelines asserting that the stem cells used in most procedures are drugs and should require a rigorous approval process before they can be used. The draft guidelines will be discussed further at a public hearing in mid-September.

Unapproved stem cell therapies have no conclusive evidence of safety or effectiveness, Turner said. “If you’re thinking about having an unapproved stem cell treatment, there are things you can look for,” he said. “If a place offers one treatment for 30 to 40 diseases, it’s extremely unlikely that it’s going to be effective.”

He said he doesn’t mean to suggest that all uses of stem cells are dangerous or unethical, as approved stem cell treatments for conditions like leukemia can be life-saving.

“It is the wild west, there are lots of clinics making all kinds of promises they can’t necessarily deliver on,” said Mary Ann Chirba, professor of legal reasoning, research and writing at Boston College Law School, who was not part of the new study. “But that’s not to say that all clinicians who are working in this area are charlatans.”

There’s a “clumsy architecture” for regulating emerging therapies, Chirba told Reuters Health by email. “Any responsible person, myself included, wants regulation,” but the rules currently in place are not effective, and the draft FDA guidelines may actually be too restrictive, and make it too difficult for patients to get access to these types of treatment at all, she said.

In the meantime, the FDA cautions on its web site, “If you are considering stem cell treatment in the U.S., ask your physician if the necessary FDA approval has been obtained or if you will be part of an FDA-regulated clinical study. This also applies if the stem cells are your own. Even if the cells are yours, there are safety risks, including risks introduced when the cells are manipulated after removal.”

Medical treatment in the California Workers’ Compensation system is subject to the UR/IMR review process which will use evidence based treatment guidelines as a standard. Certainly, any request for authorization of a stem cell procedure should undergo review.

DWC Issues Drug Formulary Interim Status Report

The Division of Workers’ Compensation has posted an interim status report on its efforts to promulgate regulations for an evidence-based workers’ compensation drug formulary as required by Assembly Bill 1124. The drug formulary must be adopted by July 1, 2017, and must be consistent with California’s Medical Treatment Utilization Schedule (MTUS), for medications prescribed in the workers’ compensation system.

Assembly Bill 1124 (Statutes 2015, Chapter 525) requires DWC adopt the evidence-based workers’ compensation drug formulary in consultation with the Commission on Health and Safety and Workers’ Compensation, and that DWC’s administrative director meet and consult with stakeholders. The legislation further requires posting of a minimum of two interim reports describing the status of the formulary’s creation.

The goal is to adopt an evidence-based drug formulary, consistent with California’s Medical Treatment Utilization Schedule (MTUS), to augment the provision of high-quality medical care, maximize health, and promote return to work in a timely fashion, while reducing administrative burden and cost.

The report says that the DWC has been considering a variety of approaches to the formulary in light of the goals and preliminary criteria. In consultation with RAND, the DWC has been gathering information from workers’ compensation system participants, as well as other jurisdictions and payment systems, to identify formulary issues and best practices.

After AB 1124 was passed, a public meeting was held on February 17, 2016, to discuss its implementation. RAND researcher Barbara Wynn presented an overview of the formulary project. All stakeholders had the opportunity to provide input on development of the formulary and implementation of the bill.

The Director of the Department of Industrial Relations Christine Baker, DWC Acting Administrative Director George Parisotto, and DWC Executive Medical Director Raymond Meister, M.D., testified at the state capitol before committees of the Senate Labor and Industrial Relations Committee and the Assembly Insurance Committee. The March 2, 2016, hearing on “Implementing AB 1124 (2015): A Joint Hearing of the Senate Labor and Industrial Relations Committee and Assembly Insurance Committee on the Creation of a Workers’ Compensation Formulary” provided an opportunity for the Department to present the legislature and the public with a status report and overview of issues involved in developing the formulary.

The DWC is considering the input from stakeholders and evaluating information and analysis provided by RAND. Within the next few weeks, the DWC is expected to open another public comment period to allow all interested stakeholders to present further input on the development of a formulary. The DWC will post draft formulary regulations and the pre-publication RAND formulary report on the DWC Forum webpage for public review and discussion. Formal rulemaking is expected to begin later this year so that the formulary can be adopted before the July 1, 2017, statutory deadline.

While workers’ compensation pharmacy benefit managers have been utilizing drug formularies for a long time, only Washington, Texas, Ohio and Oklahoma have state-regulated drug formularies in place. The recent success of the closed pharmacy formulary in the Texas workers’ comp system shows promise for other states, especially in regions where non-formulary drugs are prevalent. A report from the Workers Compensation Research Institute concludes that, all things being equal, other states could see similar results.

Additional information on implementation of the drug formulary is posted on DWC’s forum and MTUS webpages.

Obamacare Insurers Forced to File Litigation for “Risk-Corridor” Funds

Insurers helped cheerlead the creation of Obamacare, with plenty of encouragement. Six years later, profit expectations have failed to materialize. Now some insurers want taxpayers to provide them the anticipated profits through lawsuits.

Earlier this month, Blue Cross Blue Shield of North Carolina and Moda Health Plan joined a growing list of insurers suing the Department of Health and Human Services in the U.S. Court of Federal Claims for more subsidies from the risk-corridor program. Congress set up the program to indemnify insurers who took losses in the first three years of Obamacare with funds generated from taxes on “excess profits” from some insurers. The point of the program was to allow insurers to use the first few years to grasp the utilization cycle and to scale premiums accordingly.

As with most of the ACA’s plans, this soon went awry. Utilization rates went off the charts, in large part because younger and healthier consumers balked at buying comprehensive coverage with deductibles so high as to guarantee that they would see no benefit from them. The predicted large windfall from “excess profit” taxes never materialized, but the losses requiring indemnification went far beyond expectations.

In response, HHS started shifting funds appropriated by Congress to the risk-corridor program, which would have resulted in an almost-unlimited bailout of the insurers. Senator Marco Rubio led a fight in Congress to bar use of any appropriated funds for risk-corridor subsidies, which the White House was forced to accept as part of a budget deal. As a result, HHS can only divide up the revenues from taxes received through the ACA, and that leaves insurers holding the bag.

They now are suing HHS to recoup the promised subsidies, Moda Health is seeking $180 million in Patient Protection and Affordable Care Act (PPACA) risk corridors program payments. North Carolina Blue is seeking $147.5 million in payments. Health Republic Insurance Company of Oregon was the first carrier to sue the USA over the USA’s PPACA risk corridors payment programs. Health Republic said it was owed a total of $22.1 million in risk corridors program money for 2014 and 2015, and it sued for about $5 billion in payments on behalf of all affected insurers. Highmark, a big Blue Cross and Blue Shield carrier in Pennsylvania, sued for $223 million in May.

But HHS has its hands tied, and courts are highly unlikely to have authority to force Congress to appropriate more funds. In fact, the Centers for Medicare and Medicaid Services formally responded by telling insurers that they have no requirement to offer payment until the fall of 2017, at the end of the risk-corridor program.

That response highlights the existential issue for both insurers and Obamacare. The volatility and risk was supposed to have receded by now. After three full years of utilization and risk-pool management, ACA advocates insisted that the markets would stabilize, and premiums would come under control. Instead, premiums look set for another round of big hikes for the fourth year of the program. Consumers seeking to comply with the individual mandate will see premiums increase on some plans from large insurers by as much as 30 percent in Oregon, 32 percent in New Mexico, 38 percent in Pennsylvania, and 65 percent in Georgia.

Thus far, insurers still claim to have confidence in the ACA model – at least, those who have not pulled out of their markets altogether. However, massive annual premium increases four years into the program demonstrate the instability and unpredictability of the Obamacare model, and a new study from Mercatus explains why.

The claims costs for qualified health plans (QHPs) within the Obamacare markets far outstripped those from non-QHP individual plan customers grandfathered on their existing plans – by 93 percent. They also outstripped costs in group QHP plans by 24 percent. In order to break even without reinsurance subsidies (separate from the risk-corridor indemnification funds), premiums would need to have been 31 percent higher on average for individual QHPs.

DWC Posts Adjustments to OMFS/DMEPOS Fees

The Division of Workers’ Compensation (DWC) has posted an order adjusting the Durable Medical Equipment, Prosthetics, Orthotics and Supplies (DMEPOS) section of the Official Medical Fee Schedule to conform to the third quarter 2016 changes in the Medicare payment system, as required by Labor Code section 5307.1.

The update includes all changes identified in Center for Medicare and Medicaid Services Change Request (CR) number 9642.

The CMS issues instructions for implementing and/or updating DMEPOS payment amounts on a semiannual basis (January and July), with quarterly updates as necessary (April and October). Updates to the codes adjusted using information from the competitive bidding program (CBP) will be made each time the payment amounts under the CBPs are adjusted or additional CBPs or payment amounts are established for the items and services. When applicable, these updates will be included in the quarterly DMEPOS change request instructions. The DMEPOS fee schedule is provided to DME MACs, the Pricing, Data Analysis and Coding Contractor (PDAC), Part A MACs, HHH MACs and Part B MACs via CMS’ mainframe telecommunication system.

The DMEPOS fee schedules are calculated by CMS. A separate DMEPOS Fee Schedule file is released to the intermediaries, regional home health intermediaries, Railroad Retirement Board (RRB), Indian Health Service and United Mine Workers. The fee schedule for parenteral and enteral nutrition (PEN) is released to the PDAC and DME MACs in a separate file. These files are also available through the CMS Website for interested parties like the State Medicaid agencies and managed care organizations.

The order, effective for services on or after July 1, 2016, adopts the Medicare DMEPOS quarterly update for calendar year 2016.

The order adopting the Official Medical Fee Schedule adjustment is posted online

Federal Judge Disqualifies SCIF Attorneys in Drobot RICO Case

A federal judge reaffirmed the disqualification of the State Fund attorneys, Hueston Hennigan, from the $160 million medical fraud case it brought three years ago on behalf of its now-former client in the massive racketeering case.

The 75-page ruling filed last week details how the concurrent representation of the State Fund and at the same time defends Paul Randall in his criminal case betrayed both parties, created “incestuous” twists (Pg. 37) and was anathema to the adversarial legal system.

The defendants in the SCIF civil litigation that started in 2013 stand accused of conspiring to defraud the State Compensation Insurance Fund by submitting fraudulent insurance bills and providing or receiving illegal kickbacks. The litigation arising out of this purported scheme involves dozens of defendants, two civil suits and a criminal suit, and well over a thousand filings spanning three years and three dockets. SCIF was at first represented by law the firm of Irell & Manella LLP. In January 2015, John Hueston and Brian Hennigan, along with thirty or so other lawyers, left Irell & Manella to form Hueston Hennigan. There Hueston and other lawyers continued to represent SCIF.

The U.S. Department of Justice filed criminal charges against some of these defendants for the same kickback scheme. One of them, Paul Richard Randall, 56, of Orange, California, a health care marketer previously affiliated with Pacific Hospital and Tri-City Regional Medical Center in Hawaiian Gardens, pleaded guilty on April 16, 2012 to conspiracy to commit mail fraud. Randall has not been sentenced yet.

The most recent round of motions in the SCIF RICO case focused on the question about whether a law firm could represent a criminal and his victim. One of the civil defendants, Dr. Lokesh Tantuwaya, M.D., discovered that Hueston Hennigan had represented Randall in one of the criminal cases and possibly a related civil case. Tantuwaya filed the most recent motion for disqualification of the firm.

After considering about a thousand pages of documents and more than four hours of oral argument on this disqualification issue, “the Court confirmed that disqualification was appropriate and necessary here.” The ruling pointed out the following rationale.

“Being a defendant – particularly a criminal one – can be lonely. As a society, we don’t require a defendant’s friends to stand by the defendant. We don’t require a defendant’s parents to stand by the defendant. We don’t require a defendant’s children to stand by the defendant. We don’t even require a defendant’s spouse to stand by the defendant, though that spouse is often someone who took an oath to do so.”

“But a lawyer is different. Representing a client creates an unshakable loyalty that can still persist when bonds of friendship and family fail. There’s a practical reason for this. A lawyer needs to know the worst facts to give clients the best advice. Clients can’t feel comfortable providing such candor unless they know their lawyer is absolutely committed to advancing the clients’ interests and advocating against the conflicting interests of others. Though the rest of the world may be united against them, clients need to know that at least their lawyer will reliably remain in their corner, even in the face of great temptation.”

“The importance and impact of loyalty in the attorney-client relationship extends beyond the client and counsel, to courts too. Judges are often confronted with important issues and difficult disputes. Under our system of law, judges rely on adversarial advocates to help ensure that courts reach the right results in these situations. Adversarial advocacy assumes that lawyers are fiercely loyal in representing their clients. If that loyalty doesn’t exist, the engine of our legal system can’t run. Justice can’t be administered.”

And finally the court made note of the fact that this “disqualification likely caused and will continue to cause grief to lots of people. Of course there’s SCIF and Hueston Hennigan. SCIF is left trying to get its new counsel up to speed on about three years of litigation involving dozens of defendants and opposing attorneys, while Hueston Hennigan must drop a likely lucrative matter from its billing. But there are others too. Randall is left with uncertainty about his legal representation while he has to prepare for a life-altering sentencing hearing. And the Hueston Hennigan attorneys – in particular those in the trenches, who worked passionately on this case for years and who had nothing to do with the representation decisions – have had the rug pulled out from under them, and have had to drop a case they likely lived with for years. Even the civil defendants and their lawyers will have to do some shuffling to deal with the new folks on the other side of the courtroom.”

Hueston Hennigan spokeswoman Lisa Richardson said in a statement quoted by the Los Angeles Business Journal that outside experts have consistently validated the firm’s actions in dealing with the conflict. “After the court’s tentative ruling, State Fund obtained the guidance and opinions of two nationally recognized experts and a former state bar official; each has opined that conflicts were handled well within the ethical rules,” Richardson said. “No experts in this case have opined otherwise.”

WCIRB Submits January 1, 2017 Regulatory Filing

The WCIRB submitted to the California Department of Insurance a January 1, 2017 Regulatory Filing that proposes changes to the Insurance Commissioner’s regulations contained in the California Workers’ Compensation Uniform Statistical Reporting Plan – 1995 (Uniform Statistical Reporting Plan), the California Workers’ Compensation Experience Rating Plan – 1995 (Experience Rating Plan), and the Miscellaneous Regulations for the Recording and Reporting of Data – 1995.

Among the proposed amendments to the Uniform Statistical Rating Plan are changes to the Standard Classification System and to the definition of medical-only claims to specify that all claims, including first aid claims, must be reported to the WCIRB.

The Filing also contains proposed amendments to the Experience Rating Plan including changes to the experience modification worksheet to show the primary threshold and revised tables to include proposed 2017 experience rating values based on the variable split plan that was approved in last year’s Regulatory Filing to be effective January 1, 2017. These proposed experience rating values include primary thresholds by employer size, D-Ratios for each primary threshold and each classification, expected loss rates by classification, and credibility primary and credibility excess values.  

The complete Filing containing all of the WCIRB’s proposed changes and any related documents are available in the Publications and Filings section of the WCIRB website. The WCIRB website will be updated to provide a copy of the Notice of Proposed Action and Notice of Public Comment once it is received from the CDI.

This Filing does not contain proposed changes to the advisory pure premium rates. The WCIRB anticipates submitting the January 1, 2017 Pure Premium Rate Filing this August.

Feds Lose First “Yates Memo” Criminal Trial Against Drugmaker President

Like many before it, this year has been one to watch in government health care fraud enforcement efforts. In September 2015, the Department of Justice (DOJ) released the “Yates Memo,” which reaffirmed the government’s commitment to investigating and prosecuting culpable individuals in cases involving suspected corporate fraud.

While the Yates Memo was not specific to health care companies, the health care industry was anxious to see how the government’s strong re-commitment to holding individuals accountable for corporate wrongdoing would play out given its aggressive pursuit of health care fraudsters. Perhaps the best known test case came when the government announced in October 2015 that it had arrested W. Carl Reichel, the former president of Warner Chilcott, a subsidiary of a pharmaceutical manufacturer. Reichel was indicted and charged with a single count of conspiring to pay kickbacks to physicians in violation of the Anti-Kickback Statute (AKS).

According to the story in the National Law Review, the DOJ announced the Reichel indictment on the same day that it released a statement reporting that the company had agreed to plead guilty to a felony charge of health care fraud. This plea agreement was part of a global settlement under which Warner Chilcott would pay $125 million to resolve criminal and civil liability arising from certain marketing activities. The government held up Reichel’s personal indictment as an example of its commitment to not only holding companies accountable, but also “identif[ying] and charg[ing] corporate officials responsible for the fraud.”

The government’s case did not go as anticipated and last week, given that a federal jury acquitted Reichel.

On October 28, 2015, a grand jury in the U.S. District Court for the District of Massachusetts returned an indictment charging Reichel with a single count of conspiring to pay kickbacks to physicians to induce them to order Warner Chilcott drugs.The alleged kickbacks were in the form of free dinners, “speaker fees” paid for speeches never given, and free food and drinks for physicians’ staff members who filled out prior authorizations for the company’s drugs. The indictment further alleged that Reichel, as the President of Warner Chilcott’s pharmaceuticals division, along with other senior executives, gave sales representatives nearly unlimited expense accounts to take physicians and their spouses out for bi-weekly “medical education programs,” which were in fact just free, expensive dinners with no educational component. Physicians who were especially high orderers were paid speaker fees of $600-$1,200 to speak at these medical educational programs, but, in reality, did not give any clinical lectures.

In return for these dinners and speaking fees, Reichel was alleged to have instructed sales representatives to follow up with the physicians who attended the dinners and ensure that they ordered a sufficient number of Warner Chilcott drugs. Physicians who did not do so were no longer invited to dinners or were terminated as “speakers” until their prescribing habits changed.

For months, the health care industry watched as Reichel battled with DOJ attorneys to gain additional information regarding the facts on which his indictment was based (e.g., the names of his alleged co-conspirators), requested information about plea agreements with potential witnesses against him, attempted to limit the evidence that would be used against him, and challenged the government’s proposed jury instructions as being too vague on the scienter required to prove an AKS violation. On May 23, 2016, the case went to trial and on June 17, 2016 – after two days of deliberations – the jury acquitted Reichel.

During the trial, the government presented evidence that under Reichel’s oversight, Warner Chilcott paid for 200,000 dinner tabs, provided clients with $100 steaks and sailing trips to Rhode Island, and paid $25 million in speaker fees. To make its case, the government relied upon testimony from members of Warner Chilcott’s sales staff, some of whom had entered into plea agreements with the government, expecting lesser sentences in exchange for their testimony against Reichel. Reichel, in turn, argued that the only quid pro quo at issue was the government’s deals with these witnesses, whom his lawyers characterized as admitted felons who ignored company policies.

Based on its verdict, it seems that the jurors may not have been convinced that the dinners and other payments to physicians and their staff were sufficiently tied to past or future prescriptions to constitute an AKS violation. Clearly the government did not meet its burden to prove that Reichel knew that his conduct was illegal. Whatever the reason, the Reichel acquittal may be an early sign that despite the government’s renewed commitment to prosecuting individuals, juries may be setting a higher bar for holding individuals responsible for corporate wrongdoing.

3D Printer Used to Create Replacement Joint Cartilage

Strands of cow cartilage substitute for ink in a 3D bioprinting process that may one day create cartilage patches for worn out joints, according to a team of engineers and their story published in Science Daily. “Our goal is to create tissue that can be used to replace large amounts of worn out tissue or design patches,” said Ibrahim T. Ozbolat, associate professor of engineering science and mechanics at the Pennsylvania State University. He specializes in manufacturing and tissue engineering, with numerous articles published in the context of bioprinting..

Cartilage is a good tissue to target for scale-up bioprinting because it is made up of only one cell type and has no blood vessels within the tissue. It is also a tissue that cannot repair itself. Once cartilage is damaged, it remains damaged.

Previous attempts at growing cartilage began with cells embedded in a hydrogel — a substance composed of polymer chains and about 90 percent water — that is used as a scaffold to grow the tissue.

“Hydrogels don’t allow cells to grow as normal,” said Ozbolat, who is also a member of the Penn State Huck Institutes of the Life Sciences. “The hydrogel confines the cells and doesn’t allow them to communicate as they do in native tissues.”

This leads to tissues that do not have sufficient mechanical integrity. Degradation of the hydrogel also can produce toxic compounds that are detrimental to cell growth.

Ozbolat and his research team developed a method to produce larger scale tissues without using a scaffold. They create a tiny — from 3 to 5 one hundredths of an inch in diameter — tube made of alginate, an algae extract. They inject cartilage cells into the tube and allow them to grow for about a week and adhere to each other. Because cells do not stick to alginate, they can remove the tube and are left with a strand of cartilage. The researchers reported their results in the current issue of Scientific Reports.

The cartilage strand substitutes for ink in the 3D printing process. Using a specially designed prototype nozzle that can hold and feed the cartilage strand, the 3D printer lays down rows of cartilage strands in any pattern the researchers choose. After about half an hour, the cartilage patch self-adheres enough to move to a petri dish. The researchers put the patch in nutrient media to allow it to further integrate into a single piece of tissue. Eventually the strands fully attach and fuse together.

“We can manufacture the strands in any length we want,” said Ozbolat. “Because there is no scaffolding, the process of printing the cartilage is scalable, so the patches can be made bigger as well. We can mimic real articular cartilage by printing strands vertically and then horizontally to mimic the natural architecture.”

The artificial cartilage produced by the team is very similar to native cow cartilage. However, the mechanical properties are inferior to those of natural cartilage, but better than the cartilage that is made using hydrogel scaffolding. Natural cartilage forms with pressure from the joints, and Ozbolat thinks that mechanical pressure on the artificial cartilage will improve the mechanical properties.

If this process is eventually applied to human cartilage, each individual treated would probably have to supply their own source material to avoid tissue rejection. The source could be existing cartilage or stem cells differentiated into cartilage cells.

Employers Fear Proposed Anthem-Cigna Merger

As questions mount over whether health insurer Anthem Inc’s proposed $48 billion purchase of Cigna Corp will win U.S. antitrust approval, an exclusive analysis produced for Reuters suggests the merger could lead to higher costs for large companies offering workplace medical benefits.

More than 154 million people receive health benefits through employers, many of them large national corporations. The large employer market is a top concern for U.S. Department of Justice regulators reviewing the Anthem deal, company officials say. The government could block a deal if it finds evidence it would drive up the cost of such coverage.

Anthem and Cigna, the nation’s No. 2 and No. 5 health insurers, are among a handful of carriers selling national coverage plans to employers with thousands of workers across many states.

Anthem has said the added heft will work for employers, not against them. A bigger Anthem, it emphasizes, could drive better deals from doctors and hospitals and pass savings onto these customers. In addition, Anthem has argued that there still will be plenty of competition: large employers pit smaller, local insurers’ bids against those of large national carriers in regional markets. Anthem officials told an investor conference last month that many employers include health plans from several smaller insurers to cover far-flung employees.

But an Aon Hewitt analysis of benefits data for Reuters found that a majority of large employers buy worker health benefits from just one or two insurers.Among 75 companies representing a cross-section of industries, 54 percent used a single insurer and 26 percent used two. Aon Hewitt, a unit of Aon Plc which helps employers select their benefit plans, based its analysis on data from over 400 customers that participate in healthcare cost research.

Spokeswoman Maurissa Kanter said Aon Hewitt did not conclude “whether or not carrier consolidation would be a competitive issue that could lead to higher prices for employers.” She also said that the data did not “support an argument for or against market consolidation.”

Several human resources directors from large corporations also told Reuters they review potential benefits contracts from only the biggest insurers, rather than regional players. UnitedHealth Group, Anthem, Aetna Inc and Cigna are the only national players in the employer health insurance market.

It is less efficient for companies to hire multiple regional insurers, and the merger could allow the few remaining national insurers to raise their rates, said Peter Carstensen, an antitrust expert and professor emeritus at the University of Wisconsin Law School. “The Aon Hewitt data on its face is bad for the deal and hurts their chances of getting approval,” Carstensen said.

A Justice Department official declined to comment on its review of the deal. It is also considering Aetna’s proposed $34 billion purchase of Humana Inc. If both acquisitions were approved, it would result in an unprecedented consolidation of the top insurers, from five to three.

Anthem has said that buying Cigna would help it drive deeper discounts from hospitals and doctors, holding down the price of medical coverage. “What the Department of Justice will see is that we are going to bring a better focus on managing the cost of care,” Anthem Chief Executive Joseph Swedish told an investor conference last month.

But at least some large U.S. employers fear they will face higher prices if the deal goes through, according to Wall Street analysts. Concerned employers include Detroit automakers, according to a person familiar with the industry’s position.

Other employers found merit in Anthem’s assertion that the deal could benefit customers by eliminating overhead. “There is some chance that consolidation could lower some of those costs,” said Michael D’Ambrose, chief human resources officer for Archer Daniels Midland Co (ADM.N), which buys coverage from Anthem and other Blue Cross Blue Shield plans.

The deal has raised opposition from leading medical groups, California’s insurance commissioner and Democratic lawmakers.
