Episode 1: Evaluation and Management Coding | CMS

Today we have a special edition, a podcast from Medicare regarding payment schedule changes



CMS has adopted a more efficient means of communications, reducing paperwork, and increasing efficiency regarding a very complex process in order to obtain reimbursement for services.

This is episode 1 in a continuing series of podcasts from CMS. The entire list of podcasts can be found here.

Dr. Goodrich, what is CMS trying to address with these policies?


TRANSCRIPT

>> Kate Goodrich:  Thanks, Bill.  We're trying to address a number of things, but in particular we're really focusing on reducing regulatory burdens on clinicians.  CMS has heard from physicians and other clinicians for some time now that excessive paperwork and unnecessary regulations, including coding requirements for evaluation and management -- or E&M as we call it -- are detracting from patient care.  The current 1995 and 1997 E&M framework was built on a model of clinical care involving complaint or symptom-based face-to-face encounters between a patient and a clinician.  But, since the 1990s, the nature of clinical care has really changed.  There's a much greater emphasis on patient-centered collaborative models of care with clinical teams that work together to manage chronic conditions.
The current way that clinicians work -- which often requires complex medical decision-making and care coordination.  For example, a primary care doctor who's caring for a Medicare patient with multiple chronic conditions and is coordinating that care between the patient and the multiple specialists helping to care for that patient.  That framework just isn't well-represented in the current E&M codes.  As a result, clinicians find themselves having to perform and document clinical activity that may be of only marginal relevance to the visit but is required in order to receive the level of payment that their effort deserves.
The current system includes five levels for E&M for office visits.  Level one is used primarily by non-physician practitioners, whereas physicians and other clinicians, such as nurse practitioners or physicians' assistants, typically use codes for levels two through five.  There are different documentation requirements for each level.  That's a lot to remember.  Since the significant majority of visits are reported at levels three and four, most visits require documentation of complexity well beyond the minimum.  The policies in this final rule will help to reduce administrative burden by simplifying documentation requirements, and they will improve interoperability so that Medicare providers can operate with greater flexibility and coordination with other providers in order to allow them to keep their focus where it should be, on the patient.
In addition, we are taking new approaches to enhancing the ability of Medicare patients to make use of telecommunications technology for other types of services.
>> Bill Polglase:  Dr. Shah, how do you think these changes will impact your relationships with the patients you see?
>> Anand Shah:  Bill, these final rules restore the vital patient-doctor relationship like giving clinicians and their staff flexibility in documentation for billing purposes and freeing up more time for them to see and care for their patients.  We integrated the extensive input we received from the medical community and other stakeholders, and we look forward to the improvements these phased-in changes will bring in terms of allowing clinicians to spend more time with their patients and enhance the care they provide.
>> Bill Polglase:  Dr. Goodrich, can you give us some specifics that will matter to clinicians?
>> Kate Goodrich:  Absolutely.  First, it's important to note that one of the things that we really tried hard to do in this effort is to listen.  We listened both to practicing clinicians; we also listened to the organizations that represented them.  And while they recognize and appreciate our burden-reduction efforts, they did urge us to take more time before implementing significant payment changes.  They also identified several concerns about various aspects of our proposals.
So, we listened to all of these concerns, and we finalized policies that will be implemented over several years.  Starting in January of 2019, we will be reducing burden to provide some immediate relief for doctors and other clinicians.  These include removing redundancy in the E&M documentation.  So, for example, we'll no longer require clinicians to re-enter certain information into the medical record that was already entered by support staff, or even by Medicare patients themselves.  CMS also will reduce unnecessary physician supervision of radiologist assistants for diagnostic tests.  And we are removing burdensome and overly-complex functional status reporting requirements for outpatient therapy.
We're also finalizing other documentation, coding, and payment policies for 2021 instead of 2019 in order to give stakeholders more time to prepare.  And we're also making important changes to the proposed policies based upon the comments we received.
>> Bill Polglase:  I know some of the evaluation and management documentation guidelines have been in place since 1995, and updated guidelines issued in 1997.  Dr. Shah, are they being updated now?
>> Anand Shah:  Bill, we're actually giving physicians a choice in how to document E&M office visits as we proposed.  Physicians will be able to use medical decision-making or time instead of applying the current 1995 or 1997 E&M documentation guidelines, or, alternatively, they could continue using the current framework.  I should also add that we're simplifying payments by establishing a single payment rate for E&M levels two through four office visits with one rate for new patients and another rate for established patients.  Related to this, we're requiring that physicians will only need to meet documentation requirements associated with level two visits when performing these office visits, except when time defines a service.  Clinicians can document additional information in the chart for clinical and other purposes.  Again, most of the hundreds of millions of Medicare visits are billed at levels three and four.  So, this will result in a significant burden reduction for the majority of visits.
>> Bill Polglase:  And I know that based on comments received, we are keeping payments for level five E&M office visits separate in order to better account for the care and needs of particularly complex patients.  Dr. Goodrich, can you talk a little bit more about this?
>> Kate Goodrich:  Yes, I'd be happy to.  We are finalizing additional adjustments that account for extended visits, as well as for the complexities of primary care and specialty care that is non-procedure based.  In fact, in response to comments, we broadened the definition of the non-procedural specialty care.  And we designed these add-on payments so that for most clinicians, additional documentation will not be necessary in order to report the codes.  That's something many commenters raised concerns about, and we are committed to making that work.
After considering concerns raised by commenters in response to the proposed rule, we are not finalizing other aspects of our proposal such as reduced payment when E&M office visits are furnished on the same day as procedures or separate podiatry E&M visit codes.  We'll also continue to work with the clinician community to make sure that we get it right.  We want clinicians to be fairly compensated for taking care of Medicare patients, and in particularly the most complex patients.
>> Anand Shah:  And I would also like to note that in addition to reducing burden, this final rule makes a real effort at improving access to care.  We're modernizing the Medicare benefit to improve access to care with coverage for new tele-health benefits and, also, new options for virtual.  It's not easy for people to get to their healthcare provider, whether they live in urban or rural communities.  This is a way to get more accessible care and will create more opportunities for patients to connect with providers by leveraging the latest advances in technology.
>> Bill Polglase:  How do you think this will impact how you, as physicians, deliver care?
>> Kate Goodrich:  So, when I take care of Medicare patients, I'll be separately paid for interactions to assess whether or not a face-to-face visit is needed.  So, if I do a brief phone call or a Skype call, or I review a picture that a patient texts me, I can submit a claim for that.  Same goes for consultations with other professionals and remote physiologic monitoring that are currently bundled together.
>> Anand Shah:  I should add we're also continuing to expand the list of services that clinicians can provide through tele-health, including prolonged preventive services that account for additional time when services like the welcome to Medicare preventive visit or the annual wellness visit are furnished.
>> Bill Polglase:  Very interesting and impactful stuff.  Dr. Goodrich and Dr. Shah, thanks for making the time to speak with me about these important policy changes, and thanks to you in our audience for listening.  For the CMS Beyond the Policy podcast, I'm Bill Polglase.
You can subscribe to this podcast through iTunes or whatever podcast service you use.  We'll be back soon with another edition of CMS Beyond the Policy.  This podcast is brought to you by the U.S. Department of Health and Human Services.

Why getting enough sleep reduces cardiovascular disease risk: Sleep-modulating hormone hypocretin found to also control production of inflammatory cells

Getting enough sleep is key to good health, and studies have shown that insufficient sleep increases the risk of serious problems, including cardiovascular disease. Now investigators have discovered one way that sleep protects against the development of atherosclerosis.

Images of plaque from the artery of a mouse model of atherosclerosis that experienced a normal sleeping pattern (left) and an image of arterial plaque from a mouse model that underwent sleep fragmentation (right). The amount of arterial plaque in the sleep-fragmented mouse is significantly larger.


Massachusetts General Hospital (MGH) investigators have discovered one way that sleep protects against the buildup of arterial plaques called atherosclerosis. In their paper receiving advance online publication in Nature, they describe the mechanism by which insufficient sleep increases production of inflammatory white blood cells known to be major contributors to atherosclerosis.
"We have discovered that sleep helps to regulate the production in the bone marrow of inflammatory cells and the health of blood vessels and that, conversely, sleep disruption breaks down control of inflammatory cell production, leading to more inflammation and more heart disease," says Filip Swirski, PhD, of the MGH Center for Systems Biology, senior author of the Nature paper. "We also have identified how a hormone in the brain known to control wakefulness controls processes in the bone marrow and protects against cardiovascular disease."
To investigate how insufficient sleep increases atherosclerosis, Swirski's team subjected mice genetically programmed to develop atheroslcerosis to repeated interruptions of their sleep, similar to the experience of someone constantly waking up because of noise or discomfort. While there were no changes in weight, cholesterol levels or glucose tolerance in the sleep-deprived mice, compared to animals from the same strain allowed to sleep normally, those subjected to sleep fragmentation developed larger arterial plaques and had higher levels of monocytes and neutrophils -- inflammatory cells that contribute to atherosclerosis -- in their blood vessels.
Further experiments revealed that the sleep-deprived mice had a nearly two-fold increase in the production in their bone marrow of stem cells that give rise to white blood cells. A hormone called hypocretin, produced in the brain structure called the hypothalamus and known to have a role in the regulation of sleep, was found to play an unexpected role in controlling white blood cell production. While normally produced at high levels when animals -- including humans -- are awake, hypocretin levels were significantly reduced in the sleep-deprived mice.
The MGH team found that hypocretin regulates production of white blood cells through interaction with neutrophil progenitors in the bone marrow. Neutrophils, they discovered, induce monocyte production through release of a factor called CSF-1, and experiments with mice lacking the gene for hypocretin revealed that the hormone controls CSF-1 expression, monocyte production and the development of arterial plaques. In sleep-deprived animals, the drop in hypocretin led to increased CSF-1 production by neutrophils, elevated monocyte production and accelerated atherosclerosis.
"This is a direct demonstration that hypocretin is also an important inflammatory mediator," says Swirski, an associate professor of Radiology at Harvard Medical School. "We now need to study this pathway in humans, explore additional mechanisms by which proper sleep maintains vascular health and further explore this newly identified neuro-immune axis."

No, Zeke, You’re Not Paying For My Medicine | Galen Institute

THIS POST WAS ORIGINALLY POSTED NOVEMBER 2015

Zeke Emanuel is tired of paying for your expensive medicine.
Dr. Emanuel, who served in a senior position at the Office of Management and Budget where he contributed to the recurring nightmare known as ObamaCare, recently complained in the New York Times [“I Am Paying For Your Expensive Medicine”] that his insurance rates are high because the medicines you’re taking cost too much.
“We all need to care about not only our own health care bills but also those of our neighbors,” he writes.  And by caring about your neighbors’ bills, he means finding a way to avoid them.
What evidently provoked Dr. Emanuel to fret about your medical bills was something called a PCSK9 inhibitor, a recently approved class of biologics that, according to a preliminary study, reduces the risk of heart disease and stroke by half.
YOU may not know it, but you could be on the hook to pay at least $124 this year for a drug you probably don’t take.
The drug is a new class of cholesterol-lowering agents called PCSK9 inhibitors. Its cost and how we are paying for it illustrate why we all need to care about not only our own health care bills but also those of our neighbors. And it helps focus the debate about drug prices on two questions: What is the value delivered by the drug, and can that be linked to its price? And how should such value-based prices be implemented?

In July, the Food and Drug Administration approved the first of two new PCSK9 inhibitors that lower the bad type of cholesterol, LDL. Studies suggest that they can reduce it by up to 60 percent, compared with a placebo, and reduce it up to 36 percent more than statins and a drug called ezetimibe. However, there are no definitive data on how much these drugs actually reduce heart attacks, strokes and deaths from heart disease. 

Ethical concerns aside (should government determine how much an additional quality-year” of life (QUALY) is worth?), government policies have so distorted medical prices as to render the sorts of calculations Emanuel favors suspect.  Before considering whether to import England’s algorithm for determining value, policymakers would do well to reflect on the wreckage that previous government forays into the health care marketplace have wrought.
The government, for example, imposes price controls in the VA system.  It also operates aMedicaid “rebate” program, which requires drug makers to mark down the price of medicines in that burgeoning program.  It mandates similar price concessions to a growing list of clinics and hospitals.  Manufacturers also must slash prices by 50 percent for Medicare beneficiaries who have fallen into the drug benefit’s “donut hole.”
When the government requires manufacturers to provide steep discounts to such a broad swath of the market, they predictably charge higher prices to everyone else.
Emanuel doesn’t just overlook the distorting effect government actions have had on drug prices, but he also fails to see how government has deformed health insurance markets.  Federal programs have long divorced premiums from risk.  ObamaCare has extended that practice into the individual and small group markets, creating a program in which people who wait until they are sick to buy insurance pay the same rates as those who maintained continuous coverage when they were healthy.
It has thus made insurance a good deal for people who have pre-existing medical conditions and a bad deal for people who don’t.   That is a major reason why the vast majority of uninsured people in reasonably good health who don’t qualify for government premium and cost-sharing subsidies have so far chosen to remain uninsured.  It also helps explain how insurance companies have managed to lose money under the program, even after pocketing billions in corporate welfare payments.
The accretion of government intrusions into the health care marketplace has distorted medical prices beyond recognition.  Good intentions have motivated every intervention, each of which has engendered a new round of problems that, in turn, have inspired further well-meaning interventions.  The result is a costly and inefficient system where prices are unhinged from value.
Government is bad at paying for value.  For consumers, it is a core competency.  Instead of smoldering over other people’s medical bills, Emanuel would do well to devote his considerable intellect to scraping away regulatory barnacles that prevent price discovery.  Instead of more government, we need a health care system that functions like the rest of the economy where, as Emanuel put it, “individuals determine value.”
Doug Badger is a retired White House and U.S. Senate policy adviser and a Senior Fellow at the Galen Institute.

Health chatbot:

Medical chatbots could help doctors but won't replace them

  • Sutter Health and Ada Health are teaming up for a new symptom-checking chatbot, which will roll out next week.
  • I got an early look.
  • Here's how it went.
Chatbots that analyze users' symptoms and offer advice are all the rage in Silicon Valley.
But I had never actually used one -- until Northern California-based hospital chain Sutter Health gave me early access to a new service they've developed with Ada Health, a European tech company that is bringing its symptom-checking software to the United States.

About four million people have downloaded and used Ada's app, according to its website. But in a few weeks, a version of its symptom-checking software will also be available for folks to use for free via Sutter Health's website, without needing to sign up via the app.
As luck would have it -- or rather, bad luck -- I recently had a bout of what seemed like food poisoning to put it to the test.
Here's how it went:
I signed up with my first name, date of birth and some basic health information, like whether I'm a smoker. At that point, I started typing in my symptoms, primarily nausea and vomiting, as well as how long I'd had them. It wasn't particularly serious, so I noted that it cleared up in less than a day.


From there, Ada led me through a series of questions to find out more about how I was feeling. I noted that I didn't feel any abdominal bloating, dizziness, or cramping, among other symptoms. All in all, it took me about ten minutes to get through all of the prompts.
That led me to a web page that listed a breakdown of plausible explanations for my ailment. The most likely was viral gastroenteritis, which is a condition that I'm told I could manage from home. But some of the others, such as irritable bowel syndrome, came with a recommendation that I see a doctor. I was planning to stay at home and I was inclined to believe the most obvious explanation, so this gave me a little extra reassurance.
Had the chatbot sent me down the right path?
I called up Sutter Health's chief of digital patient experience Albert Chan, to get his perspective on whether he agrees with the assessment, why he chose to work with Ada Health, and what he thinks these sort of medical AI tools will be used for in the coming years.

Smarter over time

Chan believes there's a gap in the market for technologies that can help patients figure out what to do when they get sick, which led him to reach out to Ada Health about a partnership. As Chan points out, it's not always obvious for most people whether to stay home to rest and recover, see a primary care doctor or go straight to the emergency room.
"We want them to get the appropriate level of care," said Chan.
Chan is also a doctor, so I briefly ran him through my symptoms and he felt that the AI had advised me well. I noted that three of the five potential diagnoses indicated that I should seek medical care, while the most likely (viral gastroenteritis) suggested that I could stay home.
Chan said these tools are meant to be "advisory," rather than a replacement for a doctor or a formal diagnosis. If I got any worse, he said, I should consider seeing a doctor.
I called up Ada Health's chief commercial officer Jeff Cutler, who noted that the tool is designed to learn about its users over time.
"It really depends on the person, as some might take action based on the most severe decision while others are reassured by the most likely one," he said. That's why Ada lists a range of possible explanations to help patients make their choice.
Cutler said that if I were using the Ada app, these recommendations would get more accurate as Ada learned more about me. (The Sutter Health version on the website is anonymous, but I can save the assessment and download the app from there.)

Chatbots won't replace doctors, but could help them

While it's sexy to imagine that an AI will replace doctors -- and many in Silicon Valley do find that vision enticing -- that's not going to happen anytime soon. There are so many technological and regulatory limitations before an AI can diagnose disease.
In my case, I sort of knew what I wanted to do: I was feeling OK and didn't want the hassle of going to a clinic, so I took Ada's least-frightening suggestion to heart. But I could imagine someone else in my shoes wanting to play it safe and booking an appointment regardless. Technology can help be a guide, but personal health decisions are often subjective based on the patient's personality, family history and a range of other factors.
But here's where I do think tools like Ada could prove useful:
  • More honesty: Sometimes it's less awkward to share embarrassing symptoms with a chatbot, which might mean patients are more upfront. At one point, Ada asked me if I had experienced any anal discharge, a question that would have prompted a nervous giggle if a doctor had been asking.
  • Informing patients: In Chan's view, doctors can use these tools to make the most of their time with a patient, as the most obvious questions will get asked upfront. "When they (the patient) gets to the doctor's office, they've both already thought about it and have a leg up."
  • Replacing tools like WebMD: Many of the websites and apps that people use today for symptom-checking are far dumber, and will often lead the patient to believe they have something deadly like cancer, when their actual diagnosis is fairly minor. Tools like Ada are clearly a step up from that.
  • Better navigation, in some cases: Over time, technologies like these will get smarter about directing the patient to the right place, even if they do typically recommending medical care over staying home in cases where it's not clear either way.
Sutter's integration with Ada goes later this month. If you have a chance to use it, let me know what you think @chrissyfarr on Twitter.

Email fraud in healthcare up 473% — 6 things to know




With the rising cybersecurity vulnerability, most have forgotten email vulnerability.
Hospitals and health systems received an influx of fraudulent emails last year , a persistent problem that has cost healthcare organizations $12.5 billion since the end of 2013, a Proofpoint study found.
Cybersecurity provider Proofpoint analyzed more than 160 billion emails sent across 150 countries in 2017 and 2018 to identify the prevalence of email fraud at 450 healthcare organizations.
Six things to know:
1. In the fourth quarter of 2018, healthcare organizations were the targets of 96 email fraud attacks, a 473 percent increase compared to the first quarter of 2017.
2. The most common type of email fraud in 2018 was wire-transfer .
3. For the average targeted organization, 65 staff members were attacked in the fourth quarter of 2018. The email fraud attacks were most likely to occur on weekdays between 7 a.m. and 1 p.m.
4. The majority of healthcare organizations — 95 percent — were targeted through their own trusted domains, which were spoofed to target patients and fellow business partners.
5. Of all the emails sent from healthcare-owned organizations, 45 percent in the fourth quarter of 2018 appeared suspicious. The suspicious emails were most often sent to employees (65 percent), followed by patients (42 percent) and business partners (15 percent).
6. Proofpoint suggests that healthcare organizations adopt the following to protect themselves from email fraud:
• Email authentication
• Machine learning and policy enforcement
• Domain monitoring

Healthcare is this Year’s Political Football from the Association of American Physicians and Surgeons



Healthcare is the political football of the midterm elections. But unlike the game of football, there are no rules. And the goal is to win – not for the benefit of the team (the voters) but to gain status and power. Politicians are looking for a sound bite that catapults them into the spotlight. Spartacus was a dud. People like free stuff. Let’s try Medicare-for-All! Of course, the ads won’t mention that taxes will be doubled and private health insurance is essentially outlawed.
Currently, eight bills proposing variations of federally sponsored healthcare are on the horizon. If one bill fails, another one is in the queue. The government’s attempts to improve our “healthcare system” by top-down control of doctors and their patients have failed. For example, electronic medical records meant to streamline and make medicine more efficient have done the opposite: they are costly, non-interoperable and waste 50 percent of doctors’ time.
Insurers exited the ACA marketplace – decreasing choice and competition. Lower insurance premiums were a pipe dream, while the profits of pharmaceutical companies and insurers soared. Many people were unable to afford insurance and certainly could not “keep [their] doctor” whom they liked.
Not only is it prohibitively expensive, but central control will bring use of more government guidelines, some of which have proven to not be in patients’ best interest. For example, in contrast to private medical organizations, the U.S. Preventive Services Task Force recommends biennial mammograms for those over 50 years. Yet the incidence rates for invasive breast cancer in women under age 50 has increased since the mid-1990s and breast cancer is more common in African-American women than white women in the under-45 age group.
Likely ignited by the limited choices on ACA exchanges, the personalized medical care movement was gaining steam. Accordingly, the Trump Administration made increasing healthcare freedom a key priority. A year ago, President Trump released an executive order “Promoting Healthcare Choice and Competition across the United States.”

How Virtual Reality Will Transform Medicine -


If you still think of virtual reality as the province of dystopian science fiction and geeky gamers, you had better think again. Faster than you can say “Ready Player One,” VR is starting to transform our world, and medicine may well be the first sector where the impact is profound. Behavioral neuroscientist Walter Greenleaf of Stanford University has been watching this field develop since the days when VR headsets cost $75,000 and were so heavy, he remembers counterbalancing them with a brick. Today some weigh about a pound and cost less than $200. Gaming and entertainment are driving current sales, but Greenleaf predicts that “the deepest and most significant market will be in clinical care and in improving health and wellness.”

By the mid-1990s research had shown it could distract patients from painful medical procedures and ease anxiety disorders. One initial success was SnowWorld, which immersed burn patients in a cool, frozen landscape where they could lob snowballs at cartoon penguins and snowmen, temporarily blocking out the real world where nurses were scrubbing wounds, stretching scar tissue and gingerly changing dressings. A 2011 study with 54 children in burn units found an up to 44 percent reduction in pain during VR sessions—with the bonus that these injured kids said they had “fun.”  In a compelling 2017 paper that reviews 25 years of work, Rizzo and co-author Sebastian Koenig ask whether clinical VR is finally “ready for primetime.” If today's larger studies bear out previous findings, the answer seems to be an obvious “yes.”
Greenleaf counts at least 20 clinical arenas, ranging from surgical training to stroke rehabilitation to substance abuse where VR is being applied. It can, for example, help recovering addicts avoid relapses by practicing “refusal skills”—turning down drinks at a virtual bar or heroin at a virtual party. Brain imaging suggests that such scenes can evoke very real cravings, just as Bravemind can evoke the heart-racing panic of a PTSD episode. Researchers foresee a day when VR will help make mental health care cheaper and more accessible, including in rural areas.
Until recently, large-scale studies of VR have been missing in action. This is changing fast with the advent of cheaper, portable systems. Difede, Rizzo and three others just completed a randomized controlled trial with nearly 200 PTSD patients. Expected to be published this year, it may shed light on which patients do best with this high-tech therapy and which do not. In a study with her colleague, burn surgeon Abraham Houng, Difede is aiming to quantify the pain-distraction effects of a successor to SnowWorld called Bear Blast, a charming VR game in which patients toss balls at giggly cartoon bears. They will measure whether burn patients need lower doses of intravenous painkillers while playing.

Another success came in the wake of 9/11. Psychologist JoAnn Difede of NewYork-Presbyterian/Weill Cornell Medical Center began using VR with World Trade Center survivors suffering from post-traumatic stress disorder (PTSD) and later with soldiers returning from Afghanistan and Iraq.
In Difede's laboratory, I saw the original 9/11 VR program with its scenes of lower Manhattan and the newer Bravemind system, which depicts Iraqi and Afghan locales. Developed with Department of Defense funding by Albert “Skip” Rizzo and Arno Hartholt, both at the University of Southern California, Bravemind is used to treat PTSD at about 100 U.S. sites. The approach is based on exposure therapy, in which patients mentally revisit the source of their trauma guided by a therapist who helps them form a more coherent, less intrusive memory. In VR, patients do not merely reimagine the scene, they are immersed in it.
As clinicians familiarize themselves with VR and construct suitable environments for patients we begin to approach the Star Trek fantasy "Holodeck".  What is next?

Robot wars, Competition is heating up

Are surgical robots better than surgeons ? Well first of all surgical robots are not autonomous. They require a surgeon to operate them. Gallbladder, prostate, abdominal, knee and back surgery are some of the beneficiaries of the new technology.  The primary impetus for the development of a small incision is lower risk of bleeding, infection, and a much shorter post operative recovery process. The length of inactivity diminishes by weeks.





Robot wars: $60B Intuitive Surgical dominated its market for 20 years. Now rivals are moving in



It was the femoral artery of a rat that piqued the curiosity of Gary Guthart. Then a new hire at a research institute spun from ­Stanford University, he was assigned to a surgical robotics lab. He was asked to sew a severed artery back together by hand, and then to try it again with a prototype robot.
“That’s what people have to do in surgery?” Guthart recalls thinking. “That looks like both a really interesting, important problem and a really hard ­problem, and that got me really excited.” 

Three years later, in 1996, Guthart was working at a startup called Intuitive Surgical, which had licensed technology from the institute, SRI International. Intuitive launched a robotic surgical helper, branded da Vinci, in 1998. The da Vinci would go on to change surgery in the same way the iPhone has transformed cellphone use.




Today, nearly 5,000 da Vincis are in operating rooms, used in one million surgeries per year. Intuitive went public just after the tech bubble peaked in 2000, and still the stock ended the dec­ade 17 times higher than at its IPO. Why? Because, until now, Intuitive has had the business to itself. The price tag on a da Vinci is about $1.5 million. Plus, it sells about $1,900 in replacement parts per operation. The company’s 30% net profit margin eclipses Microsoft’s.



But Intuitive might not be alone in the operating room much longer. Read more from Michela Tindera on Forbes


Speaking of robotic surgery, Johnson & Johnson announced Wednesday that it plans to spend over $5 billion to boost its robotics program, buying startup Auris Health for about $3.4 billion in cash, plus additional milestone payments of up to $2.35 billion.

Guthart, 53, has been chief executive since 2010 and is sitting on $315 million worth of Intuitive stock and options based on February 13 closing prices. But now he’s going to have to work a little harder. Medtronic, a medical-device maker with sales eight times Intuitive’s, and Verb Surgical, a partnership between Johnson & Johnson and Alphabet, are expected to enter the surgery robot market in the next year. They’re likely to compete on price. And these heavyweights are also making inroads into Intuitive's future markets: J&J announced Wednesday that it would pay $3.4 billion in cash for Auris Health, a rival robotics startup with a device to perform lung biopsies.
