For years, government and independent analysts have shown that the Centers for Medicare and Medicaid Services (CMS) is overpaying Medicare Advantage (MA) plans–the corporate health plans that cover Medicare benefits–billions of dollars each year. The government’s payment model increases the amount it pays MA plans when they add diagnoses codes to a patient’s profile, regardless of whether they provide more services to the patient. Christopher Rowland reports on incidents of fraudulent billing in Medicare Advantage for the Washington Post.
The problem with “risk-adjusted” capitated payments–fixed monthly payments based on the diagnoses codes in a patient’s chart–is that they incentivize insurers to add irrelevant or even inappropriate diagnoses codes to a patient’s profile in order to get paid more, driving up Medicare spending. In an ideal world, there would be the ability to monitor the problems and correct the overpayments. But, CMS does not begin to have the resources to do so.
Kathy Ormsby worked for the Palo Alto Medical Foundation, a subsidiary of Sutter Health in California, which was looking at patients’ health histories as a way to get doctors to add diagnoses codes to their records. Sutter dismissed Ormsby’s concerns about upcoding. Ormsby found a lot of mistakes, and Sutter had no interest in refunding the government. Medicare Advantage plans appear focused on a ‘dash for cash,” first and foremost.
Ormsby filed a whistleblower lawsuit against Sutter Health because its practice of adding diagnosis codes. The upcoding was not designed to improve patient care, but rather to increase payments for that patient.
Sutter health ended up paying $90 million to the government to settle the lawsuit filed by Ormsby last August. It was a clear case since Ormsby found that nine in ten cancer and stroke diagnoses were false. More than six in ten fracture diagnoses were also false.
Sutter is hardly the only bad actor. Abusive billing practices appear to have become the norm in Medicare Advantage. Many Medicare Advantage plans see no reason not to give patients as many diagnoses as possible in order to increase their revenues. The government does not pay Medicare Advantage plans, or even adjust payments, based on the cost of services they deliver. Medicare Advantage plan incentives are perverse thanks to this payment model, and the proof is in the pudding,
The Justice Department has filed lawsuits against several Medicare Advantage companies for fraudulent billing. Rowland writes: “Justice Department whistleblower allegations and similar lawsuits also are playing out in federal courts against UnitedHealth Group, Cigna and Anthem. The government’s Office of Inspector General has audited Humana and found it overbilled the government. United Healthcare, which is under the umbrella of UnitedHealth Group, and Kaiser Permanente denied any improper conduct. Cigna, Anthem and Humana did not respond to requests for comment.”
Richard Kronick, a health economist, projects that if not stopped, overpayments to Medicare Advantage will amount to more than $600 billion in the next nine years. Putting aside the propriety of Medicare Advantage plan behavior to generate more revenue, what’s clear is that the risk-adjusted capitated payment system is fraught, leaving insurers holding the bag if they attract too many cancer and stroke patients and profiting wildly if they have disproportionate numbers of people who are relatively healthy.
The problem in a nutshell: The government pays Medicare Advantage plans way too much for people who use relatively little care and too little for people who need a lot of care. That payment model needs overhauling. Like large employers, the government should pay health plans a management fee for coordinating care, on top of the cost of covering medically necessary services for their enrollees. Medicare Advantage plans should not profit more the less care they provide.
Rowland spoke with a number of doctors who all confirmed that Medicare Advantage plans are mining data to add codes to patient records. They are expected to add these codes and pressured in various ways to do so.
Kaiser Permanente was giving so many of its patients diagnoses for aortic atherosclerosis that it was overloading its cardiovascular disease management program. Instead of eliminating the diagnosis code and losing revenue, it stopped referring all of these patients to the cardiovascular disease program. Pressure was on to include that diagnosis in patient medical records because it generated an extra $40 million a year for one physician group.
The HHS Office of the Inspector General has issued reports on the cost of upcoding. Donald Berwick and Richard Gilfillan, the former heads of CMS and the Centers for Medicare and Medicaid Innovation, respectively, just published an article in Health Affairs in which they take the available evidence to show that Medicare Advantage not only costs a lot more than traditional Medicare, but it delivers care of questionable quality and promotes health inequities. (Here’s the Just Care post I wrote on topic.)
Berwick and Gilfillan dismiss patient satisfaction with Medicare Advantage as a table rabbit. People choose it to save money, as the upfront costs of Medicare Advantage are less than traditional Medicare; But, out-of-pocket costs in Medicare Advantage are generally much higher than traditional Medicare with supplemental insurance for people with costly health care needs.
