Ever for the reason that high-profile homicide of UnitedHealthcare CEO Brian Thompson final 12 months, well being insurers have confronted heavy scrutiny and heightened resentment from the general public. Now a new examine may fan these flames. That’s as a result of it discovered that differential coding patterns between Medicare Benefit (MA) and Conventional Medicare (TM) plans led to MA plans receiving an estimated $33 billion in additional income—with $13.9 billion, or 42% of the whole, going into the coffers of UnitedHealth Group.
These findings, from the 12 months 2021, add particular context to previous analysis that discovered proof of Medicare Benefit plans having the next diagnostic “coding intensity” than conventional Medicare, which means they document extra well being situation diagnoses than conventional Medicare for comparable beneficiaries. Due to that, Congress’s Medicare Cost Advisory Fee had estimated, Medicare spends 13% extra for MA enrollees than it will in the event that they have been enrolled in conventional Medicare—with that distinction accounting for $50 billion in MA overpayments in 2024.
Medicare Benefit plans, in line with the brand new findings, are paid extra for sicker members and fewer for more healthy members, which supplies an incentive for MA plans to report as many diagnoses as legitimately potential. However no analysis till now, say the authors, has estimated the quantity of additional income every insurer receives.
“The most important takeaway is that some Medicare Advantage insurers code much more aggressively than other insurers, and receive many billions of dollars in additional payment as a result,” the examine writer, Richard Kronick, professor of household drugs on the Herbert Wertheim Faculty of Public Well being, College of California San Diego. “As a result, much of what determines which insurers are successful in Medicare Advantage is not whether the insurer is providing high quality care and doing so efficiently, but simply how aggressive it is in coding.” He factors to the extra $13.9 billion raised by UnitedHealth Group, which breaks all the way down to $1,863 per beneficiary, in comparison with $0.5 billion, or $278 per beneficiary, for Kaiser.
A spokesperson for the UnitedHealth Group declined to remark to Fortune on the findings, as a substitute referring our publication to the nonprofit Higher Medicare Alliance, which counts Wyatt Decker, a United Well being Group chief doctor, as a board member.
“This is a flawed apples-to-oranges analysis,” Kaitlyn Saal-Ridpath, Vice President of Policy and Research at Better Medicare Alliance, tells Fortune. “It overlooks known under-coding in Fee-For-Service Medicare and does not adjust for clinical or demographic differences between Medicare Advantage and Fee-for-Service Medicare beneficiaries, an essential step for fair comparison. Meanwhile, the underlying data is outdated and does not reflect recent risk-adjustment changes. We welcome serious analyses to help drive policy conversations around Medicare Advantage, but this study misses the mark.”
However, Kronick says, “No analysis is perfect, but we have done a careful job of measuring the differences in coding patterns between Medicare Advantage and Traditional Medicare, and, even more importantly, the very large differences between insurers in coding patterns… We have, I think, conclusively shown that some insurers code much more aggressively than others, and receive many billions of dollars in additional revenue as a result.”
Greater than half (54%) of eligible Medicare beneficiaries have been enrolled in Medicare Benefit in 2024, in line with KFF, accounting for $462 billion of whole federal Medicare spending. Additional, the enrollment in MA is very concentrated amongst a handful of corporations, with UnitedHealthcare and Humana accounting for practically half (47%) of all MA enrollees nationwide.
Recently, there was a shift in direction of MA. Whereas normally, after age 65, you’ve two Medicare choices—conventional Medicare (Components A, B, and D, and infrequently a Medigap plan) or a personal well being insurer’s Medicare Benefit plan, additionally known as Half C, individuals with retiree well being advantages from their former employers are sometimes not given a selection. As an alternative, they’re being advised they need to enroll in a Medicare Benefit plan, with its restricted community of docs and hospitals, or lose their retiree well being advantages altogether.
On the similar time, latest analysis reveals that MA enrollees are distinctly more healthy—possible as a result of individuals who want extra well being care are much less keen to just accept the restrictions (resembling prior authorization and restricted networks) that MA plans impose.
How the researchers got here to their findings about Medicare
For the examine, the researchers analyzed danger scores—numbers which characterize the expected value of treating a particular affected person or group of sufferers in comparison with the typical Medicare affected person, primarily based on sure well being situations. In addition they analyzed the consequences of “persistence” and “new incidence” on danger scores over 24 months, with persistence outlined as the proportion of members coded with a prognosis in 12 months one which endured in 12 months two, and new incidence referring to the proportion of members with a brand new prognosis in 12 months two.
What they discovered was that the typical MA danger rating (1.26) was 18.5% larger than the typical TM danger rating (1.07).
Persistence and new incidence charges assorted throughout insurers, the researchers discovered, with UnitedHealth Group’s common 2021 danger rating .28 larger—considerably bigger than the MA business common of .19—than it will have been if persistence and new incidence had been at TM ranges.
The findings spell hassle, says Dr. J. Michael McWilliams of the Harvard Medical Faculty and Brigham and Girls’s Hospital, who responded to the examine in an accompanying editorial, additionally printed Monday within the Annals of Inner Medication.
“The manipulability of the risk adjustment system in Medicare Advantage (MA) is a massive problem,” he writes.
“It is well documented that the system’s reliance on diagnosis codes that insurers can influence for gain is responsible for tens of billions of dollars in payments to MA plans above what would be spent in traditional Medicare (TM), adding to Medicare’s fiscal challenges,” he continues. “But the problem runs deeper, as the incentives to code diagnoses more intensely also distort competition and resource allocation within MA.”
Among the many many points the researchers have uncovered, McWilliams continues, is that, as a result of the better-coding insurers are typically bigger, “local markets could become even more highly concentrated, further limiting the pressure insurers feel to share their subsidies and savings with enrollees as better coverage.”
However fixing the issue, he notes, would have a catch.
“The catch is that the resulting payment cuts would mean higher premiums or less generous benefits for enrollees,” McWilliams writes.
As a result of whereas Medicare Benefit insurers preserve a considerable portion of their subsidies and financial savings as income, they do cross alongside a large share to enrollees. “As subsidies have grown more generous, MA has served as a backdoor financing mechanism to address coverage gaps that have long limited the value of TM (for example, its lack of an out-of-pocket maximum),” he explains, including that enrollees in MA profit from considerably decrease out-of-pocket prices.
In order fee subsidies are reversed by danger adjustment reform and different proposed measures, he factors out, “the lost benefits for enrollees could be significant. To the extent it is socially desirable to provide seniors with better coverage than the traditional benefit, policymakers must grapple with this tradeoff.”
