The Center for Medicare and Medicaid Innovation (CMMI, or “the Innovation Center”) recently announced an initiative called Comprehensive Primary Care Plus (CPC+). It evolved from the Comprehensive Primary Care (CPC) initiative, which began in 2012 and runs through the end of this year. Both initiatives are designed to promote and support primary care physicians in organizing their practices to deliver comprehensive primary care services. Comprehensive Primary Care Plus has some very promising components, but also misses some compelling opportunities to further advance payment for primary care services.

The earlier initiative, CPC, paid qualified primary care practices a monthly fee per Medicare beneficiary to support practices in making changes in the way they deliver care, centered on five comprehensive primary care functions: (1) access and continuity; (2) care management; (3) comprehensiveness and coordination; (4) patient and caregiver engagement; and, (5) planned care and population health. For all other care, regular fee-for-service (FFS) payment continued. The initiative was limited to seven regions where CMMI could reach agreements with key private insurers and the Medicaid program to pursue a parallel approach. The evaluation funded by CMMI found quality improvements and expenditure reductions, but savings did not cover the extra payments to practices.

Comprehensive Primary Care Plus uses the same strategy of conducting the experiment in regions where key payers are pursuing parallel efforts. In these regions, qualifying primary care practices can choose one of two tracks. Track 1 is very similar to CPC. The monthly care management fee per beneficiary remains the same, but an extra $2.50 is paid in advance, subject to refund to the government if a practice does not meet quality and utilization performance thresholds.

The Promise Of CPC+

Track 2, the more interesting part of the initiative, is for practices that are already capable of carrying out the primary care functions and are ready to increase their comprehensiveness. In addition to a higher monthly care management fee ($28), practices receive Comprehensive Primary Care Payments. These include a portion of the expected reimbursements for Evaluation and Management services, paid in advance, and reduced regular fee-for-service payments. Track 2 also includes larger rewards than does Track 1 for meeting performance thresholds.

The combination of larger per beneficiary monthly payments and lower payments for services is the most important part of the initiative. By blending capitation (monthly payments not tied to service volume) and FFS, this approach might achieve the best of both worlds.

Even when FFS payment rates are calibrated correctly (discussed below), the rates are pegged to the average costs across practices. But since a large part of practice cost is fixed, it means that the marginal cost of providing additional services is lower than the average cost, leading to incentives to increase volume under FFS. The lower payments reduce or eliminate these incentives. Fixed costs, which must also be covered, are addressed through the Comprehensive Primary Care Payments. By involving multiple payers, practices are put in a better position to pursue these changes.

An advantage of any program that increases payments to primary care practices is that it can partially compensate for a flaw in the relative value scale behind the Medicare physician fee schedule. This flaw leads to underpayment for primary care services. Although the initial relative value scale implemented in 1992 led to substantial redistribution in favor of evaluation and management services and to physicians who provide the bulk of them, a flawed update process has eroded these gains over the years to a substantial degree.

In response to legislation, the Centers for Medicare and Medicaid Services are working correct these problems, but progress is likely to come slowly. Higher payments for primary care practices through the CPC+ can help slow the degree to which physicians are leaving primary care until more fundamental fixes are made to the fee schedule. Indeed, years of interviews with private insurance executives have convinced us that concern about loss of the primary care physician workforce has been a key motivation for offering higher payment to primary care physicians in practices certified as patient centered medical homes.

Two Downsides

But there are two downsides to the CPC+.

One concerns the lack of incentives for primary care physicians to take steps to reduce costs for services beyond those delivered by their practices. These include referring their patients to efficient specialists and hospitals, as well as limiting hospital admissions. There are rewards in CPC+ for lower overall utilization by attributed beneficiaries and higher quality, but they are very small.

We had hoped that CMMI might have been inspired by the promising initiatives of CareFirst Blue Cross Blue Shield and the Arkansas Health Care Improvement initiative, which includes the Arkansas Medicaid program and Arkansas Blue Cross Blue Shield. Under those programs, primary care physicians are offered substantial bonuses for keeping spending for all services under trend for their panel of patients; there is no downside risk, which is understandable given the small percentage of spending accounted for by primary care. The private and public payers also support the primary care practices with care managers and with data on all of the services used by their patients and on the efficiency of providers they might refer to. These programs appear to be popular with physicians and have had promising early results.

The second downside concerns the inability of physicians participating in CPC+ to participate in accountable care organizations (ACOs). One of CMMI’s challenges in pursuing a wide variety of payment innovations is apportioning responsibility across the programs for beneficiaries who are attributed to multiple payment reforms. As an example, if a beneficiary attributed to an ACO has a knee replacement under one of Medicare’s a bundled payment initiatives, to avoid overpayment of shared savings, gains or losses are credited to the providers involved in the bundled payment and not to the ACO. As a result, ACOs are no longer rewarded for using certain tools to address overall spending, such as steering attributed beneficiaries to efficient providers for an episode of care or encouraging primary care physicians to increase the comprehensiveness of the care they deliver.

Keeping the physician participants in CPC+ out of ACOs altogether seems to be another step to undermine the potential of ACOs in favor of other payment approaches. This is not wise. The Innovation Center has appropriately not established a priority ranking for its various initiatives, but some of its actions have implicitly put ACOs at the bottom of the rankings. Recently, Mostashari, Kocher, and McClellan proposed addressing this issue by adding a CPC+ACO option to this initiative.

In an update to its FAQ published May 27, 2016 (after out blog was put into final form), CMMI eased its restriction somewhat by allowing up to 1,500 of the 5000 practices expected to participate in CPC+ to also participate in Medicare Shared Savings Program (MSSP) ACOs. But the prohibition continues to apply to Next Gen ACOs, the model that has created the most enthusiasm in the field. If demand for these positions in MSSP ACOs exceeds 1,500, a lottery will be held. This change is welcome but does not really address the issue of disadvantaging ACOs in situations where a beneficiary is attributed to two or more payment reform models. CMMI is sending a signal that CPC+, notwithstanding its lack of incentives concerning spending outside of primary care, is a powerful enough reform that diverting practices away from ACOs is not a problem. ACOs are completely dependent on primary care physician membership to function, meaning that any physician practices beyond 1,500 that enroll in CPC+ will reduce the size and the impact of the ACO program. CMMI has never published a priority ranking of reform models, but its actions keep indicating that ACOs are at the bottom.

The Innovation Center should be lauded for continuing to support improved payment models for primary care. Its blending of substantial monthly payments with lower payments per service is promising. But the highest potential rewards come from broadening primary care physicians’ incentives to include the cost and quality of services by other providers. CMMI should pursue this approach.

Editor's Note: This blog post is part of The Primaries Project series, where veteran political journalists Jill Lawrence and Walter Shapiro, along with scholars in Governance Studies and the Campaign Finance Institute, examine the congressional primaries and ask what they reveal about the future of each political party and the future of American politics.

A great deal of attention has been paid to the existence of independent expenditure groups and to the billionaires who fund them. The Koch brothers and Sheldon Adelson, right wing billionaires in politics, and Tom Steyer, the newest left wing billionaire in politics, seem to have had nearly as much ink spilled on them as have the candidates and causes they endorse.  And no wonder. Americans are fascinated and worried about the question Darrell West poses in the second chapter of his new book Billionaires, “Can rich dudes buy an election?”

Tracking the sources and amounts of money in post Citizens United elections is a full time and complex job. Our hats go off to the Campaign Finance Institute who has recently completed the most extensive study ever of the role of independent expenditures in primary elections. Michael Malbin, Founding Director of the Center and author of the upcoming report on this year’s primaries, shows us just how big these groups, often funded by billionaires, have gotten.  In research focusing on independent spending in the 2014 congressional primaries, Malbin points out that in the 15 House races with the most independent expenditure money ($500,000 +) these expenditures counted for 76% as much as the candidates own campaign money. In Senate races, the independent expenditures accounted for 44% as much as the candidates own money.  Even the candidates themselves are worried about this trend since it often seems that outside groups can swamp a candidate’s own message.

Malbin also shows us why it is so hard to figure out what’s going on in an individual election. Only 49 of the 281 organizations that were around in the 2012 cycle spending money on behalf of congressional primary candidates were also around in 2014. That means that there were 232 new and different groups playing in 2014, posing challenges for the journalists and academics trying to track them.

The Campaign Finance Institute, however, has data on all these organizations from 2012 and 2014.  They have categorized them by ideology and, as the following chart shows, there are some interesting developments. For instance, while conservative independent expenditure groups remain the biggest spenders in the 2014 congressional primaries, their overall proportion of independent expenditures is down from 2012.  That year, conservative groups spent $40.5 million, nearly three quarters of total independent expenditures, compared to $9.3 million or 17 percent of total expenditures for Democrats.  In 2014, conservative groups upped their spending to $56.8 million, but their overall share of independent expenditures fell to 68% as liberal groups doubled their spending and increased their percentage of the total to 23%.

Even more surprising is the change in spending patterns within the Republican Party. As the following table shows, this really was the year when the establishment fought back. In 2012 anti-establishment spending by independent expenditure groups in congressional primaries constituted 59% of all such expenditures while spending by independent expenditure groups on behalf of establishment Republicans was only 36% of the total.  In two years, those numbers flipped.  In 2014, with control of the Senate at stake, the establishment mobilized independent expenditure groups which spent 55% of all the money spent by such groups while the anti-establishment groups spent only 37%.

There’s something for everyone in these findings. For the Democrats who have been on the defensive for much of this year but who have gotten through a primary season with few internal divisions, the increase in spending on their behalf and the sense that they will be able to run a good ground game in the key states where it really counts is a plus.

For the Republicans, the heavy spending by establishment groups has paid off in that they haven’t let weak candidates slip into the general election contest. They are probably as strong as they can be going into the fall campaign.

Nonetheless, tracking the money in this new election environment is a complex and full time job. And Darrell West’s question still hangs over us—“Can rich dudes buy an election?”

Lynn Neary: I'm Lynn Neary in Washington, sitting in for Neal Conan.

John Kerry may not have clinched the Democratic nomination for president in yesterday's primaries and caucuses, but his victories in five of the seven races certainly completed his rehabilitation from an also-ran to a front-runner. John Edwards and Wesley Clark also won last night, Edwards in South Carolina, Clark in a tight race in Oklahoma, where Edwards came in second. Joe Lieberman dropped out of the race altogether. Howard Dean vowed to fight on despite a dismal showing. So did Al Sharpton, who placed third in South Carolina. Dennis Kucinich barely registered with voters. All the candidates now have their eyes on the future with contests in delegate-heavy states now up for grabs.

Lynn Neary:...With us to talk about money in politics is Anthony Corrado. He's a professor of government at Colby College in Waterville, Maine, and is spending this year as a visiting fellow at The Brookings Institution here in Washington.

Thanks for being with us.

Anthony Corrado: Well, thanks for inviting me, Lynn.

Lynn Neary: Do we know exactly how much money's been spent so far by the candidates?

Anthony Corrado: Well, so far the Democrats have raised about $170 million in private donations and public funding all together, and all of that money's now been spent. This very competitive contest has proved to be very expensive so that as we enter this crucial part of the nominating process, no candidate really has a large reservoir of cash that's available to be spent.

Lynn Neary: Yeah. Both Dean and Kerry used the same strategy, focusing on Iowa and New Hampshire, but came up with very different results, didn't they?

Anthony Corrado: Yes, they did, and it was particularly problematic for Howard Dean because what Dean decided to do was use the large store of cash that he had raised in 2003 to spend lots of money in the states that would be voting in February, as well as in Iowa and New Hampshire, and as a result spent over $3 1/3 million on television in states that were voting after New Hampshire. Whereas John Kerry basically took all of the money he had and put it into Iowa and New Hampshire and was able to get the victories he needed to spur additional fund-raising so that he right now is in the best position even though he ended up raising much less than Howard Dean prior to New Hampshire. He's now in the best position to raise and spend money in this next stage of the race.

Lynn Neary: Yeah. And what about Dean? Has he been able to--he was so well-known for his fund-raising. How has his fund-raising been since he has started losing?

Anthony Corrado: Well, his fund-raising has actually held up very well. He's raising about a million dollars a week. He's raised about $3 million since that now-infamous night in Iowa. But one of the problems that he has is that he built such a large organization that it's very expensive to maintain. And as a result he has not had money for television advertising this week. He's not doing any television advertising in the states this weekend. And he probably won't do any television advertising in Tennessee and Virginia. So he's basically gone off of the airwaves in terms of paid television, with the exception of looking towards Wisconsin, which isn't until February 17th.
