RAND expert survey finds no Medicare Advantage reform that satisfies all sides

A new RAND analysis of Medicare Advantage policy options lands on a central truth of U.S. health policy: the same reform rarely looks equally good from the perspective of beneficiaries, insurers and government purchasers. In a Delphi survey of 52 experts drawn from research, the Medicare Advantage industry, patient advocacy and policymaking, no single proposal among 14 rose to the level of broad approval across all three stakeholder groups.

The result is not merely a political inconvenience. It reflects the basic structure of the Medicare Advantage market, where benefits, premiums, provider networks and administrative rules are interlocked in ways that shift gains from one group to another. A change that improves patient choice can compress insurer margins. A change that lowers federal spending can do so by making traditional Medicare less competitive or by forcing a more disruptive reallocation of risk. In that sense, the study maps the practical limits of consensus before any bill, rule or court challenge ever takes shape.

The analysis comes at a moment of intensified interest in Medicare Advantage reforms from both parties, and that setting matters because policy attention tends to sharpen around visible friction points: supplemental benefits, prior authorization, marketing practices, agent commissions and the overall complexity of plan selection. RAND used a Delphi process, asking panels multiple rounds of questions to see where agreement might emerge after experts had time to revise their judgments. Even with that iterative design, consensus remained out of reach on the full set of proposals.

Dmitry Khodyakov, a senior sociologist at RAND and one of the study’s authors, framed the result as evidence of how difficult it is to change anything tied to healthcare financing. The core problem is distributional. Every Medicare Advantage reform reallocates value, whether the benefit lands with enrollees, insurers or the federal budget, and in a system as large as Medicare, those trade-offs show up quickly.

The reform most attractive to enrollees creates the sharpest insurer and federal trade-offs

One proposal stood out as especially favorable to enrollees: strengthening traditional Medicare so it competes more effectively with Medicare Advantage. On paper, the logic is straightforward. If original Medicare offered supplemental benefits, established an out-of-pocket maximum and addressed cost-sharing, it would become more attractive to many beneficiaries who now gravitate toward MA plans for their added benefits and perceived financial protection.

The biological analogy is less relevant here than the economic one, but the policy mechanism is just as direct. Improve the baseline product and market behavior shifts. Beneficiaries with more complete coverage options may decide they no longer need MA’s extra perks to feel protected against high medical bills. That could reduce MA enrollment, which would likely weaken plan profitability and alter the risk pool insurers depend on.

The federal budget picture is more complicated. If the government expands traditional Medicare without achieving payment parity across the two programs, lower Medicare Advantage outlays could be offset by higher spending in original Medicare. Any savings would depend on a broader market disruption that changes how beneficiaries move between programs. That is precisely the kind of large-scale transition policymakers often say they want but rarely want to engineer in practice.

Three near-term ideas drew the strongest practical support

Against that backdrop, three proposals emerged as the most plausible near-term reforms because they could improve the enrollee experience without forcing major disruption for plans or the government. Those ideas were standardizing supplemental benefits, reforming commissions for agents and limiting the number of plans an insurer can offer.

Each addresses a different source of confusion in the MA market. Standardized supplemental benefits would make plan comparisons easier and reduce the noise created when plans advertise different mixes of extras. Commission reform could reduce incentives that distort enrollment decisions when brokers steer beneficiaries toward plans based on compensation rather than fit. Limiting the number of plans an insurer can offer could also simplify choice, a meaningful issue in a market where beneficiaries often face an overwhelming array of options that differ in ways that are hard to parse.

Erin Taylor, a senior economist at RAND and another author of the analysis, said those three ideas clustered together because they address well-documented issues that complicate choice. The policy appeal is not only that they could help enrollees; it is also that they may be feasible through rule-making rather than requiring congressional action. That makes them the kind of reforms regulators can actually move, even in a politically fractured environment.

When reforms can be implemented administratively, they face fewer legislative veto points and can be adjusted as the market responds. For insurers, there may even be some upside. Cleaner benefit structures, less convoluted marketing and fewer plan offerings could support better member retention, improve the consumer experience and reduce administrative complexity. The market would still be competitive, but competition would operate on a narrower and more intelligible field.

Trade-offs, not universal winners, define the policy debate

The most important conclusion is not that Medicare Advantage reform is impossible. It is that no proposal in this set fully aligned the interests of all parties. Policymakers, in turn, have to be explicit about what they are trying to optimize: lower federal spending, greater beneficiary protection, simplified choice, reduced administrative burden or some combination of the four.

RAND’s findings also suggest why consensus statements in healthcare often sound clearer than the reality behind them. Everyone can agree that beneficiaries should not be misled, that plan choice should be understandable and that spending should be restrained. Disagreement starts when the proposed remedy creates winners and losers in the same transaction. In Medicare Advantage, that tension is built into the program’s structure.

Khodyakov said continued polling of expert panels could help track whether views shift as policy priorities change. That would matter in a market where enrollment, benefit design and regulatory scrutiny are all moving targets. Taylor characterized the work as a first step along a policymaking path, a careful way to identify which reforms can move forward without requiring a wholesale redesign of the Medicare market.

For now, the study leaves policymakers with a blunt but useful message: the easiest Medicare Advantage reform to explain is not the easiest one to enact, and the reforms most likely to help beneficiaries are often the ones that force the clearest trade-offs. The unanswered question is whether regulators will choose modest administrative fixes or decide that deeper structural changes are worth the political and budgetary cost.
