In some cases, such as cancer diagnoses, misdiagnosis is common, and patients often benefit from a second opinion. In fact, up to one-third of cancer diagnoses are missed on initial presentation. However, some health plans might establish hurdles that prevent or at least make it difficult for patients to seek out second opinions. One possible solution is to support team-based centers that aim to improve the diagnosis of challenging conditions. In the United Kingdom and Denmark, for example, there is a push for multidisciplinary centers aimed at the rapid and simultaneous assessment of multiple cancers. These centers offer an accurate cancer diagnosis or an “all-clear” within 2 weeks. By limiting the conditions the center focuses on, generously reimbursing the multidisciplinary team approach, and concentrating experts into a center, they are able to improve accuracy and speed up the process of making a diagnosis. In comparison, under the current standard of care in the United States, it can take several weeks to months of seeing multiple physicians (at different institutions and who do not communicate well with each other) just to establish a diagnosis. Even then, the diagnosis may still be incorrect.

Berenson and Singh argue that a possible solution to inaccurate diagnoses is changing our current payment models. Recognizing this issue, the US Department of Health and Human Services recently proposed new rules for the upcoming 2019 Medicare Physician Fee Schedule that would reduce the current 4 levels of care for outpatient visits to a single level for new patients and a single level for follow-up visits.3 However, as the investigators pointed out, this strategy is likely to exacerbate the problem because now physicians will receive the same payment for a 5-minute encounter as they would for a 35-minute encounter. Where is the incentive in this proposed fee schedule for a clinician to take their time to get a diagnosis right? Instead, the proposed changes are likely to shorten the already brief patient encounters. One strategy is to move forward with payment models that promote accountability for diagnostic performance.3 An obvious model that comes to mind is that of Accountable Care Organizations (ACOs), in which providers share the cost savings when they reduce the total cost of care. While there are some performance metrics used, current ACO models do not necessarily or directly reward diagnostic accuracy, although they may indirectly do so in improved quality care metrics.

Finally, in condition-based payment models adopted by the Center for Medicare and Medicaid Innovation, there is concern that the lack of diagnostic accuracy predisposes these models to abuse.3 For example, in oncology, payment streams designed for patients with more severe forms of a qualifying diagnosis may be claimed by physicians for milder cases of that cancer for which the payment stream was not intended. The problem lies in that the payment is triggered by the initial claim for chemotherapy with little follow-up to verify the accuracy of the diagnosis and the level of severity.3 One possible solution is to build multiple opinions into the diagnostic process for conditions that are based more on expert opinion rather than objective confirmatory evidence.3

These solutions share a common theme: they all propose changes to how physicians are paid for the care they deliver. I have previously argued that it may be time to uncouple documentation from billing, which I believe would allow physicians to focus more on accurate documentation than on billing. Unfortunately, in our current healthcare model, which is so heavily reliant on documentation for billing, it is unclear how to uncouple the tasks and fairly compensate physicians for their time and efforts. It is worth considering whether a universal or single-payer healthcare system might more easily offer answers to improving diagnoses and reducing diagnostic errors. I point to the specialized cancer centers in the United Kingdom and Denmark as examples of how a single-payer system might improve not only diagnostic accuracy but care for more challenging conditions.
