Note: Enrollment in Medicare Advantage plans is poised to surpass enrollment in traditional, fee-for-service (FFS) Medicare in 2023. MA's rapid growth raises major questions about the shape of Medicare coverage going forward. This is the first of two posts examining the pros and cons of Medicare Advantage. This post outlines the major issues as framed by MedPAC and select researchers, along with the basic economic tradeoffs for enrollees. Part 2 will report the experience of a hospitalist, brokers, and various stakeholders who responded to a CMS request for feedback about the MA program.
There is a slipknot quality to attempts to compare the value and utility of traditional, fee-for-service (FFS) Medicare and Medicare Advantage.
Medicare Advantage plans generally place bids to CMS far below CMS benchmarks, which are based on an adjusted estimate of what it costs to provide FFS Medicare to enrollees in the plan's geographic area. On average, according to the 2022 MedPAC report, MA plans spend 15% less to provide Part A and B benefits than FFS Medicare would spend. But CMS pays Medicare Advantage plans an average of 104% of what it would pay for FFS Medicare coverage for the same enrollees. But MA plans use the excess payment to provide an estimated $2,000 per member in surplus benefits or out-of-pocket cost relief. But, according to MedPAC, the value of MA-furnished extra services as actually used by enrollees is elusive, because of inadequate reporting requirements, and the quality ratings that increase payments to MA plans do a poor job measuring quality.
With regard to outcomes, MA plans employ treatment protocols that do minimize some so-called low-value care and, in some cases at least, boost usage of preventive care that, according to some studies, can reduce cardiac events, foot amputations for diabetics, ER trips, hospital admittances, and other conditions and services. But there is also good evidence that MA plans inhibit or impede access to needed or high-value care, introduce expensive and sometimes dangerous bureaucratic hurdles to obtaining needed care, and drive enrollees with intense medical needs back to FFS.
Most notoriously, by multiple accounts, MA plans often impede, block, limit options and reduce the duration of post-acute care. Comments about MA that CMS recently solicited from stakeholders detail these complaints (from physician and hospital associations, practitioners, acute care personnel, patients, brokers and others) again and again and again. A major strain in these complaints is from state employees forced into MA plans by retirement benefit packages.
This month, the Kaiser Family Foundation published a report, based on a literature review of 62 studies published since 2016, comparing "Beneficiary Experience, Affordability, Utilization, and Quality in Medicare Advantage and Traditional Medicare." The authors' conclusions are...inconclusive:
