MACRA creates two pathways for physician payment. There’s the Merit-Based Incentive Payment System (MIPS), which will pay doctors based on how they score on a number of performance metrics relative to their peers. The second pathway will reward doctors who participate in Alternative Payment Models (APMs) meant to promote high-quality, cost-efficient care by incentivizing doctors to work together toward a common purpose: improving patient outcomes while eliminating unnecessary spending.
This sounds good, but all the emphasis on better quality care comes with a trade-off. To assess the quality of care provided by doctors in the MIPS pathway, the physicians will have to report on a number of measures that many feel do nothing to help them improve the care they provide.
Doctors already devote a considerable amount of time reporting on quality measures. A recent analysis found that a typical medical practice currently spends, on average, 785.2 hours a year per physician to track and report quality measures. That’s time away from patient care, and the costs — $40,069 per physician — present a particular hardship for small, independent practices operating on narrow margins. Moreover, three-quarters of the doctors surveyed felt that the measures did nothing to help them improve their care.
One recent survey of physicians found nearly 40-percent expect a "mass exodus" from Medicare over MACRA.
