Star ratings: fifteen billion dollars a year, on measures Congress's advisers call flawed

MedPAC told Congress in 2024 that Medicare Advantage quality measurement is flawed and not a reliable basis for judging plans, yet the bonus programme it feeds adds about fifteen billion dollars a year to plan payments.

Caveat on this rating: MedPAC's estimates are contested by the plans and their trade association; the commission's methods are published and its critics' are not summarised here.

Significant findings

If you are in a Medicare Advantage plan, your screens and diagnoses also feed a second system: the star ratings. The Medicare Payment Advisory Commission, which advises Congress, described it in March 2024. "Medicare currently collects close to 100 MA quality measures, 40 of which are used to determine a star rating from 1 to 5"; "since 2012 the star rating system has been the basis for the QBP, which increases benchmarks for MA contracts rated 4 stars or higher."

Its judgement: "the Commission has determined that the current system for MA quality reporting and measurement is flawed and does not provide a reliable basis for evaluating quality across MA plans. Nonetheless, these measures are the basis for the MA quality bonus program (QBP), which uses trust fund and taxpayer dollars to increase MA payments by about $15 billion annually." "Forty-two percent of all MA contracts are in bonus status for 2024" and "Roughly three-quarters of MA enrollees are enrolled in contracts with a 4-star rating or higher."

The wider finding: Medicare "spends an estimated 22 percent more for MA enrollees than it would spend if those beneficiaries were enrolled in FFS Medicare, a difference that translates into a projected $83 billion in 2024", and "MA plans' diagnostic coding practices increase payments and distort the goal of plans competing to improve quality and reduce health care costs."

Worth asking

This money is the plan's, not your doctor's. It is on this page because the forms you fill in and the diagnoses recorded at your visits are inputs to it. Which measures actually feed the stars is in the next row, and the answer for depression is not what most people assume.
