Socially weak counties are much less prone to have higher-rated Medicare Benefit plans, which is probably going worsening well being disparities, a brand new examine discovered.

The examine was revealed Tuesday in JAMA Community Open and was performed by researchers at New York College, The Commonwealth Fund and Brown College.

Medicare Benefit enrollment is rising: greater than half of all Medicare beneficiaries are enrolled in Medicare Benefit plans over conventional Medicare. Every year, the Facilities for Medicare and Medicaid Companies (CMS) offers Medicare Benefit packages a ranking on a scale of 1 to 5 stars. The rankings, that are primarily based on 40 indicators, are supposed to inform beneficiaries on the standard of well being plans. CMS additionally offers extra funding to plans with greater star rankings, which they’ll use to supply higher supplemental advantages for members.

The researchers used CMS’ 2023 star rankings and mapped the provision of Medicare Benefit plans in 3,075 counties throughout the U.S. Additionally they examined county-level traits utilizing the Social Vulnerability Index from the Facilities for Illness Management and Prevention. This index evaluates 16 social determinants of well being, similar to poverty, unemployment, training, incapacity, race and ethnicity, English language proficiency, housing, and entry to transportation.

They discovered that deprived counties had been much less prone to have plans with 4.5 stars or greater and extra prone to have plans with 3.5 stars or decrease.

“If the star ranking is decrease than relative to different plans, the plans will receives a commission much less,” stated Avni Gupta, the lead creator of the examine and researcher on the Commonwealth Fund, in an interview. “Then it’s doubtless that they’ve decrease assets than different plans to supply these [supplemental] advantages as effectively. If these low-rated plans are concentrated in areas which can be already socially weak, that exhibits us that it’s going to simply exacerbate the inequities. Individuals who may profit essentially the most from these advantages … may solely have choices to enroll in plans which have decrease cost charges.”

The examine makes two coverage recommendations. The primary is to switch the standard bonus funds related to the star rankings.

“The CMS plans to start adjusting the star ranking measures in 2027 utilizing a well being fairness index, which is able to penalize plans that fail to offer equitable expertise and outcomes to all their enrollees,” the examine stated. “Together with this important step towards incentivizing fairness, accounting for regional vulnerabilities in plan funds might additionally incentivize plans serving weak areas and keep away from greater funds to plans with greater high quality rankings that don’t serve weak beneficiaries.”

The opposite suggestion is for CMS to offer plan-level star rankings somewhat than contract-level. Star rankings are presently revealed for contracts as a complete and apply to all plans inside every contract. Nonetheless, completely different plans inside a contract could also be serving completely different counties with completely different ranges of well being disparities.

“I feel there’s a clear knowledge limitation right here that we can’t instantly affiliate a plan ranking with high quality. … We actually need our examine to form of scope CMS’ excited about modifying the star ranking system and cost system,” Gupta stated.
