CMS announced the increase on April 1, 2019:
Today, the Centers for Medicare & Medicaid Services (CMS) finalized updates that will take significant steps in continuing the Trump administration’s efforts to increase competition among Medicare Advantage and Part D plans so patients get higher quality care at lower costs. These changes will increase plan choices and benefits, and include important actions to address the opioid crisis.
“Today’s changes give plans the ability to be innovative and offering benefits and services that address social determinants of health for people with chronic disease,” said CMS Administrator Seema Verma. “With Medicare Advantage enrollment at an all-time high, plans need greater flexibility in offering benefits that they focus on preventing disease and keeping people healthy.”
