Medicare’s open enrollment, which ends Dec. 7, is in full swing, leaving beneficiaries to ponder which plan they want for 2025. Changes are coming that might influence the decision.

One of the biggest changes takes effect in 2025. Part D drug plans must cap out-of-pocket spending on covered drugs at $2,000 a year. It will benefit enrollees with high drug costs by allowing enrollees to pay their prescription costs monthly rather than all at once.

Medicare open enrollment starts today, and there are big changes coming in 2025, including the elimination of the "donut hole," a $2,000 out-of-pocket-maximum, and more.
