Millions of Americans on Humana's Medicare Advantage plans could see their health care benefits cut after the company makes major profit-boosting adjustments to its plans. Humana said it would be ending some plans and cutting benefits for patients in 2025 as it hopes to boost its financial performance.

Humana, the country’s second largest Medicare Advantage insurer, is aggressively culling its plan offerings after several quarters of spending more than expected on its members’ medical care, and getting hammered on Wall Street for it. The company will scrap Medicare Advantage plans in 2025 that currently cover about 560,000 members.

Humana reaffirmed its full-year guidance but is leaving 13 Medicare Advantage (MA) markets next year, Chief Financial Officer Susan Diamond said during the Wells Fargo Healthcare Conference on Wednesday. Other members will have fewer plans to choose from in certain geographies.

Humana Inc. (NYSE: HUM) will be exiting 13 Medicare Advantage (MA) markets in 2025, company leaders said during the Wells Fargo Healthcare Conference. The company had already announced that it was planning to leave markets next year, but offered up more specifics last week.

Bonus payments to Medicare Advantage plans are expected to fall by $1 billion this year, after the expiration of pandemic-era policies that temporarily increased plans’ star ratings, according to new research. The drop reverses a long period of growth in MA bonuses, which critics maintain increase the financial burden on Medicare.
