Almost 35.5 million people were enrolled in a Medicare Advantage plan as of Feb. 1, up about 3% from 34.4 million at the same time last year, according to CMS data analyzed by Becker’s. Growth during the annual enrollment period (Oct. 15 to Dec. 7) was more modest, with enrollment increasing about 1%.
Seven things to know:
1. Total MA enrollment grew by about 300,000 from December to February. Non-SNP enrollment dipped by about 93,000 (-0.3%) while special needs plan enrollment increased by 393,000 (+5.1%). On a year-over-year basis, SNPs accounted for roughly 80% of all net MA growth.
2. Humana added more than 1.2 million MA members during the annual enrollment period, growing 21% from December to February to reach 7.04 million.
3. UnitedHealthcare dropped from 10.3 million in December to 9.4 million in February, a decline of about 915,000, or 9%. The company previously said it expects to lose up to 1.4 million MA members this year.
4. Elevance Health’s MA membership dropped from 2.2 million in December to 1.9 million in February, a 14% decline.
5. Aetna dropped 94,000 members (2%) to 4.1 million. HCSC, which absorbed Cigna’s Medicare business in 2025, shed about 10% of its members during annual enrollment, ending at 881,000. BCBS Michigan membership declined by 15%, dropping 117,000 members to a total of 679,000.

Alignment Healthcare grew 18% to 277,000 total.
7. Total SNP enrollment reached roughly 8.2 million as of February, becoming nearly 23% of total MA enrollment. Dual-eligible SNPs remain the largest category at 6.4 million, followed by chronic condition SNPs at 1.6 million and institutional SNPs at about 129,000.
