How is Medicare Advantage developing in New Hampshire?
New Hampshire's MA-and-other health plan share is 31.3% — below the 51.1% national share by 19.8 points, ranking 47 of 53 with 112,691 people in a Medicare Advantage or other Medicare health plan out of 359,816 Medicare beneficiaries, on the CMS state record for April 2026.
Share and enrollee counts are the CMS state record for April 2026 (Medicare Monthly Enrollment). Summing this state’s 10 county rows gives 31.4% on 359,290 beneficiaries, a difference of 526 beneficiaries CMS does not assign to a county. Both figures are published; the state record is canonical for the state. Dual counts are county-file aggregates.
