Methodology: plan counts, premiums, out-of-pocket maximums, Part D deductibles, and star ratings are computed from the CMS PY2026 Landscape source files for Butte County, South Dakota. Headline "average premium" and "$0 premium" figures use the Part C premium; the consolidated Part C + D premium is reported separately. Special Needs Plans (D-SNP, I-SNP) and Medicare Cost plans are excluded from Medicare Advantage averages and shown separately. County enrollment sums CMS contract-level enrollment for Butte County; CMS suppresses counts under 11, so totals are conservative. Health prevalence figures are CDC PLACES model-based estimates. Content is prepared by the Big Sioux Benefits Data Desk and reviewed for accuracy against the cited files; plan details change — verify with a licensed agent before enrolling.
