## Claims

### 46 Medicare plans are available in Santa Clara, California for contract year 2026

**DERIVED.** The CMS CY2026 Medicare Landscape Files record 46 Medicare Advantage and Part D plans available in Santa Clara, California. Atlas Commons counted the rows; CMS published the underlying plan×county records, not this county-level total.

Source: CMS CY2026 Medicare Landscape Files — https://www.cms.gov/medicare/health-drug-plans/medicare-advantage/plan-information/plan-information
Falsifier: occurred=TRUE: a faithful COUNT/SUM/total over the named record set that introduces NO modeling choice — it IS the case in the record. adjudged=FALSE: Atlas Commons computed the aggregate; CMS CY2026 Medicare Landscape Files published the underlying records, NOT this figure. Re-count it from the named source to verify. Distinct from a median/ratio/index (which picks a population, weighting, denominator, or threshold — a constructed statistic → 'derived', occurred=FALSE) and from an authority-published total (→ 'recorded', adjudged=TRUE).

### Monthly premiums for Medicare plans in Santa Clara, California range from $0.00/mo to $204.00/mo (CY2026)

**RECORDED.** The CMS CY2026 Medicare Landscape Files publish per-plan monthly consolidated premiums for Santa Clara, California. Across the 46 plans with a published premium, the range is $0.00/mo to $204.00/mo. These are the plan's base monthly premium — your actual cost depends on income-related adjustments (IRMAA), any applicable Low Income Subsidy (LIS/Extra Help), and your Part B premium. A $0 plan premium does not mean $0 total cost.

Falsifier: Verify in the CMS CY2026 Medicare Landscape Files for Santa Clara, California. Falsified if the CMS-published per-plan premium figures differ.

### CMS assigned star ratings to 42 of 46 Medicare plans in Santa Clara, California (CY2026); average overall: 3.7 stars

**PROJECTED.** CMS issued Overall star ratings (1–5 stars) to 42 of 46 Medicare plans in Santa Clara, California for CY2026. The unweighted average overall star rating across rated plans is 3.7. Star ratings are CMS quality scores — an institutional determination, not a measured event. A higher rating reflects better performance across CMS quality measures. Ratings cover the contract's overall performance, not this county specifically; a plan may be available in your county with a rating earned across its full service area.

Falsifier: Verify CMS star ratings for these contract IDs at the CMS Medicare Plan Finder or the CMS star ratings dataset. Falsified if the CMS-published ratings for these contracts differ. Note: PDP-only plans and newly contracted plans may not have an overall star rating — the 4 unrated plans in this county are not rated, not unqualified.

### What these Medicare plan figures are — and are NOT — for Santa Clara, California (the epistemic boundary)

**INTERPRETATION.** This page lists Medicare Advantage (MA) and Part D Prescription Drug Plan (PDP) plans available in Santa Clara, California for CY2026, with their CMS-published base premiums and CMS star ratings. The premiums shown are the PLAN's base monthly premium — your actual monthly cost depends on the Part B premium (deducted from Social Security for most enrollees), income-related premium adjustments (IRMAA), and any Low Income Subsidy (Extra Help). A star rating is CMS's quality score for the plan's overall performance — a higher rating is generally better, but the "best" plan depends on your specific prescriptions, preferred doctors, and budget. This surface informs and compares; it does NOT rank plans, recommend a "best" plan, or account for your individual situation. To compare plans with your specific drugs and providers and to enroll, use the official Medicare Plan Finder at medicare.gov/plan-compare.

Falsifier: occurred=FALSE (a framing) and adjudged=FALSE (the atlas's reading, not a CMS verdict) — the LOWEST-warrant claim here.
