Current Intelligence — Q2 2026
What Changed Policy & Regulation
$2,000 Part D cap is live. The IRA out-of-pocket cap took effect January 2026. 3.2M beneficiaries are projected to hit the cap by year-end.
V28 risk model fully phased in. CMS completed the transition from V24 to V28 HCC risk adjustment. High-acuity plans face meaningful revenue shifts.
Star crash continues. 5-star plans dropped from 89 (2022) to 11 (2026). Bonus revenue pressure is reshaping plan strategy.
What Matters Market Signals
MA penetration crossed 50% nationally. 2026 is the first year Medicare Advantage enrollees outnumber Traditional Medicare. 54.2% penetration rate — CMS OEC, March 2026.
Humana exits 13 markets. ~560K members are orphaned, creating significant redistribution opportunity. UHC and Centene are primary capturers.
MLR pressure reshaping benefits. Medical loss ratios are tightening across large carriers. Supplemental benefit reductions are the primary lever.
What to Watch Forward Signals
2027 Star ratings in flux. CMS preview data signals further star erosion for several large plans. Bonus threshold risk is material for 2026 bids.
D-SNP consolidation accelerating. FIDE-SNP growth is outpacing HIDE-SNP as states tighten alignment requirements. New integrated care requirements effective 2027.
NADAC pricing impacts formulary design. IRA drug price negotiations are changing formulary tier placement decisions. Part D sponsors are reassessing preferred drug lists.

How It Works
01
Choose a module
Five focused modules cover Enrollment, Plan Design, Geographic, Quality & Stars, and Regulatory. Each one answers a specific category of MA market question.
02
Filter to your market
Narrow any view by state, county, carrier, plan type, or year. All filters apply instantly across charts, tables, and trend lines.
03
Analyze, don't just display
Every figure is sourced to a specific CMS file and date. Plain-language commentary explains why a number moved, not just what it is.
04
Export with citations
Download any filtered dataset as CSV. Source citations are embedded in each export so figures are defensible in strategy decks, RFPs, and regulatory filings.
Why Trust This Data
Built on public data.
Never on estimates.
MedicareInsights.org applies a strict editorial standard: every figure is traceable to a specific CMS public file, every chart carries a source date, and no carrier pays to influence the analysis. The platform exists to make CMS data accessible — not to sell any plan.
CMS Source
Public CMS data only
All enrollment, cost, and quality data comes from CMS.gov public use files: OEC monthly enrollment, the CMS Medicare Landscape file, and CMS Part C & D releases. No proprietary estimates.
Dated
Source date on every chart
Enrollment runs through the March 2026 CMS Monthly OEC release. Star ratings reflect the most recent CMS Part C & D annual report. Every visualization shows its exact source date.
Cited
Every figure is cited
Source citations appear beside each chart and inside every CSV export. Projections and methodology notes are labeled clearly as estimates, not facts.
Independent
No carrier relationships
MedicareInsights.org has no affiliation with any insurance carrier, CMS, HHS, or Medicare.gov. No carrier pays to appear, rank higher, or receive favorable treatment in any analysis.
Who uses this?
Medicare Advantage organizations, health plan analysts, independent brokers, policy researchers, and consulting teams that need defensible, cited MA market data for strategy work, competitive analysis, or regulatory submissions.
How current is the data?
Enrollment figures reflect the latest CMS Monthly OEC release (typically 6–8 weeks behind the reference month). Star ratings update annually with the CMS Part C & D release. Source dates appear on every chart.
What's free vs. what requires an account?
Core enrollment trends, carrier market share, and quality ratings are free with no account. County-level drill-downs, advanced plan comparisons, and CSV export with citations require a free account.
