Announced

Medicare Advantage 2027: lower average premiums, thinner benefits

CMS announcement Sept 28, 2026; open enrollment Oct 15 – Dec 7, 2026

From Briefing for the week of September 30 – October 7, 2026

What changed

CMS reported the average Medicare Advantage premium falling from $14.37 to $12.00 for 2027, with about 34 million enrollees (47.4% of eligible beneficiaries). Trade reporting says insurers are trimming dental and Part B premium giveback benefits and expect an enrollment drop of roughly 6%, which CMS disputes.

Why it matters

Lower headline premiums can coexist with weaker coverage. Benefit reductions shift costs to enrollees at the moment they choose plans, and the dispute over the enrollment forecast shows how much of this remains projection.

  • Quality
Warrants deeper follow-up. Compare plan-level benefit changes to the CMS averages once plan data is public.

Litigation

Appeals court hears challenge to Medicare Advantage RADV audit rule

Argument reported Oct 5, 2026; district court ruling Sept 2025

From Briefing for the week of September 30 – October 7, 2026

What changed

The Fifth Circuit heard HHS's appeal in Humana v. Kennedy. A district court invalidated the risk-adjustment data validation (RADV) rule in September 2025, and HHS appealed that November. STAT reports the appellate panel appeared skeptical of the government's position. No decision has issued.

Why it matters

RADV audits are the main tool for recovering overpayments tied to inflated diagnosis coding in Medicare Advantage. A loss for HHS would weaken accountability for the program's largest payment-integrity risk.

Warrants deeper follow-up. Watch for the opinion and any HHS response on extrapolation methodology.
