Medicare Advantage

UnitedHealth, Presbyterian and Humana's 2027 Medicare Advantage Exits Trace to County Benchmark Math

UnitedHealth's 2027 Medicare Advantage list covers 34 counties; Presbyterian exits 30,000 members and Humana 600,000. The benchmark quartile, star rebate, and risk-score math decide which counties still clear a bid.

Risk Adjustment

Oscar Health's Loss Ratio Fell to 79.2 Percent. It Booked Only a Sliver of the Risk-Adjustment Upside Behind It

Oscar Health's medical loss ratio fell to 79.2% in Q2 2026 as membership grew 46% to 2.96 million, yet executives booked only a sliver of favorable risk adjustment on just four months of 2026 claims data.

Medicare Advantage

Humana Sheds 600,000 Medicare Advantage Members for 2027, Recaptures Fewer Than Half

Humana will exit Medicare Advantage plans covering 600,000 members for 2027, about 8% of its base, and expects to recapture only 240,000, a retention math that resets morbidity in its surviving risk pool.

Health Pricing

Cigna's 84.5% Medical Ratio Splits From the Medicare Advantage Trend Story

Cigna's Q2 2026 medical care ratio came in at 84.5%, versus Humana's 91.2% and Elevance's 89.7%, as softer surgical and outpatient spending split its commercial book from Medicare Advantage cost trend.

Medicare Advantage

Aetna's 250bp MBR Drop Rode a $471M Reserve Reversal

Aetna's Q2 2026 medical benefit ratio fell 250 bps to 87.4%, but $1.2B of six-month favorable prior-year development and a lapped $471M premium deficiency reserve did much of the work (CVS Health, August 2026).

Risk Adjustment

Centene's Marketplace Book Shrank 41%. Its Risk-Adjustment Position Swung Favorable With It

Centene's health benefits ratio fell to 89.6% and net income swung to $1.1 billion in Q2 2026, as its Marketplace book fell to 3.5 million from 5.9 million and risk adjustment turned favorable.

Health Pricing

UnitedHealthcare's June Plan F Reprice Lands Alongside 35%-Plus Closed-Block Filings

UnitedHealthcare repriced its AARP Plan F block up to $47.02 a month on June 1, 2026, while Humana, LifeShield National, and others filed 34% to 39% closed-block increases feeding Medigap's anti-selection spiral.

Medicare Advantage

Medicare Advantage's Quality Bonus Hits $13.4 Billion While the Qualified Base Shrinks to 68%

Medicare Advantage's quality bonus program will pay $13.4 billion in 2026, up from $12.7 billion, but the share of enrollees in bonus-qualified plans fell to 68% from 75%, reshaping rebate dollars for 2027 plan bids.

Employer Benefits

Medicaid Work Rule's 2.3M Exits Hit Self-Insured 2027 Assumptions

The Medicaid work rule took effect July 31; CMS projects 2.3 million exits in FY2027. Self-insured plans absorb the shift twice: sicker migrating enrollees, and uncompensated care repriced into commercial rates.
