Forced disenrollment rates averaged about 1% of enrollment annually from 2018–2024 but increased sharply in 2025 and 2026. Disruptions are more common among beneficiaries enrolled in PPO plans, plans offered by smaller carriers, and those living in rural areas.

New paper out today in JAMA with @LavalleeMat, Matthew Zahn, @FrankXu_PhD, and @healthecon_dan where we document a substantial increase in plan exits from Medicare Advantage in 2026.
Approximately 1 in 10 MA beneficiaries have been forced to leave their plan in 2026.
JAMA@JAMA_current
Forced disenrollment from #MedicareAdvantage plans will reach 10% in 2026, affecting millions—particularly those in rural areas, PPOs, and lower-rated plans. 🧵 ja.ma/4alUORy

New paper out in @JAMANetworkOpen led by @JohnsHopkinsSPH HPM PhD student Matthew Lavallee.
This new paper highlights a potential tradeoff enrollees may face when selecting Part B giveback plans in MA: narrower provider networks for most specialties.
JAMA Network Open@JAMANetworkOpen
Medicare Advantage plans with Part B premium givebacks had narrower physician networks compared with plans without givebacks, especially among those offering larger giveback amounts. ja.ma/4k0w8kK

As of this morning, Baltimore has seen a 29.8% decrease in homicides and a 25.2% decline in non-fatal shootings.
As we enter the last month of the year, we are doubling down on our work to continue this progress into 2026 and beyond. One life lost to violence is one too many.

the most under-appreciated local government success over the past three years? it’s actually Baltimore imo
-murders down 60%
-major pro-housing reforms including ending parking mandates, legalizing single-stair buildings, and permitting denser housing

Today, I signed a package of bills to make housing in Baltimore more abundant and affordable. These bills will help folks buy a home and grow wealth, counter decades of disinvestment, and make sure both long-time and new residents feel the benefits of Baltimore's Renaissance.
