2. Impacts
on Private Health Insurance & Supplements
Medigap
(Medicare Supplements)
Plans like Plan G grow in popularity among new enrollees, while Plan F is no longer available to new applicants.
· Kiplinger
· Unfortunately, premiums are rise: a Reddit user reported a 12% increase in 2025 for a Plan N supplement!
Private
Health Insurers Respond
Medicare’s reduced Part D exposure might pressure insurers to increase premiums or decrease plan features to offset costs.
In other markets, such as the ACT region in Australia, private insurers report stealth taxes (like ambulance levies) being passed to policyholders—a possible cautionary scenario.
