How does California’s Medicare Supplement Birthday Rule work?
California’s Birthday Rule gives current Medigap policyholders an annual 60-day opportunity to move to a plan with the same or fewer benefits without medical screening.
By Greg Bass · September 2, 2026California has a Medicare Supplement rule called the Birthday Rule.
If you already have a Medicare Supplement, it gives you 60 days following your birthday each year to switch to a plan with the same or fewer benefits, including a qualifying plan from a different company.
During that protected period, you can make the change without medical screening or a new waiting period.
Because companies can charge different premiums for the same standardized lettered-plan benefits, the rule may let you keep the same Plan G, Plan N or other qualifying coverage while paying a lower premium.
Depending on the available rates, that could potentially save more than $1,000 a year—making the Birthday Rule one of the rarest of creatures: a truly beneficial California regulation.
