What California Medicare Beneficiaries Need to Know
If you already have a Medicare Supplement (Medigap) plan in California, the California Birthday Rule may give you the opportunity to change plans each year without medical underwriting.
This state law allows many Medicare beneficiaries to switch to another Medicare Supplement plan with the same or lesser benefits, helping them find a lower premium or a carrier that better meets their needs.
How the California Birthday Rule Works
Each year, beginning on your birthday, you have a 60-day window to change your Medicare Supplement plan.
During this period, eligible individuals can:
Switch to another insurance company.
Keep the same lettered plan (such as Plan G to Plan G).
Move to a plan with fewer benefits, if desired.
Change plans without answering health questions or going through medical underwriting.
Who Qualifies? Generally, you qualify if you:
Live in California.
Already have a Medicare Supplement (Medigap) policy.
Apply during your Birthday Rule eligibility period.
Timeline
📅 Your Birthday
↓
60-Day Enrollment Window Begins
↓ Compare available Medicare Supplement plans.
↓
Choose a plan with the same or fewer benefits.
↓
New coverage begins after approval.
What the Birthday Rule Does NOT Allow The Birthday Rule does not allow you to:
Switch from Medicare Advantage to Medicare Supplement under this rule. Purchase a plan with greater benefits than your current Medicare Supplement plan.
Enroll outside your eligibility window unless another guaranteed issue right applies.
Why It Matters
Many people keep the same Medicare Supplement plan for years without realizing they may have options.
The California Birthday Rule gives eligible beneficiaries an opportunity each year to review available plans and compare premiums while keeping similar coverage.
Reviewing your options annually may help you find a plan that better fits your needs and budget.
