Key Takeaways Explain This Topic AI
California's Birthday Rule gives a yearly open enrollment of 60 days or more, beginning on the policyholder's birthday (Insurance Code 10192.11(h)); the insurer must send notice 30 to 60 days before it starts
During the Birthday Rule window the insured may buy a Medigap plan with equal or lesser benefits, from any company, without denial or higher pricing for health, as long as another Medigap policy is in force
The federal 6-month Medigap open enrollment begins the first month the person is both age 65 and enrolled in Medicare Part B, giving full guaranteed issue
California adds its own windows: six months of open enrollment after any employer or retiree plan ends (COBRA and Cal-COBRA included) and an extra 60 days after a Medicare Advantage termination; the federal 63-day windows still apply
Medigap plans are federally standardized A through N; Plans C and F are closed to anyone first eligible for Medicare on or after January 1, 2020
Last updated: November 2026
California has adopted unique consumer protections for Medicare beneficiaries who buy Medicare Supplement (Medigap) insurance. The best known is the California Birthday Rule .
The Birthday Rule (Insurance Code 10192.11(h))
Each year a Medigap policyholder gets an open enrollment period lasting 60 days or more , beginning on the birthday. The insurer must notify the policyholder of this right at least 30 and no more than 60 days before the window opens.
How It Works
The window begins on the policyholder's birthday and lasts at least 60 days .
The insured may switch to any Medigap plan with equal or lesser benefits .
The new policy may be from any insurer , including the current one.
No denial or surcharge for health — as long as the person is covered by another Medicare supplement policy when the window opens.
- Rule Requirement
- Timing Starts on the birthday; at least 60 days
- Plan options Equal or lesser benefits only
- Insurer Any company permitted
- Underwriting No denial or health pricing while another Medigap policy is in force
- Frequency Once per year
Exam Tip: The California Birthday Rule window is 60 days or more , and it begins ON the birthday, not the first of the birth month.
Worked Example
Maria turns 70 on March 15. Her Birthday Rule window starts March 15 and lasts at least 60 days. She currently holds Plan G . She may move to another carrier's Plan G (equal benefits) or a plan with fewer benefits, without being turned down or charged more for her health. She may not jump to a richer plan such as Plan F using the Birthday Rule, because the rule caps her at equal-or-lesser benefits.
Federal 6-Month Open Enrollment
Separate from the Birthday Rule, every Medicare beneficiary gets a one-time 6-month Medigap Open Enrollment Period (OEP) .
When It Begins
The 6 months start on the first day of the month in which the person is both :
Age 65 or older , AND
Enrolled in Medicare Part B .
Protections During OEP
Guaranteed issue — must be accepted regardless of health.
No pre-existing condition waiting period if the applicant had at least 6 months of prior creditable coverage.
Standard (not surcharged) rates — cannot be charged more for health conditions.
Any standardized plan A through N may be chosen, including richer plans (unlike the Birthday Rule's equal-or-lesser cap).
Guaranteed Issue Rights (Outside OEP)
Federal law grants guaranteed issue in specific situations, generally with a 63-day application window. California adds longer or extra windows in Insurance Code 10192.11:
Triggering Event California Right
Any employer-sponsored plan ends, including a retiree plan, COBRA or Cal-COBRA (Part B enrollee) Six months of open enrollment from the termination notice, or from the end date if no notice comes
Divorce or death of a spouse ends eligibility under an employer plan Six months from the notice or the end date
Medicare Advantage plan terminates the person's coverage An extra 60 days added after the federal open enrollment period
- Medigap coverage ends because the person moved outside the plan's service area Open enrollment
- Income or assets rise so the person is no longer eligible for Medi-Cal Open enrollment
Medigap insurer becomes insolvent or ends the policy through no fault of insured Switch to a comparable plan (federal)
Medicare Advantage Trial Right
If a beneficiary drops a Medigap plan to try Medicare Advantage for the first time , they have 12 months to change their mind and return — guaranteed issue, no health questions — to their old Medigap plan (or another guaranteed-issue plan if the old one is unavailable).
Standardized Plans A Through N
Medigap plans are federally standardized ; benefits are identical across insurers for the same letter, so the only real differences are price and service.
- Plan Notable Feature
- A Core benefits only
- B Core + Part A deductible
- C Comprehensive incl. Part B deductible (closed to new eligibles 2020+)
- D Like C without Part B excess charges
- F Most comprehensive; covers Part B deductible (closed to new eligibles 2020+)
- G Like F but does NOT cover the Part B deductible
- K 50% cost sharing with annual out-of-pocket max
- L 75% cost sharing with annual out-of-pocket max
- M Covers 50% of Part A deductible
- N Lower premium; copays for some office and ER visits
Important: Plans C and F are closed to anyone first eligible for Medicare on or after January 1, 2020 . For new enrollees, Plan G is the most comprehensive available, which is why G is now the top seller.
Rate Regulation
Medigap policies use one of several rating methods, and the method determines how premiums rise over time:
Attained-age rating: premium increases as the insured ages.
Issue-age rating: premium set by age at purchase and does not rise solely with age.
Community rating: same premium regardless of age.
Rate increases must be filed with the CDI, and a producer replacing coverage must complete the standard replacement notice.
Marketing and Replacement Safeguards
California tightly regulates Medigap sales to protect seniors. A producer must:
Deliver the Guide to Health Insurance for People with Medicare and an Outline of Coverage at or before application.
Never sell a beneficiary more than one Medigap policy (duplication is prohibited).
Never sell Medigap to someone enrolled in Medicare Advantage unless they are disenrolling, because Medigap cannot pay Advantage cost sharing.
Complete a replacement form and avoid high-pressure tactics; California prohibits twisting (misrepresentation to induce replacement) and churning (needless internal replacement for new commission).
Common Exam Traps
- Trap Reality
- "Birthday Rule lets you upgrade to any plan" Only equal or lesser benefits
- "Window is 30 days" 60 days or more (Insurance Code 10192.11(h))
- "Window starts the first of the birth month" Starts ON the birthday
- "Plan F is still open to everyone" Closed to those first eligible 1/1/2020 or later
- "You can stack Medigap with Medicare Advantage" Prohibited — they do not coordinate
Exam Tip: Medigap supplements Original Medicare only. A beneficiary cannot use a Medigap policy to fill gaps in a Medicare Advantage plan, and selling one for that purpose is an unfair practice.
