Frequently Asked Questions
Frequently Asked Questions
What is the difference between Medicare Supplement and Medicare Advantage?
Medicare Supplement (Medigap) pays the gaps in Original Medicare and works with any provider that accepts Medicare nationwide — no networks, no referrals, predictable monthly costs (premium + Part D + a small Part B deductible). Medicare Advantage replaces Original Medicare with a private plan that has networks, may require referrals, often has $0 monthly premium but higher out-of-pocket exposure (up to $9,350 in 2026 for in-network), and bundles in extras like dental and vision. Medigap is the gold standard for provider freedom; Advantage is competitive for healthy retirees willing to use a network.
How much does Medicare Supplement Plan G cost in Orange County in 2026?
For a 65-year-old female non-smoker, Plan G in OC ranges from $108–$215/month depending on carrier. The lowest-priced highly-rated carriers (Mutual of Omaha, UnitedHealthcare AARP, Humana, Cigna at age 65) start around $108–$138/month. Median market pricing is $138–$162/month. Higher-priced carriers run $185–$215/month for the identical coverage. Male non-smokers pay 7%–10% more. Premiums increase with age — typical 80-year-old pays $172–$310/month for the same Plan G.
What is the California Birthday Rule for Medicare Supplement?
California’s Birthday Rule allows any Medigap enrollee to switch to any Medigap plan of equal or lesser benefits with any carrier during a 60-day window starting on their birthday — with no medical underwriting required. This means you can switch from an aging Plan G priced at $260/month to a fresh-pricing Plan G priced at $165/month without health questions, regardless of conditions. Most OC Medigap clients save $400–$1,800/year by using the Birthday Rule annually. A good broker calls every birthday to run the comparison.
Can I switch from Medicare Advantage to Medicare Supplement?
Yes, but typically with medical underwriting. The annual Medicare Open Enrollment Period (Oct 15–Dec 7) and the Medicare Advantage Open Enrollment Period (Jan 1–Mar 31) let you leave Advantage and return to Original Medicare. To add Medigap with that switch, you generally face medical underwriting unless you qualify for a Guaranteed Issue Right (within 12 months of first enrolling in Advantage, if your Advantage plan leaves the market, or in certain other limited situations). California’s Birthday Rule applies only to switching between Medigap plans, not from Advantage to Medigap.
Do I need a Part D prescription drug plan if I have Medicare Supplement?
Yes. Medigap plans do not cover prescription drugs. Without a Part D plan, you pay full retail for prescriptions and accrue a permanent late-enrollment penalty for every month you delay (added to your future Part D premium permanently). The right Part D plan is the one that produces the lowest total cost (premium + copays + tier placement) for your specific medication list — which a broker should rerun every fall during AEP because formularies change annually.
Is Medicare Supplement the same in every state?
The plan benefits are federally standardized (Plan G in California pays exactly what Plan G in Texas pays). But premiums, available carriers, and switching rules vary dramatically by state. California has the consumer-friendly Birthday Rule for annual switches. Most other states require medical underwriting to switch carriers outside the initial enrollment window. This makes California one of the best states in the country for Medigap value over a long retirement.
How do I find a good Medicare Supplement broker in Orange County?
Choose an independent broker (not captive) appointed with at least 8 Medigap carriers and licensed in California with a CDI license number you can verify at insurance.ca.gov. Ask if they call clients every birthday for the Birthday Rule, if they re-review Part D every October, and how they handle claims advocacy. A broker who answers all three questions positively is the one to choose. We Find Your Insurance handles Medigap across all OC ZIPs by phone or video — no in-person meeting required.
When should I sign up for Medicare Supplement?
Ideally, during the six-month Initial Enrollment Period that starts the month you turn 65 and enroll in Medicare Part B. During those six months, every Medigap carrier must sell you any plan they offer with no medical underwriting and no health questions. After that window closes, switching carriers usually requires underwriting (with the exception of California’s Birthday Rule). Delaying Medigap enrollment past the initial window is one of the most expensive Medicare mistakes — develop a condition before you enroll, and many carriers will decline you.
