Medicare Supplement Plans &
Medical Alert Systems Guide
Plain-English guidance on Medigap plans, state-by-state pricing, and top-rated medical alert devices — written for seniors and their families, not insurance insiders.
Medicare Supplement Plans
Medicare Supplement plans — also called Medigap — are sold by private insurance companies to fill the gaps in Original Medicare coverage. There are 11 standardized plans (A through N), and the benefits of each plan are identical regardless of which insurer you buy from. The only variables are the monthly premium and the insurance company's financial strength and customer service.
Plan G is currently the most popular plan for new enrollees. It covers virtually everything Medicare doesn't — except the annual Part B deductible ($257 in 2026). Most people pay a single predictable premium and face minimal out-of-pocket costs for the entire year.
Plan N is the second most popular choice. It has lower monthly premiums than Plan G in exchange for small copayments (up to $20 for some doctor visits, up to $50 for emergency room visits that don't result in admission).

Medical alert systems — also called personal emergency response systems (PERS) — allow seniors to quickly call for help in a medical emergency. A small, wearable button connects you to a 24/7 monitoring center that can dispatch emergency services, family members, or neighbors.
Modern systems go far beyond the classic "I've fallen and I can't get up" button. Today's devices include automatic fall detection (no button press needed), GPS tracking for seniors who are active outside the home, two-way voice communication, and caregiver apps for remote monitoring by family members.
Monthly costs range from $20 to $55 depending on features. No long-term contracts are required from reputable providers.

Understanding Medicare's Coverage Gaps
Original Medicare covers a lot, but it doesn't cover everything. Here are the key gaps that Medicare Supplement plans are designed to fill:
Part A (Hospital) Gaps
- Hospital deductible: $1,676 per benefit period in 2026. You could owe this multiple times per year if hospitalized more than once.
- Extended hospital stays: After day 60, you pay $419/day; after day 90, $838/day.
- Skilled nursing facility: $209.50/day after day 20.
Part B (Outpatient) Gaps
- Annual deductible: $257 in 2026, paid once per year before Medicare kicks in.
- 20% coinsurance: Medicare pays 80% of outpatient costs; you pay the other 20% — with no cap.
- Excess charges: Doctors who don't accept Medicare assignment can charge up to 15% more than the Medicare-approved amount.
Medicare Supplement Costs Vary Significantly by State
Plan G premiums for a 65-year-old can range from around $100/month in Mississippi to over $280/month in New York. This variation is driven by state rating laws (attained-age vs. community rating), local healthcare costs, and the number of insurers competing in your state.
Three states — California, Connecticut, and New York — use community rating, which means every enrollee pays the same premium regardless of age. This benefits older beneficiaries but makes plans more expensive at age 65.
California and Florida have Birthday Rules that allow you to switch Medigap plans annually without medical underwriting — a valuable consumer protection.

Frequently Asked Questions
What is the difference between Medicare Supplement and Medicare Advantage?
Medicare Supplement (Medigap) plans work alongside Original Medicare (Parts A & B) to cover your cost-sharing — deductibles, copays, and coinsurance. Medicare Advantage (Part C) is an alternative to Original Medicare offered by private insurers and often includes additional benefits like dental and vision. They are fundamentally different approaches to Medicare coverage and cannot be combined.
When is the best time to buy a Medicare Supplement plan?
The best time is during your 6-month Open Enrollment Period, which begins the month you turn 65 and are enrolled in Medicare Part B. During this window, insurance companies cannot deny you coverage or charge higher premiums based on your health. Outside this window, insurers can medically underwrite your application in most states.
Does Medicare cover medical alert systems?
Original Medicare (Parts A and B) does not cover personal emergency response systems (medical alert devices). Some Medicare Advantage plans include this benefit — check your specific plan. Medicaid may cover them for eligible beneficiaries in some states.
What is the most popular Medicare Supplement plan?
Plan G is currently the most popular Medicare Supplement plan for new enrollees, as of 2024–2026. It covers nearly everything except the annual Part B deductible ($257 in 2026). Plan N is the second most popular, offering lower premiums in exchange for small copayments.
How much does a medical alert system cost per month?
Medical alert systems typically cost between $20 and $55 per month depending on features. Basic in-home systems start around $20/month. GPS mobile systems with nationwide coverage run $30–$45/month. Systems with automatic fall detection typically add $10/month. None require long-term contracts from reputable providers.
