Video Summary: This video explains why network access is one of the biggest practical differences between Medigap and Medicare Advantage, especially if you have doctors you don’t want to give up.
Medicare Advantage plans use narrower networks tied to specific hospital systems — KFF’s national analysis found enrollees have access to roughly half the physicians available to someone on Original Medicare in the same area.

Rising Medicare Supplement premiums catch a lot of Los Altos residents off guard, especially if they’ve stuck with the same carrier for years without comparing options. Because Medigap coverage is standardized, switching carriers for a lower rate doesn’t mean giving up any benefits — Plan G is Plan G no matter who sells it. A Medicare agent serving Los Altos can pull current rates from multiple carriers so you can see whether you’re overpaying for identical coverage.

Video Summary: This video breaks down why Medigap premiums for the exact same plan can rise at very different rates from one carrier to the next, and what that means for shopping around later without medical underwriting getting in the way.

Also asked as: “will Medicare pay for costs related to a clinical trial”
Original Medicare covers routine costs associated with qualifying clinical trials, such as doctor visits and standard tests, even though it doesn’t cover the experimental item or service being studied itself.
Also asked as: “does Medicare make me rent equipment instead of buying it”
For certain types of durable medical equipment, Medicare determines whether the item is rented or purchased based on Medicare’s own equipment classification rules, not personal preference.
Also asked as: “what counts as creditable drug coverage”
Creditable prescription drug coverage means a non-Medicare drug plan, such as one from a current employer, is expected to pay at least as much as standard Medicare Part D coverage.
Also asked as: “does Medicare pay for a dietitian”
Original Medicare covers medical nutrition therapy for people with diabetes or kidney disease when referred by a doctor, typically provided by a registered dietitian.
Also asked as: “should I get a standalone drug plan or Medicare Advantage with drugs included”
A standalone Part D plan is prescription drug coverage added on top of Original Medicare, while a Medicare Advantage plan that includes drug coverage bundles your medical and prescription benefits into a single plan.
Also asked as: “does Medicare pay for a stress test”
Yes — Original Medicare covers medically necessary diagnostic heart screenings, including cardiac stress tests, when ordered by a doctor to evaluate a specific symptom or condition.
CMS sets Medicare Advantage and Part D plan service areas at the county level. Insurance companies decide which counties to offer a plan in based on their own network and cost calculations, which means two people a few miles apart in different counties can have a genuinely different set of plans to choose from — even within the same metro area. Your independent Medicare agent can pull up the specific plans available in your county so you’re comparing your actual options.
Medicare decisions deserve careful planning, whether you’re turning 65, retiring soon, moving to Los Altos, or leaving employer coverage.
