It's the question every Medicare agent faces daily — often before the client has had a chance to finish their sentence: "Should I stay on Original Medicare or switch to Medicare Advantage?" The agents who answer this question well — honestly, thoroughly, and in the client's genuine interest — build careers. The agents who default to whichever pays more build complaints.
As a Gerontologist, I've seen this choice from both sides of the table. Here's the framework I use.
First: Understand What You're Actually Comparing
Original Medicare (Parts A and B) is a federal fee-for-service program. You can see any doctor or specialist in the country who accepts Medicare — no referrals, no network restrictions. Medicare pays its share; you pay yours. The gaps (deductibles, copays, 20% coinsurance with no out-of-pocket maximum) are significant, which is why most people pair it with a Medicare Supplement (Medigap) plan and a standalone Part D drug plan.
Medicare Advantage (Part C) is Medicare delivered through a private insurer approved by CMS. Plans must cover everything Original Medicare covers, but they do so through managed care structures — usually HMO or PPO networks — and they add extra benefits like dental, vision, hearing, and fitness programs. Most have low or $0 premiums. But they come with networks, prior authorizations, and cost-sharing structures that can surprise people who get seriously ill.
The Real Trade-Offs (Not the Oversimplified Version)
✅ Original Medicare + Medigap
- Any doctor nationwide who accepts Medicare
- No referrals or network restrictions
- Predictable costs — Medigap covers most gaps
- Ideal for frequent travelers or snowbirds
- Better for complex or chronic conditions
- No prior authorization for most services
⚠️ Original Medicare + Medigap Downsides
- Higher monthly premiums (Plan G ~$100–$200+/mo)
- Separate Part D premium required
- No dental, vision, hearing included
- Medigap enrollment has underwriting outside OEP
✅ Medicare Advantage
- Low or $0 monthly premium
- Extra benefits (dental, vision, hearing, fitness)
- Annual out-of-pocket maximum protects against catastrophe
- Drug coverage typically included (MA-PD)
- Good choice for healthy beneficiaries with local doctors
⚠️ Medicare Advantage Downsides
- Network restrictions — not all doctors participate
- Prior authorizations for many services
- Plans change annually — benefits, networks, formularies
- Can be problematic for serious illness or surgery
- Coverage outside service area is limited to emergencies
The Question Nobody Asks (But Should)
Here's what I ask every client: "Where do you see yourself in 5 years, and what's your worst-case health scenario?" A healthy 65-year-old with a local primary care doctor and no chronic conditions may do beautifully on a $0 premium Medicare Advantage plan. That same person at 72 with a new cancer diagnosis may desperately wish they had Medigap's freedom to see any specialist anywhere in the country without a prior authorization battle.
What This Means for Your Practice
Agents who understand this distinction serve clients better and retain them longer. An MA client whose plan you review every AEP — adjusting as their health changes, flagging when a switch to Medigap makes sense — is a client who refers everyone they know. That's the practice Darin Weidauer mentors agents to build.
