Medicare Planning Guide

Medicare in one sentence

Medicare is a federal health insurance program primarily for people age 65 and older (and some younger individuals with qualifying conditions). The choices you make determine how you receive care, what you pay out of pocket, and how prescriptions are covered.

Medicare Parts A and B: “Original Medicare”

Original Medicare is the combination of Part A and Part B. Many people start here because these are the core building blocks.

Part A (hospital insurance)

Part A generally relates to inpatient hospital care, skilled nursing facility care (under certain conditions), hospice, and some home health care. Many people qualify for premium-free Part A based on work history, but costs can still exist through deductibles and coinsurance.

Part B (medical insurance)

Part B generally relates to doctor services, outpatient care, preventive services, and some medical equipment. Part B typically has a premium, and timing matters—enrolling late can lead to penalties depending on your situation.

Part D: prescription drug coverage

Part D helps cover prescription drugs and is offered through private plans approved by Medicare. Formularies (drug lists), pharmacy networks, and tiers all affect what you pay. Because people’s medications and needs change, Part D is one of the areas where an annual review can be valuable.

Part C: Medicare Advantage

Medicare Advantage (Part C) is an alternative way to receive your Medicare benefits through a private plan. These plans often include additional features and may bundle Part D drug coverage. Plan structures and networks vary.

A Medicare Advantage plan may be appealing for people who prefer a single plan structure and are comfortable using the plan’s network and rules. The tradeoffs are important: how referrals work, whether out-of-network care is covered, and how cost-sharing is structured for services.

Medigap: supplemental coverage paired with Original Medicare

Medigap (Medicare Supplement Insurance) is designed to work alongside Original Medicare to help reduce certain out-of-pocket costs. Instead of replacing Original Medicare, it “supplements” it. This can be especially helpful for people who value predictability and flexibility in provider access (depending on plan type and availability).

Many Medicare strategies come down to choosing between:

• Original Medicare + Medigap + Part D (separate pieces, often more flexibility)
• Medicare Advantage (Part C) (one plan structure, often network-based)

Enrollment timing: why planning ahead matters

Medicare has specific enrollment windows. Missing them can create late enrollment penalties or gaps in coverage. While the exact rules depend on your situation (especially if you’re working past 65 or have employer coverage), the core principle is consistent: timing and coordination matter.

If you’re approaching 65, it’s wise to start planning a few months early so you can:

• Understand how your current coverage transitions
• Compare plan structures and costs
• Confirm prescriptions and providers are handled appropriately
• Avoid preventable penalties or coverage gaps

How to choose between Medicare Advantage and Medigap

There’s no universal “best” choice. The right structure depends on how you use care, your budget preferences, and how much flexibility you want. Consider these decision points:

1) Provider access and travel

If you value broad access to providers or travel frequently, network structure and out-of-network rules matter. Some people want maximum flexibility; others are comfortable using a local network.

2) Predictability vs. pay-as-you-go

Some structures emphasize predictable monthly premiums with fewer surprises; others have lower monthly costs but higher cost-sharing when you use services. The right answer depends on your comfort with variability.

3) Prescription needs

Your medications can significantly influence which plan is the best fit. Formularies, preferred pharmacies, and authorization rules can change costs.

4) Long-term planning

Medicare isn’t a one-time decision; it’s an ongoing plan. Annual reviews can help ensure the coverage still fits your health needs, budget, and provider access.

Common Medicare mistakes we help clients avoid

• Waiting too long to plan: missing enrollment windows can create penalties or gaps.
• Assuming all plans are the same: networks, drug lists, and cost-sharing rules vary.
• Not checking prescriptions: a plan that looks good can be expensive if key medications aren’t handled well.
• Not reviewing annually: plan details can change year to year, and so can your needs.

What to gather before a Medicare review

To make a Medicare review efficient, it helps to have:

• A list of prescriptions (name, dosage, frequency)
• Preferred pharmacies
• Preferred doctors/providers and where you receive care
• Any current coverage details (employer coverage, retiree coverage, or marketplace plans)
