A Seniors Guide article identifies five Medicare decisions that can lead to higher costs: failing to review Part D coverage, choosing a spouse’s plan by default, using out-of-network care, missing plan-change windows and delaying Medigap selection. The article describes general risks; actual costs and enrollment rights depend on an individual’s plan, location and circumstances.

Seniors Guide has published a report describing five Medicare plan and enrollment mistakes that can expose beneficiaries to higher premiums, out-of-pocket expenses or gaps in coverage. The article focuses on reviewing prescription drug coverage, checking Medicare Advantage networks, using available enrollment periods and choosing Medigap coverage with state rules in mind.

The report advises people with Medicare Part D or Medicare Advantage coverage to review their options during the annual enrollment period, which it gives as Oct. 15 to Dec. 7. A plan’s premiums, drug costs, coverage requirements and preferred pharmacies can change, while a beneficiary’s prescriptions may change too. Seniors Guide recommends comparing plans with the Medicare Plan Finder, entering medications and dosages to estimate premiums and cost-sharing.

It cautions spouses against assuming they should enroll in the same Part D plan. The report says there are no spousal discounts and that each person’s prescriptions may be covered differently. It also flags pharmacy networks: a plan may offer its best rates only at preferred pharmacies, so separate plans could mean using different locations to keep costs down.

For Medicare Advantage members, the article says doctors, hospitals and pharmacies should be checked against the plan’s network each year. It lists two recurring chances to change coverage: the annual period from Oct. 15 to Dec. 7 and the Medicare Advantage open enrollment period from Jan. 1 to March 31. It also discusses limited special enrollment opportunities and the report’s stated option to switch to a five-star Medicare Advantage plan during the year. On Medigap, it says the six-month period after enrollment in Medicare Part B generally provides a protected opportunity to buy a plan, while later applications may face health-based restrictions in many states.

How Plan Choices Affect Medicare Costs

The practical issue is that Medicare coverage is not a single fixed package: plans can differ in premiums, drug coverage, provider networks and cost-sharing. A beneficiary who does not compare options may keep paying for a plan that no longer fits their prescriptions or preferred providers. Conversely, changing plans without checking details can create unexpected expenses if a medication, pharmacy or clinician is treated differently under the new coverage.

Enrollment timing can also matter. Missing a relevant deadline may restrict when someone can change coverage, and Medigap access can depend on federal protections and state-specific rules. The report’s central point is to check the actual plan terms and personal eligibility rather than assuming last year’s choice remains suitable. Its recommendations are general information, not a guarantee that switching will lower costs.

The Enrollment Windows Behind the Advice

The article presents five potential mistakes: leaving Part D on autopilot, choosing the same drug plan as a spouse without comparing needs, receiving non-emergency care outside a Medicare Advantage network, failing to use an available plan-change period, and selecting Medigap without considering later enrollment restrictions.

Its dates refer to recurring Medicare enrollment windows, not a newly announced change to Medicare policy. Seniors Guide points readers to the Medicare Plan Finder for plan comparisons and to state insurance departments for local Medigap rules. Plan availability and protections can vary by location, and the report directs readers to Medicare.gov for additional Medigap information.

““The cost and coverage can vary a lot from year to year.””

Individual Costs and State Rules Vary

The report does not calculate savings or costs for a particular beneficiary, and it does not establish that switching plans will reduce anyone’s expenses. Actual premiums, covered drugs, network rules and cost-sharing depend on the plan and location. It also does not detail every exception to enrollment rules, Medigap protections or special enrollment eligibility. The availability of a five-star plan and the rules for changing to one should be checked for the individual’s area and circumstances.

Because state Medigap rules differ, the article’s description of protections after the initial six-month period should not be treated as uniform nationwide. Beneficiaries should confirm current rules with Medicare, their insurer or their state insurance department before making a coverage decision.

Check Coverage Before Deadlines

People reviewing coverage can compare plans during the applicable enrollment period, using their current medications, dosages, doctors and preferred pharmacies. The report recommends confirming network participation with both the insurer and the health care provider, since online listings may not resolve every question about next year’s coverage.

Those considering a Medigap change can check state rules and available policies through their state insurance department and Medicare.gov. Anyone unsure whether a special enrollment period applies should verify eligibility with Medicare or the plan before ending existing coverage. The next step for each reader depends on their coverage and circumstances; the report does not identify a new policy deadline beyond the recurring dates it lists.

Key Questions

When can Medicare beneficiaries review or change plans?

The report gives Oct. 15 to Dec. 7 as the annual enrollment period. It also gives Jan. 1 to March 31 as the Medicare Advantage open enrollment period, when eligible Medicare Advantage members may make certain changes. Confirm which actions are available for your coverage with Medicare or your plan.

Should spouses choose the same Part D plan?

Not automatically. The report says there are no spousal discounts and that each person’s prescriptions may be covered differently. Compare each person’s medications, costs and pharmacy options separately.

Why check a Medicare Advantage provider network each year?

Doctors, hospitals and pharmacies may not be included in every plan’s network. The report says out-of-network care may cost more or have limited coverage, depending on the plan and circumstances. Confirm participation with both the insurer and the provider.

Can someone change Medicare Advantage coverage outside the usual periods?

Sometimes. The report describes limited special enrollment circumstances, including moving outside a plan’s service area, and says a five-star plan may be available as another route. Eligibility and plan availability must be checked for the individual’s location and situation.

Can a person switch Medigap plans at any time?

Not necessarily. The report says the six months after enrolling in Part B generally provide a protected opportunity to buy a Medigap plan, while later applications may be subject to health-based restrictions in many states. State protections vary, so check local rules before applying or dropping coverage.
