Navigating Medicare can be complicated, and even small mistakes can lead to higher costs, gaps in coverage, or penalties. Understanding the most common pitfalls and how to avoid them can save you money and ensure you get the healthcare coverage you need.

Mistake 1: Missing Your Initial Enrollment Period (IEP) 

Your Initial Enrollment Period begins 3 months before your 65th birthday month, includes your birthday month, and ends 3 months after.

How to Avoid It 

  • Mark your calendar early and enroll as soon as possible.

  • If you’re still working and have employer coverage, make sure you understand your Special Enrollment Period options to avoid penalties.

Mistake 2: Not Understanding Medicare Parts 

Medicare has multiple parts: Part A (hospital), Part B (medical), Part C (Medicare Advantage), and Part D (prescription drugs). Many people assume enrolling in Part A is enough.

How to Avoid It 

  • Learn which parts you need based on your health, medications, and doctor network.

  • Consider a Medicare Advantage plan if you want bundled coverage or Medigap if you want supplemental coverage.

Mistake 3: Delaying Enrollment in Part B or Part D (H2)

Failing to enroll in Part B or Part D on time can lead to lifetime late enrollment penalties.

How to Avoid It 

  • Check if you qualify for a Special Enrollment Period (SEP) if you’re still working at 65.

  • Keep documentation of your employer coverage to prove creditable coverage.

Mistake 4: Choosing a Plan Without Comparing Costs (H2)

Medicare premiums, deductibles, and copays vary between plans and regions. Choosing the wrong plan can result in unnecessary out-of-pocket costs.

How to Avoid It 

  • Use the Medicare Plan Finder tool to compare costs and benefits.

  • Review your plan annually during the Open Enrollment Period (Oct 15 – Dec 7) to make adjustments.

Mistake 5: Ignoring Prescription Drug Coverage 

Many people assume their Medicare Advantage plan or employer coverage fully covers all prescriptions. Skipping Part D can result in a late enrollment penalty if you ever drop coverage.

How to Avoid It 

  • Check if your medications are on the plan’s formulary before enrolling.

  • Consider a standalone Part D plan if you have specific prescription needs.

Mistake 6: Not Checking Provider Networks (H2)

Some Medicare Advantage plans have restricted networks, meaning your preferred doctors or hospitals may not be covered.

How to Avoid It 

  • Verify your primary care doctor and specialists are in-network before enrolling.

  • If you travel frequently, consider plans with broader networks or nationwide coverage.

Geo-Specific Note on Medicare 

Medicare is federal, but some states have programs that affect coverage:

  • Pennsylvania: Medicare Savings Programs can help pay premiums if income is limited.

  • California: Medi-Cal works alongside Medicare to reduce out-of-pocket costs.

Check your state health insurance assistance program (SHIP) for local resources.

Final Thoughts 

Avoiding common Medicare mistakes ensures you get the coverage you need without paying unnecessary penalties or out-of-pocket costs. Start early, compare plans carefully, and review your coverage annually.

With a little planning, you can navigate Medicare confidently and focus on your health, not your insurance.
