7 Mistakes DFW Seniors Make During Medicare Open Enrollment

Every fall, Medicare’s Annual Open Enrollment Period (running from October 15 to December 7) offers Dallas–Fort Worth seniors a vital opportunity to make or update their Medicare coverage choices. Missing this window or making avoidable mistakes can lead to higher costs, coverage gaps, or denied benefits.

Let’s cover the top missteps DFW residents often make, and how to sidestep them confidently.

Mistake 1: Assuming Your Plan Stays the Same

Many seniors assume that since they were enrolled last year, everything will stay the same. But Medicare Advantage, Part D, and Medicare Supplement plans can change annually: in benefits, premiums, formularies, and provider networks.

How to Avoid It: Review your Annual Notice of Change or plan materials by September 30. Compare how benefits, costs, and providers stack up for 2026 before deciding.

Mistake 2: Missing the Open Enrollment Window

Skipping the October 15–December 7 window typically means waiting an entire year to switch plans, unless you qualify for a Special Enrollment Period.

How to Avoid It: Mark calendar reminders now. Even if your current plan seems fine, comparing options can reveal big savings.

Mistake 3: Overlooking Prescription Plan Changes

With the new $2,000 annual out-of-pocket Part D cap, formularies and copays are shifting in 2026. Failing to review your Part D or Advantage drug coverage may lead to surprise costs or interruptions.

How to Avoid It: Check that your medications are still covered and compare your plan’s deductible, tiers, and drug cap details right when Open Enrollment opens.

Mistake 4: Choosing Based Only on Premium

A low or $0 premium may look attractive, but may come with higher copays, restrictive networks, or limited coverage.

How to Avoid It: Look at total costs, including out-of-pocket limits, provider access, benefits like dental and vision, and prescription coverage, not just the premium.

Mistake 5: Ignoring Changes in Provider Networks

Some Medicare Advantage plans tweak their networks yearly. If your preferred doctor is dropped, you might be forced to change providers.

How to Avoid It: Always confirm that your primary care physician and specialists will remain in-network for 2026 before selecting a plan.

Mistake 6: Waiting Too Late to Make a Switch

Delaying your research until mid-December can leave you rushed, at risk of missing deadlines, or defaulting to your current plan.

How to Avoid It: Start comparing plans in milestones: mid-September for premium notices, early October for plan comparisons, and finalize by early December.

Mistake 7: Neglecting Financial Impacts of IRMAA and Premium Increases

Medicare Part B and D premiums may inch higher in 2026, and retiree income changes could trigger IRMAA surcharges.

How to Avoid It: Review your income brackets and consider strategic financial moves (like Roth conversions) to limit IRMAA penalties.
