HMSA Medicare Plan Changes: 2027 Guide for Seniors

Introduction: A Major Medicare Shift for Hawaii Seniors

A letter arriving in your mailbox this fall could mean more than routine paperwork. HMSA has announced it will discontinue its Medicare Advantage plan, a change expected to affect roughly 16,000 members across the Hawaiian Islands, according to HMSA's plan non-renewal notice filed with the Hawaii Insurance Division and CMS.

The timing matters. Medicare's annual open enrollment period runs each fall, and this year it carries extra weight for anyone whose current coverage is ending. Decisions made in the coming weeks will shape your access to doctors, prescriptions, and medical costs throughout 2027.

This article walks through what is actually happening with HMSA's Medicare plans, why the terminology can feel overwhelming, and what steps help you compare your options clearly. By the end, you will have a practical path forward rather than a pile of unanswered questions.

What Is Happening With HMSA's Medicare Plans

HMSA has confirmed it is discontinuing its affected Medicare Advantage plan, with coverage ending December 31, 2026. Members should check their non-renewal notice for the exact plan name and H-number listed for their coverage, as this identifies precisely which plan is being discontinued. Affected members will need to select new coverage to avoid a gap starting January 1, 2027.

HMSA has not publicly detailed every business reason behind the decision, and speculating would not serve you well here. What matters is the practical outcome: your current plan will not be available next year, regardless of the cause.

Affected members should be receiving a formal non-renewal notice by mail. This notice outlines your coverage end date and confirms that you qualify for a Special Enrollment Period to choose new coverage without penalty.

Why Medicare Terms and Plan Types Can Feel Confusing Right Now

Medicare Advantage, Medicare Supplement, and Original Medicare are not interchangeable terms, even though they often get lumped together. Original Medicare, administered by the federal government, covers hospital care under Part A and outpatient care under Part B. Medicare Advantage plans, offered by private insurers like HMSA, bundle those benefits together, often with extra coverage like prescriptions.

Medicare Supplement, also called Medigap, works differently. It pairs with Original Medicare to help cover deductibles and coinsurance rather than replacing your benefits entirely.

When a plan ends mid-cycle, confusion tends to spike. You might wonder whether you are starting fresh or simply switching carriers, and whether your new plan type changes how your care gets managed. Understanding these basic categories first makes every comparison afterward much simpler.

Understanding the Real Costs Behind This Change

Losing a Medicare Advantage plan can shift more than just your monthly premium. Copays, deductibles, and your annual out-of-pocket maximum can all look different under a new plan, even one that seems similar on paper.

For 2026, Medicare Advantage plans that use an in-network-only out-of-pocket maximum are capped at $9,250, according to CMS.gov, while plans that count both in-network and out-of-network costs toward the limit are subject to a higher combined cap. Individual plans can set lower limits than either maximum. A new plan's advertised premium might be lower than what you paid with HMSA, but that number alone does not tell the full story.

A plan with a lower premium can carry higher copays for specialist visits, imaging, or hospital stays, which adds up quickly if you need regular care. Before enrolling, ask how much you would pay for a typical doctor visit, a hospital admission, and your current prescriptions under each plan you are considering.

💡 Eddie's Pro Tip

I always tell people to run the numbers on a bad year, not just a healthy one. If you ended up in the hospital or needed a specialist three times, which plan would actually cost you less? That question usually reveals more than comparing premiums side by side.

Will Your Doctors and Prescriptions Still Be Covered

One of the biggest worries when a plan ends is whether you can keep seeing the same doctors. Start by calling your physician's office directly and asking which Medicare plans they currently accept, since provider directories are not always current.

Next, check each new plan's formulary, which is the list of covered prescription drugs, for every medication you take regularly. Formularies place drugs into cost tiers, so a medication can technically be covered yet still cost significantly more depending on its tier placement.

Consider this scenario: a retired teacher on Oahu takes three maintenance medications and sees a cardiologist twice a year. Before switching plans, she calls her cardiologist's office, confirms network participation, and checks all three drugs against two plan formularies, catching a tier difference that would have cost her hundreds more annually.

Verifying this information before your current coverage ends gives you time to resolve any gaps, rather than discovering a problem at the pharmacy counter in January.

Avoiding Enrollment Deadlines, Penalties, and Costly Mistakes

Medicare's standard annual open enrollment period runs from October 15 to December 7, giving most beneficiaries a window to switch plans for the coming year, according to the <a href="https://www.medicare.gov/basics/get-started-with-medicare/get-more-coverage/joining-a-plan">Medicare.gov enrollment guidance</a>. Because HMSA's plan termination counts as an involuntary loss of coverage, affected members also qualify for a Special Enrollment Period, which offers added flexibility beyond that standard window.

This Special Enrollment Period generally allows you to enroll in a new Medicare Advantage plan, a standalone Part D plan, or switch to Original Medicare with a Medigap policy, without facing the late enrollment penalties that normally apply.

Missing your enrollment deadline is the scenario to avoid most. Without new coverage in place, you could face a gap where routine care and prescriptions are not covered at all starting January 1, 2027.

Getting Help You Can Trust Without Feeling Pressured

A licensed Medicare agent should walk you through your options in plain language, explain the tradeoffs, and let you ask questions at your own pace. If a conversation feels rushed or focused on a single product, that is a signal to look elsewhere.

Transparent comparison tools that show plan costs, networks, and drug coverage side by side can help you evaluate choices objectively. Genuine client reviews also offer insight into how an agent or organization actually communicates, beyond marketing language.

Taking a step-by-step approach, confirming your doctors, checking your prescriptions, and comparing total costs, builds confidence before you sign anything. You do not need to make this decision in one sitting, and a trustworthy source will never ask you to.

Frequently Asked Questions About the HMSA Medicare Plan Changes

Conclusion: Moving Forward With Confidence

HMSA's decision to discontinue its Medicare Advantage plan is a significant shift, but it does not have to mean uncertainty about your care. Confirm your coverage end date, verify your doctors and prescriptions, and compare total costs across your available options.

Help is available if you want a second set of eyes on your comparison, and you can move through this process one step at a time. Acting early, rather than waiting until the final days of open enrollment, is the clearest way to avoid a gap in coverage or an unwelcome cost surprise in 2027.
