Understanding Medicare Supplement Plans in Washington for 2025



If you reside in Washington state, supplementing your Original Medicare coverage with a Medigap plan or MA Plan is an option. One such plan, Plan G, administered by Premera Blue Cross, is designed to reduce your out-of-pocket expenses by supplementing services already covered by Medicare. Just bear in mind that this plan may offer limited or no coverage at all for services like vision and hearing exams, along with routine physical exams.

Eligibility for a Medigap plan in Washington requires:

Medigap plans are known for the flexibility they offer, a key benefit. For example, existing Medigap plan members can switch to another plan of the same type (B through N, or A to A) at any time without a health screening questionnaire. Rules may differ if you’re transitioning from another type of health insurance to a Medigap plan, and a written health screening questionnaire might be a requirement.

The Impact of Recent Legislation on Medigap Plans

Medigap plans have been significantly impacted by recent legislation, like the Inflation Reduction Act. The Act includes provisions such as:

  • Lowered drug costs
  • Rebates for price increases over inflation
  • A monthly cap on insulin costs
  • Cost-sharing elimination for adult vaccines

All of these can help ease the financial burden on Medigap policyholders by addressing average benchmark payments.

The Act, starting in 2024, introduced a cap on out-of-pocket costs for Medicare Part D, initially removing the 5% coinsurance above the catastrophic coverage threshold. By 2025, a hard cap of $2,000 on out-of-pocket spending will be established, which may further reduce expenses for those with Medigap policies.

Moreover, wider legislative changes have taken place. For instance, in 2024, eligibility for the Medicare Part D Low-Income Subsidy was expanded and the delayed implementation of the Trump Administration’s drug rebate rule until 2032 could potentially affect Medigap plan costs and coverage. These changes were made under the Biden administration as part of the government’s phased-in healthcare reforms, which also include the continued phase-in of other measures, such as the proposed rule and proposed rules released.

Navigating Changes to Medicare Advantage and Part D

Medicare Supplement Insurance plans can be directly affected by changes to Medicare Advantage and Part D. The CMS-HCC risk adjustment model, which aims for accurate Medicare payments, is currently being implemented by the Centers for Medicare and Medicaid Services (CMS). Changes to this risk adjustment and updates to models in 2025 may lead to shifts in the Medicare Supplement Insurance market, particularly for Medicare Advantage insurers. Understanding the Medicare Advantage insurers code can be crucial for navigating these changes.

Furthermore, a technical adjustment in 2025 to how Medicare costs related to medical education are calculated could potentially affect the cost and structure of Medicare Supplement Insurance plans. With the slight proposed cut, proposals to increase payments from the government to 2025 Medicare Advantage plans by an average of 3.70 percent could influence the landscape of Medicare Advantage and possibly the pricing and benefits of Medicare Supplement Insurance plans.

CMS is also making changes to Medicare Part D drug benefits to lower prescription drug costs. These changes, including no cost-sharing in the catastrophic phase and a $35 cap on insulin, may influence the value proposition of Medicare Supplement plans that offer prescription drug coverage.

How to Choose the Right Medigap Plan in 2025

To choose the right Medigap plan, follow these steps:

  1. Compare the benefits of each lettered plan while considering your current and anticipated healthcare needs.
  2. Select a policy from a state-licensed insurance company.
  3. Ensure the policy is clearly labeled as ‘Medicare Supplement Insurance’.

By following these steps, you can make an informed decision about which Medigap plan is best for you.

Not all Medigap plans are offered in every state, and not all insurance companies sell policies for each plan. Thus, it’s advisable to confirm availability with the insurance companies. Remember, price distinguishes Medigap policies from the same letters sold by different companies. As such, shopping based on price and comparing costs from different insurers is crucial.

Make sure to:

  1. Obtain an official quote from the insurance company
  2. Thoroughly read the summary of the Medigap policy before making a purchase
  3. Confirm that your policy takes effect as desired, providing advance notice if necessary
  4. Contact the insurance company if you do not receive the policy or proof of insurance within 30 days.

Staying Informed: Resources and Support for Washington Residents

In Washington, the waiting period for pre-existing conditions for Medigap enrollees is limited to three months, offering quicker coverage than the federal limit of six months. Furthermore, the state requires Medigap premiums to be consistent for enrollees 65 and older, regardless of individual health status, through community rating by age.

However, as Medigap insurers in Washington are not obligated to offer coverage to under-65 Medicare enrollees due to disability, these individuals may face coverage challenges related to their health conditions. In such cases, the Washington State Health Insurance Pool (WSHIP) provides an essential high-risk pool option for disabled Medicare beneficiaries unable to secure Medigap coverage due to medical underwriting. The WSHIP Medical Supplement Plan ensures guaranteed-issue supplemental coverage for those without Medicare Advantage plan options or with end-stage renal disease.

State law empowers Washington Medigap policyholders to switch plans at any time on a guaranteed-issue basis, a benefit extending beyond federal enrollment periods established by the federal government. For assistance in selecting an insurance company or to address complaints, Washington residents can contact the State Insurance Department and local SHIP.
