Medicare in Delaware

By July 2024, there were 78,169 Delaware Medicare beneficiaries with Advantage coverage, which was about 32% of the state’s total Medicare population.¹

Nationwide, about 50% of Medicare beneficiaries had Medicare Advantage coverage as of July 2024.⁴ Medicare Advantage enrollment has been increasing steadily since the early 2000s, but Original Medicare remains much more popular in Delaware than it does in many other states, with about 68% of Delaware Medicare beneficiaries opting for Original Medicare.¹

While most eligible Medicare beneficiaries opt into Original Medicare, there is widespread availability of Medicare Advantage plans in Delaware, and residents can choose from among 39 different Medicare Advantage plans for 2025.²

Medicare Advantage enrollment is available when people are first eligible for Medicare benefits, and also during the annual open enrollment period in the fall (October 15 to December 7). During the Medicare Advantage open enrollment period (January 1 to March 31) people who are already enrolled in Medicare Advantage plans can change Medicare Advantage plans or switch to Original Medicare.

Medigap plans are used to supplement Original Medicare, covering some or all of the out-of-pocket costs (for coinsurance and deductibles) that people would otherwise incur if they only had Original Medicare on its own.

There are 39 insurers offering Medigap plans in Delaware for 2025.⁵ The state has a Medigap shopper’s guide that provides a variety of useful information about Medigap plans.

Medigap plans are standardized under federal rules, and people are granted a six-month window, when they turn 65 and enroll in Original Medicare, during which coverage is guaranteed issue for Medigap plans. But federal rules do not guarantee access to a Medigap plan if you’re under 65 and eligible for Medicare as a result of a disability. States can set their own rules, however, and Delaware enacted a law in 2013 that grants a six-month guaranteed issue window for Medigap when people become eligible for Medicare as a result of a disability.

Under the terms of the legislation, Medigap insurers in Delaware that sell plans to people who are 65+ must make all of their plans available to people who are under 65 and enrolled in Medicare due to a disability. But the legislation allows insurers to charge higher premiums for people under age 65, and specifically prohibits insurers from increasing premiums for the 65+ population in order to cover the additional risk involved in providing coverage for disabled Medicare beneficiaries. The legislation requires insurers to have two separate risk pools (and thus separate pricing) for under-65 enrollees who are eligible due to end-stage renal disease (ESRD) versus under-65 enrollees who are eligible due to all other disabling conditions.

But due to this provision, Medigap premiums are dramatically higher for under-65 Delaware residents with ESRD. In many cases, premiums for an under-65 enrollee with ESRD exceed $20,000 per year, while under-65 enrollees without ESRD are generally charged premiums in the range of $4,000 to $7000 per year, and people who are age 65 typically pay somewhere in the range of $1,000 to $2,500 per year (premiums vary considerably from one insurer to another; these ranges cover most plans, but not all of them).

The separate risk pool and sharply higher Medigap premiums for under-65 enrollees with ESRD is particularly important given that prior to 2021, ESRD was also the only condition that prevented a person from enrolling in most Medicare Advantage plans. But starting in 2021, under the terms of the 21st Century Cures Act, people with ESRD are no longer barred from enrolling in Medicare Advantage plans nationwide.

Under federal Medigap rules, all Medicare beneficiaries have a guaranteed-issue open enrollment period when they’re at least 65 years old and enrolled in Medicare Part B. So enrollees in Delaware who are under-65, including those with ESRD, have the option to get a new plan with standard age-65 rates when they turn 65.

Most Medigap insurers in Delaware use attained-age rating, which means that premiums increase as the enrollee gets older. Some insurers use issue-age rating, which means premiums are based on the age the person was when they initially enrolled. United Healthcare/AARP uses community rating (ie, rates don’t vary based on age).

Original Medicare does not cover outpatient prescription drugs. Medicare beneficiaries can get needed prescription coverage via Medicaid,  an employer-sponsored plan, or Medicare Part D — which is available as part of most Medicare Advantage plans or as a stand-alone prescription drug plan (PDP).

As of July 2024, 128,580 of those receiving Medicare benefits in Delaware were enrolled in stand-alone Medicare Part D prescription drug plans.¹ In areas where Medicare Advantage enrollment is lower, enrollment in stand-alone Medicare Part D plans tends to be higher.

For 2025 Medicare Part D enrollment, there are 14 stand-alone Part D plans providing service in Delaware, with monthly premiums starting at $0/month.²

Medicare Part D enrollment is available during the annual open enrollment period in the fall (October 15 to December 7). The plan you select during this window will take effect January 1. It’s recommended that all Medicare beneficiaries review their Part D coverage during open enrollment and consider switching policies if a different plan will better meet their needs (keeping in mind that covered drug lists, in-network pharmacies, and out-of-pocket drug costs can all change from one year to the next, in addition to any changes to a person’s own prescription needs).

Many Medicare beneficiaries receive financial assistance through Medicaid with the cost of Medicare premiums, prescription drug expenses, and services not covered by Medicare – such as long-term care.

Our guide to financial assistance for Medicare enrollees in Delaware includes overviews of these benefits, including Medicare Savings Programs, long-term care coverage, and eligibility guidelines for assistance.
