Medicare enrollment in Arkansas
As of early 2026, there were 689,868 Arkansas residents enrolled in Medicare.1 Medicare enrollment happens for most Americans when they turn 65 – either automatically, if they’re already receiving Social Security or Railroad Retirement benefits, or during a seven-month enrollment window when they can complete the process of filing for Medicare benefits.
But Medicare eligibility is also triggered for younger people if they’re disabled and have been receiving disability benefits for 24 months, or if they have amyotrophic lateral sclerosis amyotrophic lateral sclerosis (ALS) or end-stage renal disease (ESRD).
Nationwide, more than 90% of Medicare beneficiaries are eligible due to their age, while about 9% are eligible due to a disability.2 In Arkansas, about 15% of the people with Medicare are eligible due to disability rather than age.3

Medicare supplement (Medigap) enrollment and regulations in Arkansas

Learn more about Medigap plans, including what they cover and how they’re standardized under federal rules.
Arkansas is one of just nine states9 where Medigap premiums cannot vary based on an enrollee’s age,10 as long as the enrollee is at least 65 years old (more on this below). Medigap premiums in Arkansas can still vary based on tobacco use and medical history, with preferred premiums and standard premiums for various scenarios.
There are 24 insurance companies that offer Medigap plans in Arkansas.11 Medigap insurers in the state are required to maintain minimum loss ratios of at least 65% for individual policies, and at least 75% for employer group policies. This means that at least 65% (or 75% for group plans) of the premium revenue that the insurers bring in must be spent on enrollees’ healthcare claims.
People who aren’t yet 65 can enroll in Medicare if they’re disabled and have been receiving disability benefits for at least two years or if they have amyotrophic lateral sclerosis (ALS) or kidney failure, and about 15% of Arkansas Medicare beneficiaries are under age 65.12 Federal rules do not guarantee access to Medigap plans for people who are under 65, but the majority of the states have implemented rules to ensure that disabled Medicare beneficiaries have at least some access to Medigap plans.
Arkansas joined them in 2018, with a law that was enacted in 2017 (Act 684). The law called for the Arkansas Insurance Department to amend the state’s rules so that people under age 65 would be able to purchase Medigap coverage by 2018. (Prior to that, Medigap insurers in Arkansas did not have to sell plans to people under the age of 65.)
Since July 2018, Medigap insurers must offer at least one Medigap plan to Medicare beneficiaries under the age of 65.13 Insurers can pick which plan they want to offer to disabled enrollees, and nearly all of them have chosen Plan A (the least comprehensive Medigap plan), although Arkansas Blue Cross Blue Shield also offers other options.14
There is no requirement that Arkansas Medigap insurers extend the “no age rating” rule to people under the age of 65, and most of the insurers charge significantly higher premiums for disabled enrollees.14
Disabled Medicare beneficiaries have another Medigap open enrollment period when they turn 65. At that point, they can pick from any available plan, and with the lower premiums that apply to people who are age 65.
