Medicare under 65 in Hawaii — disability, ESRD, and ALS

Medicare isn't just for people 65 and older. Hawaii residents under 65 can qualify for Medicare through specific pathways: Social Security Disability, end-stage renal disease, or amyotrophic lateral sclerosis (ALS). The rules differ from age-65 enrollment in important ways.

Three pathways to Medicare under 65

Medicare via Social Security Disability

The most common path to Medicare under 65 is qualifying for Social Security Disability Insurance (SSDI). Eligibility requirements:

• Have a medical condition that meets Social Security's definition of disability
• Have enough work credits — typically 40 quarters, with at least 20 of those in the last 10 years
• Be unable to do substantial gainful activity due to your condition
• Your disability must have lasted (or be expected to last) at least 12 months, or result in death

The 24-month waiting period

For most SSDI recipients, Medicare starts 24 months after SSDI benefits begin. This is one of the hardest rules in Medicare:

• SSDI itself has a 5-month waiting period from when you become disabled
• Then there's an additional 24-month waiting period before Medicare starts
• Total time from disability onset to Medicare can be 29 months
• During that time, you typically need other coverage — Marketplace, Med-QUEST, employer coverage, COBRA, or family insurance

This waiting period creates real hardship for many disabled Americans. Hawaii has resources to help bridge the gap.

Bridging the waiting period in Hawaii

• Med-QUEST — many disability beneficiaries qualify based on income; this is the most common bridge
• Hawaii Health Connector / ACA Marketplace — subsidized coverage based on income
• Continuation of employer coverage — short-term and long-term disability insurance often includes health benefits
• COBRA — extends employer coverage up to 18 months (or 29 months if disabled within 60 days of starting COBRA)
• Family member's plan — if you can be added as a dependent
• Federally Qualified Health Centers — sliding-scale care during gaps

What Medicare looks like under 65

Medicare under 65 is essentially the same as Medicare at 65:

• Part A — typically free if you qualify by SSDI work history
• Part B — same premium ($202.90/month in 2026)
• Part D — same prescription coverage
• Medicare Advantage — same plan options as 65+ enrollees
• Medigap — important caveat below

Medigap and under-65 Medicare in Hawaii

This is where things get more complicated. Federal law does NOT require insurers to sell Medigap policies to under-65 Medicare beneficiaries. Each state sets its own rules.

Hawaii does not require Medigap insurers to sell to under-65 beneficiaries. As a result:

• Medigap may not be available, or
• Available only at significantly higher premiums, or
• Available only with medical underwriting (could be denied or rate-up based on health)

For Hawaii under-65 beneficiaries, Medicare Advantage is often the more practical choice because plans must accept you regardless of health.

When you turn 65, you get a new 6-month Medigap Open Enrollment Period — at that point, you have full guaranteed-issue rights regardless of health. Many under-65 Medicare beneficiaries wait until 65 to add Medigap.

Medicare and Med-QUEST for disabled Hawaii residents

Many disabled Hawaii residents qualify for both Medicare and Med-QUEST (dual-eligibility), which provides:

• Med-QUEST pays Medicare premiums and cost-sharing
• Extra Help dramatically reduces prescription costs
• D-SNPs offer integrated coverage
• Med-QUEST covers benefits Medicare doesn't (long-term care, transportation, etc.)

If you're under 65 with Medicare, also apply for Med-QUEST if you might qualify. See our Med-QUEST guide.

Medicare for ALS

People with ALS (Lou Gehrig's disease) get expedited Medicare:

• No 24-month waiting period — Medicare starts the same month SSDI starts
• SSDI's 5-month waiting period also does not apply for ALS
• This recognizes the rapid progression of ALS
• If diagnosed with ALS, apply for SSDI immediately — Medicare follows automatically

Working while disabled — keeping Medicare

If you start working while on disability Medicare, special rules let you keep Medicare:

• Trial Work Period — 9 months of testing work without losing benefits
• Extended Period of Eligibility — 36 months after Trial Work Period; SSDI continues if income stays below substantial gainful activity
• Continued Medicare — at least 93 months after Trial Work Period (about 7.5 years)
• Medicare for People with Disabilities Who Work — option to continue paying for Medicare after that

These work incentive programs are designed to encourage disabled people to attempt work without losing Medicare too quickly.

Practical advice for under-65 Medicare beneficiaries

1. Apply for Med-QUEST alongside Medicare — dual-eligibility provides comprehensive coverage
2. Apply for Extra Help — caps prescription costs dramatically
3. Compare Medicare Advantage carefully — for under-65 in Hawaii, often a better fit than Original Medicare without Medigap
4. Plan ahead for 65 — your Medigap Open Enrollment at 65 is a unique opportunity
5. Keep documentation of disability and work history — important for appeals and benefit transitions
6. Connect with Sage PLUS — free counseling specifically helpful for complex under-65 situations
