Medicare Supplement Cost in Honolulu, HI

Medicare Supplement (Medigap) Plan G in Honolulu, Hawaii costs approximately $165/month for a 65-year-old non-smoker — this is the Hawaii state rate, as Medigap premiums are regulated at the state level. Plan N costs about $130/month. Hawaii rates are 11% above the national average of $148/month for Plan G. Always compare quotes from 3+ insurers — rates vary 20–40% for identical plans.

For most Honolulu residents enrolling in Medicare after January 1, 2020, Plan G is the most comprehensive option available. Plan G covers everything Medicare leaves behind except the Part B deductible ($283/year in 2026). Plan N is similar but adds copays up to $20 for doctor visits and $50 for ER visits, saving $35/month vs. Plan G. If you rarely visit the doctor, Plan N may be more economical.

The best time to enroll is during your 6-month Medigap Open Enrollment Period — it starts the month you turn 65 AND are enrolled in Medicare Part B. During this window, Hawaii insurers cannot deny coverage or charge more for pre-existing conditions. After this window, medical underwriting applies in most states, and you may be denied or face higher premiums. Hawaii does not have extended guaranteed-issue protections, making timely enrollment especially important.

Plan G in Honolulu costs approximately $1980/year in premiums. Without Medigap, you'd face: no out-of-pocket maximum on Medicare Part B (20% of all services, unlimited), a $1,762 Part A deductible per hospitalization in 2026, and $400/day skilled nursing copay for days 21–100. One serious hospitalization can easily cost $10,000–$30,000 in Medicare gaps. For Honolulu residents with any significant health needs, Plan G often pays for itself within 1–2 hospital stays.

All Plan G policies offer identical benefits by federal law — the only difference between insurers is price.
