UnitedHealthcare is one of 7 carriers offering Medicare Advantage in Hawaii for 2027, and the state's carriers together list 46 plans. This article is a plain-English look at what the CMS file shows for UnitedHealthcare specifically. This site is independent — privately owned, not the government and not a carrier.
What is UnitedHealthcare offering across Hawaii for 2027?
UnitedHealthcare is offering 8 Medicare Advantage plans statewide in Hawaii for 2027, and all 8 are PPOs. Of those 8 plans, 6 include Part D prescription drug coverage and 2 do not.
Two of the 8 are Special Needs Plans — specifically, 2 Dual Eligible Special Needs Plans (D-SNPs), which are designed for people who have both Medicare and Medicaid. UnitedHealthcare does not list any Chronic Condition SNPs (C-SNPs) or Institutional SNPs (I-SNPs) in Hawaii for 2027. The full plan-by-plan list, with county reach and drug-coverage status, is rendered as a table on this page.
For context, the CMS 2027 file shows 7 carriers in total offering Medicare Advantage in Hawaii, with 46 plans across all carriers combined.
Which UnitedHealthcare plans reach the most Hawaii counties in 2027?
In Hawaii for 2027, the UnitedHealthcare plans with the widest county reach are the two D-SNPs, UHC Dual Complete HI-Y1 (PPO D-SNP) and UHC Dual Complete HI-YL (PPO D-SNP), each listed in 5 counties. The next widest is AARP Medicare Advantage from UHC HI-5 (PPO), listed in 4 counties.
After those, AARP Medicare Advantage Patriot No Rx HI-MA01 (PPO) is listed in 3 counties, AARP Medicare Advantage from UHC HI-0003 (PPO) in 2 counties, and three plans — AARP Medicare Advantage from UHC HI-0001 (PPO), AARP Medicare Advantage from UHC HI-0002 (PPO), and AARP Medicare Advantage Patriot No Rx HI-MA02 (PPO) — in 1 county each. Hawaii has five counties (Hawaii, Honolulu, Kalawao, Kauai and Maui), and county availability varies plan by plan, so the only reliable way to know what is sold at a specific address is to check Medicare's Plan Finder.
What is new or not returning from UnitedHealthcare in Hawaii for 2027?
For 2027 in Hawaii, UnitedHealthcare has 1 new Medicare Advantage plan and 2 plans from 2026 that are not returning, based on a year-over-year comparison of the CMS Landscape files for 2026 and 2027.
The new 2027 plan is UHC Dual Complete HI-YL (PPO D-SNP), listed in 5 counties. The CMS file does not name the two non-returning plans in this block, but any member whose plan will not be offered in 2027 should receive an Annual Notice of Change (ANOC) and a non-renewal notice from the plan by late September 2026. Those letters explain what happens next and the enrollment windows that apply.
How do I check whether a UnitedHealthcare plan is offered in my Hawaii county and covers my doctors and drugs?
The quickest way to confirm whether a specific UnitedHealthcare plan is offered in your Hawaii county for 2027 — and whether it covers your doctors and prescriptions — is to use the Medicare Plan Finder at medicare.gov or call 1-800-MEDICARE (TTY 1-877-486-2048), available 24 hours a day, 7 days a week.
Enter your ZIP code and county, then your prescriptions and pharmacies. Plan Finder will show which of UnitedHealthcare's 8 Hawaii plans — such as AARP Medicare Advantage from UHC HI-5 (PPO) or UHC Dual Complete HI-Y1 (PPO D-SNP) — are actually offered at your address. To confirm providers, check the plan's own online directory or call the plan; to confirm a specific drug, review the plan's formulary and Evidence of Coverage. This article does not list premiums, copays, benefits, networks, drug lists or star ratings for any plan.
What should Hawaii readers do before December 7, 2026?
Before December 7, 2026, Hawaii readers who want to make a change for 2027 should review their current coverage against their options during Annual Enrollment 2027, which runs October 15 – December 7, 2026. Any choice made in that window takes effect January 1, 2027.
A simple checklist:
- Read the ANOC from your current plan; it describes 2027 changes.
- List your doctors, hospitals, pharmacies and prescriptions.
- Use Plan Finder at medicare.gov to compare plans available in your county.
- If you qualify for both Medicare and Medicaid (QUEST), ask specifically about D-SNPs such as the two UnitedHealthcare lists in Hawaii.
- Keep copies of any confirmation numbers.
If you are satisfied with your current plan and it is returning for 2027, you do not have to do anything to stay enrolled.
Where can Hawaii residents get free help comparing Medicare Advantage plans for 2027?
Hawaii residents can get free, official help comparing 2027 Medicare Advantage plans through Medicare directly: medicare.gov for the Plan Finder and plan documents, and 1-800-MEDICARE (TTY 1-877-486-2048) for live help 24/7.
You can also request each plan's Summary of Benefits and Evidence of Coverage from the carrier itself. Those documents are the authoritative source for premiums, cost sharing, networks and drug coverage — none of which are stated in this article.
