For most people in Sumner whose Medicare Advantage plan is leaving, the thing that breaks first on January 1 isn't the doctor. It's the pharmacy counter. In Pierce County, 86,770 of the 91,398 people in Medicare Advantage and other health plans get their drug coverage through that plan (CMS, July 2026). When the plan stops on December 31, 2026, the prescriptions coverage stops with it. So this page starts with drugs.
Three ways your drug coverage can look on January 1, 2027
- You joined another Medicare Advantage plan with drug coverage by December 31. Your new plan's formulary and pharmacy network apply from January 1. Check, before joining, that your medications are on its 2027 list and that your usual pharmacy is in network.
- You moved to Original Medicare and picked a stand-alone Part D plan by December 31. The drug plan starts January 1 alongside Parts A and B. Same homework: your drugs, your pharmacy.
- You did nothing. Medicare puts you in Original Medicare on January 1, and you have no drug plan at all, unless you get Extra Help, in which case CMS reassigns you to a stand-alone Part D plan. You can still pick a drug plan during your special enrollment period (December 8, 2026 to February 28, 2027), but January sign-ups start February 1 and February sign-ups start March 1. Until then you pay full price, and once you've gone 63 days or more without drug coverage, a late enrollment penalty can follow you for as long as you have Part D.
Outcomes one and two are the ones you want. Outcome three is what happens to people who set the letter on the counter and forget it.
The federal Part D limits that apply to every drug plan
| Federal Part D limit | 2026 | 2027 |
|---|---|---|
| Maximum deductible a plan can charge | $615 | $700 |
| Out-of-pocket threshold for covered drugs | $2,100 | $2,400 |
| Base beneficiary premium used for the late penalty | $38.99 | $41.33 |

What this means in plain terms: in 2027 no Part D plan can make you pay more than $700 before coverage kicks in, and once your own spending on covered drugs reaches $2,400, you pay nothing more for covered Part D drugs the rest of the year. In the standard benefit you pay 25% coinsurance between those two points, though plans can design things differently. These limits are the same whether you get Part D inside a Medicare Advantage plan or from a stand-alone plan. What differs between plans is which drugs are covered, at what tier, and at which pharmacies. That's why entering your exact drug list and pharmacy into Medicare Plan Finder beats any general comparison.
The late penalty is 1% of the base premium for each full month without coverage. Small per month, but it stays on your premium for as long as you have Medicare drug coverage.
The medical side, briefly
Sumner has no hospital inside city limits on the state Department of Health list. If you're thinking about another Medicare Advantage plan, check the hospital you'd actually use and each doctor in its 2027 network. Under Original Medicare you can see any provider who takes Medicare. If you go that route, Washington law gives you a guaranteed issue right to a Medigap policy because your plan is leaving: insurers can't turn you down or charge more for health reasons. OIC recommends applying on or after November 1, and the right ends March 4, 2027. More on that in the statewide guide for discontinued Medicare plans.
Sumner and Pierce County numbers
- Sumner population, April 1, 2026: 11,080 (WA OFM).
- Sumner residents 65 and older: about 1,700, or 16.1% (Census ACS 2020-2024, margin of error 221).
- Pierce County people with Medicare who already use a stand-alone Part D plan: 44,090 (CMS, July 2026). Those neighbors are a reminder that Original Medicare plus a separate drug plan is a common setup, not an unusual one.
Getting help and getting around in Sumner
The Sumner Senior Center, 15506 62nd Street Court East (253-863-2910), is open 8 a.m. to 4:30 p.m. and serves lunch weekdays at noon (suggested donation $3.50 for guests 60 and over). Staff answer questions and connect people to resources by phone. The city's page also points to the Beyond the Borders Connector, which offers on-demand pickups for seniors and low-income residents to grocery stores, pharmacies and other essentials. Handy if your new drug plan means a different pharmacy.
For longer trips, Sound Transit's Sumner Station is served by the S Line Sounder train and ST Express route 596.
For unbiased Medicare help, SHIBA's statewide line is 800-562-6900, weekdays 8:30 a.m. to 4:30 p.m. Pierce County's local SHIBA listing on the OIC site wasn't taking appointments as of October 26, 2026 and directed callers to 1-800-MEDICARE (1-800-633-4227), so use those two numbers. If you have Apple Health or Extra Help and somehow end up without a drug plan, ask about Medicare's LI NET program, which gives temporary Part D coverage to people who qualify. Countywide details are on the Pierce County page.
Your plan notice sets your dates; federal Medicare rules and Washington law set everything else. Before you switch, confirm it with SHIBA, 1-800-MEDICARE or a licensed agent.
