Median out-of-pocket max

Across the 84 HMO plans in Washington that publish one, the in-network out-of-pocket maximum has a median of $7,150 and tops out at $9,850 — the ceiling on what you pay in a year for covered in-network care. The mean is $7,541, which sits above the median — the spread is not symmetric, so the median is the better guide.

A $0 plan premium is not a free plan. You still pay your Part B premium to Medicare, plus copays and coinsurance as you use care. Star ratings are published by CMS per contract, so every plan a carrier files under the same contract shares one rating — it describes the carrier’s performance, not this specific plan’s benefits. Estimate your real costs.

42% of Washington's HMO plans are Special Needs Plans.

35 of 84 plans here are SNPs — restricted to people who also have Medicaid, live in an institution, or have a qualifying chronic condition. If none of those apply to you the field is smaller than the headline count suggests, so filter them out before comparing.

24 of Washington's HMO plans carry no star rating yet.

CMS rates a contract, not a plan, and does not rate one that is too new or has too little data — so 24 plans here shows no rating at all. Unrated is not the same as badly rated; it usually means a new contract, and those plans have to be judged on benefits and network instead.

Common questions

Washington Medicare Advantage HMO plans, answered

How much do Medicare Advantage HMO plans cost in Washington?
Of the Washington HMO plans with a published premium, 69% charge $0 a month. The monthly premium is what you pay the plan for its medical (Part C) and drug (Part D) coverage together. A $0 premium does not mean the plan is free: you still pay your Part B premium to Medicare, plus copays and coinsurance as you use care. The number that actually caps a bad year is the in-network out-of-pocket maximum, with a median of $7,150 across these plans.
What are the star ratings for Washington HMO plans?
The 60 rated HMO plans in Washington average 3.88 out of 5 stars, with 31 rating 4 or better. CMS rates a contract rather than an individual plan, so every plan a carrier files under the same contract shares one score. A contract that is too new or has too little data is not rated at all, which is different from rating badly.
How many Medicare Advantage HMO plans are available in Washington?
There are 84 HMO plans from 14 carriers, sold across 39 counties. Availability is set by county, so the plans you can actually join depend on where you live — the full list is rarely available in any one place. 35 of them are Special Needs Plans with extra eligibility rules (see below).
Do Washington HMO plans include prescription drug coverage?
81 of the 84 HMO plans here bundle Part D drug coverage into the plan. That is the usual arrangement for Medicare Advantage, and you pay one monthly premium to the plan — but that premium has a medical (Part C) part and a drug (Part D) part, and the drug part is often what makes it more than $0. Each plan's page shows both. If you join a Medicare Advantage plan without drug coverage, you generally cannot add a standalone Part D plan alongside it.
What is a Special Needs Plan, and are there any in Washington?
35 of the 84 HMO plans in Washington are Special Needs Plans. SNPs limit enrollment to people who also have Medicaid, live in a nursing home or similar institution, or have a qualifying chronic condition. They often carry richer benefits for that group, but if you do not meet the criteria you cannot join one — so the real number of plans open to you may be lower than the total.

A $0 premium is not the whole cost.
