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.

Most HMO plans in Oklahoma rate 4 stars or better.

34 of 39 plans here carry an overall rating of at least 4 stars. Where ratings cluster this high they stop being a useful way to sort plans — network, drug coverage and out-of-pocket limits will separate these more than the star count will.

Oklahoma HMO plans rank 15th of 49 on star rating.

Across the 38 rated plans here the average overall rating is 3.96 stars, 15th highest of the 49 states with HMO plans. Ratings apply to the contract, so every plan a carrier files under one contract shares the same score.

Common questions

Oklahoma Medicare Advantage HMO plans, answered

How much do Medicare Advantage HMO plans cost in Oklahoma?
Of the Oklahoma HMO plans with a published premium, 97% charge $0 a month. 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, which averages $6,424 across these plans.
What are the star ratings for Oklahoma HMO plans?
The 38 rated HMO plans in Oklahoma average 3.96 out of 5 stars, with 34 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 Oklahoma?
There are 39 HMO plans from 9 carriers, sold across 77 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. 12 of them are Special Needs Plans with extra eligibility rules (see below).
Do Oklahoma HMO plans include prescription drug coverage?
39 of the 39 HMO plans here bundle Part D drug coverage into the plan. That is the usual arrangement for Medicare Advantage and there is no separate drug premium for it — the plan premium covers 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 Oklahoma?
12 of the 39 HMO plans in Oklahoma 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.
