Median out-of-pocket max

Across the 121 HMO plans in Missouri that publish one, the in-network out-of-pocket maximum has a median of $5,500 and tops out at $9,850 — the ceiling on what you pay in a year for covered in-network care. The mean is $6,254, 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.

45% of Missouri's HMO plans are Special Needs Plans.

54 of 121 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.

Missouri HMO plans rank 25th of 49 on star rating.

Across the 119 rated plans here the average overall rating is 3.72 stars, 25th 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

Missouri Medicare Advantage HMO plans, answered

How much do Medicare Advantage HMO plans cost in Missouri?
Of the Missouri HMO plans with a published premium, 80% 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 $5,500 across these plans.
What are the star ratings for Missouri HMO plans?
The 119 rated HMO plans in Missouri average 3.72 out of 5 stars, with 56 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 Missouri?
There are 121 HMO plans from 12 carriers, sold across 115 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. 54 of them are Special Needs Plans with extra eligibility rules (see below).
Do Missouri HMO plans include prescription drug coverage?
116 of the 121 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 Missouri?
54 of the 121 HMO plans in Missouri 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.
