Compare Medicare Advantage plans in your county

Data boundary

Plan availability, star ratings, and a CMS plan-premium field are not a complete cost or coverage comparison. PlainMedicare does not calculate personalised costs or recommend a plan.

Why 'your county' is the right starting point

CMS-reported plan inventory ranges from 1 to 145 plans across 3,147 counties, averaging 41.9 per county. A national plan count is close to meaningless; the same insurer's plan may not even be sold in a neighboring county.

Counts are CMS-reported plan availability per county (counties table), not a quality or cost ranking. See methodology.

Start with the CMS record

Browse states and counties to locate plans reported for the relevant area. A directory page can help identify a plan record and its published CMS fields.

Confirm that the county is the right place to start

County pages are a way to locate CMS-reported plan records for an area. They are not a finding that a person can enroll in a plan, receive a service, or use a provider. Confirm the relevant location and the plan’s current service area with the official source before relying on a record.

Read each displayed field as a directory field

Availability, a star rating, and a monthly premium field each describe different published information. None of those fields is a complete measure of coverage, quality for an individual, benefit value, or total cost. PlainMedicare presents the fields without combining them into a score or recommendation.

Verify current plan materials

After locating a plan record, use the official service to open current plan information for the relevant county. Check the plan’s materials directly for the details that matter to the situation under review. A directory entry can help identify what to verify, but it cannot replace the current primary materials.

Do not treat a missing field as a conclusion

Public datasets can omit a field, use a different reporting period, or change their format. A blank or unavailable directory field is not evidence that a plan has no feature, no charge, or no network. Verify the current plan material instead of drawing a conclusion from a missing value.

Keep comparisons reproducible

For research, record the plan name or identifier, county, source page, and date checked. That creates a clear trail back to the primary source and makes it easier to see when a later publication changes a plan record. It also avoids treating a directory snapshot as a permanent plan description.

PlainMedicare does not rank plans by value

This directory does not compute a composite comparison, estimate savings, or say which plan is best for a person. Those claims would require complete, current inputs that are not in the database. Use the official comparison service for a current, person-specific review instead.

Verify the decision with the primary service

Use Medicare.gov Plan Compare for a current comparison. Check the plan’s service area, provider network, drug coverage, costs, and benefit details for the person and county involved. These details can change and are not fully represented in PlainMedicare’s data.

Do not use illustrative arithmetic

PlainMedicare does not publish a complete fee schedule, drug-price record, provider billing record, or supplemental-benefit valuation. For that reason, this site does not estimate annual costs, rank plans by value, or model what a particular person should pay.

A reproducible research sequence

  1. Locate the county record. Start with the county and plan identifier in the CMS directory data.
  2. Check the current official record. Use Plan Compare for the plan and location being researched.
  3. Read current plan documents. Treat the plan’s current materials as the source for terms and details.
  4. Record the date checked. Published plan information may not match an older directory snapshot.
  5. Keep the result descriptive. Do not translate sourced fields into a personal plan recommendation.

Frequently asked questions

What can I compare on PlainMedicare?

The directory can show CMS-reported plan availability, star ratings, and monthly plan premiums where CMS provides that field.

Can I compare my total annual cost here?

No. PlainMedicare does not have the complete, person-specific cost and benefit data needed to calculate total annual cost.

Where should I verify a specific plan?

Use Medicare.gov Plan Compare and the plan’s current materials to verify coverage, network, formulary, and current costs.

Starting your county search

Plan inventory is a county-level fact, treat it that way before comparing anything else.

  • A county in the 50+ plans bucket has far more to filter through than one with a handful of plans, adjust how much research a comparison needs accordingly. Browse by state
  • Plan availability by county changes year to year, always confirm the plan is still offered where you live. Medicare.gov Plan Compare
  • Once you have a county shortlist, star ratings are the next CMS-sourced filter, not a coverage guarantee. Star ratings guide

County plan counts are a CMS directory field, not a cost or coverage comparison. Verify current plan details on Medicare.gov before enrolling.
