Data boundary
PlainMedicare presents selected CMS plan-directory fields. It does not calculate a person’s coverage, cost sharing, Medigap options, or enrollment outcome.
One real MA-vs-Original difference: public quality scores
This extract tracks 864 Medicare Advantage contracts from 288 organizations. CMS publishes a public star rating for 83% of them. Original Medicare carries no comparable plan-level quality score, that public rating is a real structural difference this directory can show, not an opinion about which option is better.

Medicare Advantage and Original Medicare: official comparison resources
What PlainMedicare can show
The site can help locate CMS-reported Medicare Advantage plan records, including available directory fields such as a star rating or monthly plan premium when CMS supplies it. Those fields are not a complete comparison of coverage options.
Use the directory to identify a plan record
PlainMedicare’s Medicare Advantage pages are designed to locate sourced CMS plan records by area and insurer. They do not create a complete side-by-side description of coverage arrangements. A directory record is a starting point for research, not a substitute for the current official comparison.
Keep individual circumstances out of a directory comparison
Coverage decisions can turn on circumstances that are not stored in this site’s database. PlainMedicare does not assess eligibility, providers, prescriptions, enrollment status, or a person’s expected use of care. It therefore does not state which coverage option is better for a particular person.
Verify each current source directly
Use Medicare.gov for the official explanation of Medicare coverage and use Plan Compare for current plan-specific information. Review the current primary materials rather than relying on a generalized summary, especially when the question concerns a plan available in a particular county.
Do not calculate a value comparison here
This directory has no complete fee schedules, plan terms, provider-network record, or individual eligibility record. Without those inputs, a total-cost calculation or value ranking would be misleading. PlainMedicare does not perform either calculation.
Separate program information from a recommendation
Official program information can explain terms and processes without deciding what an individual should do. PlainMedicare follows the same boundary: it links to source material and identifies the limits of its own data, but it does not give individualized coverage, medical, or enrollment advice.
Record the source and date when researching
For an auditable comparison, note the official page, plan identifier where relevant, county, and date checked. Those details help a reader return to the source that supported the research and recognize when a current source may have changed since a directory snapshot.
Where to get current information
For official, current Medicare information, see Medicare.gov. For a plan-specific Medicare Advantage comparison, use Medicare.gov Plan Compare. Verify coverage, networks, prescriptions, costs, and enrollment rules with the official service and the plan.
Cost boundary
PlainMedicare does not have the fee schedules, eligibility facts, provider-network information, or benefit terms required to estimate a person’s total costs or compare the value of coverage options. It does not recommend a coverage choice.
A source-first research sequence
- Start with official Medicare information. Use Medicare.gov for current program information and terminology.
- Locate a plan record when relevant. Use the directory to find a CMS-reported plan and its county.
- Check current plan-specific material. Plan Compare and plan documents are the primary sources for plan details.
- Keep the source date with your notes. This shows which current publication supported the research.
- Do not convert research into a recommendation. PlainMedicare does not give individualized coverage or enrollment advice.
Why the boundary matters
A general comparison can identify official sources without deciding a personal coverage question.
Keeping the site’s scope explicit prevents a directory field from being mistaken for a complete comparison.
PlainMedicare describes the limits of its sourced directory data. Medicare.gov remains the authoritative destination for current program and plan information.

Frequently asked questions
Can PlainMedicare tell me which coverage option is right for me?
No. The directory does not provide individualized coverage, cost, or medical advice.
Where can I compare current coverage options?
Use Medicare.gov and Medicare.gov Plan Compare for current, official information and plan-specific details.
Does PlainMedicare model Medigap or cost sharing?
No. It does not publish the fee schedules or eligibility details necessary to model cost sharing, Medigap, or a person’s total costs.
Using the quality-score difference
A star rating is real and public for MA, that alone should not decide the comparison.
- 83% of the 864 MA contracts here carry a rating, use it as one input, not the whole picture. Star ratings guide
- Original Medicare has no plan-level quality score to compare against, so this is a one-sided data point, not a verdict. Medicare.gov basics
- Whichever option you're weighing, confirm providers, prescriptions, and current costs directly. Medicare.gov Plan Compare
Rated-plan share is a CMS directory field, not a recommendation between Medicare Advantage and Original Medicare. Verify current program and plan details on Medicare.gov.
