Frequently Asked Questions
- Is the formulary checker free?
- Yes. It's completely free and needs no account or login.
- Where does the coverage data come from?
- Medicare Part D coverage comes from the free CMS quarterly formulary files. When those files haven't been loaded into an environment, the tool shows a notice instead of guessing.
- Can I check commercial or employer plans?
- Not yet. Commercial and employer formularies aren't public data, so only Medicare Part D coverage is available today.
