What the county lookup can verify
Every county record has a plan entry, not every field is always published
The county availability lookup below queries 131,985 state x county x plan records from the CMS 2026 Landscape file. Not every field is present for every one, so the lookup returns more for some plans than others.
- County plan records 100% 131,985
Every row the county lookup can match on state and FIPS code.
- CMS star rating available 89% 118,027
The plan carries a published CMS 2026 overall star rating.
- Premium & deductible available 85% 111,730
Both a monthly premium and an annual deductible are on file.
- Enrollment count available 0% 0
Never published in this CMS Landscape extract, so a lookup cannot return it.
