Marketplace plan information comes from the CMS Marketplace Public Use Files (PUF), published by the Centers for Medicare & Medicaid Services (U.S. Government, public domain).

What source is used

The annual CMS Marketplace PUF datasets describing qualified health plans offered through the Health Insurance Marketplace (HealthCare.gov).

What data is imported

Plan-level public attributes by plan year:

Plan identifiers, issuer, metal level, and plan type.
Published rates, benefits/cost-sharing, and network/service-area attributes as reported in the PUF.

How often it is refreshed

CMS publishes the PUF annually around the open-enrollment cycle. We import on a recurring schedule; each view shows the plan year and import date.

How records are matched

Plans are organized by their official plan and issuer identifiers and service area. Marketplace plan data is reference data — it is not matched to individual providers.

What confidence means

Confidence here applies to dataset linkage (plan/issuer identifiers and periods), not to a guarantee that a plan is currently offered to you.

What the data can and cannot prove

Can: show what plans published for a plan year — metal level, rates, benefits, and network attributes as filed.
Cannot: guarantee current availability, exact premiums after subsidies, or whether a specific provider is in-network today. Verify plan availability, network, rates, benefits, and enrollment details with official Marketplace (HealthCare.gov) or insurer sources before enrolling.

Limitations

PUF data is point-in-time and filed in advance; plans, networks, and rates change. This is not insurance or medical advice.

Report a data issue

If a plan attribute looks wrong, please contact us with the plan ID and what you observed. Authoritative plan details live with the Marketplace and the insurer; we never alter the official source.
