| Source | The data | Years |
|---|---|---|
| Every plan | ||
| Plans and benefits | Every qualified health plan: metal level, deductibles, copays, the out-of-pocket max, covered benefits, per plan year. | 2014 to 2026 |
| Premiums | By plan, rating area and age, per plan year. | 2014 to 2026 |
| Where each plan sells | Service areas and counties per issuer; the network and the machine-readable file each plan points to. | 2014 to 2026 |
| Which plan became which | The crosswalk from one plan year to the next: renewed, replaced, discontinued. | 2015 to 2026 |
| Plans in the states that run their own exchange | The same plan, benefit, rate, service area, network and rule files for the states not on HealthCare.gov, kept apart from the federal files. With them every state and DC is covered each plan year; where a state is in both, the state file is its small-group exchange. | 2016 to 2026 |
| Who bought, and what they paid for | ||
| Enrollment | Effectuated enrollment monthly by state, and by issuer and geography, for the federal and state exchanges. | 2014 to 2026 |
| Enrollment by parent company | Every exchange issuer tied to its legal entity, insurance group and parent, as it was each year and as it is today; enrollment summed by parent, state and nation, federal and state exchanges apart. | 2014 to 2026 |
| Claims, appeals and denials | What issuers report about claims received, denied and appealed, per plan. | 2017 to 2026 |
| Quality and experience | Star ratings per plan, the nationwide quality ratings by issuer, and the enrollee survey. | 2017 to 2026 |
| The money behind it | ||
| Rate filings | What issuers asked for and why, from the unified rate review filings. | 2024 to 2026 |
| Risk adjustment transfers | What moved between issuers in each state's individual and small-group markets. | 2021 to 2025 |
| Insurer financials | Every commercial insurer's medical loss ratio filing by state and market: premium, claims, member months, quality spend, taxes and fees, tied to its insurance group. | 2017 to 2024 |
| What is not here | ||
| Network breadth is what the issuer reports, not measured. State-based exchanges publish on their own clocks; seven are in. | ||
| Never public: enrollment below the issuer and county level. | ||
