Which insurers and states are covered

Every dataset has gaps. Most vendors let you find them after you have signed. Here is what is in the April 2026 build, what is not, and what we are still fixing.

The 37 insurers in the build

These are loaded and queryable today. How deep each goes varies by state, so every row tells you how many rates and how many providers are behind it and you can judge that yourself.

The 30 insurers with coverage rules

The coverage corpus is a different set from the rate corpus, and a larger one. Several of these publish their medical policy openly but no usable rate file, so they appear here and not above.

The 30 insurers where we hold both

The joined dataset can only exist where we hold rates and rules for the same insurer. Every insurer in the coverage corpus also appears in the rate build, so the coverage side is what bounds it. This is matched on names against the build manifest; the verified crosswalk is being built separately and this list will be re-derived from it.

Not in the rate build

Parsed but not loaded into this vintage. A scheduled addition, not a surprise. If your work depends on one of them, tell us before you license anything.

How deep each state goes

All 50 states and the District of Columbia are covered, but not equally. This is the real depth per state in the current drug build — how many codes have a published rate, how many distinct providers sit behind them, and what the middle rate looks like against the federal benchmark.

Billing codes

More than 350,000 codes appear in the data. A code only has a row where an insurer published a rate for it, so a missing code means it was not disclosed — not that we failed to parse it. Specialty and infusion drug codes, and the administration codes that go with them, are the best-covered part.
