Composite quality score
Across 5 federal sources, snapshot 2026-05-26. A weighted mean of source-level completeness, inter-source consistency, ingestion lag, and the OIG LEIE byte-level match rate. Recomputed hourly; the machine-readable twin lives at /quality.json.

Methodology
The composite is a weighted mean of four sub-metrics — completeness, consistency, match rate, and timeliness. Versioned, peer-reviewable, snapshot-anchored.
For each source, the median proportion of public-displayable required fields that are non-null and non-empty across rows in the latest snapshot. Snapshots over 100k rows are sampled to 10k uniformly — see methodology.
| Source family | Last snapshot | Row count | Median field completeness |
|---|---|---|---|
| NPPES (NPI registry) | 7.8M | 99.1% | |
| OIG LEIE exclusions | 68K | 99.8% | |
| CMS PECOS PPEF | 2.5M | 97.4% |
Where two independent federal feeds describe the same NPI, do they agree? Each rate is the share of NPIs whose normalized value matches across both sources. The denominator is the set of NPIs present in both snapshots with a non-null value on each side.
Specialty agreement: NPPES taxonomy ↔ PECOS enrollment
94.2% agreement · denominator 1.8M NPIs
Active-status agreement: NPPES ↔ PECOS
96.1% agreement · denominator 2.1M NPIs
Wall-clock hours between an upstream publication and Fonteum ingesting it. Computed over the trailing 90 days; the p95 number is the worst-case ninety-fifth percentile, not a synthetic SLA.
