Score Hierarchy
Complete mapping from internal validation scores (0–7) to user-facing canonical rate scores (1–5).
Score Mapping
| Internal Score | Label | Canonical Score (1–5) | Meaning | Decimal Component |
|---|---|---|---|---|
| 7.x | Validated | 5 | Payer + hospital agree within ±20% | rate / 1e8 (prefer higher rates) |
| 6.x | Raw, not outlier | 4 | Single source, within bounds | CDF value (prefer common rates) |
| 5.x | Benchmark-validated | 3 | Transformed rate within 95–1000% of Medicare | CDF value |
| 4.x | Not outlier | 2 | Within bounds, no validation | CDF value |
| 3.x | Imputation benchmark | 3 | Imputation, benchmark-based | CDF value |
| 2.x | Imputation not outlier | 2 | Imputation within bounds | CDF value |
| 1.x | Outlier | 1 | Outside all acceptable bounds | CDF value |
| 0 | No rate | 0 | NULL / no rate available | — |
The decimal tiebreaker is everything
Among 100 payer rates that all score 6.x (raw, not outlier), the one with the highest CDF (most common rate value) wins. Among validated rates (7.x), the one with the highest dollar amount wins. This ensures deterministic selection without arbitrary ordering.
