 ## Tables
 
 | Table | Rows | What it holds |
 | --- | ---: | --- |
-| `rate_fact` | 304,709,442 | One row per distinct rate fact: a billing code, a provider set and a price list, with the set of networks it appears in (`ns_id`). Sorted by code. 16 parts by billing code. |
-| `network_set` | 13,688 | `ns_id` -> the sorted list of `network_id`s sharing those facts. One file per `rate_fact` part, so a set can repeat across files. |

+| `network_set` | 13,826 | `ns_id` -> the sorted list of `network_id`s sharing those facts. One file per `rate_fact` part, so a set can repeat across files. |
 | `network` | 124 | One row per derived network: distinct file content (size and gzip trailer). |
 | `source_file` | 124 | One row per source file: name, URL, size, gzip fingerprint, header, counts, parser flags, and its `network_id`. |
 | `code` | 116,566 | Billing codes as published (type, version, code, arrangement), keyed by `code_id`. Descriptor text is withheld where it is licensed (see below). |
-| `provider_set` | 1,659,291 | `ps_id` -> the provider groups (`pg_ids`) a rate applies to. |
+| `provider_set` | 1,659,804 | `ps_id` -> the provider lists (`pli_ids`) a rate applies to. Its ID is the hash of the flattened, sorted group list. |
+| `provider_list` | 130,324 | `pli_id` -> the provider groups (`pg_ids`) of one provider reference as published. |
 | `provider_group` | 664,715 | `pg_id` -> TIN (type, normalized value, raw values) and sorted NPI list; `tin_wide` when the file lists NPI 0 (the whole TIN). Business names are hints only. |
 | `price_list` | 28,290,701 | `pl_id` -> the price terms (`pt_ids`) of one negotiated_prices list. |
 | `price_term` | 9,390,706 | `pt_id` -> one negotiated price: type, amount (`rate_e4` = dollars x 10,000, plus `rate_raw` exactly as published), billing class, setting, service codes, modifiers, expiration date, additional information, parsed revenue-code ranges and flags. |
