# Cost centers, rate tables, and the code library

> The reference data behind billing: cost centers scope funding, rate tables set price, the crosswalk picks the code, and the code library validates it.

Behind every billing row is a small set of reference data that turns a shift into a priced, coded claim. It lives under Billing settings. You mostly maintain cost centers; the rest is platform-managed reference data you read and rely on. This guide walks each piece and how they fit together.

## Cost centers: your funding sources

A cost center is a funding source that scopes billing — "payer kind, contract number, and DODD handling." Open `Cost Centers` to see them, listed by `Name`, `Payer`, `Exclude DODD`, and `Status`.

1. Click `Create Cost Center`.
2. Give it a `Name` and, optionally, a `Description`.
3. Set the `Payer kind` — `MEDICAID_WAIVER`, `COUNTY_BOARD`, `PRIVATE_PAY`, `MRC`, or `OTHER`.
4. Enter the `Contract number` (a `7-digit DODD contract number`); leave it blank to fall back to your tenant default.
5. Tick `Exclude from DODD` for funding that shouldn't flow to DODD, keep `Active` on, and `Save`.

Each cost center can also carry `Custom Codes` — per-client billing-code or rate overrides for the cases that don't fit the standard tables.

## Rate tables set the price

`Rate Tables` are `Platform-managed · view only` — Enmantle keeps them in sync with DODD rates, so there's nothing to edit. There's one table per service family: `HPC`, `HPC Transport`, `ADS / VocHab`, `NMT`, `LPS`, `PDP`, `RAL`, `AFL`, `Foster`, and `Shared Living`. Each row has an `ID`, a rate (stored in cents), and an `Effective` date range, plus the dimensions that service uses (staff and group size, ODDP range, vehicle type, and so on).

## The service crosswalk picks the code

The `Service Crosswalk` maps "each ServiceType to one or more BillingCodes. Add conditions (program, group size) to disambiguate." Use `Add mapping` to link a service type to a DODD billing code, with `Program` and `Group Size` conditions and a `Priority` to break ties. This is what lets a single service resolve to the right code for the client's waiver and shift size.

## The code library validates the code

The `Code Library` is the `Platform-managed · view only` catalog of DODD billing codes. Each entry lists the `Code`, `Title`, `Program`, `Category`, `Unit Type`, `Effective` window, and whether `EVV` is required. Alongside it, `Counties (CODB)` maps each county to its CODB number for pricing.

## How they fit together

When a shift derives into a billing row on the `Setup` step, these pieces work in order: the crosswalk picks the billing code, the code library validates it, the county's CODB plus the matching rate table price it, and the cost center scopes the funding source and contract number. Set them up once and every row prices and codes itself.

> Because rate tables, the code library, and county CODB numbers are platform-managed, you never chase a rate update — Enmantle keeps HPC and the rest current for you.
