# Get policy by ID
URL: https://backworkhealth.com/docs/api/getPolicy

Retrieve a single coverage policy by its ID.

**Endpoint:** `GET /api/v1/policies/{id}`

**Availability:** Live in production.

**Authentication:** API key in `Authorization: Bearer <key>` with the `read` scope.

Retrieve a single coverage policy by its ID. Use `include` to fetch criteria, codes, attachments, or version history. Policy text sections are fair-use excerpts; the full text is at `source_url`.

**Parameters**

* `id` (path, required): Policy ID (e.g., L33831)
* `include` (query): Additional data to include (comma-separated: criteria, codes, attachments, versions)

**Code sources:** Code entries in the response carry a `source`: `document` when the policy document lists the code, `inferred_title_match` when the code was attached because the policy title names the drug. See [Code sources](/docs/code-sources).

**Example request**

```bash
curl -X GET "https://backworkhealth.com/api/v1/policies/L33831?include=criteria%2Ccodes%2Cattachments%2Cversions" \
  -H "Authorization: Bearer $BACKWORK_API_KEY"
```

**Example response** (`200`)
