### Additional Observations

**Machine-Readable Price Transparency Files Review**

* **MRFs Up-to-Date:** ✔️ Yes, the MRFs are kept up to date each month.
* **Table of Contents Accessibility:** ✔️ The Table of Contents link is easily accessible.
* **Table of Contents Formatting:** ✔️ Yes, the Table of Contents is properly formatted.
* **File Download Barriers:** ❌ Several files linked in the Table of Contents are not accessible.
* **File Accessibility Percentage:** ❌ only a few of the files are accessible and several of those have no data. Several files are corrupted (see below).

**Overall Assessment:** CareSource remains one of the least compliant Payers in the country.

Not only do they have .zip files nested within .zip files for several layers, but they also are not putting the correct fields into their machine-readable files. See the screenshot and description below:

<figure><img src="/files/MCku9ZcFR047QNxNZHxR" alt=""><figcaption></figcaption></figure>

The issues:

1. The main key is `in_networks` instead of `in_network` (it is not supposed to be plural)
2. The Price field should be negotiated\_price
3. The Exp\_Date field should be expiration\_date
4. The Expiration Date should not have a timestamp

These are easily-fixable issues and we hope CareSource will make the necessary changes to their files.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.payerset.com/payers/caresource-price-transparency.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
