## title: Supported payers

Stedi supports thousands of medical and dental payers. You can get details about all supported payers through our interactive Payer Network, our Payers API, or the Stedi Agent.

## Find payer details

You can use the following methods to determine:

* The transaction types supported for each payer.
* The payer IDs you need to send transactions through Stedi.
* Which payers support medical, dental, and vision use cases.
* The states and territories where each payer operates.
* Which payers require [transaction enrollment](/healthcare/transaction-enrollment) before you can begin exchanging transactions.

### Payer Network

Visit the [Payer Network](https://www.stedi.com/healthcare/network) to review a searchable list of supported payers.

### Payers API

You can use the following endpoints to search for payers and retrieve their details.

* [Retrieve payer](/healthcare/api-reference/get-payer): Retrieve a specific payer record using the [Stedi payer ID](/healthcare/supported-payers#stedi-payer-id), a unique identifier Stedi assigns to each payer that will never change
* [List Payers JSON](/healthcare/api-reference/get-payers): List all supported payers in JSON format
* [List Payers CSV](/healthcare/api-reference/get-payers-csv): List all supported payers in CSV format
* [Search Payers](/healthcare/api-reference/get-search-payers): Search for payers by name, payer ID, or payer ID alias - fuzzy matching is supported. Results are returned in JSON format.

These endpoints are especially useful when you want to embed payer details or search capabilities into your system or application. For example, you could use the Search Payers endpoint to allow patients to search for and select their insurance provider in a patient intake form.

### Stedi Agent

You can chat with the Stedi Agent to get information about supported payers. To use it, you must be at least an [Operator](/healthcare/accounts-and-billing#members) role within your Stedi account.

To start chatting with the Stedi Agent:

1. Go to the [Chats page](https://portal.stedi.com/app/healthcare/chats) in the Stedi portal.
2. Click **New chat** and select **Payer Finder**.
3. Type your question in the chat window and press **Enter.** For example, you could ask "What is the payer ID for Aetna?" or "Does Cigna support dental use cases?" You can also ask more complex questions, like "Which payers support dental use cases and require transaction enrollment?" Talk to Stedi Agent like you would a human support agent.
4. Ask follow-up questions as needed. You can ask multiple questions about different payers in the same chat.

The Stedi Agent will respond to your questions and display its answers in the chat window.

## Medical, dental, and vision payers

You can determine which payers support medical use cases, dental use cases, vision use cases, or all three.

* The [Payer Network](https://www.stedi.com/healthcare/network) lists **Coverage types** for each payer that indicate supported use cases.
* The [Retrieve Payer](/healthcare/api-reference/get-payer), [List Payers](/healthcare/api-reference/get-payers), and [Search Payers](/healthcare/api-reference/get-search-payers) endpoints return a `coverageTypes` array for each payer indicating supported use cases.

For example, Aetna's **Coverage types** in the network are **Dental, Medical, Vision**. That means you can submit eligibility checks and claims for medical, dental, and vision services to Aetna.

## Operating states

You can determine where payers operate and accept transactions.

* The [Payer Network](https://www.stedi.com/healthcare/network) lists **Operating states** for each payer that indicate where they operate.
* The [Retrieve Payer](/healthcare/api-reference/get-payer), [List Payers](/healthcare/api-reference/get-payers), and [Search Payers](/healthcare/api-reference/get-search-payers) endpoints return an `operatingStates` array for each payer indicating where they operate.

For example, Cigna's **Operating states** in the network are **NATIONAL**, indicating that Cigna operates throughout the entire United States.

## Other names

The Payer Network includes other names for many payers. These additional names help you search for and identify payers using the name most familiar to your organization. For example, “Eaton Benefits Ohio” is an alternative associated with “Cigna”—searching for either name returns the same payer within the database.

## Payer IDs

The Payer Network includes three types of payer IDs. You can use any of these IDs to send transactions through Stedi.

### Primary payer ID (recommended)

The primary payer ID is the most commonly used ID for a payer and most often corresponds to the name the payer uses internally and provides to patients on member ID cards.

When you don't already have a payer ID you use for a particular payer, we recommend using the primary Payer ID.

### Stedi payer ID

The Stedi payer ID is a unique identifier Stedi assigns to each payer. This ID will not change, even if the primary payer ID is updated. We maintain a list of Stedi payer IDs to ensure that 1) you can always refer to a payer using a consistent identifier, 2) we can more easily route requests to the payer through the most reliable connection behind the scenes, and 3) we can update our products without introducing breaking changes.

You may want to use the Stedi payer ID for requests if you are building a system that requires a consistent and immutable set of payer IDs.

### Payer ID aliases

These are alternative IDs associated with a payer. If a payer changes their primary payer ID, payer ID aliases ensure that customers who still refer to the old ID can find the payer and continue sending transactions to the payer uninterrupted. Some payers also have different payer IDs for different plans. Payer ID aliases ensure that requests using these IDs are routed to the same payer.

## Stedi payer errors

Stedi returns the following error messages when a payer is not supported or enrolled properly.

\| Error message | Possible causes and resolutions |
\| ------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
\| `Payer is not configured for {transaction type}. Please contact Stedi support to resolve.` | Stedi does not yet support this transaction type for this payer, or there is a mis-mapping of payer IDs. Contact us with the name of the payer, and we'll investigate the issue. |
\| `Payer connection does not support {transaction type}. Please contact Stedi support to discuss connectivity options.` | Stedi has a connection to this payer, but it doesn't currently support this functionality (real-time eligibility or claim submission). Contact us for a timeline on enabling it. |
\| `Payer is not configured. Please check our published payer list or contact Stedi support to resolve.` | Stedi doesn't recognize the payer ID you provided. Double-check the payer ID in the [Stedi Payer Network](https://www.stedi.com/healthcare/network), or contact us with the name of the payer, and we will help you determine the correct payer ID. |
\| `Payer is not supported. Please contact Stedi support to discuss connectivity options.` | Stedi doesn't yet have connectivity to this payer. We're likely already working on it - contact us for details about the connectivity timeline. |
