# Supported Service Type Codes (STCs) by payer > Get supported Service Type Codes (STCs) by healthcare payer for eligibility checks, including commonly supported codes for major payers. Published Jan 29, 2026 Category: Guide To verify insurance or health benefits with an eligibility check, most payers require a [Service Type Code (STC)](https://www.stedi.com/docs/healthcare/eligibility-stc-procedure-codes). The STC tells the payer what kind of benefits information you want back – mental health, vision, urgent care, and so on. But not every payer accepts every STC. There are over 150 [HIPAA-adopted STCs](https://www.stedi.com/docs/healthcare/eligibility-stc-procedure-codes#full-stc-list). Most payers support only a small subset of those codes. How do you know which STCs a payer will accept? For the best results, you need to [test each STC](https://www.stedi.com/docs/healthcare/eligibility-stc-procedure-codes#test-payer-stc-support) with each payer. This guide gives you a head start. It includes a table of STCs supported by Stedi’s top payers based on payer documentation. **Note:** We've published a [CPT and HCPCS to Service Type Code lookup tool](https://www.stedi.com/cpt-hcpcs-to-stc). Use it to get the latest recommended mappings. ## Supported STCs by payer The table below lists supported STCs for 50 of Stedi’s top payers, sorted by eligibility volume in December 2025. Together, they represent over 65% of Stedi's eligibility check volume. The listed STCs come from payer and third-party documentation as published at the time of writing. Not all payers are included. For definitions of each code, see the [STC code list](https://www.stedi.com/docs/healthcare/eligibility-stc-procedure-codes#test-payer-stc-support) in the Stedi docs. **Important:** Treat this table as a starting point, not a source of truth. Payer documentation may be wrong, incomplete, or outdated. Always [validate STC support](https://www.stedi.com/docs/healthcare/eligibility-stc-procedure-codes#test-payer-stc-support). Unsupported STCs may still return a baseline response. See [How payers handle unsupported STCs](https://www.stedi.com/blog/supported-service-type-codes-by-payer#how-payers-handle-unsupported-stcs). **Use one STC per request** When running eligibility checks, only include one STC per request unless you’ve confirmed the payer supports multiple STCs. For best practices, see our [docs](https://www.stedi.com/docs/healthcare/eligibility-stc-procedure-codes#choose-the-right-stc). | **Payer name** | **Primary payer ID** | **Stedi Payer ID** |

in an eligibility request, and the patient is covered, many medical payers return a [baseline response](https://www.stedi.com/docs/healthcare/eligibility-stc-procedure-codes#general-benefit-checks) for a [standard, HIPAA-mandated set of STCs](https://www.stedi.com/docs/healthcare/eligibility-stc-procedure-codes#general-benefit-checks). If you send an unsupported STC to a payer in an eligibility request, the payer may return: - A response with a [benefits information code](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-eligibility-legacy#response.benefitsInformation.code) of `V` (Cannot Process) or no benefits information - A [baseline response](https://www.stedi.com/docs/healthcare/eligibility-stc-procedure-codes#general-benefit-checks). - A [AAA error](https://www.stedi.com/docs/healthcare/eligibility-troubleshooting#payer-aaa-errors), such as `42` (Unable to Respond at Current Time) - A rejection of the request using a 999 Implementation Acknowledgement, indicating the request was invalid for processing Behavior varies by payer. Just because you receive a successful response from a payer doesn’t mean the payer supports the STC. The payer may return a [baseline response](https://www.stedi.com/docs/healthcare/eligibility-stc-procedure-codes#general-benefit-checks) with benefits information unrelated to the STC you requested. ## Process eligibility checks with Stedi Stedi lets you run HIPAA-compliant real-time and batch eligibility checks using our [JSON API endpoints](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-eligibility-legacy). We also support [X12](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-eligibility-raw-x12), [SOAP](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-eligibility-soap), and – for batch checks – [CSV](https://www.stedi.com/docs/healthcare/batch-refresh-eligibility-checks#upload-csv-file). If you’re new to Stedi, you can try out mock eligibility checks on a free account. [Signup](https://portal.stedi.com/auth/sign-up-intent) takes less than two minutes. No credit card is needed.
