> You can now submit multiple claims in an 837 transaction when using X12 over SFTP. Professional, dental, and institutional claims are supported.

Product: Claims

You can now submit multiple claims in a single 837 transaction set using X12 over [SFTP](https://www.stedi.com/docs/healthcare/submit-claims-sftp-connection). [837P professional](https://www.stedi.com/docs/healthcare/submit-professional-claims), [837D dental](https://www.stedi.com/docs/healthcare/submit-dental-claims), and [837I institutional](https://www.stedi.com/docs/healthcare/submit-institutional-claims) claims are supported.

Some billing platforms create a single 837 transaction set (one `ST`/`SE` segment) that includes multiple claims from different billing providers or patients. The transaction set may include claims for different payers. To deliver the claims to the correct payer, the X12 must be split into separate 837 transactions.

Stedi automatically splits 837 transaction sets containing multiple claims at the Billing Provider (`2000A`), Subscriber (`2000B`), and Claim Information (`2300`) loops. Behind the scenes, Stedi creates separate 837 transactions for each claim and routes them to the payer independently. Multiple claims going to the same payer will also be split to maintain the same behavior across all 837 transactions.

For example, if your 837 transaction set has two billing providers (two `2000A` loops), each with three subscribers (three `2000B` loops), and two claims per subscriber (two `2300` loops), Stedi submits 12 separate claim transactions.

**Pricing**  
Stedi charges for each split claim transaction. For example, if a transaction set would result in 12 claim transactions, you're billed for 12 claim submissions. For rates, see our pricing page or [contact us](https://www.stedi.com/contact).

**Claim acknowledgments and ERAs**  
The Stedi portal’s **Transactions** page will only display one 837 transaction, representing the original X12 file, and you’ll receive a single [999 acknowledgment](https://www.stedi.com/docs/healthcare/submit-claims-sftp-retrieve-responses#interpret-999s). However, [277CA claim acknowledgments](https://www.stedi.com/docs/healthcare/claim-responses-overview#277ca-claim-acknowledgment) – from Stedi and the payer – and [835 Electronic Remittance Advices (ERAs)](https://www.stedi.com/docs/healthcare/test-claims-workflow#test-responses) will reference the split 837 claims. Stedi will also run claim edits on the split 837 claims to catch rejections early.

If you submit a batch X12 claim to the [Stedi Test Payer](https://www.stedi.com/docs/healthcare/test-claims-workflow#enroll-with-the-stedi-test-payer) (Payer ID: `STEDITEST`), each transaction receives its own mock [835 Electronic Remittance Advice (ERA)](https://www.stedi.com/docs/healthcare/test-claims-workflow#test-responses).
