Enrollment requirements

Workflow considerations

Common questions

Can I submit 837P and 837I claims electronically to this payer?

Yes, both professional claims through 837P and institutional claims through 837I are supported after the practice completes payer enrollment.

Does this payer support electronic eligibility checks?

Yes, eligibility and benefits inquiries use the 270/271 transaction pair. The separate coordination-of-benefits 271 transaction is not supported.

Can I receive ERA 835 from this payer?

Yes, ERA 835 is supported after payer enrollment. EFT and combined ERA/EFT are not supported, so electronic remittance does not provide electronic funds transfer.

Can I send attachments or coordination-of-benefits information electronically?

No. Electronic attachments through 275 and coordination-of-benefits 271 are not supported, so use your established alternative workflow.
