Common questions

Can I send institutional claims (837I) to this payer electronically?

Yes. Institutional claims (837I) are available immediately, without waiting for enrollment required for other supported transactions.

Are professional claims (837P) supported?

Yes, but only after the practice completes payer enrollment. Do not treat 837P as available immediately.

Can I check eligibility and benefits electronically?

Yes, after enrollment, using the 270/271 eligibility and benefits transactions. Coordination-of-benefits transactions are not supported, so eligibility support does not include COB processing.

Are ERA and EFT supported for this payer?

ERA (835) is supported after enrollment. EFT and combined ERA/EFT are not supported.
