Common questions

Can I submit professional or institutional claims electronically to this payer?

Yes, 837P and 837I are supported after your practice completes payer enrollment. They are not available before enrollment is completed.

Can I verify eligibility and benefits electronically?

Yes, standard eligibility and benefits requests use 270/271 after enrollment. Coordination-of-benefits 271 transactions are not supported.

Does this payer support ERA or EFT?

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

How do I check claim status or send attachments?

Neither claim status 276/277 nor attachments 275 is supported. Use the payer's separate approved process for those needs.
