Enrollment requirements
- Electronic remittance (ERA 835): one click enrollment, typically takes weeks
Plan your electronic workflow
- Run a 270/271 eligibility and benefits check before visits, and review the 271 coordination-of-benefits response when other coverage may apply.
- Choose 837D, 837I, or 837P according to the claim type, then use 276/277 to monitor claim status.
- Complete payer enrollment paperwork before relying on 835 ERA delivery; until enrollment is active, maintain a manual remittance workflow.
- Plan payment reconciliation without EFT, since electronic funds transfer is unavailable even when ERA is enabled.
- Do not expect 275 attachments to transmit electronically; use the payer’s required alternative for supporting documentation.
