Enrollment requirements

• Electronic remittance (ERA 835): one click enrollment, typically takes weeks

Plan the billing workflow

• Use 270/271 eligibility checks before visits; if a needed check cannot be completed, verify coverage through your established payer workflow.
• Submit 837P, 837D, or 837I based on the claim type, then use 276/277 to monitor claim status.
• Complete payer enrollment before expecting 835 ERA files in Hero EMR; plan manual remittance posting until enrollment is active.
• Use your existing payment process because EFT and combined ERA/EFT are unavailable through this payer connection.
• Do not rely on electronic COB processing or attachments; this payer does not support coordination-of-benefits 271 or 275 transactions.
