Handle ACH dishonored returns and contested dishonored returns in an ODFI workflow

Steps

1. A dishonored return is an R-code entry sent by the ODFI back to the RDFI when an original return was improper; receive dishonored returns (R61–R67 code range) via your ACH operator file within the NACHA-specified window
2. Parse the dishonored return code to determine the reason: R61 (misrouted return), R67 (duplicate return), R68 (untimely return), R69 (field error in original return), R70 (permissible return not accepted) — each requires a different remediation path
3. For R61 (misrouted), re-route the original return to the correct RDFI and notify your ACH operator of the error
4. For R67/R68 (duplicate or untimely return), investigate your return processing pipeline for the defect and do not re-originate the original debit without the originator's instruction
5. If you choose to contest a dishonored return, file a contested dishonored return within the NACHA window; document the grounds and retain evidence that the original return was proper
6. Update your payment record status to dishonored_return and route the exception to your ACH operations team for manual resolution; notify the originator of the outcome
