Nacha's definition

The source document to which an ARC, BOC, or POP Entry relates has been presented for payment.

Verbatim from Nacha — ISO 20022 Guide to Mapping U.S. ACH Return Items and Notifications of Change, August 2023, Version 2.01 (Table 1, return reason codes) (return reason code table). Applies to: ARC, BOC, POP.

How it appears in an ISO 20022 statement

Nacha's mapping guide marks this code as not currently supported or mapped for camt.053 (footnote 1): it applies to Standard Entry Class codes or flows the guide does not cover, so it has no published ISO 20022 reason-code mapping.

Return time frame

Nacha's R10/R11 rule page describes R37 as a 60-day return made with the Receiver's signed or similarly authenticated Written Statement of Unauthorized Debit.

Source: Nacha — rule page 'Differentiating Unauthorized Return Reasons' (R10 / R11; effective 1 April 2020 and 1 April 2021)

Can the entry be reinitiated?

Nacha's reinitiation rule governs resubmission of returned debit entries; it does not arise for this code. See the definition and the operator note for what the return means and who acts on it.

Source: Nacha — rule page 'ACH Network Risk and Enforcement Topics' (unauthorized return rate threshold; reinitiation of entries)

What an operator does next

The paper check behind an ARC, BOC or POP entry was itself presented and paid — the Receiver has paid the same obligation a second time. Refund promptly and check your check-conversion controls for the source document.

PaymentBrief guidance, not Nacha text. Your ODFI's procedures and the current Nacha Operating Rules govern.

Where ACH debit returns sit in the mandate and collection lifecycle, and how the return-rate thresholds bear on your ODFI relationship.
Confidence: high. Status: verified. The Nacha Operating Rules govern. Nacha sells them and they were not used here; every statement above is taken from a public Nacha document or a public US Treasury or Federal Reserve document, named per statement. Where those documents are silent, this card says so of those documents — it is not a claim about everything Nacha has published.
