Retail deduction codes, by retailer.

Search the code that appears on a remittance, then review the plain-English category, evidence considerations, and current public source.

Important: Retailer deduction information changes. We use public sources and label them, but the retailer portal and current supplier documentation should always be treated as the controlling source before a dispute is filed.
