Appendix A - Response Codes

Adjudication Response Codes

Standard Canadian Pharmacists Association response codes are attached to a claim when it is returned by PharmaNet, providing information on the status of the claim.

Although the list below can be used as a guide, pharmacists should refer to the latest version of the Canadian Pharmacists Association (CPhA) Pharmacy Claim Standard for the most up-to-date and authoritative listing of adjudication response codes. Note: The series of codes in bold text (MA to NE) are not error codes. These codes are returned in the Drug Use Evaluation (DUE) response status field.
