CPHA: D.56.03 DIN/GP/PIN and D.63.03 Unlisted Compound

Drug Identification Number (DIN) or General Product identification number (GP#) assigned by the Health Protection Branch. If the product or compound does not have a DIN or GP#, the product identification number (PIN) assigned by the Canadian Pharmacists Association.

For compounds, which do not have an assigned PIN, the DIN of the eligible active ingredient with the highest total cost is to be used. Compounds must be described in Field D.63.03.

These code sets are managed externally and therefore the complete list of medication codes will not be included in this specificaiton. Code systems that are used are listed below|
