  "description": "Drug Identification Numbers (DINs) -- the eight-digit number Health Canada assigns to each drug\nproduct approved for sale in Canada.\n\nA DIN identifies one manufacturer's marketed product at one strength and dosage form. It is the\nright code to CARRY when a source has it and the wrong code to MATCH on: the same drug from a\nsecond manufacturer carries a different DIN, and a change of salt changes it again. Ingredient-level\nquestions -- are these two prescriptions the same drug, is this duplicate therapy, does this\nmedication match a recorded allergy -- need an ingredient-level code (CCDD, ATC, or the active\ningredient group number), not a DIN.\n\nPublished by **Health Canada**, which maintains the numbers in the Drug Product Database. Obtain\nthe codes there: <https://health-products.canada.ca/dpd-bdpp/>. Health Canada publishes the\ndatabase openly; no licence gates its use.\n\nThe canonical URI is `http://hl7.org/fhir/NamingSystem/ca-hc-din`, which HL7 Terminology records\nas the official canonical going forward; `http://terminology.hl7.org/CodeSystem/ca-hc-din` is\nretained upstream for backward compatibility. The stable identity across every spelling is the OID\n`2.16.840.1.113883.5.1105`.\n\n**This specification previously fixed `http://hl7.org/fhir/sid/ca-hc-din`, which no publisher\ndeclares.** Stored data and existing integrations may still carry it. **Write the NamingSystem\nform; be liberal in what you accept when reading** -- treat the spellings above as the same code\nsystem until your own data no longer carries the others. This release does not migrate stored\n`Coding.system` values.\n\n**The set enumerates no codes of its own.** It includes the whole system, so it means every code in it, and it exists so the system URI resolves to a definition rather than to nothing. The definition itself stays with the publisher at the canonical above: this specification does not redefine the system and does not restrict it. Where this page shows a list of codes, that list is a SAMPLE reproduced under the publisher's own terms and is not the set's content -- the page says how many of how many it is showing.",
