  "description": "The Canadian Clinical Drug Data Set (CCDD) -- the pan-Canadian terminology for identifying and\nnaming medications and some medical devices, designed to reflect current clinical practice and\nsafety advice.\n\nIt codes drugs at the INGREDIENT level, which is the level at which every cross-record question is\nactually asked: same-drug detection, duplicate therapy, and matching a medication against a recorded\nallergy. This specification prefers it over ATC where a source has it, and prefers either over a\nDIN, which identifies a marketed product rather than a drug. Pinned on the `ccdd` slice of\n`MedicationRequest`, `MedicationStatement`, `MedicationDispense` and `AllergyIntolerance`.\n\nPublished by **Health Canada**; the FHIR representation is developed and served by **Canada Health\nInfoway**, which also takes content-change requests (clinicaldrug@infoway-inforoute.ca). CCDD is\n**freely available** for use in digital health solutions, in English and Canadian French; no licence\nfee gates it. The FHIR representation is browsable through Infoway's terminology service at\n<https://terminologystandardsservice.ca/fhir>.\n\nThe canonical URI is `http://terminology.hl7.org/CodeSystem/hc-CCDD`, published through HL7\nTerminology (THO). An earlier Infoway-hosted URI\n(`https://fhir.infoway-inforoute.ca/CodeSystem/canadianclinicaldrugdataset`) is maintained upstream\nfor backward compatibility; this specification pins the THO form, which is the one THO records as\nofficial going forward.\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.",
