# International and Finnish Health Code Sets

Finnish health registries consist of several specific code sets in order to trace healthcare data.

The main code sets used are:

* **Diagnosis codes**: ICD[8](https://www.julkari.fi/handle/10024/135324)/[9](https://www.julkari.fi/handle/10024/131850)/[10](https://www.julkari.fi/handle/10024/80324), [ICPC2](https://www.who.int/standards/classifications/other-classifications/international-classification-of-primary-care)
* **Operation codes**: [Nomesco- Finnish version](https://www.julkari.fi/bitstream/handle/10024/104401/URN_ISBN_978-952-245-858-2.pdf?sequence=1), [Nomesco](http://norden.diva-portal.org/smash/get/diva2:968721/FULLTEXT01.pdf), [Finnish Hospital league](https://version.helsinki.fi/ontology-group/ontologists/-/wikis/uploads/c6f5830c1ebc4b22025cd4b04090bc7d/Sairaalaliitto1983toimenpidekoodit.pdf) and Demanding Heart Patient (new/old coding), SPAT (Finnish primary care outpatient procedures)
* **Medication codes**: [ATC](https://www.whocc.no/atc_ddd_index/), Drug reimbursement, [VNR](https://wiki.vnr.fi/?page_id=36)
* **Cancer codes**: [ICD-O-3](https://apps.who.int/iris/bitstream/handle/10665/96612/9789241548496_eng.pdf)
* **Service Sector codes:** [FGVisitType](https://github.com/FINNGEN/FinOMOP_OMOP_vocabulary/tree/main/VOCABULARIES/FGVisitType)

The main registry data file in FinnGen is the [Detailed Longitudinal Data](/finngen-data-specifics/red-library-data-individual-level-data/what-phenotype-files-are-available-in-sandbox-1/detailed-longitudinal-data.md). It contains all of the above code sets, but these code sets may also be used in [other registry data](/finngen-data-specifics/red-library-data-individual-level-data/what-phenotype-files-are-available-in-sandbox-1/other-registers.md) in FinnGen, like [visual impairment registry data](/finngen-data-specifics/red-library-data-individual-level-data/what-phenotype-files-are-available-in-sandbox-1/other-registers.md), [reproductive history data](/finngen-data-specifics/red-library-data-individual-level-data/what-phenotype-files-are-available-in-sandbox-1/other-registers.md), [cervix and breast cancer screening data](/finngen-data-specifics/red-library-data-individual-level-data/what-phenotype-files-are-available-in-sandbox-1/other-registers.md) and [vaccination registry data](/finngen-data-specifics/red-library-data-individual-level-data/what-phenotype-files-are-available-in-sandbox-1/other-registers.md).
