Inflammatory bowel disease (IBD) SNOMED codes data

FinnGen IBD Task Force Snomed data contains pathology biopsy related Snomed diagnosis codes from IBD patients in FinnGen. Snomed codes are T-snomed which specifies the location of biopsy and M-snomed the morphology. Together these make a pathological diagnosis. M-snomed and T-snomed codes have been harmonized. Different hospitals use different Snomed codes and all have been harmonized into official Snomed coding system.

The data and documentation are available in Sandbox red library:

T_SNOMED_NAME: T-SNOMED name in Snomed coding system

T_SNOMED_TEXT: T-SNOMED free written diagnosis given by the pathologist, usually a combination of T and M Snomed codes

M_SNOMED_CODE: M-SNOMED code in Snomed coding system
