Just pointing out that the following valid,standard SNOMED concepts all have the same concept_name
concept_code concept_name concept_id
402556000 Malignant melanoma 4299429
402558004 Malignant melanoma 4291272
372244006 Malignant melanoma 4162276
Making it impossible to distinguish, yet when looked up on line I get
402556000 Malignant melanoma (radial growth phase) (disorder)
402558004 Malignant melanoma (vertical growth phase) (disorder)
372244006 Malignant melanoma (disorder)
Yes, known problem of SNOMED. Will need to fix on our side (just pick one by some hierarchy based heuristic).
