should the mapping for ‘Old rib fractures’ be ‘Late effect of injury’ or ‘Fracture of rib’. I personaly perfer the second one.
Dear @yingzhang, thanks for the finding! It seems that this mapping was automatically assigned on the basis of the similar, but not identical ICD-10 code. You may notice, that the ICD10 code is titled as “Sequelae of other fracture of thorax and pelvis”, thus its mapping somehow corresponds to the mapping rules.
