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.
However, the concept of “T91.201 Old rib fractures” has to be remapped. Could you please create the GitHub issue here?
