42061-2

LOINC code 42061-2 identifies "Follow-up source Cancer registry". This field is created by the central registry. It records the source from which the consolidated information was obtained on a patient's vital status and date of last contact. Follow-up Source Central would be updated when new or more reliable information becomes available. However, when the existing date of last contact/vital status is deemed to be more reliable than newly obtained information, then neither the date of last contact/vital status nor the follow-up source central would be changed. For central registries performing follow-up, this field could help evaluate the success rates of various methods of follow-up. When new follow-up information conflicts with the existing information, knowing the follow-up source can help resolve any discrepancies. Because follow-up information includes follow-up address and cancer status as well as date of last contact/vital status, and may come from different sources, it is important to note that Follow-up Source Central refers to the two fields, date of last contact and vital status. ..
