ClinicalVersion used [Identifier] TNM classification
Definition
A code that indicates the edition of the AJCC manual used to stage the case. This applies to the manually coded AJCC fields. It does not apply to the Derived AJCC T, N, M and AJCC Stage Group fields [2940, 2960, 2980, and 3000]. TNM codes have changed over time and conversion is not always simple. Therefore, a case-specific indicator is needed to allow grouping of cases for comparison... NAACCR Data Standards and Data Dictionary Version 11
